Recommended Usage Frequency for Ketotifen Eye Drops
For adults and children aged 3 years and older seeking relief from the eye itchiness associated with allergies, following the recommended usage instructions for ketotifen eye drops is key to managing symptoms effectively. The specific frequency of use is outlined in the product's labeling and should be strictly adhered to. Using the eye drops more often than recommended is not advised.
How Ketotifen Provides Relief
Ketotifen is an ophthalmic medication that offers temporary relief from allergic eye symptoms through a dual mechanism. It acts as a mast cell stabilizer, which helps to prevent the release of histamine and other inflammatory mediators from mast cells in response to allergens. Additionally, it functions as an antihistamine by blocking histamine H1-receptors. This action helps to reduce symptoms like itching, redness, and swelling in the eyes caused by histamine. This combined effect provides relatively fast relief that can last for a period of time, supporting a specific usage schedule for sustained symptom management.
