Micardis (Telmisartan): Uses, Dosage & Side Effects

Micardis is the brand name for telmisartan, a drug prescribed to treat high blood pressure and congestive heart failure. Micardis Plus is also available, containing both telmisartan and the diuretic hydrochlorothiazide.

Type

• Micardis is classified as an angiotensin II receptor antagonist, which blocks the effects of a hormone called angiotensin II. Angiotensin II tends to constrict blood vessels and promote retention of fluid and salt.

Dosage

• Patients are usually advised to take Micardis once a day with or without food. They usually begin with 40 mg and increase dosage to 80 mg, if necessary.

Common Side Effects

• Common side effects associated with Micardis use include back pain, diarrhea, respiratory tract or sinus infection, runny nose and sore throat.

Pregnancy Considerations

• Micardis can cause severe birth defects and even be fatal to an unborn baby if a pregnant woman takes this medication during the second and third trimesters.

Caution

• Micardis also can cause blood pressure to drop too low, particularly in congestive heart failure patients whose blood pressure was normal. This is more common with Micardis Plus.
