1. What is Dorzolamidum + Timololum Stulln and what is it used for

Dorzolamidum + Timololum Stulln contains two active substances: dorzolamide and timolol.

• Dorzolamide belongs to a group of medicines called "carbonic anhydrase inhibitors".
• Timolol belongs to a group of medicines called "beta-adrenergic receptor blockers" (beta-adrenolytics). These medicines lower intraocular pressure through two different mechanisms.

Dorzolamidum + Timololum Stulln is recommended for the treatment of glaucoma to lower elevated intraocular pressure, when the use of eye drops containing only a beta-adrenergic receptor blocker is not sufficient.

2. Important information before using Dorzolamidum + Timololum Stulln

When not to use Dorzolamidum + Timololum Stulln:

• if the patient is allergic to dorzolamide hydrochloride, timolol maleate, or any of the other ingredients of this medicine (listed in section 6);
• if the patient currently has or has had respiratory disorders, such as asthma or severe chronic obstructive pulmonary disease (a serious lung disease that can cause wheezing, breathing difficulties, and/or a persistent cough);
• if the patient has a slow heart rate, heart failure, or irregular heart rhythm;
• if the patient has severe kidney disease or severe kidney function disorders, or a history of kidney stones;
• if the patient has hyperchloremic acidosis (excessive acidification of the blood due to the accumulation of chloride ions in the body).

In case of doubts about whether to use this medicine, consult a doctor or pharmacist.
