Keflex Suspension (cephalexin) is a prescription antibiotic used to treat various bacterial infections, including respiratory tract infections, ear infections, skin and soft tissue infections, urinary tract infections, and certain bone infections.
Keflex contains cephalexin, an active ingredient belonging to a class of antibiotics called first-generation cephalosporins.
Cephalosporin antibiotics work by interfering with the formation of bacterial cell walls. These walls protect bacteria and help them maintain their structure.
When cephalexin prevents bacteria from building strong cell walls, the bacteria become damaged and eventually die.
This helps the body’s immune system clear the infection and relieve symptoms.
Keflex Suspension is available as an oral liquid, making it particularly useful for children and people who have difficulty swallowing tablets or capsules.
The medication is commonly available in strengths of 125 mg/5 mL and 250 mg/5 mL, although available formulations may vary by country.
Keflex Suspension treats infections caused by bacteria that are susceptible to cephalexin. It does not treat viral infections such as the common cold, influenza, or most viral sore throats.
Your healthcare provider will determine whether Keflex Suspension is appropriate based on the type of infection, its severity, your medical history, and your response to treatment.
Keflex Suspension may be prescribed to treat certain bacterial respiratory tract infections.
Respiratory tract infections affect structures involved in breathing, including the throat, tonsils, and other parts of the respiratory system.
These infections can cause inflammation, discomfort, and difficulty performing normal activities.
Keflex may be used for respiratory infections caused by susceptible bacteria, particularly certain strains of Streptococcus pneumoniae and Streptococcus pyogenes, when appropriate.
Common symptoms of bacterial respiratory infections may include:
Keflex Suspension may be prescribed for certain bacterial throat infections, including streptococcal pharyngitis.
Streptococcal pharyngitis, commonly called strep throat, is caused by group A Streptococcus bacteria.
Symptoms may include a sudden sore throat, fever, swollen tonsils, and tender lymph nodes.
Cephalexin works by damaging bacterial cell walls, helping eliminate the bacteria responsible for the infection.
Keflex may be an alternative treatment for selected patients who cannot take certain first-line antibiotics. However, it is not appropriate for everyone with a penicillin allergy, particularly those with a history of immediate or severe allergic reactions.
Most sore throats are caused by viruses and do not require antibiotics.
Your healthcare provider may recommend a throat swab or rapid strep test to confirm whether antibiotic treatment is necessary.
Keflex Suspension may be used to treat certain bacterial middle ear infections, also called otitis media.
Otitis media develops when fluid builds up behind the eardrum and becomes infected.
Middle ear infections are particularly common in children, although adults can also develop them.
Possible symptoms include:
Keflex may be effective against certain susceptible bacteria that cause middle ear infections.
However, cephalexin is not usually a first-choice antibiotic for acute otitis media because it does not reliably cover all common bacteria responsible for this condition.
Your healthcare provider will determine whether Keflex is suitable based on the suspected bacteria, local antibiotic resistance patterns, and your medical history.
Not every ear infection requires antibiotics. Some infections improve without antibiotic treatment, particularly when symptoms are mild.
Keflex Suspension is commonly used to treat bacterial skin and soft tissue infections.
Skin infections can develop when bacteria enter the body through cuts, scratches, insect bites, or damaged skin.
These infections may affect the outer layers of the skin or extend into deeper tissues.
Cephalexin is active against certain susceptible bacteria, including methicillin-sensitive Staphylococcus aureus (MSSA) and Streptococcus pyogenes.
Skin conditions that may be treated with Keflex include:
Common symptoms of skin infections include redness, warmth, swelling, tenderness, and pain.
Some infections may also cause pus, crusting, or fever.
Keflex works by destroying susceptible bacteria, helping reduce infection and allowing the affected skin to heal.
However, Keflex does not reliably treat infections caused by methicillin-resistant Staphylococcus aureus (MRSA).
Certain skin abscesses may also require drainage rather than antibiotic treatment alone.
Your healthcare provider will assess the affected area and determine whether Keflex Suspension is the appropriate treatment.
