•Timolol belongs to a group of medications called "beta blockers".

This medication reduces eye pressure in several ways.

Dorzolamida/Timolol Viatris is prescribed to reduce elevated eye pressure in the treatment of glaucoma when the use of a beta-blocker eye drop as monotherapy is not suitable.

No use Dorzolamida/Timolol Viatris:

• If you are allergic to dorzolamida, timolol or any of the other components of this medication (including those listed in section 6).
• If you currently have or have had respiratory problems, such as asthma or chronic obstructive pulmonary disease (COPD) severe (serious lung disease that can cause wheezing, difficulty breathing and/or long-term coughing).
• If you have a slow heart rate, heart failure or irregular heart rhythms.
• If you have severe kidney disease or a history of kidney stones.
• If you have excessive acidity in the blood as a result of a buildup of chloride in the blood (hyperchloremic acidosis).

Warnings and Precautions

• Coronary heart disease (symptoms may include chest tightness or pain, shortness of breath or asphyxia), heart failure or low blood pressure.
• Irregular heart rhythms, such as a slow heart rate.
• Respiratory problems, asthma or chronic obstructive pulmonary disease.
• Circulatory disorders, such as Raynaud's disease or syndrome.
