What is triprolidine?
Triprolidine is an antihistamine that reduces the effects of natural chemical histamine in the body. Histamine can produce symptoms of sneezing, itching, watery eyes, and runny nose.
Triprolidine is used to treat sneezing, runny nose, watery eyes, hives, skin rash, itching, and other cold or allergy symptoms.
Triprolidine may also be used for purposes not listed in this medication guide.
What are the possible side effects of triprolidine?

How should I take triprolidine?
Use exactly as directed on the label, or as prescribed by your doctor. Do not use in larger or smaller amounts or for longer than recommended. Cough or cold medicine is usually taken only for a short time until your symptoms clear up.
Do not give this medicine to a child younger than 4 years old. Always ask a doctor before giving a cough or cold medicine to a child. Death can occur from the misuse of cough and cold medicines in very young children.

What happens if I miss a dose?
Since triprolidine is used when needed, you may not be on a dosing schedule. If you are on a schedule, use the missed dose as soon as you remember. Skip the missed dose if it is almost time for your next scheduled dose. Do not use extra medicine to make up the missed dose.

Drinking alcohol can increase certain side effects of triprolidine.
Ask a doctor or pharmacist before using any other cold, cough, allergy, or sleep medicine. Many combination medicines contain antihistamines. Taking certain products together can cause you to get too much of this type of medicine.
Avoid becoming overheated or dehydrated during exercise and in hot weather. Triprolidine can decrease sweating and you may be more prone to heat stroke.
