Description
Indications
Ketotifen is indicated for the prevention and treatment of ocular itching associated with allergies, such as seasonal and allergic conjunctivitis. This ophthalmic medication targets the histamine receptor to mitigate allergic symptoms. Ketotifen also acts as a mast cell stabilizer, inhibiting the release of natural mediators responsible for allergic responses.
Uses and Dosage
Ketotifen for ophthalmic use is a liquid solution that is administered by instillation into the eye(s). Typically, the recommended dosing frequency is twice daily, with a dosing interval of 8 to 12 hours between administrations.
To ensure optimal therapeutic outcomes, instill the eye drops at consistent times daily. Any deviation from the recommended dosage, such as using more or less medication or dosing more frequently than prescribed, is strongly discouraged.
To administer the eye drops, the following steps should be followed:
- Thoroughly wash hands with soap and water.
- Do not allow the dropper tip to touch the eye or any other surface, and ensure that it is kept clean.
- Tilt the head back and pull down the lower lid of the eye using the index finger to form a pocket.
- Hold the dropper as close to the eye as possible without making contact, and brace the remaining fingers against the face.
- Squeeze the dropper gently to instill a single drop in the pocket created by the lower eyelid while looking upwards.
- Remove the index finger from the lower eyelid and keep the eye closed for 2-3 minutes while tilting the head down.
- Apply gentle pressure to the tear duct using a finger.
- Use a tissue to wipe off any excess liquid from the face.
- Wash hands to remove any residual medication.
