1. What is Casaro and what is it used for

The active substance of the medicine 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 to lower blood pressure. It also makes it easier for the heart to pump blood to all parts of the body.
Casaro can be used:

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

2. Important information before taking Casaro

When not to take Casaro

If you are unsure whether any of the above situations apply to you, consult your doctor or pharmacist before taking Casaro.

Warnings and precautions

Before starting to take Casaro, discuss it with your doctor or pharmacist:

If any of the above conditions apply to you, your doctor may recommend more frequent checks and blood tests.
If you experience stomach pain, nausea, vomiting, or diarrhea after taking Casaro, discuss it with your doctor. The doctor will decide on further treatment. Do not stop taking Casaro on your own.
Your doctor may recommend regular checks of kidney function, blood pressure, and electrolyte levels (e.g., potassium) in the blood.
If you are planning to have surgery, inform your doctor or dentist that you are taking Casaro. This is because Casaro, in combination with certain anesthetics, may cause a significant drop in blood pressure.

Children and adolescents

The use of Casaro has been studied in children. For further information, talk to your doctor. Casaro should not be given to children under 1 year of age due to the potential risk to kidney development.

Tell your doctor or pharmacist about all medicines you are taking now or have recently taken, as well as any medicines you plan to take.
Casaro may affect the way some other medicines work, and some medicines may affect the way Casaro works.
If you are taking certain medicines, your doctor may periodically recommend blood tests.
In particular, inform your doctor if you are taking any of the following medicines, as your doctor may recommend a dose change and/or other precautions:

  • other blood pressure-lowering medicines, including beta-blockers, diazoxide, and ACE inhibitors, such as enalapril, captopril, lisinopril, or ramipril,
  • non-steroidal anti-inflammatory medicines (NSAIDs), such as ibuprofen, naproxen, diclofenac, celecoxib, or etoricoxib (medicines that relieve pain and inflammation),
  • acetylsalicylic acid (if taken in a dose greater than 3 g per day) (a medicine that relieves pain and inflammation),
  • potassium supplements, potassium-sparing diuretics (medicines that increase potassium levels in the blood),
  • heparin (a medicine that reduces blood clotting),

Before consuming alcohol while taking Casaro, consult your doctor. Alcohol may cause dizziness or fainting.

Pregnancy and breastfeeding

Pregnancy
If you are pregnant or think you may be pregnant, inform your doctor. Your doctor will usually advise you to stop taking Casaro before becoming pregnant or as soon as possible after finding out you are pregnant and recommend taking another medicine instead.
Taking Casaro in early pregnancy is not recommended, and it must not be taken after 3 months of pregnancy, as it may seriously harm the baby.
Breastfeeding

3. How to take Casaro

Always take this medicine exactly as your doctor has told you. If you are unsure, ask your doctor or pharmacist.
It is important to take Casaro every day. Take one tablet each day at the same time. This will help you remember to take your medicine.

High blood pressure
The recommended dose of Casaro is 8 mg once a day. Your doctor may increase the dose to 16 mg once a day, and then to 32 mg once a day, depending on your blood pressure response to treatment.
Some patients, e.g., with liver or kidney problems, or patients who have recently lost a lot of fluid (due to vomiting or diarrhea, or taking diuretics), may be prescribed a lower initial dose by their doctor.
In some black patients, the response to this type of medicine may be reduced when given as the only treatment (monotherapy), and such patients may need a higher dose.

Use in children and adolescents

Children from 6 to 18 years of age:
The recommended initial dose is 4 mg once a day.
Patients with a body weight <50 kg: in some patients with insufficient blood pressure control, the doctor may increase dose of casaro to a maximum 8 mg once day.

The recommended initial dose of Casaro is 4 mg once a day. The doctor may increase the dose by doubling it, at intervals of at least 2 weeks, to 32 mg once a day. Casaro can be taken with other medicines used to treat heart failure, and the doctor will decide which therapy is most suitable for the patient.

Taking a higher dose of Casaro than recommended

If you have taken more Casaro than prescribed by your doctor, contact your doctor or pharmacist immediately.
