Periactin contains the active ingredient cyproheptadine. It is a prescription antihistamine that your healthcare provider may prescribe to manage certain allergic conditions. In some cases, it may also be prescribed for other purposes, such as improving appetite or preventing migraines.
Periactin can help relieve symptoms that occur when your body reacts to an allergen, such as pollen, dust, animal dander, certain foods, or other substances. These symptoms may include:
Periactin may be used to manage seasonal allergies, such as hay fever, as well as allergies that occur throughout the year. It may also help treat allergic conjunctivitis, which causes red, watery, or itchy eyes.
Periactin may be prescribed to relieve chronic urticaria, commonly known as hives. Hives appear as raised, red, or skin-coloured welts that may be very itchy. The welts may appear suddenly, disappear, and then develop in a different area.
The medication may also help manage other mild allergic skin reactions, including itching and swelling. It reduces the effects of histamine, which is one of the substances responsible for these symptoms.
Cyproheptadine can increase appetite in some people. For this reason, a healthcare provider may prescribe Periactin to someone who has difficulty eating enough, has a reduced appetite, or needs support gaining weight.
Appetite stimulation is not one of the main allergy-related uses listed in the medication’s official prescribing information. Your healthcare provider will consider your health, nutritional needs, and the possible benefits and risks before prescribing it for this purpose.
Periactin may sometimes be prescribed to help prevent migraines or certain other recurring headaches. It affects serotonin as well as histamine, which may help reduce the frequency of headaches in some patients.
This is generally considered an off-label use, meaning that a healthcare provider may prescribe the medication based on their clinical judgment even though migraine prevention is not included among its primary approved uses.
During an allergic reaction, your body releases a natural chemical called histamine. Histamine can cause symptoms such as itching, sneezing, a runny nose, watery eyes, swelling, and hives.
Periactin blocks histamine from attaching to certain receptors in your body. This helps reduce allergy symptoms and makes allergic reactions more manageable.
Periactin is known as a first-generation antihistamine. Medications in this group can enter the brain and may cause sleepiness, dizziness, or reduced alertness. Avoid driving or operating machinery until you know how the medication affects you.
Take Periactin only as directed by your healthcare provider. The reason for taking it, the dose, and the length of treatment may differ from one patient to another.
Cyproheptadine is available as a tablet that you take by mouth. You may take it with or without food. However, if the medication causes an upset stomach, taking it with food may make it easier to tolerate.
Take cyproheptadine exactly as directed by your healthcare provider. It is commonly taken two to three times a day, although the number of doses may differ depending on why you are taking it. Try to take each dose at approximately the same time every day to help maintain a consistent amount of medication in your body.
Your healthcare provider will determine the right dose for you. The dose may depend on:
Children usually receive a lower dose than adults. A child’s dose may be calculated according to age, body weight, or body surface area. Never give cyproheptadine to a child unless a healthcare provider has recommended it and provided clear dosing instructions.
When cyproheptadine is used to relieve allergy symptoms, adults may be prescribed a total daily dose of 4 mg to 20 mg. This amount is usually divided into two to four smaller doses throughout the day.
The exact dose will depend on the type and severity of the allergic reaction. Your healthcare provider may begin with a lower dose and adjust it based on how well your symptoms improve and whether you experience side effects.
Children may be prescribed a smaller amount based on their age and weight. Do not use the adult dosage for a child.
Cyproheptadine may sometimes be prescribed to improve appetite or support weight gain in people who have difficulty eating enough. This may include people with certain illnesses, poor nutritional intake, or unintended weight loss.
When used for appetite stimulation, an adult may be prescribed 2 mg to 4 mg up to three times a day. However, the dose can vary significantly from one person to another. Your healthcare provider will decide whether this use is appropriate and may monitor your appetite, weight, nutrition, and possible side effects during treatment.
Using cyproheptadine for appetite stimulation may be considered an off-label use in some regions. This means a healthcare provider may prescribe it based on clinical judgment even though appetite stimulation may not be listed as an officially approved use on the local product label.
Swallow the tablet with water. Do not take more than the prescribed amount, take doses closer together, or continue treatment longer than recommended. Taking too much cyproheptadine can increase the risk of serious side effects.
If you miss a dose, take it when you remember. However, if it is nearly time for your next scheduled 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.
Cyproheptadine can cause drowsiness, dizziness, blurred vision, or reduced alertness. These effects may be more noticeable when you first begin treatment or after your dose is increased. Avoid driving, operating machinery, or performing tasks that require concentration until you know how the medication affects you.
Alcohol, sleep medications, sedatives, opioid pain medications, and other medicines that cause drowsiness may increase these effects. Speak with your healthcare provider or pharmacist before combining cyproheptadine with these substances.
Do not change your dose or stop taking cyproheptadine without speaking with your healthcare provider. Contact your healthcare provider or pharmacist if you are unsure how much to take, when to take it, or how long your treatment should continue.
Periactin (Cyproheptadine) is available in the following forms and strengths:
Before taking Periactin, tell your healthcare provider about your medical history, allergies, pregnancy status, and any other medications or supplements you use. This information helps your healthcare provider decide whether cyproheptadine is suitable for you.
Speak with your healthcare provider before taking cyproheptadine if you are pregnant, think you may be pregnant, or are planning to become pregnant.
Available information about cyproheptadine use during pregnancy is limited. Animal studies have not shown harm to the fetus when the medication was taken by mouth at recommended doses, and limited human studies have not identified an increased risk of birth defects. However, the available evidence cannot completely rule out possible risks.
Your healthcare provider will consider the expected benefits of treatment and any potential risks before prescribing cyproheptadine during pregnancy. Use it only when your healthcare provider determines that it is clearly needed.
