1. What Cabren is and what it is used for

Cabren contains the active substance felodipine. This belongs to a group of medicinces called calcium antagonists. It lowers blood pressure by dilating small blood vessels. It does not negatively affect the heart function.

Cabren is used in the treatment of high blood pressure (hypertension) and heart and chest pain brought on by for example exercise or stress (angina pectoris).

2. What you need to know before you take Cabren Do not take Cabren

-    if you are pregnant. You should tell your doctor as soon as possible if you become pregnant while using this medicine.

-    if you are allergic to felodipine or any of the other ingredients of this medicine (listed in section 6).

-    if you suffer from decompensated heart failure.

-    if you have acute myocardial infarction (heart attack).

-    if you have chest pain of recent onset, or angina pectoris that is lasting for more than 15 minutes or longer or is more severe than usual.

-    if you have disease of a heart valve or heart muscle, until you have talked to your doctor. Warnings and precautions

Cabren, like other blood-pressure lowering medicinal products, may in rare cases lead to pronounced low blood pressure which in some patients may result in an inadequate supply of blood to the heart. Symptoms of excessive low blood pressure and inadequate blood supply to the heart itself, frequently include dizziness and chest pain. If you experience these symptoms, seek emergency care immediately.

Talk to your doctor before taking Cabren, especially if you have problems with your liver.

Taking Cabren may cause your gums to become swollen. Practice good oral hygiene to help avoid your gums from swelling (see section 4).


The use of Cabren is not recommended in children.
