• The recommended first (initial) dose is 80mg, given in either one or two divided doses.
• Dosage should be adjusted gradually allowing 2-3 days between dosing stages.
• Most patients will respond to a daily dose of 160–320mg given in two divided doses at approximately 12 hour intervals.

Some patients with life threatening heart problems may need higher doses of up to 480–640mg per day. These doses should be given under specialist supervision and should only be prescribed when the potential benefit outweighs the increased risk of side effects (adverse events).

Patients suffering from kidney problems will require a lower dose.

Sotalol tablets should not be given to children.

If you accidentally take too many tablets, contact your doctor or nearest hospital emergency department immediately for advice. Remember to take this leaflet or any remaining tablets with you.

Symptoms of overdose include: slower heartbeat (bradycardia), heart failure, low blood pressure (hypotension), difficulty in breathing or wheezing (bronchospasm), low blood sugar levels (hypoglycaemia).
