discontinue hydrochlorothiazide as rapidly as possible if symptoms occur; prompt medical or surgical treatments may need to be considered if intraocular pressure remains uncontrolled; risk factors for developing acute angle-closure glaucoma may include history of sulfonamide or penicillin allergy Caution in patients with history of psychiatric illness; may cause or exacerbate CNS depression Beta-blockers can precipitate or aggravate symptoms of arterial insufficiency in patients with peripheral vascular disease There are no adequate and well-controlled studies in pregnant women Limited data on the use of metoprolol in pregnant women Risk to fetus/mother is unknown;
