Nervous system side effects associated with hydrochlorothiazide have included cerebrovascular insufficiency associated with HCTZ-induced plasma volume contraction. At least one case of cognitive and neurologic impairment (i.e., confusion, somnolence, feeling dazed) has been reported. Symptoms immediately resolved following discontinuation of hydrochlorothiazide.
Nervous system side effects associated with olmesartan have included dizziness (3% vs. 1% with placebo), vertigo (0.5% to 1% with placebo), and insomnia (0.5% to 1% with placebo). Asthenia has been reported in postmarketing experience.[Ref]
Cardiovascular side effects associated with amlodipine are dose-related, are usually the result of vasodilation, and include flushing in less than 1% and peripheral edema in 2% of patients. Peripheral edema may become a chronic problem, and has occurred in up to 10% of patients who are receiving 10 mg doses. Palpitations occur in 1% to 5% of patients. Recent data have shown that the use of amlodipine in patients with NYHA Class III or IV heart failure is not associated with worsened heart failure. Bradycardia, hypotension, and syncope have been reported in less than 1% of patients. Generalized edema has also been reported rarely.
Cardiac arrhythmias, including ventricular ectopy and complete AV heart block, are associated with hypokalemia and hyponatremia due to HCTZ. Hypotension has been reported in association with HCTZ-induced pulmonary edema. Orthostatic hypotension may occur and may rarely be associated with syncope, particularly in the elderly.
Cardiovascular side effects associated with olmesartan including tachycardia, chest pain, and peripheral edema have been reported in 0.5% to 1% of patients. At least 5 cases of facial edema and at least one case of olmesartan-induced angioedema, which resolved over 7 to 10 days after discontinuing olmesartan, have been reported.[Ref]
Dermatologic side effects including amlodipine-associated lichen planus and telangiectasia have been rarely reported.
Dermatologic side effects associated with HCTZ include case reports of erythema annular centrifugum, acute eczematous dermatitis, and morbilliform and leukocytoclastic vasculitis. Thiazides may induce phototoxic dermatitis. In addition, a rare, distinct entity with clinical and laboratory features indistinguishable from those of subacute cutaneous lupus erythematosus is associated with HCTZ.
Dermatologic side effects associated with olmesartan have included rash (0.5% to 1%), alopecia, pruritus, and urticaria.[Ref]

Metabolic side effects associated with hydrochlorothiazide are common, especially when doses greater than 50 mg per day are used. Mild hypokalemia (decrease of 0.5 mEq/L) occurs in up to 50% of patients, and may predispose patients to cardiac arrhythmias. Metabolic alkalosis, hyponatremia, hypomagnesemia, hypercalcemia, hyperglycemia, and elevated serum uric acid levels are also relatively common. Metabolic problems associated with thiazide diuretics also include glucose intolerance and a potentially deleterious effect on the lipid profile (i.e., increased serum cholesterol).
