What is Ketotifen?

  • Ketotifen is an antihistamine that works by reducing the effects of the body's natural chemical histamine. Sneezing, scratching, watery eyes, and a runny nose are all signs of histamine. Ketotifen ophthalmic (for use in the eyes) relieves scratching caused by allergies to dust, pollen, poultry, or other allergens. Ketotifen is an asthma drug that can be taken every day and in combination with other antiasthma drugs. It can help children with asthma attacks or symptoms by reducing the frequency, severity, and length of their attacks. It can also reduce the need for other antiasthma drugs on a regular basis. It is ineffective in both preventing and treating acute asthma attacks.
