1. What Parapres is and what it is used for

Your medicine is called Parapres. 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 helps lower blood pressure. It also helps the heart pump blood more easily to all parts of the body.

This medicine is used for:

• the treatment of high blood pressure (hypertension) in adult patients and in children and adolescents from 6 years up to but not including 18 years of age.
• the treatment of heart failure in adult patients with heart failure and reduced heart muscle function, when angiotensin-converting enzyme (ACE) inhibitors cannot be used, or in addition to ACE inhibitors when symptoms persist despite treatment and mineralocorticoid receptor antagonists (MRAs) cannot be used. (ACE inhibitors and MRAs are medicines used to treat heart failure).

2. What you need to know before taking Parapres

Do not take Parapres:

• if you are allergic to candesartan cilexetil or to 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 this medicine also during early pregnancy – see Pregnancy section).
• if you have severe liver disease or biliary obstruction (a problem with bile outflow from the gallbladder).
• if the patient is under 1 year of age.
• if you have diabetes or renal insufficiency and are being treated with a blood pressure-lowering medicine containing aliskiren.

If you are unsure whether any of these apply to you, consult your doctor or pharmacist before taking Parapres.

Warnings and precautions

Talk to your doctor before starting Parapres:

• if you have heart, liver or kidney problems, or are undergoing dialysis.
• if you have recently received a kidney transplant.
• if you are experiencing vomiting, have recently had severe vomiting, or have diarrhoea.
• if you have an adrenal gland disorder 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, suspect you might be pregnant, or plan to become pregnant, you must inform your doctor. Use of Parapres is not recommended during early pregnancy (first 3 months) and must under no circumstances be administered from the third month of pregnancy onwards, as it may cause severe harm to your baby – see Pregnancy section.
• if you are taking any of the following medicines used to treat high blood pressure:
  • an ACE inhibitor (e.g., enalapril, lisinopril, ramipril), particularly if you have kidney problems related to diabetes.
  • aliskiren
• if you are taking an ACE inhibitor together with a medicine belonging to a class of medicines known as mineralocorticoid receptor antagonists (MRAs). These medicines are used to treat heart failure. (See “Use of Parapres with other medicines”).

Talk to your doctor if you experience abdominal pain, nausea, vomiting, or diarrhoea after taking Parapres. Your doctor will decide whether to continue treatment. Do not stop taking Parapres on your own.

Your doctor may monitor your kidney function, blood pressure, and blood electrolyte levels (e.g., potassium) at regular intervals.

See also the information in the section “Do not take Parapres”.

If any of these situations apply to you, your doctor may wish to schedule more frequent appointments and perform certain tests.

If you are scheduled for surgery, inform your doctor or dentist that you are taking Parapres. This is because Parapres, in combination with certain anaesthetics, may cause a drop in blood pressure.

Children and adolescents

Parapres has been studied in children. For further information, consult your doctor. Parapres must not be given to children under 1 year of age due to the potential risk of kidney development impairment.

Use of Parapres with other medicines

Inform your doctor or pharmacist if you are using, have recently used, or might need to use any other medicines.

Parapres may affect how certain medicines work, and some medicines may influence the effect of Parapres. If you are taking certain medicines, your doctor may need to perform periodic blood tests.

In particular, inform your doctor if you are taking any of the following medicines, as your doctor may need to adjust your dose and/or take other precautions:

• Other medicines to lower your blood pressure, including beta-blockers, diazoxide, and ACE inhibitors such as enalapril, captopril, lisinopril, or ramipril.
• Non-steroidal anti-inflammatory drugs (NSAIDs) such as ibuprofen, naproxen, diclofenac, celecoxib, or etoricoxib (medicines used to relieve pain and inflammation).
• Acetylsalicylic acid (if taking more than 3 g per day) (a medicine used to relieve pain and inflammation).
• Potassium supplements or salt substitutes containing potassium (medicines that increase potassium levels in your blood).
• Heparin (a medicine used to increase blood fluidity).
• Diuretics (medicines that promote urine elimination).
• Lithium (a medicine used for mental health conditions).
• If you are taking an ACE inhibitor or aliskiren (see also information in sections “Do not take Parapres” and “Warnings and precautions”).
• If you are being treated with an ACE inhibitor together with other specific medicines for heart failure, known as mineralocorticoid receptor antagonists (MRAs) (e.g., spironolactone, eplerenone).

Taking Parapres with food, drinks and alcohol

• You may take Parapres with or without food.
• When Parapres is prescribed to you, consult your doctor before consuming alcohol. Alcohol may make you feel faint or dizzy.

Pregnancy and breastfeeding

Pregnancy

Inform your doctor if you are pregnant, suspect you might be pregnant, or plan to become pregnant. Generally, your doctor will advise you to stop taking Parapres before becoming pregnant or as soon as pregnancy is confirmed, and will recommend an alternative antihypertensive medicine. Use of Parapres is not recommended during early pregnancy and must under no circumstances be administered from the third month of pregnancy onwards, as it may cause severe harm to your baby when administered from that point.

Breastfeeding

Inform your doctor if you are planning to breastfeed or are currently breastfeeding, as Parapres is not recommended for women during this period. Your doctor may decide to prescribe a treatment more suitable for breastfeeding, especially if the infant is a newborn or premature.

Driving and using machines

Some patients may feel tired or dizzy when taking Parapres. If this happens to you, do not drive or operate tools or machinery.

Parapres contains lactose. Lactose is a type of sugar. If your doctor has informed you that you have an intolerance to certain sugars, consult with him before taking this medicine.

4. Possible adverse effects

Like all medicines, this medicine can cause adverse effects, although not everyone will experience them. It is important that you are aware of what these adverse effects might be.

Stop taking Parapres and see a doctor immediately if you experience any of the following allergic reactions:

• Difficulty breathing, with or without swelling of the face, lips, tongue and/or throat
• Swelling of the face, lips, tongue and/or throat, which may cause difficulty swallowing
• Severe itching of the skin (with skin rash)

Parapres may cause a decrease in white blood cells. Your resistance to infections may decrease, and you may feel tired, have an infection, or develop a fever. If this occurs, inform your doctor. Your doctor may perform blood tests from time to time to check that Parapres is not affecting your blood (agranulocytosis).

Other possible adverse effects include:

Frequent (affects 1 to 10 out of every 100 patients)

• Dizziness

• Headache

• Respiratory infection

• Low blood pressure. This may cause dizziness or fainting

• Changes in blood test results:

• An increase in blood potassium levels, especially if you already have kidney problems or heart failure. If this condition is severe, you may experience fatigue, weakness, irregular heartbeat, or tingling

• Effects on kidney function, especially if you already have kidney problems or heart failure. In very rare cases, kidney failure may occur

Very rare (affects less than 1 out of every 10,000 patients)

• Intestinal angioedema: swelling in the intestine causing symptoms such as abdominal pain, nausea, vomiting, and diarrhoea

• Swelling of the face, lips, tongue and/or throat

• A decrease in red blood cells or white blood cells. You may feel tired, or have an infection or fever
