    Description

    Amlodipine is used alone or together with other medicines to treat hypertension (high blood pressure). 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. High blood pressure may also increase the risk of heart attacks. These problems may be less likely to occur if blood pressure is controlled.

    Amlodipine is also used to relieve chronic stable angina (chest pain) or vasospastic angina (Prinzmetal's or variant angina). This medicine is also used to lower the risk of hospitalization for angina and heart surgery (eg, coronary revascularization) in patients with recently documented coronary artery disease (CAD) by angiography and without certain heart problems (eg, heart failure or an ejection fraction less than 40%).

    Amlodipine is a calcium channel blocker. It works by affecting the movement of calcium into the cells of the heart and blood vessels. This relaxes the blood vessels and lowers blood pressure, 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:

    • Solution
    • Suspension
    • Tablet

    Before Using

    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 this medicine, the following should be considered:

    Allergies

    Tell your doctor if you have ever had any unusual or allergic reaction to this medicine 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.

    Pediatric

    Appropriate studies have not been performed on the relationship of age to the effects of amlodipine to lower blood pressure in children younger than 6 years of age or to relieve chest pain in children. Safety and efficacy have not been established.

    Geriatric

    Appropriate studies performed to date have not demonstrated geriatric-specific problems that would limit the usefulness of amlodipine in the elderly. However, elderly patients are more likely to have age-related kidney, liver, or heart problems, which may require caution and an adjustment in the dose for patients receiving this medicine.

    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 worsening of 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.

    After taking a dose of this medicine you may get a headache that lasts for a short time. This should become less noticeable after you have taken this medicine for a while. If this effect continues, or if the headaches are severe, check with your doctor.

    In some patients, tenderness, swelling, or bleeding of the gums may appear soon after treatment with this medicine is started. Brushing and flossing your teeth carefully and regularly and massaging your gums may help prevent this. See your dentist regularly to have your teeth cleaned. Check with your doctor or dentist if you have any questions about how to take care of your teeth and gums, or if you notice any tenderness, swelling, or bleeding of your gums.

    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.