Keflex Suspension may be prescribed to treat certain bacterial urinary tract infections.
A urinary tract infection occurs when bacteria enter and multiply within the urinary system.
The urinary tract includes the kidneys, ureters, bladder, and urethra.
Most uncomplicated UTIs affect the bladder, causing a condition called cystitis.
Common symptoms include:
Keflex may be used for urinary tract infections caused by susceptible bacteria, including certain strains of Escherichia coli, Klebsiella pneumoniae, and Proteus mirabilis.
The medication enters the bloodstream after oral administration and is eliminated mainly through the kidneys.
This allows cephalexin to reach concentrations in the urine that can help treat susceptible bacterial infections.
Your healthcare provider may request a urine test or urine culture to identify the bacteria responsible for the infection.
Because some bacteria are resistant to cephalexin, treatment may need to be adjusted based on laboratory results.
Seek prompt medical attention if you experience fever, chills, flank pain, or vomiting, as these may indicate a kidney infection that requires further evaluation.
Keflex Suspension may also be used to treat certain bacterial bone infections, known as osteomyelitis.
Osteomyelitis occurs when bacteria infect bone tissue, causing inflammation and potentially damaging the affected bone.
Bacteria may reach the bone through the bloodstream, a nearby infection, or an injury that exposes deeper tissues.
Symptoms of osteomyelitis may include:
Keflex may be prescribed for bone infections caused by susceptible bacteria, particularly certain strains of Staphylococcus aureus and Proteus mirabilis.
However, bone infections can be serious and often require prolonged antibiotic treatment.
Some patients may need intravenous antibiotics, surgery, or other treatments depending on the severity of the infection.
Your healthcare provider may recommend imaging tests, blood tests, or bacterial cultures to determine the most appropriate treatment.
Although Keflex is indicated for certain bone infections, it is not an appropriate treatment for every type of osteomyelitis.
Bacterial joint infections, also called septic arthritis, affect the fluid and tissues inside a joint.
They may cause severe pain, swelling, warmth, fever, and difficulty moving the affected joint.
Although cephalexin may sometimes be used as part of a specialist-directed treatment plan for infections involving bones or joints, Keflex is not specifically approved for every type of bacterial joint infection.
Septic arthritis is a medical emergency because bacteria can rapidly damage joint structures.
Treatment often requires urgent joint drainage and antibiotics selected according to the bacteria involved.
Do not attempt to treat a suspected joint infection with leftover Keflex or another antibiotic without medical evaluation.
Keflex Suspension contains cephalexin, a first-generation cephalosporin antibiotic that kills susceptible bacteria by interfering with bacterial cell wall formation.
Bacteria need strong cell walls to maintain their shape, protect their internal structures, and survive.
Cephalexin blocks proteins that bacteria use to build and maintain these protective walls.
These proteins are called penicillin-binding proteins (PBPs).
When cephalexin binds to these proteins, the bacteria cannot properly form their cell walls.
As a result, the bacterial walls weaken, and the bacteria eventually break apart and die.
This action is called a bactericidal effect, meaning the antibiotic kills bacteria rather than simply slowing their growth.
Inhibits Bacterial Cell Wall Synthesis
Bacterial cell walls contain a substance called peptidoglycan, which provides strength and structural support.
During bacterial growth and multiplication, new peptidoglycan must be produced and connected to the existing cell wall.
Cephalexin interferes with this process by binding to penicillin-binding proteins.
Without a properly formed cell wall, bacteria become vulnerable to damage and destruction.
Helps Eliminate Susceptible Bacteria
Keflex is effective against certain Gram-positive and Gram-negative bacteria.
Susceptible bacteria may include:
However, not all strains of these bacteria respond to cephalexin.
Some bacteria have developed antibiotic resistance, allowing them to survive treatment.
Your healthcare provider may recommend bacterial culture and susceptibility testing when appropriate to identify whether Keflex is likely to work.
Supports Recovery From Bacterial Infections
As Keflex destroys susceptible bacteria, the body’s immune system helps clear the infection.
