For Healthcare Professionals
Applies to timolol ophthalmic: ophthalmic gel forming solution, ophthalmic solution
Topically applied timolol ophthalmic (the active ingredient contained in Timoptic Ocudose) drops may be absorbed systemically and side effects similar to systemically administered timolol or other beta-blockers such as severe respiratory or cardiac reactions may be experienced.
In clinical trials, timolol ophthalmic solution and gel forming solution had a similar incidence of side effects.
The results of a comparative trial suggest that timolol maleate may be more irritating than timolol hemihydrate.
Blurred vision upon instillation lasting from 30 seconds to 5 minutes has been reported in 33% of patients receiving the sustained release gel forming solution.
Ocular side effects have included burning and stinging upon instillation, which has been reported in approximately 12% of patients receiving timolol ophthalmic drops. Signs of ocular irritation including but not limited to conjunctivitis, blepharitis, keratitis, ocular pain, discharge/crusting, foreign body sensation, itching, tearing, and dry eyes. Ptosis, decreased corneal sensitivity, cystoid macular edema, visual disturbances (including refractive changes and diplopia), pseudopemphigoid, impairment of tear production and turnover, and choroidal detachment following filtration surgery have also been reported. In addition, cases of bacterial keratitis have been reported as a result of inadvertent contamination by patients.
Cardiovascular side effects have included bradycardia, arrhythmia, hypotension, hypertension, syncope, heart block, cerebral vascular accident, cerebral ischemia, exacerbation of angina, palpitation, cardiac arrest, pulmonary edema, edema, claudication, Raynaud's phenomenon, and cold hands and feet. It should be noted that death due to cardiac failure has been reported following use of ophthalmic timolol.
Cardiovascular side effects associated with oral timolol or other oral beta-blockers have included worsening of arterial insufficiency and vasodilatation.
Respiratory side effects have included respiratory failure, dyspnea, nasal congestion, cough, and upper respiratory infections. It should be noted that death due to bronchospasm, in patients with asthma, has been reported following use of ophthalmic timolol.
Respiratory side effects associated with timolol, as with other beta-antagonists, have included bronchial constriction in susceptible patients. Alternative therapy should be considered in patients with reactive airways disease.
Respiratory side effects associated with oral timolol or other oral beta-blockers have included rales and bronchial obstruction.
A case of refractory rhinitis is reported. The rhinitis may have been due to timolol-induced vasomotor changes.
The results of one study show that in otherwise healthy patients with glaucoma, long-term (3 yrs) treatment with ophthalmic timolol 0.5% can result in a significant reduction from baseline in FEV1 and a subclinical increase in bronchial reactivity which may not be completely reversible upon discontinuation of therapy.
Alternative therapy should be considered in patients with diabetes mellitus who are prone to hypoglycemia.
Endocrinologic side effects have included masking the signs and symptoms and blunting the normal physiologic response to hypoglycemia.
Endocrinologic side effects associated with timolol have included an increase in serum triglycerides, LDL cholesterol, and VLDL cholesterol, a decrease in HDL cholesterol, hyperglycemia, and hypoglycemia.
A case of amaurosis fugax is associated with timolol. However, the patient involved had underlying cerebrovascular disease, autonomic dysfunction, and an arrhythmia.
Nervous system side effects have included dizziness, headache, paresthesia, anxiety, somnolence, insomnia, nightmares, nervousness, memory loss, and disorientation. Timolol may worsen myasthenia gravis.
Nervous system side effects associated with oral timolol or other oral beta-blockers have included vertigo, local weakness, diminished concentration, an acute reversible syndrome characterized by disorientation for time and place, and slightly clouded sensorium.
Sexual dysfunction is reported from questionnaires, although the questions may have biased the data since the responses were not spontaneous.
