Amlodipine and olmesartan

Name: Amlodipine and olmesartan

What should I discuss with my healthcare provider before taking amlodipine and olmesartan?

You should not use this medicine if you are allergic to amlodipine (Norvasc) or olmesartan (Benicar).

If you have diabetes, do not use amlodipine and olmesartan together with any medication that contains aliskiren (such as Amturnide, Tekturna, Tekamlo).

You may also need to avoid taking amlodipine and olmesartan with aliskiren if you have kidney disease.

To make sure amlodipine and olmesartan is safe for you, tell your doctor if you have:

  • kidney disease;

  • liver disease;

  • coronary artery disease;

  • angina (chest pain), congestive heart failure;

  • high levels of potassium in your blood;

  • if you are on a low-salt diet;

  • if you are 75 years or older; or

  • if you recently had a heart attack.

Do not use if you are pregnant. If you become pregnant, stop taking this medicine and tell your doctor right away. Amlodipine and olmesartan can cause injury or death to the unborn baby if you take the medicine during your second or third trimester.

It is not known whether amlodipine and olmesartan passes into breast milk or if it could harm a nursing baby. You should not breast-feed while using this medicine.

Amlodipine and olmesartan is not approved for use by anyone younger than 18 years old.

Amlodipine and olmesartan side effects

Get emergency medical help if you have signs of an allergic reaction: hives; difficulty breathing; swelling of your face, lips, tongue, or throat.

In rare cases, when you first start taking this medicine, you may have new or worsening chest pain (angina), or you could have a heart attack. Seek emergency medical attention or call your doctor right away if you have symptoms such as: chest pain or pressure, pain spreading to your jaw or shoulder, nausea, sweating.

Call your doctor at once if you have:

  • new or worsening chest pain;

  • severe or ongoing diarrhea with weight loss;

  • pounding heartbeats or fluttering in your chest;

  • a light-headed feeling, like you might pass out;

  • swelling in your hands or feet, rapid weight gain;

  • jaundice (yellowing of the skin or eyes); or

  • high potassium--nausea, slow or unusual heart rate, weakness, loss of movement.

Common side effects include:

  • dizziness, drowsiness;

  • swelling;

  • skin rash or itching;

  • flushing (warmth, redness, or tingly feeling); or

  • increased urination (especially at night).

This is not a complete list of side effects and others may occur. Call your doctor for medical advice about side effects. You may report side effects to FDA at 1-800-FDA-1088.

What are some side effects that I need to call my doctor about right away?

WARNING/CAUTION: Even though it may be rare, some people may have very bad and sometimes deadly side effects when taking a drug. Tell your doctor or get medical help right away if you have any of the following signs or symptoms that may be related to a very bad side effect:

  • Signs of an allergic reaction, like rash; hives; itching; red, swollen, blistered, or peeling skin with or without fever; wheezing; tightness in the chest or throat; trouble breathing or talking; unusual hoarseness; or swelling of the mouth, face, lips, tongue, or throat.

Pharmacology

Amlodipine: Directly acts on vascular smooth muscle to produce peripheral arterial vasodilation reducing peripheral vascular resistance and blood pressure.

Olmesartan: Blocks the vasoconstrictor and aldosterone-secreting effects of angiotensin II.

Dosing Geriatric

Refer to adult dosing. Initial therapy is not recommended in patients ≥75 years.

Patient Education

• Discuss specific use of drug and side effects with patient as it relates to treatment. (HCAHPS: During this hospital stay, were you given any medicine that you had not taken before? Before giving you any new medicine, how often did hospital staff tell you what the medicine was for? How often did hospital staff describe possible side effects in a way you could understand?)

• Patient may experience flushing or headache. Have patient report immediately to prescriber signs of kidney problems (urinary retention, hematuria, change in amount of urine passed, or weight gain), signs of high potassium (abnormal heartbeat, confusion, dizziness, passing out, weakness, shortness of breath, numbness or tingling feeling), severe dizziness, passing out, angina, shortness of breath, excessive weight gain or loss, swelling of arms or legs, muscle rigidity, tremors, abnormal movements, or severe diarrhea (HCAHPS).

• Educate patient about signs of a significant reaction (eg, wheezing; chest tightness; fever; itching; bad cough; blue skin color; seizures; or swelling of face, lips, tongue, or throat). Note: This is not a comprehensive list of all side effects. Patient should consult prescriber for additional questions.

Intended Use and Disclaimer: Should not be printed and given to patients. This information is intended to serve as a concise initial reference for health care professionals to use when discussing medications with a patient. You must ultimately rely on your own discretion, experience, and judgment in diagnosing, treating, and advising patients.