Symptoms such as fever, swelling, redness, and discomfort may gradually improve as the infection responds to treatment.
Some people begin noticing improvement within the first few days, although recovery depends on the type and severity of the infection.
Certain infections, especially bone infections, may require longer treatment and additional medical care.
Keflex Suspension begins acting against susceptible bacteria after the medication is absorbed into the bloodstream.
Cephalexin is generally absorbed relatively quickly after oral administration, with peak blood concentrations commonly occurring about one hour after a dose.
However, this does not mean that infection symptoms will disappear within one hour.
For many uncomplicated bacterial infections, noticeable improvement may occur within 24 to 72 hours after starting treatment.
Skin redness, swelling, fever, or urinary symptoms may gradually decrease as the bacterial infection responds.
More serious infections may take longer to improve.
Your healthcare provider will determine the appropriate dosage and treatment duration based on the infection, age, body weight, kidney function, and other medical factors.
Take Keflex Suspension at the prescribed intervals and complete the treatment course as directed, even if your symptoms improve earlier.
Do not stop, shorten, or extend treatment without medical advice.
Contact your healthcare provider if your symptoms become worse or fail to improve within the expected period.
Keflex Suspension is intended for bacterial infections and should only be used when a bacterial cause is confirmed or strongly suspected.
It does not treat viral infections and should not be used unnecessarily.
Common side effects may include diarrhea, nausea, vomiting, and abdominal discomfort.
Tell your healthcare provider if you have previously experienced an allergic reaction to cephalexin, another cephalosporin antibiotic, or a penicillin antibiotic.
People with reduced kidney function may require dosage adjustments because cephalexin is primarily eliminated through the kidneys.
Seek urgent medical attention if you experience difficulty breathing, facial swelling, or a severe skin reaction.
Contact your healthcare provider if you develop severe or persistent diarrhea, particularly if accompanied by abdominal pain, fever, or blood in the stool.
Keflex Suspension helps treat susceptible bacterial infections by disrupting bacterial cell wall formation. It may be prescribed for certain respiratory, ear, skin, urinary tract, and bone infections, but the correct treatment depends on the bacteria involved.
The oral suspension form of cephalexin is usually taken by mouth every 6 to 12 hours, depending on the severity of the infection being treated and the patient’s age and weight. Take it orally as directed by your doctor or healthcare provider. Shake the bottle well before use. You can take it with or without food but taking it with food can help to reduce the risk of stomach upset or nausea.
Take cephalexin at around the same times every day. Follow the directions on your prescription label carefully and ask your doctor or pharmacist to explain any part you do not understand. Take cephalexin exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.
Keflex Suspension (Cephalexin) is available in the following forms and strength:
Before taking Keflex Suspension, tell your healthcare provider about any medical conditions, allergies, or medications you are taking.
Keflex Suspension is a prescription antibiotic used to treat certain bacterial infections, including respiratory tract infections, ear infections, skin and soft tissue infections, urinary tract infections, and bone infections.
Keflex contains cephalexin, an active ingredient belonging to a class of medications called first-generation cephalosporin antibiotics.
Cephalexin works by interfering with bacterial cell wall formation. This weakens the protective walls surrounding susceptible bacteria, causing them to break apart and die.
Although Keflex Suspension is generally well tolerated, it may cause side effects or serious complications in certain individuals, particularly those with antibiotic allergies, kidney disease, or a history of seizures.
Your healthcare provider will determine whether Keflex Suspension is appropriate based on your medical history, type of infection, kidney function, and other medications.
Do not take Keflex Suspension if you have a known allergy to cephalexin or another cephalosporin antibiotic.
Before starting treatment, tell your healthcare provider if you have previously experienced an allergic reaction to antibiotics, particularly penicillins or cephalosporins.
Cephalexin belongs to a group of antibiotics called beta-lactams. Some people with allergies to other beta-lactam antibiotics may also react to cephalexin.
