Major side effects include:



PREPARATIONS: Tablets: 5, 10, and 20 mg.

STORAGE: Timolol should be stored at room temperature, 15 C - 30 C (59 F - 86 F) and kept in a tightly sealed container protected from light

DOSING: The range of dosing for adults is 10 to 60 mg mg per day.

DRUG INTERACTIONS: The concurrent use of timolol and clonidine (Catapres), may cause rebound hypertension upon abrupt discontinuation of clonidine. It is advisable, therefore, to stop the beta adrenergic blocking drug by several days before gradually withdrawing clonidine. Fenoldopam (Corlopam), which is used for the treatment of severe hypertension should not be taken together with timolol as the combination may increase the risk of hypotension due to additive effects of the two drugs in lowering blood pressure.