Tell your healthcare provider if you are breastfeeding or planning to breastfeed. Cyproheptadine may not be appropriate during breastfeeding because first-generation antihistamines may affect a nursing infant. The medication may also reduce alertness in the baby or potentially affect milk production.
Do not take cyproheptadine while breastfeeding unless your healthcare provider specifically advises you to do so. Some cyproheptadine product labels list breastfeeding as a contraindication.
Do not take cyproheptadine if you have previously had an allergic reaction to it or to a medication with a similar chemical structure.
Before beginning treatment, tell your healthcare provider or pharmacist about all medication, food, dye, preservative, or other allergies you have. Cyproheptadine tablets and liquids may contain inactive ingredients, such as lactose, flavouring agents, colouring agents, or preservatives. These ingredients can cause allergic reactions or other problems in some people. The exact ingredients may differ between products and manufacturers.
Seek immediate medical attention if you develop signs of a serious allergic reaction, such as:
Older adults may be more sensitive to the effects of cyproheptadine. The medication has sedating and anticholinergic effects, which means it can affect alertness, balance, vision, digestion, urination, and memory.
Possible effects in older adults may include:
Cyproheptadine is listed in the American Geriatrics Society Beers Criteria as a first-generation antihistamine that is potentially inappropriate for many adults aged 65 and older. This does not mean that every older adult can never take it. However, healthcare providers generally avoid it when safer alternatives are available because the risks may be greater in this age group.
An older adult should not stop taking prescribed cyproheptadine without first speaking with a healthcare provider. The healthcare provider can review the medication, consider safer options, and determine whether continued treatment is appropriate.
Cyproheptadine commonly causes drowsiness because it can enter the brain and slow activity in the central nervous system. You may also experience dizziness, blurred vision, poor coordination, or difficulty concentrating.
Do not drive, operate machinery, or perform tasks that require alertness until you know how the medication affects you. Alcohol, sleeping pills, opioid pain medications, anxiety medications, muscle relaxants, and other sedating medicines can increase these effects. Ask your healthcare provider or pharmacist before combining cyproheptadine with any medication or substance that causes drowsiness.
Cyproheptadine can cause side effects, although not everyone experiences them. Common or possible effects may include:
This is not a complete list of possible side effects. Contact your healthcare provider if a side effect becomes severe, does not improve, or interferes with your normal activities.
Seek medical attention promptly if you experience fainting, severe confusion, a seizure, hallucinations, difficulty urinating, a very fast or irregular heartbeat, severe vision changes, or signs of a serious allergic reaction. Reported antihistamine reactions include sedation, dizziness, confusion, restlessness, coordination problems, and, less commonly, seizures or hallucinations.
Cyproheptadine may be prescribed to children when a healthcare provider determines that it is appropriate. The dose must be based on the child’s age, weight, condition, and response to treatment.
Safety and effectiveness have not been established in children younger than two years. Cyproheptadine should not be used in newborn or premature infants. Never give this medication to a young child without specific instructions from a healthcare provider.
Children may become sleepy after taking cyproheptadine. However, some children may have the opposite reaction and become unusually restless, excited, irritable, or unable to sleep. Monitor the child closely when treatment begins or when the dose changes.
Give only the prescribed dose. An overdose of an antihistamine can be particularly dangerous in children and may cause extreme sleepiness, agitation, hallucinations, seizures, breathing problems, or loss of consciousness. Store the medication securely and out of the sight and reach of children.
Cyproheptadine blocks the effects of serotonin, a natural chemical that can play a role in reducing appetite. By blocking certain serotonin receptors, cyproheptadine may increase feelings of hunger and help some people eat more. Increased appetite and weight gain are also known effects of the medication. However, cyproheptadine should only be used for appetite stimulation when recommended by a healthcare provider. Your healthcare provider may monitor your appetite, weight, nutrition, and possible side effects during treatment. Cyproheptadine also blocks histamine and has sedating and anticholinergic effects.
Cyproheptadine is not normally prescribed as a standard treatment for anxiety or insomnia. It is primarily an antihistamine used to relieve allergy symptoms. It may also be prescribed for other purposes, such as appetite stimulation, based on a healthcare provider’s clinical judgment. Cyproheptadine commonly causes drowsiness, but this does not mean that it is an appropriate sleep medication. Using it only to help you sleep may expose you to side effects such as dizziness, dry mouth, blurred vision, constipation, confusion, and difficulty urinating. Do not use cyproheptadine for anxiety or sleep problems unless your healthcare provider specifically recommends it.
Cyproheptadine may begin relieving allergy symptoms within a few hours after you take a dose. However, the exact time can vary depending on the condition being treated, the dose, and your individual response. Effects such as improved appetite or weight gain usually take longer to notice and may develop gradually over several days or weeks. Speak with your healthcare provider if your symptoms do not improve or if you are unsure how long the medication should take to work.
Cyproheptadine is not a general treatment for an upset stomach, indigestion, or abdominal pain. However, healthcare providers sometimes prescribe it off-label for certain functional digestive disorders, particularly in children. Studies have suggested that it may help some children with conditions such as functional abdominal pain, functional dyspepsia, abdominal migraine, cyclic vomiting syndrome, or irritable bowel syndrome. However, much of the available evidence comes from retrospective studies rather than large, well-controlled clinical trials. Results from one study should not be interpreted as proof that the medication will work for every patient. Do not take cyproheptadine for stomach symptoms unless your healthcare provider has identified the cause of your symptoms and recommended the medication. Persistent or severe abdominal pain, repeated vomiting, blood in the stool, unexplained weight loss, or difficulty eating requires medical assessment.