However, having a penicillin allergy does not automatically mean you are allergic to every cephalosporin. Your healthcare provider will assess the type and severity of your previous reaction.
Allergic reactions may range from mild skin symptoms to severe, potentially life-threatening reactions.
Possible symptoms include:
Serious allergic reactions, including anaphylaxis, have been reported with cephalexin.
Certain severe skin reactions may also cause blistering, peeling skin, fever, or painful sores inside the mouth.
Stop taking Keflex Suspension and seek emergency medical attention if you experience difficulty breathing, swelling of the tongue or throat, or a severe blistering skin reaction.
Tell your healthcare provider about all previous medication allergies before starting treatment.Â
Keflex Suspension should be used with caution in people with kidney disease or reduced kidney function.
The kidneys play an important role in removing cephalexin from the body.
After the medication enters the bloodstream, most of it is eliminated through the kidneys and passed out in urine.
When kidney function is reduced, the body may eliminate cephalexin more slowly.
This can cause the medication to accumulate in the bloodstream, potentially increasing the risk of side effects.
People with significant kidney impairment may require a lower dosage or longer intervals between doses.
Your healthcare provider may assess kidney function using blood tests that measure creatinine levels and calculate kidney filtration capacity.
Possible signs of kidney problems include:
Kidney disease may develop without noticeable symptoms, making medical monitoring important.
Tell your healthcare provider if you have chronic kidney disease, previously experienced kidney problems, or receive dialysis.
Severely reduced kidney function may increase the risk of neurological side effects, including seizures, particularly if the cephalexin dosage is not adjusted.
Do not change your prescribed dosage without medical advice.Â
Keflex Suspension may cause gastrointestinal side effects, including diarrhea, nausea, vomiting, and abdominal discomfort.
Antibiotics work by destroying or preventing the growth of susceptible bacteria.
However, they may also affect beneficial bacteria that normally live in the intestines.
These bacteria help maintain digestive health and prevent certain harmful microorganisms from growing excessively.
When antibiotics disrupt the normal balance of intestinal bacteria, digestive symptoms may develop.
Common gastrointestinal side effects include:
Mild digestive symptoms may improve as treatment continues or after the medication is finished.
However, severe or persistent diarrhea can indicate a more serious problem.
Clostridioides Difficile-Associated Diarrhea
Keflex Suspension may increase the risk of an intestinal infection caused by Clostridioides difficile, commonly called C. difficile.
This bacterium can multiply when antibiotic treatment disrupts the normal balance of bacteria in the intestines.
Possible symptoms include:
Contact your healthcare provider promptly if you develop severe, persistent, or bloody diarrhea while taking Keflex Suspension.
Do not take anti-diarrheal medications without medical advice if C. difficile infection is suspected.
Your healthcare provider may recommend stool testing or specific treatment depending on your symptoms.Â
Keflex Suspension may interact with certain prescription medications, over-the-counter products, and other treatments.
Some interactions may affect how cephalexin is eliminated from the body, while others may change the effects of medications taken at the same time.
Before starting Keflex Suspension, tell your healthcare provider about all medications, vitamins, supplements, and herbal products you take.
Important medication interactions include:
Metformin
Metformin is a medication commonly prescribed to help control blood sugar levels in people with type 2 diabetes.
Taking cephalexin with metformin may increase the amount of metformin in the bloodstream.
This occurs because cephalexin can reduce the rate at which metformin is eliminated through the kidneys.
Higher metformin concentrations may increase the risk of certain side effects, particularly in people with impaired kidney function.
Your healthcare provider may recommend closer blood sugar monitoring or adjust your metformin dosage when necessary.
Probenecid
Probenecid is a medication used to treat certain conditions, including gout.
It works partly by changing how the kidneys eliminate substances from the body.
Probenecid can reduce the elimination of cephalexin, causing higher antibiotic concentrations in the bloodstream.
Because of this interaction, taking probenecid and cephalexin together is generally not recommended.
Blood-Thinning Medications
Tell your healthcare provider if you take anticoagulants, such as warfarin.
