1. What is Dorzolamida/Timolol Vir and what is it used for

Dorzolamida/Timolol Vir is a combination of two medicines: dorzolamida and timolol.

• Dorzolamida belongs to a group of medicines called "carbonic anhydrase inhibitors".
• Timolol belongs to a group of medicines called "beta-blockers".

These medicines reduce eye pressure in different ways.

Dorzolamida/Timolol Vir is prescribed to reduce eye pressure in the treatment of glaucoma when the use of a beta-blocker eye drop alone is not adequate.

2. What you need to know before you use Dorzolamida/Timolol Vir

Do not use Dorzolamida/Timolol Vir

• if you are allergic to dorzolamida hydrochloride, timolol maleate or any of the other ingredients of this medicine (listed in section 6).
• if you have now or have had in the past respiratory problems such as asthma, severe chronic obstructive pulmonary disease (severe lung disease that may cause wheezing, difficulty breathing and/or prolonged coughing)
• if you have a slow heart rate, heart failure or heart rhythm disturbances (irregular heartbeats);
• if you suffer from severe kidney disease or a history of kidney stones.

• if you have excess acidity of the blood caused by an accumulation of chlorides in the blood (hyperchloremic acidosis).

Warnings and precautions

Consult your doctor or pharmacist before starting to use Dorzolamida/Timolol Vir.

Tell your doctor before you have surgery that you are using dorzolamida/timolol, as timolol may affect the effects of some medicines used during anesthesia.

Also, tell your doctor about any allergy or allergic reactions including hives, swelling of the face, lips, tongue and/or throat that may cause difficulty breathing or swallowing.

Tell your doctor if you have muscle weakness or if you have been diagnosed with severe myasthenia.
