1. What is Karbis and what is it used for

The name of the medicine is Karbis. The active substance is candesartan cilexetil. It belongs to a group of medicines called angiotensin II receptor antagonists. It works by relaxing and widening the blood vessels. This makes it easier to get the blood to all the parts of your body.

This medicine is used for:

  • Treatment of high blood pressure (hypertension) in adult and children and adolescents aged 6 to 18 years.
  • Karbis can be used for the treatment of heart failure in adult patients with reduced kidney function when ACE inhibitors are not suitable, or added to ACE inhibitors when symptoms persist despite treatment and mineralocorticoid receptor antagonists (MRAs) cannot be used (ACE inhibitors and MRAs are medicines used for the treatment of heart failure).

2. What you need to know before you take Karbis

Do not take Karbis

  • if you are allergic to candesartan cilexetil or any of the other ingredients of this medicine (listed in section 6),
  • if you are more than 3 months pregnant. (In any case, it is better to avoid taking Karbis also at the start of your pregnancy – see section Pregnancy),
  • if you have severe liver disease or biliary obstruction (problem with the release of bile from the gallbladder),
  • if the patient is a child under 1 year of age,
  • if you have diabetes or kidney impairment and are being treated with a medicine containing aliskiren.

If you are not sure if any of these apply to you, talk to your doctor or pharmacist before taking Karbis.

Warnings and precautions

Talk to your doctor or pharmacist before taking Karbis:

  • if you have heart, liver or kidney problems, or are undergoing dialysis,
  • if you have recently had a kidney transplant,
  • if you have vomiting, have recently had severe vomiting or have diarrhea,
  • if you have an adrenal gland problem called Conn’s syndrome (also known as primary hyperaldosteronism),
  • if you have low blood pressure,
  • if you have ever had a stroke,
  • if you are pregnant (or if you plan to become pregnant) you must inform your doctor. It is not recommended to use Karbis at the start of pregnancy and it should not be taken after the third month of pregnancy as it may harm your baby (see section Pregnancy).
  • if you are taking any of the following medicines used to treat high blood pressure:
  • an ACE inhibitor (e.g. enalapril, lisinopril, ramipril), especially if you have diabetes-related kidney problems.
  • aliskiren.
  • if you are being treated with an ACE inhibitor together with a medicine that belongs to the class of medicines known as mineralocorticoid receptor antagonists (MRAs). These medicines are used for the treatment of heart failure (see "Other medicines and Karbis").

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 the information under the heading "Do not take Karbis".

If you are in any of these situations, your doctor may want to see you more often and do some tests.

If you are going to have surgery, tell your doctor or dentist that you are taking Karbis. This is because candesartan, in combination with some anesthetics, can cause a pronounced drop in blood pressure.

Children and adolescents

Karbis has been studied in children. For more information, ask your doctor or pharmacist.

Karbis should not be given to children under 1 year of age due to the potential risk to kidney development.

Other medicines and Karbis

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

Karbis may affect the way some medicines work and some medicines may affect the effect of candesartan. If you are using certain medicines, your doctor may need to do blood tests from time to time.

In particular, tell your doctor if you are using any of the following medicines:

  • Other medicines for lowering your blood pressure, including beta-blockers, diazoxide and ACE inhibitors such as enalapril, captopril, lisinopril or ramipril.
  • Non-steroidal anti-inflammatory medicines (NSAIDs) such as ibuprofen, naproxen or diclofenac, celecoxib or etoricoxib (medicines to relieve pain and inflammation).
  • Aspirin (if you take more than 3 g a day) (medicine to relieve pain and inflammation).
  • Potassium supplements or salt substitutes containing potassium (medicines that increase the amount of potassium in your blood).
  • Heparin (a medicine to increase blood fluidity).
    • Co-trimoxazole (an antibiotic) also known as trimethoprim/sulfamethoxazole.
  • Diuretics (medicines to increase urine production).
  • Lithium (a medicine for mental health problems).

Your doctor may need to change your dose and/or take other precautions:

  • if you are taking an ACE inhibitor or aliskiren (see also the information under the headings "Do not take Karbis" and "Warnings and precautions").
    • if you are being treated with an ACE inhibitor together with other specific medicines for treating heart failure, known as mineralocorticoid receptor antagonists (MRAs) (e.g. spironolactone, eplerenone).

Taking Karbis with food, drinks and alcohol

Karbis can be taken with or without food.

When prescribed Karbis, consult your doctor before taking alcohol. Alcohol can make you feel dizzy or faint.

Pregnancy and breastfeeding

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.

Pregnancy

You must tell your doctor if you are pregnant (or think you might be). Normally, your doctor will advise you to stop taking candesartan before you become pregnant or as soon as you find out you are pregnant, and recommend an alternative medicine to take instead of candesartan. It is not recommended to take candesartan during the first trimester of pregnancy and it must not be taken after the third month of pregnancy as it may harm your baby.

Breast-feeding

Tell your doctor if you are breast-feeding or about to start breast-feeding. Karbis is not recommended for women who are breast-feeding, and your doctor may decide to give you a different treatment, especially if you want to breast-feed a newborn or premature baby.

Some patients may feel tired or dizzy when taking Karbis. If this happens to you, do not drive or use tools or machines.

Karbis contains lactose and sodium

If your doctor has told you that you have an intolerance to some sugars, contact them before taking this medicine.

  • Dizziness or lightheadedness.
  • Headache.
  • Respiratory tract infection.
