Head-to-head comparisons of medication uses, side effects, warnings, and more.
Key takeaways
Emedastine (Emadine) and nedocromil (Alocril) are both eye drops used to treat allergy-related symptoms like itchy and watery eyes. However, they belong to different medication classes. Emedastine is an antihistamine, while nedocromil is a mast cell stabilizer. Emedastine was discontinued in the U.S. for business reasons and is no longer available, whereas nedocromil is still available by prescription. Nedocromil side effects include headaches and eye irritation. Nedocromil is typically used twice daily and is not a first-choice treatment, often reserved for persistent allergies not relieved by over-the-counter options. Additionally, nedocromil should not be used with contact lenses due to potential irritation.
