Ketotifen: Uses, Dosage, Side Effects and More

Introduction: What is Ketotifen?

Ketotifen is a medication primarily used to manage allergic conditions and asthma. It belongs to a class of drugs known as antihistamines and mast cell stabilizers. By blocking the action of histamine, a substance in the body that causes allergic symptoms, Ketotifen helps alleviate symptoms such as sneezing, itching, and runny nose. It is also effective in preventing asthma attacks by stabilizing mast cells, which release inflammatory substances during allergic reactions.

Uses of Ketotifen

Ketotifen is approved for several medical uses, including:

1. Allergic Rhinitis: It helps relieve symptoms associated with hay fever and other allergies.
2. Asthma: Ketotifen is used as a preventive treatment for asthma, particularly in children.
3. Conjunctivitis: It can be used to treat allergic conjunctivitis, reducing eye symptoms like redness and itching.
4. Urticaria: Ketotifen is effective in managing chronic hives and other skin allergies.

How It Works

Ketotifen works by blocking histamine receptors in the body, which helps reduce allergic reactions. It also stabilizes mast cells, preventing them from releasing histamine and other inflammatory substances. In simpler terms, think of Ketotifen as a shield that protects your body from the effects of allergens, helping to keep symptoms at bay.

The dosage of Ketotifen varies based on age and the condition being treated:
