TELMICON-H TAB is a combination medication containing Telmisartan (40 mg) and Hydrochlorothiazide (12.5 mg). Telmisartan is an angiotensin II receptor blocker (ARB) that helps relax blood vessels, while Hydrochlorothiazide is a diuretic that aids in reducing excess fluid in the body. This combination is primarily used to treat high blood pressure (hypertension) and reduce the risk of stroke, heart attack, and kidney damage. It works by lowering blood pressure, thereby improving overall cardiovascular health. Common side effects include dizziness, fatigue, and low blood pressure, while less common effects may include electrolyte imbalance and dehydration. It is important to take the medication as prescribed by your doctor, avoid excessive salt intake, and stay hydrated. Always consult your healthcare provider before making any changes to your medication regimen.
