Information about Ketotifen

Ketotifen is typically used to manage and prevent symptoms associated with allergies.

Ketotifen works by blocking histamine receptors in the body, which helps to reduce allergic reactions.

Histamine is a chemical in the body that causes symptoms like itching, swelling, and redness during an allergic response.

By preventing histamine from binding to its receptors, Ketotifen helps to alleviate these symptoms.

Not everyone will experience side effects, and many are mild and temporary.

If you experience serious or persistent symptoms, contact your doctor.
