Ketotifeno Farmalider (Ketotifen Hydrogen Fumarate)

Ketotifen hydrogen fumarate blocks H1 histamine receptors on the conjunctival surface and stabilises mast cells, preventing the release of histamine and other inflammatory mediators. This dual action reduces both immediate and delayed allergic inflammation in the eye.

The dosing regimen for Ketotifeno Farmalider is determined by the prescribing clinician based on the severity of the allergic response and patient tolerance. Typically, one or two drops are instilled in the affected eye(s) as directed.

Safety data for ketotifen hydrogen fumarate in pregnancy and lactation are limited. The product should only be used if the potential benefit justifies any possible risk to the fetus or infant, and this decision should be made by a healthcare professional.

Ketotifeno Farmalider combines H1‑receptor antagonism with mast‑cell stabilisation, offering both rapid symptom relief and longer‑term control. Some alternatives provide only antihistamine activity, which may require more frequent dosing for comparable effect.

Store the ophthalmic solution at temperatures below 25 °C, in its original packaging, protected from moisture and direct sunlight. Do not freeze the product.

The product is applied topically to the eye. After washing hands, instil the prescribed number of drops into the conjunctival sac of the affected eye(s) and close the eyelids gently. Avoid touching the dropper tip to any surface.

Serious risks include severe allergic reactions such as angio‑edema of the eyelid, corneal ulceration, significant intra‑ocular pressure elevation, and rare cases of vision loss. Immediate medical attention is required if any of these occur.

Individuals with known hypersensitivity to ketotifen, its salts, or any formulation excipients should avoid using the product. It is also contraindicated in eyes that are actively infected or inflamed without physician supervision.
