Cyproheptadine: Frequently Asked Questions Answered

What is cyproheptadine?

Cyproheptadine is an antihistamine drug that eases allergic symptoms like runny nose, watery eyes, redness, itchiness, irritation, sneezing, etc. When you consume it, it blocks histamine, a natural substance your body produces in response to an allergic reaction. Moreover, it also helps treat hives, including those caused by cold temperatures or rubbing of the skin.

Doctors use cyproheptadine to treat several allergic reactions accompanied by bleeding, and certain life-threatening allergies and their symptoms.

What are the uses of cyproheptadine?

During an allergic reaction, your immune system produces histamine to destroy the allergen. In this process, histamine makes you sneeze, itch, tear up, etc. This is part of your body’s natural defense to fight abnormal activity. 

Doctors prescribe antihistamines to tame these allergic symptoms. The uses of cyproheptadine include reducing:

  • Sneezing 
  • Itchy, blocked, or runny nose
