1. What is Osaver and what is it used for

Osaver belongs to a group of medicines called angiotensin II receptor antagonists. They lower blood pressure by widening blood vessels.
Osaver is used to treat high blood pressure, also known as hypertension, in adults and in children and adolescents from 6 to less than 18 years of age. High blood pressure can cause damage to blood vessels in organs such as the heart, kidneys, brain, and eyes. In some cases, this can lead to heart attack, heart or kidney failure, stroke, or blindness. High blood pressure usually does not cause any symptoms. Monitoring blood pressure allows prevention of these damages.
Hypertension can be controlled by taking medicines such as Osaver, coated tablets. To help lower blood pressure, your doctor may also recommend lifestyle changes (e.g., weight loss, quitting smoking, reducing alcohol consumption, and reducing salt intake). Your doctor may also encourage you to engage in regular physical activity, such as walking or swimming. It is essential to follow your doctor's recommendations.

2. Important information before taking Osaver

When not to take Osaver:

Warnings and precautions

Before starting Osaver, discuss it with your doctor or pharmacist.
Tell your doctorif you have any of the following health problems:

Your doctor may recommend regular monitoring of kidney function, blood pressure, and electrolyte levels (e.g., potassium) in the blood.
See also the section "When not to take Osaver".
If you experience severe, persistent diarrhea that causes significant weight loss, contact your doctor. Your doctor will assess your condition and decide how to continue blood pressure treatment.
If you experience stomach pain, nausea, vomiting, or diarrhea after taking Osaver, discuss it with your doctor. Your doctor will decide on further treatment. Do not stop taking Osaver on your own.
As with any blood pressure medicine, excessive lowering of blood pressurein patients with impaired blood flow to the heart or brain may lead to heart attack or stroke. Therefore, your doctor will carefully monitor your blood pressure.
You must inform your doctor about pregnancy, suspected pregnancy, or planned pregnancy. Osaver is not recommended in early pregnancy. You must not take Osaver after the third month of pregnancy, as it may seriously harm your baby (see section "Pregnancy").

Children and adolescents

Olmesartan medoxomil has been studied in children and adolescents. For more information, consult your doctor.
Osaver is not recommended for children under 6 years of age and should not be used in children under 1 year of age, as there is no experience with the use of the medicine in this age group.

Osaver and other medicines

Tell your doctor or pharmacist about all medicines you are taking, have recently taken, or plan to take. This is especially important for the following medicines:

Elderly patients

In patients over 65 years of age, whose dose is increased to 40 mg per day, the doctor will recommend regular blood pressure monitoring to ensure that the blood pressure does not drop too much.

Black patients

As with similar medicines, the blood pressure-lowering effect of Osaver may be slightly weaker in black patients.

Osaver with food and drink

Osaver can be taken with or without food.

4. Possible side effects

Like all medicines, Osaver can cause side effects, although not everybody gets them.
If they do occur, they are usually mild and do not require treatment to be stopped.
The following side effects, although rare, can be serious:

• Uncommon (may affect up to 1 in 100 people): a sudden allergic reaction that can cause difficulty breathing and a sudden drop in blood pressure, which can lead to fainting (anaphylactic reaction).
• Rare (may affect up to 1 in 1,000 people): swelling of the face, mouth, and/or throat, with itching and rash. Rarely (but more frequently in elderly people): Osaver may cause excessive lowering of blood pressure in sensitive individuals or as a result of an allergic reaction. This can lead to severe dizziness or fainting.
• Frequency not known (cannot be estimated from the available data): if you experience yellowing of the whites of the eyes, dark urine, itching of the skin, even if Osaver treatment was started much earlier, you should contact your doctor immediately, who will assess the symptoms and decide how to continue hypertension treatment.

If you experience any of the above symptoms, stop taking Osaver and contact your doctor immediately.
