HYDROCHLOROTHIAZIDE+TELMISARTAN belongs to the class of anti-hypertensives primarily taken for the treatment of hypertension (high blood pressure). Hypertension or high blood pressure is a life-long or chronic condition in which the force exerted by the blood against the artery wall becomes too high. It can lead to the risk of heart diseases, like heart attack and stroke.

HYDROCHLOROTHIAZIDE+TELMISARTAN is a combination of Telmisartan (angiotensin II receptor antagonist) and Hydrochlorothiazide (thiazide diuretic or water pill). Telmisartan is an angiotensin receptor blocker that helps to relax and widen the blood vessels (arteries). Hydrochlorothiazide is a diuretic that prevents absorption of excess salt in the body, preventing fluid retention. Together it lowers blood pressure and prevents the risk of stroke, heart attack and oedema (fluid retention).

You can take HYDROCHLOROTHIAZIDE+TELMISARTAN with food or empty stomach. It should be swallowed whole with a glass of water. Your doctor will advise you how often you take your tablets based on your medical condition. In some cases, you may experience dizziness, feeling tired, nausea, diarrhoea, back pain, and cold/flu symptoms. Most of these side effects of HYDROCHLOROTHIAZIDE+TELMISARTAN do not require medical attention and gradually resolve over time. However, if the side effects are persistent, reach out to your doctor.

Do not use potassium supplements or its salt substitutes, unless the doctor has told you. In rare cases, HYDROCHLOROTHIAZIDE+TELMISARTAN can cause a condition that results in the skeletal muscle problem, leading to further to kidney failure. If you notice unexplained muscle pain, dark colour urine, tenderness, or weakness, especially if you also have a fever or unexplained tiredness, immediately contact the doctor. Do not use if you are pregnant, planning to get pregnant, stop taking HYDROCHLOROTHIAZIDE+TELMISARTAN and tell your doctor right away. Besides this, you should not use HYDROCHLOROTHIAZIDE+TELMISARTAN if you are unable to urinate. If you have diabetes, do not use HYDROCHLOROTHIAZIDE+TELMISARTAN with any medication that contains aliskiren (a blood pressure medicine). Before taking HYDROCHLOROTHIAZIDE+TELMISARTAN, tell your doctor if you have ever had liver disease, kidney failure, glaucoma, high or low levels of magnesium or potassium in your blood, have allergies or asthma, lupus (an autoimmune disease), diabetes, or an allergy to penicillin or sulfa drugs.

    Disease/Condition Glossary

    Hypertension: It is a chronic condition when blood pressure is too high. This condition can lead to hardened arteries (blood vessels), decreasing the blood and oxygen flow to the heart. Blood pressure is the measurement of the force that our heart uses to pump blood to all parts of the body. Raised blood pressure can cause chest pain (angina) and heart attack (when blood supply to the heart is blocked). Additionally, high blood pressure also causes brain damage (stroke) and kidney failure. High blood pressure can be diagnosed with the help of a blood pressure monitor or sphygmomanometer. Systolic pressure is the pressure when the heart pumps blood out. On the other hand, diastolic pressure is the pressure when your heart is at the resting stage between heartbeats. If your blood pressure is 140/90 mm of Hg, it means the systolic pressure is 140 mm of Hg and, diastolic pressure is 90 mm of Hg. Ideal blood pressure should be between 90/60 mm of Hg and 120/80 mm of Hg.
