The most commonly reported side effects of telmisartan/hydrochlorothiazide include upper respiratory infection, dizziness, sinus infection, and diarrhea. Rare side effects include sore throat, back pain, or increased heart rate. While most telmisartan/hydrochlorothiazide side effects do not require medical attention, notify your healthcare provider immediately if you experience serious problems, such as weak or irregular heartbeat, unexplained skin rash, or seizures.
As with any medicine, there are possible side effects of telmisartan/hydrochlorothiazide (Micardis HCT®). However, not everyone who takes the medicine will experience side effects. In fact, most people tolerate telmisartan/hydrochlorothiazide quite well. If side effects do develop, in many cases, they are minor, meaning they require no treatment or are easily treated by you or a healthcare provider. Serious side effects can occur, but are less common.
(This article covers many, but not all, of the possible side effects with telmisartan/hydrochlorothiazide. Your healthcare provider can discuss a more complete list of side effects with you.)
