Why is this medication prescribed?

Betagan, also known by its generic name levobunolol, is a medication primarily prescribed to treat high pressure inside the eye due to glaucoma or other eye conditions (e.g., ocular hypertension). It belongs to a class of drugs called beta blockers, which work by reducing the production of fluid in the eye, thereby lowering intraocular pressure.

How should this medicine be used?

Here’s how Betagan is typically used:

  • Dosage: The dosage of Betagan can vary depending on the severity of the condition and individual response to the medication. Your doctor will prescribe the appropriate dosage for you.
  • Administration: Betagan is usually applied directly into the affected eye(s) as eye drops.
  • Frequency: The typical frequency of Betagan administration is usually one drop in the affected eye(s) twice daily, although your doctor may adjust this based on your response to treatment.
  • Proper Application: When using Betagan eye drops, follow these steps:
    • Wash your hands thoroughly before handling the medication.
    • Tilt your head back slightly and pull down your lower eyelid to create a small pocket.
    • Hold the dropper directly over the eye and place one drop into the pouch.
    • Close your eyes gently for 1-2 minutes to allow the medication to spread evenly over the eye.
    • If you are using drops in both eyes, repeat the process for the other eye.
    • Avoid touching the tip of the dropper to any surface to prevent contamination.
  • Consistency: It’s important to use Betagan regularly and as prescribed by your doctor for the best results. Missing doses may reduce the effectiveness of the medication.
  • Duration: Continue using Betagan for as long as prescribed by your doctor, even if you feel well. Stopping the medication abruptly can cause your eye condition to worsen.
  • Monitoring: Your eye pressure may need to be monitored regularly by your doctor while using Betagan to ensure that the medication is effectively controlling your condition.

Always follow your doctor’s instructions and advice regarding the use of Betagan or any other medication. If you have any questions or concerns about your treatment, be sure to discuss them with your healthcare provider.

Some medications may interact with Betagan, potentially affecting its effectiveness or increasing the risk of side effects.