Certain antibiotics may affect bleeding risk or interfere with the management of anticoagulant treatment.
Your healthcare provider may recommend additional monitoring, particularly if you have other risk factors for abnormal bleeding.
Do not stop or change your medications without medical advice.
Tell your healthcare provider if you are pregnant, planning to become pregnant, or breastfeeding before taking Keflex Suspension.
Cephalexin has been used to treat bacterial infections during pregnancy, and available studies have not established an increased risk of major birth defects or miscarriage associated with its use.
Cephalexin is generally considered an antibiotic that may be used during pregnancy when treatment is medically necessary.
However, your healthcare provider should still assess the infection, medical history, and appropriate dosage before prescribing it.
Untreated bacterial infections can also cause complications during pregnancy, making appropriate antibiotic treatment important.
Cephalexin passes into human breast milk in small amounts.
Available information suggests that the amount transferred to breastfed infants is generally low.
Cephalexin is usually considered compatible with breastfeeding when prescribed appropriately.
However, some breastfed infants may develop mild digestive symptoms, such as loose stools, or changes in their normal intestinal bacteria.
Rarely, infants may experience a rash or oral thrush.
Tell your healthcare provider if your baby develops persistent diarrhea, unusual feeding difficulties, or a new rash while you are taking Keflex Suspension.
Pregnancy or breastfeeding does not automatically prevent the use of cephalexin. Your healthcare provider will determine whether the medication is appropriate based on the expected benefits and possible risks.Â
Keflex Suspension should be used with caution in people with a history of seizures, epilepsy, or certain neurological conditions.
Cephalexin belongs to the cephalosporin class of antibiotics, which has been associated with seizures in some patients.
The risk is particularly important in people with reduced kidney function.
When the kidneys cannot eliminate cephalexin efficiently, the medication may accumulate in the bloodstream.
Excessive antibiotic concentrations can increase the risk of adverse effects involving the nervous system.
Possible warning signs include:
Tell your healthcare provider if you have epilepsy, a history of seizures, or reduced kidney function.
Your healthcare provider may adjust your antibiotic dosage or recommend additional monitoring.
Do not stop taking prescribed seizure medications without medical advice.
Seek emergency medical attention if you experience a first-time seizure, repeated seizures without recovery, or a seizure lasting five minutes or longer.
If a seizure occurs during Keflex treatment, urgent medical assessment is necessary to determine whether the antibiotic should be discontinued or changed.Â
Tell your healthcare provider if you have liver disease or a history of abnormal liver function tests before taking Keflex Suspension.
Although cephalexin is primarily eliminated through the kidneys, the medication has occasionally been associated with changes in liver function.
Some patients have experienced temporary increases in liver enzyme levels during treatment.
Rare cases of liver inflammation, including hepatitis and cholestatic jaundice, have also been reported.
Cholestatic jaundice occurs when bile flow from the liver becomes impaired, causing bilirubin to accumulate in the body.
Possible symptoms of liver problems include:
Liver injury associated with cephalexin is uncommon, and routine dosage reductions are not generally required solely because a patient has liver disease.
However, your healthcare provider may recommend additional monitoring if you have significant liver impairment or develop symptoms suggesting liver injury.
Contact your healthcare provider promptly if you experience jaundice, dark urine, or persistent upper abdominal pain during treatment.
Do not adjust your Keflex dosage without medical advice.Â
Keflex Suspension may rarely affect normal blood clotting.
Certain cephalosporin antibiotics have been associated with prolonged prothrombin time, which means the blood takes longer than normal to clot.
Blood clotting is an important process that helps stop bleeding after an injury.
When clotting becomes impaired, a person may bruise or bleed more easily.
People with certain medical conditions may have an increased risk of bleeding complications, including those with kidney disease, liver disease, poor nutritional status, or a history of bleeding disorders.
The risk may also be higher in patients receiving anticoagulant medications.
Possible symptoms include:
Tell your healthcare provider if you have a bleeding disorder, vitamin K deficiency, liver disease, or take blood-thinning medication.
