Tenoretic is used to treat essential hypertension (high blood pressure) in patients who need combination therapy to achieve adequate blood pressure control.
The medication combines two active ingredients: atenolol, a beta-blocker that reduces heart rate and the force of heart contractions, and chlorthalidone, a thiazide-like diuretic that helps the kidneys remove excess salt and water from the body, decreasing blood volume and blood pressure.
This medication may cause dizziness or fatigue; avoid alcohol and rising quickly from sitting or lying positions. Regular blood pressure monitoring and laboratory tests (electrolytes, kidney function) are important during treatment. Do not stop taking this medication abruptly without medical supervision.
