This medication is used to treat high blood pressure (hypertension). It is a combination of 2 drugs.
Amlodipine is in a group of drugs called calcium channel blockers. It works by relaxing the muscles of your heart and blood vessels.
Olmesartan is in a group of drugs called angiotensin II receptor antagonists. Olmesartan keeps blood vessels from narrowing, which lowers blood pressure and improves blood flow.

Take this medication exactly as it was prescribed for you. Do not take the medication in larger amounts, or take it for longer than recommended by your doctor. Follow the directions on your prescription label.

This medication is used to treat high blood pressure (hypertension). It is usually given after others have been tried without successful treatment of hypertension.

Store at room temperature away from moisture and heat.

You should not use this medication if you are allergic to amlodipine (Norvasc) or olmesartan (Benicar).
Before using this medication, tell your doctor if you are allergic to any drugs, or if you have:
kidney disease (or if you are on dialysis);
liver disease;
congestive heart failure;
if you are vomiting or having diarrhea;
if you have recently had a heart attack.
If you are also taking a beta-blocker drug (such as Blocadren, Corgard, Inderal, Normodyne, Tenormin, Toprol, Trandate, Zibeta, and others) do not suddenly stop using the beta-blocker without first talking to your doctor. You may need to use less and less before you stop the medication completely. Stopping a beta-blocker too quickly can cause serious heart problems that will not be prevented by this medication.
