Dorsun Eye Drop

Dorsun Eye Drop is a prescription eye drop that contains dorzolamide, a carbonic anhydrase inhibitor used to lower high pressure inside the eye. Each drop contains dorzolamide as labelled on the pack from Sunways, India, and the product is supplied as a box of 10 eye drops. Dorsun Eye Drop is used to treat ocular hypertension and glaucoma, especially open-angle glaucoma, by helping reduce fluid pressure in the eye.

How it works: Dorzolamide works by blocking an enzyme in the eye that helps make aqueous humor, the fluid inside the eye. With less fluid produced, the pressure inside the eye can go down after Dorsun Eye Drop is placed in the eye.

Dorsun Eye Drop is a single-strength eye drop product, so there are no lower or higher sibling strengths listed for this brand. Because it is an eye drop rather than a tablet or capsule, it is meant to act locally in the eye with less whole-body exposure, and a doctor may choose it when ongoing pressure control is needed in a patient who can use topical therapy safely. This exact strength fits standard dorzolamide eye-drop use as directed by an eye doctor.

• Open-angle glaucoma
• Ocular hypertension
• Lowering elevated intraocular pressure
• Adjunct treatment in some glaucoma patients

• Wash your hands before using Dorsun Eye Drop.
• Tilt your head back, pull down the lower eyelid, and place the prescribed number of drops into the eye.
• Do not touch the dropper tip to your eye, fingers, or any surface.
• Close your eye gently for 1 to 2 minutes after instilling the drop.
• If you use other eye medicines, wait at least 5 to 10 minutes between products unless your doctor tells you otherwise.
• If you wear soft contact lenses, remove them before use and wait as advised by your prescriber before putting them back in.

Each dose of Dorsun Eye Drop provides dorzolamide as labelled on the pack, and the exact number of drops per dose is set by the prescriber. It is commonly used 3 times daily, but some patients may be told to use it twice daily depending on the treatment plan; do not use more often than prescribed. Your doctor decides the right schedule and maximum daily use for your eye pressure and overall eye-health status.

Do not change your dose or stop the medicine without speaking to your doctor.

Common side effects of Dorzolamide may include:

• Burning or stinging in the eye after instillation
• Blurred vision for a short time after use
• Bitter or unusual taste in the mouth
• Eye irritation or discomfort
• Eye redness
• Watery eyes

• Use Dorsun Eye Drop only in the eyes, not by mouth or injection.
• Tell your doctor if you have kidney disease, because dorzolamide may not be appropriate in severe kidney problems.
• Use caution if you have a sulfonamide allergy, since dorzolamide is related to sulfonamide medicines.
• Do not drive or operate machinery right after use if the drop causes blurred vision.
• Tell your doctor about asthma, COPD, or other breathing problems before starting treatment.
• Inform your clinician if you are pregnant or breastfeeding so the risk and benefit can be reviewed.
• Contact your doctor if eye pain, vision changes, or irritation gets worse instead of better.

• Other glaucoma eye drops, especially if used at the same time without spacing them out
• Oral carbonic anhydrase inhibitors such as acetazolamide or methazolamide
• High-dose aspirin or salicylate medicines
• Medicines that may affect kidney function
• Any product that irritates the eyes or changes how eye drops are absorbed

Store Dorsun Eye Drop at room temperature in the original box, tightly closed, and keep it away from excess heat, moisture, and direct light.
