Dronedarone blocks certain electrical signals in the heart that can cause an irregular heartbeat (arrhythmia). This way, it helps to restore normal heart rhythm and maintains a regular, steady heartbeat.

Dronedarone is generally safe to use. However, you should take it in the dose and duration as advised by your doctor. It may cause some side effects that are temporary and usually resolve on their own. Your doctor will tell you ways to cope up with them.

The warning signals of liver toxicity include yellowing of the skin or eyes (jaundice), tiredness, nausea, vomiting, dark-colored urine, pale-colored stools, loss of appetite, stomach pain or high temperature. Contact your doctor immediately if you experience these symptoms.

You may experience blurred vision or see a circle around dazzling light (halos). It may also make your eyes dry or sensitive to light. It can even cause permanent blindness. Therefore, consult your doctor in case you experience any such problems while on Dronedarone.

Dronedarone should be taken exactly as prescribed by your doctor. Usually, it is taken once or twice daily with food. It is to be swallowed whole with water and not to be cut or crushed.

If you forget a dose of Dronedarone take it as soon as you remember. However, if it is nearly time for the next dose, skip the missed dose. Do not double the dose for a forgotten dose. Do not stop taking Dronedarone without consulting your doctor. This is because, sudden discontinuation of the medicine may cause recurrence of irregular rhythm of heart or may be worse which can be dangerous.
