Compare Zaditor vs. Acular

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

Key takeaways

Zaditor (ketotifen) and ketorolac eye drops (Acular) are both eye drops, but they serve different purposes and have distinct characteristics. Zaditor is an over-the-counter antihistamine used to relieve itchy eyes caused by allergies. It’s typically used twice a day, is available as a lower-cost generic, and is safe for children aged 3 and older. Common side effects include headache and runny nose. On the other hand, ketorolac is a prescription-only, non-steroidal anti-inflammatory drug (NSAID) used to treat pain and inflammation after eye surgeries like cataract removal and corneal surgery. It can also help with allergy-related itchy eyes but is not the first choice for this condition. It’s used 2 to 4 times a day, and it can cause stinging or burning. Ketorolac eye drops are available in generic form and suitable for children as young as 2 years old. Both medications require you to remove contact lenses before use, but ketorolac eye drops have additional risks like slower healing and potential breathing problems for those with certain medical histories.
