Istalol is a prescription medication that is commonly used to treat high eye pressure in patients with open-angle glaucoma or ocular hypertension. It belongs to a class of drugs known as beta-blockers, which work by reducing the production of fluid in the eye, thereby lowering intraocular pressure.

This medication is typically administered as eye drops and should be used exactly as prescribed by your healthcare provider. It is important to follow the dosing instructions carefully and not to exceed the recommended dosage. Istalol is usually applied once daily in the affected eye(s), preferably in the evening.

Before using Istalol, it is important to inform your healthcare provider about any medical conditions you may have, especially if you have a history of heart problems, asthma, or certain other eye conditions. Additionally, let your doctor know about any other medications or supplements you are currently taking, as they may interact with Istalol.

While Istalol is generally well-tolerated, some common side effects may include eye irritation, blurred vision, or a bitter taste in the mouth. If you experience any severe or persistent side effects, it is important to contact your healthcare provider immediately.

Overall, Istalol can be an effective treatment option for managing high eye pressure and reducing the risk of vision loss associated with glaucoma. By following your doctor’s instructions and attending regular eye exams, you can help ensure the best possible outcomes while using this medication.
