How Telmisartan 40mg and Chlorthalidone 12.5mg Works
Telmisartan belongs to a class of drugs called angiotensin II receptor blockers (ARBs). It works by relaxing blood vessels, allowing blood to flow more easily and reducing blood pressure. Chlorthalidone is a thiazide-like diuretic (water pill) that helps your kidneys remove excess salt and water from the body, which also lowers blood pressure. Together, they provide a dual mechanism to control hypertension.
Common Side Effects of Telmisartan 40mg and Chlorthalidone 12.5mg
- Dizziness or lightheadedness, especially when standing up quickly
- Increased urination (due to the diuretic effect)
- Headache
- Fatigue
- Low potassium levels (hypokalemia) – symptoms may include muscle cramps, weakness, or irregular heartbeat
- Increased blood sugar levels
- Dry mouth or increased thirst
Most side effects are mild and temporary. However, if you experience severe dizziness, fainting, rapid or irregular heartbeat, or signs of an allergic reaction (rash, itching, swelling), seek medical attention immediately.
