Why is this medication prescribed?

Dorzolamide ophthalmic is a medication primarily prescribed to lower high pressure in the eye in patients with open-angle glaucoma or ocular hypertension. It belongs to a class of drugs called carbonic anhydrase inhibitors. By decreasing the production of fluid in the eye, dorzolamide helps to reduce intraocular pressure, thus preventing potential damage to the optic nerve and preserving vision.

How should this medicine be used?

As for how it should be used, typically it’s administered as eye drops. The usual dosage is one drop in the affected eye(s) three times a day. It’s important to follow the instructions provided by your healthcare provider precisely. If you have any questions about the proper administration or usage of dorzolamide ophthalmic, it’s best to consult with your doctor or pharmacist for clarification. Additionally, make sure to wash your hands before and after administering the drops, and avoid touching the dropper tip to any surface to prevent contamination.

Dorzolamide ophthalmic is typically used as eye drops. Here’s a general guide on how to use them:

  • Wash your hands thoroughly with soap and water before handling the eye drops.
  • Shake the bottle gently to ensure that the medication is well mixed.
  • Tilt your head back or lie down and look up.
  • With one hand, gently pull down the lower eyelid to create a small pocket.
  • Hold the dropper tip directly over the eye, being careful not to touch the tip to any surface.
  • With your other hand, squeeze the bottle to release one drop into the eye.
  • Close your eye gently and press your finger against the inner corner of your eye for about one to two minutes. This helps to prevent the medication from draining into your tear duct and being absorbed systemically.
  • If you need to administer drops to both eyes, repeat the process for the other eye.
  • Recap the bottle tightly.
  • Wash your hands again to remove any residual medication.

Remember to follow the specific instructions provided by your healthcare provider or pharmacist. If you have any questions or concerns about the proper use of dorzolamide ophthalmic, don’t hesitate to ask your healthcare provider for clarification.