Your healthcare provider may recommend additional blood tests if you have risk factors for abnormal bleeding.
For patients taking warfarin, monitoring of the international normalized ratio (INR) may be appropriate.
Seek urgent medical attention if you experience significant or unexplained bleeding.
Do not discontinue prescribed blood-thinning medications without consulting your healthcare provider.Â
Tell your healthcare provider if you have diabetes before taking Keflex Suspension.
Cephalexin is not generally known to cause significant changes in blood sugar levels directly.
However, bacterial infections can affect glucose regulation, particularly in people with diabetes.
During an infection, the body releases hormones that help respond to illness and inflammation.
Some of these hormones may increase blood sugar levels or make them more difficult to control.
Changes in appetite, fluid intake, and physical activity during illness may also affect glucose readings.
Your healthcare provider may recommend checking your blood sugar more frequently while you are being treated for a bacterial infection.
If you take metformin for type 2 diabetes, tell your healthcare provider before starting Keflex Suspension.
Cephalexin may increase metformin concentrations in the bloodstream by reducing its elimination through the kidneys.
Your healthcare provider may recommend additional monitoring or a temporary medication adjustment, depending on your kidney function and overall health.
Cephalexin may interfere with certain laboratory tests used to detect glucose in urine.
Some older chemical testing methods, including Benedict’s solution and Fehling’s solution, may produce a false-positive urine glucose result.
This means the test may indicate that glucose is present even when the result does not accurately reflect the actual amount.
Modern enzyme-based blood glucose tests are not affected by this specific interference.
Tell your healthcare provider or laboratory personnel that you are taking Keflex Suspension if you are scheduled for urine glucose testing.
Continue monitoring your blood sugar according to your diabetes management plan.Â
Keflex Suspension should only be used when a bacterial infection is confirmed or strongly suspected.
Using antibiotics when they are not needed can contribute to antibiotic resistance.
Antibiotic resistance develops when bacteria acquire the ability to survive medications that previously killed them.
Over time, resistant bacteria may become more difficult to treat.
Prolonged or repeated use of Keflex may also allow certain microorganisms that are not susceptible to cephalexin to grow excessively.
This can sometimes lead to secondary infections, including oral thrush or vaginal yeast infections.
Possible symptoms include:
Take Keflex Suspension exactly as prescribed and complete the prescribed treatment course unless your healthcare provider instructs you otherwise.
Do not use leftover antibiotics to treat a new illness.
Do not share your medication with another person, even if they have similar symptoms.
Contact your healthcare provider if your infection does not improve or becomes worse during treatment.
Contact your healthcare provider if you experience persistent nausea, diarrhea, abdominal pain, unusual bruising, worsening infection symptoms, or other unexpected effects while taking Keflex Suspension.
Tell your healthcare provider if you have kidney disease, liver problems, diabetes, a seizure disorder, or a history of antibiotic allergies.
Seek prompt medical attention if you develop severe or persistent diarrhea, jaundice, unusual bleeding, or new neurological symptoms.
Seek emergency medical attention if you experience difficulty breathing, swelling of the tongue or throat, a serious skin reaction, or a seizure.
Keflex Suspension can help treat susceptible bacterial infections, but safe treatment depends on the correct dosage, careful review of medication allergies, and appropriate monitoring. Following your prescribed treatment plan and reporting unusual symptoms can help reduce the risk of complications.
If you forget to take a dose of Keflex Suspension, take the missed dose as soon as you remember. However, if it is almost time for your next scheduled dose, skip the missed dose and continue with your regular dosing schedule. Keflex Suspension is a prescription antibiotic used to treat certain bacterial infections, including respiratory tract infections, ear infections, skin infections, urinary tract infections, and bone infections. Taking Keflex at the prescribed intervals helps maintain effective antibiotic levels in your body, allowing the medication to fight susceptible bacteria. Missing doses frequently may reduce the effectiveness of treatment and make it harder to clear the infection. Do not take two doses together to make up for a missed dose. Taking extra cephalexin may increase the risk of side effects, including nausea, vomiting, diarrhea, and abdominal discomfort. If you miss several doses or are unsure when to take your next dose, contact your healthcare provider or pharmacist. Continue taking Keflex Suspension for the full prescribed treatment duration unless your healthcare provider instructs you otherwise. Do not stop taking the antibiotic simply because your symptoms improve.
