Prezista (active ingredient: darunavir) is a prescription medication used to treat HIV-1 infection.
It is used together with other antiretroviral medications as part of a complete HIV treatment plan.
HIV-1 is a virus that attacks the immune system, especially certain white blood cells called CD4 cells.
Without treatment, HIV can weaken the immune system over time and make it harder for the body to fight infections.
Prezista helps reduce the amount of HIV in the blood and helps support immune system function.
Prezista may be used in adults and in certain children 3 years of age and older, depending on the child’s weight, treatment history, and healthcare provider’s recommendation.
The dose may be different for children and adults.
Prezista belongs to a group of HIV medications called protease inhibitors.
HIV uses an enzyme called protease to cut newly made viral proteins into the correct pieces needed to create mature, infectious virus particles.
Darunavir blocks this protease enzyme.
When HIV protease is blocked, newly produced virus particles cannot mature properly.
This reduces the virus’s ability to make new infectious copies of itself and helps lower the amount of HIV in the blood.
Prezista is not used alone.
It is usually taken with other antiretroviral medicines and is often given with a medication that increases darunavir levels in the body, such as ritonavir or cobicistat, depending on the treatment plan.
Using several HIV medications together helps control the virus more effectively and reduces the chance that HIV will become resistant to treatment.
Prezista helps control HIV, but it does not cure the infection.
Regular treatment can help keep the amount of virus in the blood very low and allow the immune system to stay stronger.
Take Prezista exactly as prescribed and do not skip doses or stop treatment without speaking with your healthcare provider.
Missing doses can allow HIV to multiply and may increase the risk of the virus becoming resistant to your medications.
Prezista comes as a tablet taken by mouth.
It must be taken together with other HIV medications as part of a complete treatment plan. Depending on your treatment history and prescribed regimen, Prezista may be taken once or twice daily.
Prezista should be taken with food.
Food helps your body absorb darunavir properly and allows the medication to work as intended.
Take Prezista at about the same time or times each day.
Swallow the tablet with water.
Do not crush or chew the tablet unless your healthcare provider or pharmacist tells you it is safe to do so.
Prezista is usually taken with a medication that increases the amount of darunavir in your body, such as ritonavir or cobicistat.
These medications help Prezista stay at an effective level in the bloodstream.
Take all parts of your HIV treatment exactly as prescribed.
For some adults who do not have darunavir resistance, a common regimen is Prezista 800 mg once daily with ritonavir 100 mg once daily, taken with food.
Other patients may need a twice-daily regimen, depending on previous HIV treatment, resistance testing, and other medical factors.
Your healthcare provider will determine the correct dose for you.
In children, the dose of Prezista is based mainly on body weight, age, treatment history, and other HIV medications being used.
Do not adjust a child’s dose without instructions from their healthcare provider.
Take Prezista every day according to your prescribed schedule.
Keeping a consistent amount of medication in your body helps control HIV and reduces the chance that the virus will become resistant to treatment.
If you miss a dose, follow the instructions provided by your healthcare provider or pharmacist.
In general, take the missed dose as soon as you remember if it is not too close to the next scheduled dose. If it is almost time for your next dose, skip the missed dose and continue with your regular schedule.
Do not take two doses at the same time to make up for a missed dose.
Do not stop taking Prezista, ritonavir or cobicistat, or your other HIV medications without speaking with your healthcare provider.
Skipping doses or stopping treatment may allow HIV to multiply, increase the amount of virus in your blood, and make the infection more difficult to treat.
Take Prezista exactly as prescribed and attend regular follow-up appointments.
Your healthcare provider may monitor your viral load, CD4 count, liver function, and other health measures to make sure your HIV treatment is working safely and effectively.
Prezista (Darunavir) is available in the following forms and strength:
Prezista can cause side effects, especially during the first few weeks or months of treatment.
Common side effects may include nausea, diarrhea, headache, or stomach discomfort. Tell your healthcare provider if these symptoms become severe or do not improve.
Prezista can affect the liver and, in rare cases, may cause serious liver injury.
Tell your healthcare provider if you have a history of liver disease, including hepatitis B or hepatitis C.
Your healthcare provider may recommend blood tests to monitor your liver function during treatment.
Seek medical attention if you develop symptoms such as yellowing of the skin or eyes, dark urine, severe tiredness, or persistent nausea.
Prezista is generally not recommended for people with severe liver impairment because there is limited information about its use in this group.
Your healthcare provider will determine whether Prezista is appropriate based on your liver function.
Tell your healthcare provider if you have severe kidney problems.
Darunavir itself is not mainly removed through the kidneys, but kidney function can still affect your overall HIV treatment plan, especially if you are taking other medications.
Prezista can interact with many medications.
Some interactions can increase side effects, reduce the effectiveness of your HIV treatment, or cause serious complications.
Tell your healthcare provider about all prescription medications, over-the-counter medicines, vitamins, supplements, and herbal products you take before starting Prezista.
Prezista can rarely cause a serious or life-threatening skin reaction.
Seek medical attention right away if you develop a severe rash, blistering, peeling skin, mouth sores, fever, or swelling of the face.
A rash may sometimes occur with other symptoms, so do not ignore a new or worsening skin reaction.
Do not take Prezista if you have had a serious allergic reaction to darunavir or any ingredient in the medication.
Seek emergency medical attention if you develop hives, difficulty breathing, or swelling of your face, lips, tongue, or throat.
Prezista may be used in certain children 3 years of age and older, depending on body weight, treatment history, and the specific HIV treatment plan.
Children should take Prezista only under the supervision of a healthcare provider.
Prezista is usually taken with a medication such as ritonavir or cobicistat to increase the amount of darunavir in the bloodstream.
These medications can also cause drug interactions, so your healthcare provider should review your full medication list before treatment begins.
Prezista helps control HIV, but it does not cure the infection.
Continue taking all of your HIV medications exactly as prescribed, even if you feel well or your viral load becomes very low.
Skipping doses or stopping treatment can allow HIV to multiply and may increase the risk of drug resistance.
Attend regular follow-up appointments while taking Prezista.
Your healthcare provider may monitor your viral load, CD4 count, liver function, and other health measures to make sure your treatment is working safely and effectively.
If you are pregnant, planning to become pregnant, or breastfeeding, talk to your healthcare provider before taking Prezista. Your provider can help determine whether Prezista is appropriate for you and whether any changes to your HIV treatment are needed. Do not start or stop HIV medication during pregnancy without medical advice.
No. Prezista should not be used by itself. It must be taken as part of a complete HIV treatment plan with other antiretroviral medications. Prezista is also usually taken with a booster such as ritonavir or cobicistat. Using several HIV medicines together helps control the virus more effectively and lowers the risk of drug resistance.
If you miss a dose, take it as soon as you remember, unless it is almost time for your next scheduled dose. If your next dose is approaching, skip the missed dose and continue with your regular schedule. Do not take two doses at the same time to make up for a missed dose. Because missed-dose instructions may depend on whether you take Prezista once or twice daily, ask your healthcare provider or pharmacist if you are unsure what to do.
HIV treatment is usually long-term. You may need to continue taking Prezista for as long as it remains effective, safe, and appropriate for your treatment plan. Your healthcare provider will monitor your viral load, CD4 count, treatment response, and any side effects to determine whether your HIV medications should be continued or changed. Do not stop Prezista or your other HIV medications without speaking with your healthcare provider.
