Can timolol cause shortness of breath and tiredness?
Patient: I have just started to take timolol for eye pressure. It has been about 4 weeks. On my runs, I have noticed some shortness of breath and feeling there is something with my leg muscles (unusual tiredness). Can the use of timolol be causing these systems? Doctor: Hi,  Suggestive of timolol-induced side effects. Timolol is a beta-adrenergic blocker commonly prescribed in the form of eye drops to reduce intraocular pressure in patients suffering from glaucoma.  Although it is used locally in the eyes, some amount of the drug gets absorbed into systemic circulation (blood) producing unwanted side effects as you seem to have developed following its use.  Ask your doctor for an alternate effective but a safer medication for the treatment of glaucoma.     Hope I have answered your query. Let me know if I can assist you further.  Take care  Regards, Dr. Mohammad Taher Ali
