This medication relieves seasonal and year-round allergy symptoms such as watery/itchy eyes, runny nose, and sneezing. It is also used to relieve itching and hives caused by some skin conditions. Cyproheptadine belongs to a class of drugs known as antihistamines. It works by blocking the action of certain natural substances in the body (histamine and serotonin). Do not use this medication in children younger than 2 years unless specifically directed by the doctor. To decrease the risk for serious side effects, carefully follow all of the doctor's dosage directions. Do not give other cough and cold medication that might contain the same or similar ingredients (see also Drug Interactions section). Ask your doctor or pharmacist about other ways to relieve cough and cold symptoms (e.g., saline nose drops/spray, using a humidifier or infant nasal suction bulb).
If you miss a dose, use it as soon as you remember. If it is near the time of the next dose, skip the missed dose and resume your usual dosing schedule. Do not double the dose to catch up.
