Description
Levamlodipine is used alone or together with other medicines to lower hypertension (high blood pressure) in adults and children. 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.
Levamlodipine is a calcium channel blocker. It affects the movement of calcium into the cells of the heart and blood vessels. This relaxes the blood vessels and lowers blood pressure. A lower blood pressure will increase the supply of blood and oxygen to the heart.
This medicine is available only with your doctor's prescription.
This product is available in the following dosage forms:
- Tablet

Precautions
It is very important that your doctor check your or your child's progress at regular visits to make sure this medicine is working properly. Blood tests may be needed to check for unwanted effects.
This medicine may cause angina (chest pain) or 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 irregular heartbeat, nausea or vomiting, pain or discomfort in the arms, jaw, back, or neck, trouble breathing, or sweating.
Dizziness, lightheadedness, or fainting may also occur, especially when you get up suddenly from a lying or sitting position. 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. If you faint, call your doctor right away.
Dizziness, lightheadedness, or fainting may also occur if you exercise or if the weather is hot. Heavy sweating can cause loss of too much water and result in low blood pressure. Use extra care during exercise or hot weather.
Check with your doctor right away if you or your child have pain or tenderness in the upper stomach, pale stools, dark urine, loss of appetite, nausea, vomiting, or yellow eyes or skin. These could be symptoms of a serious liver problem.
If you have been using this medicine regularly for several weeks, do not suddenly stop using it. Stopping suddenly may cause your chest pain or high blood pressure to come back or get worse. Check with your doctor for the best way to reduce gradually the amount you are taking before stopping completely.
Do not take other medicines unless they have been discussed with your doctor. This especially includes prescription or nonprescription (over-the-counter [OTC]) medicines for appetite control, asthma, colds, cough, hay fever, or sinus problems, and herbal or vitamin supplements.
