Description
What is Telmisartan 40 mg?
Telmisartan 40 mg is an oral prescription medication that belongs to a class of drugs called angiotensin II receptor blockers (ARBs). It is primarily used to treat high blood pressure (hypertension) and helps prevent complications like stroke, heart attack, and kidney damage.
Telmisartan works by blocking angiotensin II, a chemical that tightens blood vessels, thereby allowing blood vessels to relax and widen, leading to lowered blood pressure and improved blood flow.
How to Use Telmisartan 40 mg
-
Dosage: The standard starting dose for adults is 40 mg once daily. Depending on blood pressure control, a doctor may increase or adjust the dose up to 80 mg daily.
-
Administration: Take the tablet by mouth, with or without food, preferably at the same time each day.
-
Missed Dose: If a dose is missed, take it as soon as you remember. If it’s close to the next dose, skip the missed one—do not double the dose.
-
