In monotherapy, the dose is one drop of dorzolamide in the conjunctival cul-de-sac of the affected eye (s), three times a day.

In combination with a beta-blocker for ophthalmic use, the dose is one drop of dorzolamide in the conjunctival cul-de-sac of the affected eye (s), twice daily.

If another antiglaucoma treatment is being replaced with dorzolamide, discontinue the other medication after the last dose of the day at the appropriate dose and start dorzolamide the next day.

Concomitant use of multiple eye drops should be administered at least 10 minutes apart.

Patients should be warned that contact should be avoided between the tip of the vial and the eye or surrounding areas.

Patients should also be informed that ophthalmic solutions, if improperly handled, may be contaminated by common bacteria known to cause eye infections. The use of contaminated solutions can cause severe serious injury and loss of vision.

Use in children:

In children, limited clinical data are available after administration of dorzolamide three times a day (for more information on the dosage in children see section 5.1 Pharmacodynamic properties ).

Against indications

Dorzolamide is contraindicated in patients with hypersensitivity to this active substance or to any of the excipients.

Dorzolamide has not been studied in patients with severe renal impairment (creatinine clearance <30 ml / min) or hyperchloremic acidosis.

Since dorzolamide and its metabolites are mainly excreted by the kidney, dorzolamide is therefore contraindicated in such patients.
