Usage

 

What is Ketotifen fumarate?


Ketotifen hydrogen fumarate is an antihistamine and mast cell stabilizer medication. It's primarily used to manage allergic conditions such as allergic conjunctivitis (itchy, watery eyes due to allergies) and asthma.

 

Its functions include:

 

Antihistamine: Ketotifen works by blocking the effects of histamine, a substance produced by the body during an allergic reaction. By inhibiting histamine, it helps alleviate symptoms like itching, redness, and swelling.

 

Mast Cell Stabilization: It also stabilizes mast cells, which are involved in allergic reactions. Mast cells release histamine and other inflammatory substances when triggered by allergens. Ketotifen helps prevent these cells from releasing these substances, reducing the severity of allergic reactions.

 

Ketotifen is available in various forms, including eye drops for allergic conjunctivitis and oral preparations for asthma and other systemic allergic conditions. As with any medication, it's essential to use Ketotifen as prescribed by a healthcare professional to achieve the best results and minimize potential side effects.