Yes, Keflex Suspension can be taken with or without food. However, taking it with a meal or snack may help reduce stomach-related side effects. Keflex contains cephalexin, a first-generation cephalosporin antibiotic that works by interfering with bacterial cell wall formation. The medication is absorbed through the digestive system after oral administration. Food may slightly slow how quickly cephalexin is absorbed, but it generally does not significantly reduce the total amount of medication absorbed. Some people experience nausea, abdominal discomfort, or an upset stomach while taking antibiotics. Taking Keflex Suspension with food may make these symptoms easier to manage. If your healthcare provider has not given you specific instructions about food, you can choose whether to take the medication with meals or on an empty stomach based on how well you tolerate it. Shake the bottle well before each dose to ensure the medication is evenly distributed throughout the liquid. Use an oral syringe or an appropriate medication-measuring device to measure the prescribed dose accurately. Avoid using household teaspoons, which may not provide an accurate measurement. Take the medication at the prescribed intervals and follow your healthcare provider’s instructions throughout treatment. Contact your healthcare provider if you experience persistent nausea, vomiting, severe abdominal pain, or diarrhea.
Keflex Suspension begins working against susceptible bacteria shortly after the medication is absorbed into your bloodstream. Cephalexin works by blocking bacterial cell wall formation, weakening the protective structures that bacteria need to survive. The medication is generally absorbed quickly after oral administration, with peak blood concentrations typically reached within approximately one hour. However, the antibiotic starting to work does not mean your symptoms will disappear immediately. For many uncomplicated bacterial infections, noticeable improvement may occur within 24 to 72 hours after starting treatment. For example, people taking Keflex for certain skin infections may notice that redness, swelling, and tenderness gradually decrease during the first few days. Those receiving treatment for urinary tract infections may experience less burning during urination and reduced urinary urgency as the infection responds. However, more serious infections, including certain bone infections, may require longer treatment before significant improvements occur. The time needed for recovery depends on several factors, including the type of bacteria, severity of the infection, location of the infection, and your overall health. Take Keflex Suspension exactly as prescribed, even if you begin feeling better before completing treatment. Do not increase your dosage or shorten the prescribed treatment course without consulting your healthcare provider. If your symptoms become worse or do not begin improving within approximately 48 to 72 hours, contact your healthcare provider for further evaluation. Some infections may require a different antibiotic or additional treatment, particularly if the bacteria are resistant to cephalexin.
No, Keflex Suspension cannot treat viral infections such as the common cold, influenza (flu), or most viral sore throats. Keflex contains cephalexin, an antibiotic that works specifically against certain types of bacteria. It destroys susceptible bacteria by interfering with the formation of their cell walls. Viruses are different from bacteria. They do not have bacterial cell walls and reproduce by entering and using the body’s cells. Because cephalexin targets bacterial cell wall formation, it does not work against viruses. Taking Keflex Suspension for a viral infection will not shorten the illness, relieve symptoms caused by the virus, or prevent the infection from spreading. Unnecessary antibiotic use may also cause side effects, including diarrhea, nausea, allergic reactions, and disruption of beneficial intestinal bacteria. Frequent or inappropriate antibiotic use can contribute to antibiotic resistance, making certain bacterial infections more difficult to treat in the future. Most common colds and uncomplicated viral respiratory infections improve without antibiotics. However, some people may develop a secondary bacterial infection during or after a viral illness. If your healthcare provider determines that a bacterial infection is present, an antibiotic may be prescribed when appropriate. Only use Keflex Suspension for a bacterial infection when prescribed by your healthcare provider. Do not take leftover antibiotics or share prescribed medication with another person.
