Patient leaflet - Olmesartan Medoxomil/amlodipine 20/5 mg film-coated tablets

1. What Olmesartan medoxomil/Amlodipine is and what it is used for

Olmesartan medoxomil/Amlodipine contains two substances called olmesartan medoxomil and amlodipine (as amlodipine besilate). Both of these substances help to control high blood pressure.

  • Olmesartan medoxomil belongs to a group of medicines called “angiotensin-II receptor antagonists” which lower blood pressure by relaxing the blood vessels.
  • Amlodipine belongs to a group of substances called “calcium channel blockers”. Amlodipine stops calcium from moving into the blood vessel wall which stops the blood vessels from tightening thereby also reducing blood pressure.

The actions of both these substances contribute to stopping the tightening of blood vessels, so that blood vessels relax and blood pressure decreases.

Olmesartan medoxomil/Amlodipine is used for the treatment of high blood pressure in patients whose blood pressure is not controlled enough with either olmesartan medoxomil or amlodipine alone.

2. What you need to know before you take Olmesartan medoxomil/Amlodipine

Do not take Olmesartan medoxomil/Amlodipine:

  • if you are allergic to olmesartan medoxomil or to amlodipine or a special group of calcium channel blockers, the dihydropyridines or to any of the other ingredients of this medicine (listed in section 6).

    if you think you may be allergic, talk to your doctor before taking Olmesartan medoxomil/Amlodipine.

  • if you are more than 3 months pregnant (It is also better to avoid Olmesartan medoxomil/Amlodipine in early pregnancy - see section “Pregnancy and breastfeeding”.).
  • if you have diabetes or impaired kidney function and you are treated with a blood pressure lowering medicine containing aliskiren.
  • if you have severe liver problems, if bile secretion is impaired or drainage of bile from the gallbladder is blocked (e.g. by gallstones), or if you are experiencing any jaundice (yellowing of the skin and eyes).
  • if you have very low blood pressure.
  • if you are suffering from insufficient blood supply to your tissues with symptoms like e.g. low blood pressure, low pulse, fast heartbeat (shock, including cardiogenic shock). Cardiogenic shock means shock due to severe heart troubles.
  • if the blood flow from your heart is obstructed (e.g. because of the narrowing of the aorta (aortic stenosis)).
  • if you suffer from low heart output (resulting in shortness of breath or peripheral swellings) after a heart attack (acute myocardial infarction).

Warnings and precautions

Talk to your doctor or pharmacist before taking Olmesartan medoxomil/Amlodipine.

Tell your doctor if you are taking any of the following medicines used to treat high blood pressure:

  • an ACE-inhibitor (for example enalapril, lisinopril, ramipril), in particular if you have diabetes-related kidney problems,
  • aliskiren.

Talk to your doctor if you experience abdominal pain, nausea, vomiting or diarrhoea after taking Olmesartan medoxomil/Amlodipine. Your doctor will decide on further treatment. Do not stop taking Olmesartan medoxomil/Amlodipine on your own.

Your doctor may check your kidney function, blood pressure, and the amount of electrolytes (e.g. potassium) in your blood at regular intervals.

See also information under the heading “Do not take Olmesartan medoxomil/Amlodipine”.

Tell your doctor if you have any of the following health problems:

  • Kidney problems or a kidney transplant.
  • Liver disease.
  • Heart failure or problems with your heart valves or heart muscle.
  • Severe vomiting, diarrhoea, treatment with high doses of “water tablets” (diuretics) or if you are on a low salt diet.
  • Increased levels of potassium in your blood.
  • Problems with your adrenal glands (hormone-producing glands on top of the kidneys).

Contact your doctor if you experience diarrhoea that is severe, persistent and causes substantial weight loss. Your doctor may evaluate your symptoms and decide on how to continue your blood pressure medication.

As with any medicine which reduces blood pressure, an excessive drop in blood pressure in patients with blood flow disturbances of the heart or brain could lead to a heart attack or stroke. Your doctor will therefore check your blood pressure carefully.

You must tell your doctor if you think that you are (or might become) pregnant. Olmesartan medoxomil/Amlodipine is not recommended in early pregnancy, and must not be taken if you are more than 3 months pregnant, as it may cause serious harm to your baby if used at that stage (see section “Pregnancy and breast-feeding”).

Children and adolescents (under 18)

Olmesartan medoxomil/Amlodipine is not recommended for children and adolescents under the age of 18.

Other medicines and Olmesartan medoxomil/Amlodipine

Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines.

