[Posted 04/20/2012]ISSUE:FDA notified healthcare professionals of possible risks when using blood pressure medicines containing aliskiren with other drugs called angiotensin converting enzyme inhibitors (ACEIs) and angiotensin receptor blockers (ARBs) in patients with diabetes or kidney (renal) impairment. These drug combinations should not be used (are contraindicated) in patients with diabetes. In addition, avoid use of aliskiren with ARBs or ACEIs in patients with moderate to severe renal impairment (i.e., where glomerular filtration rate [GFR] < 60 mL/min). The labels for the aliskiren drugs are being updated based on preliminary data from a clinical trial, ''Aliskiren Trial in Type 2 Diabetes Using Cardio-Renal Endpoints (ALTITUDE).''
BACKGROUND:Aliskiren is a renin inhibitor used to treat high blood pressure (hypertension) by lowering blood pressure.
RECOMMENDATION:Concomitant use of aliskiren with ARBs or ACEIs in patients with diabetes is contraindicated because of the risk of renal impairment, hypotension, and hyperkalemia. Avoid use of aliskiren with ARBs or ACEIs in patients with renal impairment where GFR < 60 mL/min. Patients should not stop taking aliskiren without talking to your healthcare professional. Stopping aliskiren suddenly can cause problems if your high blood pressure (hypertension) is not treated.
See the Drug Safety Communication for the Data Summary at: Web Sitefor a list of ACEI and ARB products, and additional recommendations for healthcare professionals and patients. For more information visit the FDA website at: Web Siteand Web Site.
Amlodipine is used alone or in combination with other medications to treat high blood pressure and chest pain (angina). Amlodipine is in a class of medications called calcium channel blockers. It lowers blood pressure by relaxing the blood vessels so the heart does not have to pump as hard. It controls chest pain by increasing the supply of blood to the heart. If taken regularly, amlodipine controls chest pain, but it does not stop chest pain once it starts. Your doctor may prescribe a different medication to take when you have chest pain.
Amlodipine comes as a tablet to take by mouth. It is usually taken once a day. To help you remember to take amlodipine, take it around the same time every day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take amlodipine exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.
Your doctor will probably start you on a low dose of amlodipine and gradually increase your dose.
Amlodipine controls high blood pressure and chest pain (angina) but does not cure them. Continue to take amlodipine even if you feel well. Do not stop taking amlodipine without talking to your doctor.
This medication may be prescribed for other uses; ask your doctor or pharmacist for more information.
Before taking amlodipine,
- tell your doctor and pharmacist if you are allergic to amlodipine or any other medications.
- tell your doctor and pharmacist what prescription and nonprescription medications, vitamins, nutritional supplements, and herbal products you are taking.
- tell your doctor if you have or have ever had heart failure or liver disease.
- tell your doctor if you are pregnant, plan to become pregnant, or are breast-feeding. If you become pregnant while taking amlodipine, call your doctor.
If your doctor prescribes a low-salt or low-sodium diet, follow these directions carefully.
Take the missed dose as soon as you remember it. However, if it is almost time for the next dose, skip the missed dose and continue your regular dosing schedule. Do not take a double dose to make up for a missed one.
Amlodipine may cause side effects. Tell your doctor if any of these symptoms are severe or do not go away:
- swelling of the hands, feet, ankles, or lower legs
- upset stomach
- stomach pain
- dizziness or lightheadedness
- excessive tiredness
- flushing (feeling of warmth)
Some side effects can be serious. The following symptoms are uncommon, but if you experience any of them, call your doctor immediately:
- more frequent or more severe chest pain
- rapid, pounding, or irregular heartbeat
If you experience a serious side effect, you or your doctor may send a report to the Food and Drug Administration's (FDA) MedWatch Adverse Event Reporting program online [at Web Site] or by phone [1-800-332-1088].

Keep all appointments with your doctor. Your blood pressure should be checked regularly to determine your response to amlodipine.
Do not let anyone else take your medication. Ask your pharmacist any questions you have about refilling your prescription.
It is important for you to keep a written list of all of the prescription and nonprescription (over-the-counter) medicines you are taking, as well as any products such as vitamins, minerals, or other dietary supplements.
