Frequently Asked Questions for Optilast
Further Information
What is Optilast?
Optilast is a prescription eye drop containing azelastine hydrochloride, an antihistamine that helps reduce allergic symptoms in the eyes.
How It Works
Optilast works by blocking the release of histamine from mast cells in the eyes. Histamines are chemicals released during an allergic reaction that cause inflammation and irritation. By preventing histamine release, Optilast reduces the symptoms of watery, itchy, and red eyes.
Side Effects
Common side effects of Optilast may include temporary stinging or blurred vision after application. Some individuals might also experience a bitter taste in the mouth. These side effects typically subside shortly after use.
Warnings and Precautions
Before using Optilast, consult a doctor if:
- Your symptoms are limited to one eye.
- You have vision impairment or eye infections.
- Symptoms persist after 48 hours of use.
- You wear contact lenses—remove them before use and wait at least 15 minutes before reinserting.
For safe usage, follow the instructions on the packaging, and consult a healthcare provider if you have any concerns or experience unusual side effects.