  • Other blood pressure lowering medicines, as the effect of Olmesartan medoxomil/Amlodipine can be increased. Your doctor may need to change your dose and/or to take other precautions:

    If you are taking an ACE-inhibitor or aliskiren (see also information under the headings “Do not take Olmesartan medoxomil/Amlodipine” and “Warnings and precautions”).

  • Potassium supplements, salt substitutes containing potassium, “water tablets” (diuretics) or heparin (for thinning the blood and prevention of blood clots.). Using these medicines at the same time as Olmesartan medoxomil/Amlodipine may raise the levels of potassium in your blood.
  • Lithium (a medicine used to treat mood swings and some types of depression) used at the same time as Olmesartan medoxomil/Amlodipine may increase the toxicity of lithium. If you have to take lithium, your doctor will measure your lithium blood levels.
  • Non-Steroidal Anti-Inflammatory Drugs (NSAIDs, medicines used to relieve pain, swelling and other symptoms of inflammation, including arthritis) used at the same time as Olmesartan medoxomil/Amlodipine may increase the risk of kidney failure. The effect of Olmesartan medoxomil/Amlodipine can be decreased by NSAIDs.
  • Colesevelam hydrochloride, a drug that lowers the level of cholesterol in your blood, as the effect of Olmesartan medoxomil/Amlodipine may be decreased. Your doctor may advise you to take Olmesartan medoxomil/Amlodipine at least 4 hours before colesevelam hydrochloride.
  • Certain antacids (indigestion or heartburn remedies), as the effect of Olmesartan medoxomil/Amlodipine can be slightly decreased.
  • Medicines used for HIV/AIDS (e.g. ritonavir, indinavir, nelfinavir) or for the treatment of fungal infections (e.g. ketoconazole, itraconazole).
  • Diltiazem, verapamil, (agents used for heart rhythm problems and high blood pressure).
  • Rifampicin, erythromycin, clarithromycin (antibiotics) agents used for tuberculosis or other infections
  • St. John’s wort (Hypericum perforatum), a herbal remedy.
  • Dantrolene (infusion for severe body temperature abnormalities).
  • Simvastatine, an agent used to lower levels of cholesterol and fats (triglycerides) in the blood.
  • Tacrolimus, cyclosporine, used to control your body’s immune response, enabling your body to accept the transplanted organ

Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines.

Olmesartan medoxomil/Amlodipine with food and drink

Olmesartan medoxomil/Amlodipine can be taken with or without food. Swallow the tablet with some fluid (such as one glass of water). If possible, take your daily dose at the same time each day, for example at breakfast time.

Grapefruit juice and grapefruit should not be consumed by people who are taking Olmesartan medoxomil/Amlodipine. This is because grapefruit and grapefruit juice can lead to an increase in the blood levels of the active ingredient amlodipine, which can cause an unpredictable increase in the blood pressure lowering effect of Olmesartan medoxomil/Amlodipine.

Elderly

If you are over 65 years of age, your doctor will regularly check your blood pressure at any dose increase, to make sure that your blood pressure does not become too low.

Black patients

As with other similar drugs the blood pressure lowering effect of Olmesartan medoxomil/Amlodipine can be somewhat less in black patients.

Pregnancy and breast-feeding

Pregnancy

You must tell your doctor if you think that you are (or might become) pregnant. Your doctor will normally advise you to stop taking Olmesartan medoxomil/Amlodipine before you become pregnant or as soon as you know you are pregnant and will advise you to take another medicine instead of Olmesartan medoxomil/Amlodipine. Olmesartan medoxomil/Amlodipine is not recommended in early pregnancy, and must not be taken when more than 3 months pregnant, as it may cause serious harm to your baby if used after the third month of pregnancy.

If you become pregnant during therapy with Olmesartan medoxomil/Amlodipine, please inform and see your physician without delay.

Breast-feeding

Tell your doctor if you are breast-feeding or about to start breast-feeding. Amlodipine has been shown to pass into breast milk in small amounts. Olmesartan medoxomil/Amlodipine is not recommended for mothers who are breast-feeding, and your doctor may choose another treatment for you if you wish to breast-feed, especially if your baby is newborn, or was born prematurely.

If you are pregnant or breast-feeding, think you may be pregnant or are planning to have a baby, ask your doctor or pharmacist for advice before taking this medicine.

Driving and using machines

You may feel sleepy, sick or dizzy or get a headache while being treated for your high blood pressure. If this happens, do not drive or use machines until the symptoms wear off. Ask your doctor for advice.

Olmesartan medoxomil/Amlodipine contains lactose monohydrate

This medicine contains lactose (a type of sugar). If you have been told by your doctor that you have an intolerance to some sugars, contact your doctor before taking this medicine.

3. How to take Olmesartan medoxomil/Amlodipine
