The following additional adverse effects have been reported in clinical experience with the drug: cerebral ischemia, cerebral vascular accident, gout, muscle cramps, oculogyric crisis, worsening of chronic obstructive pulmonary disease, earache, and impotence.

Other adverse reactions that have been reported with the individual components are listed below:

Timolol Maleate _ Body as a Whole: extremity pain, decreased exercise tolerance, weight loss, fever; Cardiovascular: cardiac arrest, cerebral vascular accident, worsening of angina pectoris, sinoatrial block, AV block, worsening of arterial insufficiency, Raynaud†s phenomenon, claudication, palpitations, vasodilatation, cold hands and feet, edema; Digestive: hepatomegaly, elevated liver function tests, vomiting; Hematologic: nonthrombocytopenic purpura; Endocrine: hyperglycemia, hypoglycemia; Skin: skin irritation, pruritus, sweating, alopecia; Musculoskeletal: arthralgia; Nervous System: local weakness, vertigo, paresthesia, increase in signs and symptoms of myasthenia gravis; Psychiatric: depression, nightmares, hallucinations; Respiratory: cough; Special Senses: visual disturbances, diplopia, ptosis, eye irritation, dry eyes, tinnitus; Urogenital: urination difficulties.
