Descriptions


Telmisartan and amlodipine is a combination of medicines that may be used alone or with other medicines to treat high blood pressure (hypertension). High blood pressure adds to the workload of the heart and arteries. If it continues for a long time, the heart and arteries may not function properly. This can damage the blood vessels of the brain, heart, and kidneys, resulting in a stroke, heart failure, or kidney failure. Lowering blood pressure can reduce the risk of strokes and heart attacks.

Telmisartan is an angiotensin II receptor blocker (ARB). It works by blocking a substance in the body that causes blood vessels to tighten. As a result, the blood vessels relax and this decreases blood pressure. When blood pressure is lowered, the amount of blood and oxygen that go to the heart is increased.

Amlodipine is a calcium channel blocker (CCB). It affects the movement of calcium into the cells of the heart and blood vessels. As a result, amlodipine relaxes the blood vessels and increases the supply of blood and oxygen to the heart while reducing its workload.

This medicine is available only with your doctor's prescription.

This product is available in the following dosage forms:

  • Tablet

Proper Use

This medicine comes with a patient information insert. Read and follow the instructions carefully. Ask your doctor if you have any questions.

If high blood pressure is not treated, it can cause serious problems such as heart failure, blood vessel disease, stroke, or kidney disease.

You may take this medicine with or without food.

Dizziness, lightheadedness, or fainting may also occur, especially when you get up from a lying or sitting position or if you have been taking a diuretic (water pill). Make sure you know how you react to this medicine before you drive, use machines, or do anything else that could be dangerous if you are dizzy or not alert. If you feel dizzy, lie down so you do not faint. Then sit for a few moments before standing to prevent the dizziness from returning.

Check with your doctor right away if you become sick while taking this medicine, especially with severe or continuing nausea, vomiting, or diarrhea. These conditions may cause you to lose too much water and may lead to low blood pressure. You can also lose water by sweating, so drink plenty of water during exercise or in hot weather.

Hyperkalemia (high potassium in the blood) may occur in certain people receiving this medicine. Check with your doctor right away if you have the following symptoms: abdominal or stomach pain, confusion, difficulty with breathing, irregular heartbeat, nausea or vomiting, nervousness, numbness or tingling in the hands, feet, or lips, shortness of breath, or weakness or heaviness of the legs. Ask your doctor before you use medicines, supplements, or salt substitutes that contain potassium.

This medicine may worsen the symptoms of angina (chest pain) or increase risk of heart attack in certain patients with severe heart or blood vessel disease. Check with your doctor right away if you have chest pain that is worse than usual, trouble breathing, nausea or vomiting, pain or discomfort in your arms, jaw, back, or neck, feel faint, or you are sweating.

Do not take other medicines unless they have been discussed with your doctor. This especially includes nonprescription medicines for appetite control, asthma, colds, cough, hay fever, or sinus problems, since they may increase your blood pressure.
