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

Dorzolamida/Timolol Stulln contains two active substances: 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 pressure in the eye in different ways.

Dorzolamida/Timolol Stulln is prescribed to reduce high pressure in the eye in the treatment of glaucoma when the use of a single beta-blocker eye drop is not appropriate.

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

• if you have now or have had in the past respiratory problems, such as asthma or severe chronic obstructive pulmonary disease (severe lung disease that may cause wheezing, difficulty breathing and/or persistent cough over a long period of time).
• if you have a slow heart rate, heart failure or irregular heart rhythm (irregular heartbeats).
• if you suffer from severe kidney or urinary tract problems, or have a history of kidney stones.
