Key takeaways
Alocril (nedocromil) and cromolyn are both prescription eye drops used to treat eye allergy symptoms, but they have some differences. Alocril (nedocromil) is typically used twice a day, while cromolyn needs to be used more frequently, about 4 to 6 times a day. Alocril is not a first-choice treatment and is often used when over-the-counter options don't work, whereas cromolyn is noted for its lower cost and is used for chronic eye allergies. Alocril can cause headaches and eye irritation, while cromolyn's common side effects are temporary stinging or burning. Both medications should not be used with contact lenses due to preservatives that can harm your eyes. Additionally, cromolyn is considered a good option for pregnant women, while Alocril does not have this specific mention.
