Manual :

1. Before first use, check that the tamper evident ring at the neck of the vial is not broken. The presence of a space between the stopper and the unopened vial is normal;

2. Remove the cap from the vial.

3. Tilt the head back and gently pull the lower eyelid down to instil drops between the eyelid and the eye.

4. Invert the bottle and squeeze gently between your thumb and forefinger until only one drop falls into the eye as directed by your doctor. Do not touch the eye or eyelid with the tip of the vial.

5. Repeat steps 2 and 3 for the other eye if your doctor has prescribed it.

6. Replace the cap and close the bottle immediately after use.

In children:

In children, limited clinical data are available after administration of dorzolamide three times daily (for further information see section 5.1 ).

Against indications

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.
