Dronedarone STADA – Dronedarone uses, dose and side effects


400 mg film-coated tablets 

What Dronedarone STADA is and what it is used for

Dronedarone Stada contains an active substance called dronedarone. It belongs to a group of medicines called antiarrhythmics that help regulate your heart rhythm.

Dronedarone Stada is used if you have problems with your heart rhythm (your heart beats irregularly – so-called atrial fibrillation ) and a treatment called conversion has restored your heart rhythm to a normal rhythm. Dronedarone Stada prevents your problems with an irregular heartbeat from recurring.

Your doctor will consider all available treatment options before prescribing Dronedarone Stada.

Dronedarone contained in Dronedarone Stada may also be approved for the treatment of other conditions not mentioned in this product information. Ask your doctor, pharmacist, or other healthcare professional if you have any further questions, and always follow their instructions.

2. What you need to know before you use Dronedarone STADA

Do not use Dronedarone STADA

  • if you are allergic to dronedarone or any of the other ingredients of this medicine (listed in section 6)
  • if you have problems with conduction disturbances in the heart (heart block), which can cause very slow heart rhythm or dizziness. If you have been given a pacemaker for such symptoms, you can use Dronedarone Stada
  • if you have a very slow heart rate (less than 50 beats per minute)
  • if your ECG ( electrocardiogram ) shows that you have a heart problem called “prolonged QTc time” (this interval is over 500 milliseconds)
  • if you have a type of irregular heartbeat called permanent atrial fibrillation. In permanent atrial fibrillation, the flicker has been present for a long time (for at least 6 months) and a decision has been made not to restore your heart rhythm to normal rhythm using conversion.
  • if you have or have had problems where your heart can not pump around the blood in the body as well as it should ( heart failure ). You may have swollen feet or legs, difficulty breathing when lying down or sleeping, or shortness of breath when moving.
  • if the amount of blood that leaves your heart each time it contracts is too small (left ventricular dysfunction)
  • if you have previously used amiodarone (another antiarrhythmic ) and experienced lung or liver problems,
  • if you are taking medicines for infections (including fungal infections or AIDS ), allergies, heart rhythm problems or depression, or medicines given after a transplant (see the section below “Other medicines and Dronedarone Stada.” This section gives you more information about which medicines you can not bring Dronedarone Stada)
  • if you have severe liver problems
  • if you have severe kidney problems
  • if you are taking dabigatran (see section “Other medicines and Dronedarone Stada” below).

If any of the above apply to you, do not take Dronedarone Stada.

Warnings and cautions

Talk to your doctor or pharmacist before taking Dronedarone Stada about:

  • You have a problem that causes you to have low levels of potassium or magnesium in your blood. This problem should be treated before starting treatment with Dronedarone Stada
  • you are older than 75 years
  • you have a condition where your blood vessels, which supply the heart muscle with blood, become hardened and narrower (coronary heart disease).

While taking Dronedarone Stada, talk to your doctor about:

  • your atrial fibrillation becomes permanent while you are being treated with Dronedarone Stada. If this happens, stop using Dronedarone Stada.
  • you have swollen feet or legs, difficulty breathing when you lie down or sleep, become short of breath when you move or gain weight (which are signs and symptoms of heart failure ).
  • inform your doctor immediately if you develop any of these signs and symptoms of liver problems: abdominal pain or discomfort, loss of appetite, nausea, vomiting, yellowing of the skin or whites of the eyes (jaundice), abnormally dark urine, fatigue (especially in connection with other symptoms such as indicated above), itching
  • you are short of breath or have a dry cough. Talk to your doctor who will examine your lungs.

If this happens to you (or you are not sure) talk to your doctor or pharmacist before taking Dronedarone Stada.

Tests on heart, lungs, and blood

When you are being treated with Dronedarone Stada, your doctor may perform tests to check your medical condition and how the medicine is working for you.

  • Your doctor can monitor your heart’s electrical activity using an ECG ( electrocardiogram ).
  • Your doctor will order blood tests to check your liver function before you start taking Dronedarone Stada and also during treatment.
  • If you are taking certain blood-thinning drugs such as warfarin, your doctor will order a blood test called PK (INR) to check how well your drug is working.
  • Your doctor may also take other blood samples. The results of one of these blood tests, which check kidney function (blood creatinine levels), may be altered by Dronedarone Stada. Your doctor will keep this in mind when testing your blood levels and will use a different limit on the normal value of blood creatinine.
  • Your doctor may examine your lungs.

In some cases, treatment with Dronedarone Stada may need to be stopped.

Tell other people who control your blood that you are taking Dronedarone Stada.
