About Olmesartan 5 mg + Hydrochlorothiazide 12.5 mg

Olmesartan 5 mg + Hydrochlorothiazide 12.5 mg tablet is mainly used to lower high blood pressure and reduce swelling. Doctors prescribe it for kidney stones and to normalize blood pressure. It works by reducing the pressure on heart and helping the body flush out extra salt and water, which eases pressure on blood vessels. Common side effects include frequent urination, dizziness, headache, tiredness, nausea, constipation, low potassium, sensitivity to sunlight, gout, and higher blood sugar. Alcohol, painkillers like NSAIDs, and lithium can interfere with its effect, while a low-salt diet or potassium supplements may be advised. Extra care is needed in older adults and people with diabetes, gout, or liver and kidney problems. Taking too more than 40 mg can be dangerous, causing severe dehydration, very low blood pressure, salt imbalance, and irregular heartbeat that require urgent medical care.
