Dorzolamide 2% eye drops is a carbonic anhydrase inhibitor medicine used to reduce high pressure in the eyes. It is useful for the following indications: 

1. Glaucoma (a condition where high eye pressure can damage the optic nerve) 
2. Ocular hypertension (high eye pressure that could lead to glaucoma) 
3. Prevent vision loss caused by high eye pressure 
4. Lower pressure in the eyes before or after certain eye surgeries (as prescribed by a doctor) 

1. Take this medicine exactly as prescribed by your doctor, at the same time each day. 
2. Do not stop taking this medicine without your doctor’s approval, even if you feel better. 
3. If you forget to take this medicine, take it as soon as you remember. If it’s almost time for your next dose, skip the missed dose.

2. Blurred vision temporarily after application 
3. Eye redness or irritation 
4. Unusual taste in the mouth (bitter or metallic)  

Less Common

1. Eye swelling or itching 
2. Tearing or watery eyes 
3. Headache 
4. Allergic reactions like rash or swelling around the eyes 

Dorzolamide works by reducing the amount of fluid (aqueous humor) in the eyes. In conditions like glaucoma or ocular hypertension, too much fluid builds up leading to increased eye pressure that can damage the optic nerve and affect the vision. Dorzolamide blocks an enzyme called carbonic anhydrase, which helps the eyes to produce this fluid. By lowering the fluid production, it reduces eye pressure, helps protect the optic nerve, and prevents vision loss.
