Compare Zaditor vs. Emadine

Head-to-head comparisons of medication uses, side effects, warnings, and more.

Key takeaways

Zaditor (ketotifen) and emadastine (Emadine) are both antihistamine eye drops used to treat allergy-related itchy eyes, but they have some key differences. Zaditor is available over the counter and can be used by adults and children aged 3 and older. It’s typically used twice a day, and it can cause side effects like headache, runny nose, and dry eyes. On the other hand, emadastine was a prescription-only eye drop that worked similarly to reduce inflammation and relieve red, itchy, and watery eyes. However, emadastine is no longer available in the U.S. because it was discontinued by the manufacturer for business reasons, not safety concerns.
