Uses for amlodipine and valsartan
Amlodipine and valsartan is a combination of medicines that are used 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 heart failure or kidney failure. Lowering blood pressure reduces the risk of strokes and heart attacks.
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.
Valsartan 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, valsartan relaxes the blood vessels. This lowers blood pressure and increases the supply of blood and oxygen to the heart.
Amlodipine and valsartan is available only with your doctor's prescription.
Before using amlodipine and valsartan
In deciding to use a medicine, the risks of taking the medicine must be weighed against the good it will do. This is a decision you and your doctor will make. For amlodipine and valsartan, the following should be considered:
Tell your doctor if you have ever had any unusual or allergic reaction to amlodipine and valsartan or any other medicines. Also tell your health care professional if you have any other types of allergies, such as to foods, dyes, preservatives, or animals. For non-prescription products, read the label or package ingredients carefully.

Appropriate studies performed to date have not demonstrated geriatric-specific problems that would limit the usefulness of amlodipine and valsartan combination in the elderly. However, elderly patients may be more sensitive to the effects of amlodipine and valsartan than younger adults, which may require caution in patients receiving amlodipine and valsartan combination.

Proper use of amlodipine and valsartan
Amlodipine and valsartan combination is used when a single medicine to lower your blood pressure is not enough. It is also used as the first medicine to treat your condition if your doctor feels that you need to take more than one blood pressure medicine.
Amlodipine and valsartan comes with a patient information insert. Read and follow the instructions carefully. Ask your doctor if you have any questions.
In addition to the use of amlodipine and valsartan, treatment for your high blood pressure may include weight control and changes in the types of foods you eat, especially foods high in sodium (salt). Your doctor will tell you which of these are most important for you. You should check with your doctor before changing your diet.
Many patients who have high blood pressure will not notice any signs of the problem. In fact, many may feel normal. It is very important that you take your medicine exactly as directed and that you keep your appointments with your doctor even if you feel well.
Remember that amlodipine and valsartan will not cure your high blood pressure, but it does help control it. You must continue to take it as directed if you expect to lower your blood pressure and keep it down. You may have to take high blood pressure medicine for the rest of your life. 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 amlodipine and valsartan with or without food.

Precautions while using amlodipine and valsartan
It is very important that your doctor check your progress at regular visits to make sure amlodipine and valsartan is working properly. Blood and urine tests may be needed to check for unwanted effects.
Using amlodipine and valsartan while you are pregnant can harm your unborn baby. Use an effective form of birth control to keep from getting pregnant. If you think you have become pregnant while using the medicine, tell your doctor right away.
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 amlodipine and valsartan 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 amlodipine and valsartan, especially with severe or continuing nausea, vomiting, or diarrhea. These conditions may cause you to lose too much water or salt which may cause low blood pressure. You can also lose water by sweating, so drink plenty of water during exercise or in hot weather.
Amlodipine and valsartan may worsen the symptoms of angina (chest pain) or cause a heart attack in certain patients with severe heart or blood vessel disease. Check with your doctor right away if you are having chest pain or discomfort, fast or uneven heartbeat, nausea or vomiting, pain or discomfort in the arms, jaw, back, or neck, shortness of breath, or sweating.
Make sure any doctor or dentist who treats you knows that you are using amlodipine and valsartan. You may need to stop using amlodipine and valsartan several days before having surgery or medical tests.

Ask your doctor before you use any medicines, supplements, or salt substitutes that contain potassium.
Do not take other medicines unless they have been discussed with your doctor. This especially includes over-the-counter (nonprescription) medicines for appetite control, asthma, colds, cough, hay fever, or sinus problems, since they may tend to increase your blood pressure.
