What Oftidorix is and what it is used for

Oftidorix is a combination of two medicines: dorzolamide and timolol.
• Dorzolamide belongs to a group of medicines called “carbonic anhydrase inhibitors”.
• Timolol belongs to a group of medicines called “beta blockers.
Oftidorix is prescribed to lower raised pressure within the eye in the treatment of glaucoma when betablocker eye drops used alone are not adequate.

medicine (listed in section 6),
if you have now or have had in past respiratory problems such as asthma, severe chronic obstructive
bronchitis (severe lung disease which may cause wheeziness, difficulty in breathing and/or longstanding cough),
if you have severe kidney problems, or a prior history of kidney stones,
if you have a disturbance in the pH (acid/alkali balance) of your blood,
if you have a slowheart beat, disorders of heart rhythm (irregular heart beats) or heart failure.

How to use Oftidorix

Always use this medicine exactly as your doctor or pharmacist has told you. Check with your doctor or
pharmacist if you are not sure.
The appropriate dosage and duration of treatment will be established by your doctor.
The recommended dose is one drop in the affected eye(s) two times a day, for example in the morning and in
the evening.
After using Oftidorix, press a finger into the corner of your eye, by the nose (picture 1) for 2 minutes. This
helps to stop active substance getting into the rest of the body.

If you use Oftidorix with another eye drop, leave at least 10 minutes between putting in Oftidorix and the
other medicine.
Do not change the dosage of the drug without consulting your doctor. If you must stop treatment, contact
your doctor immediately.
Do not allow the tip of the container to touch your eye or areas around your eye. It may become
contaminated with bacteria that can cause eye infections leading to serious damage of the eye, even loss of
vision. To avoid possible contamination of the container, keep the tip of the container away from contact
with any surface.
In order to secure correct dosage - the dropper tip should not be enlarged.
Instructions for use:
It is recommended that you wash your hands before putting in your eye drops.
