What this medicine is used for
The name of your medicine is APO-Sotalol Tablets. It contains the active ingredient sotalol hydrochloride.
It is used to prevent and treat an irregular heart rhythm or heartbeat. This is called "arrhythmia".
Ask your doctor if you have any questions about why this medicine has been prescribed for you. Your doctor may have prescribed this medicine for another reason.
This medicine is available only with a doctor's prescription.
How it works
Sotalol belongs to a group of medicines called beta-blockers. It works by changing the body's response to some nervous impulses, especially in the heart. By doing so, sotalol helps the heart to beat more regularly and reduce the effort to which the heart has to pump blood.
There is no evidence that this medicine is addictive.
Use in children
This medicine should not be used in children.

Take your medicine on an empty stomach, at least half an hour (ideally 1-2 hours) before, or two hours after, a meal or milk-containing products.

Make sure you have enough to last over weekends and holidays.
If you forget to take it
If it is almost time for your next dose, skip the missed dose and take your next dose at the usual time.
Otherwise, take it as soon as you remember, and then go back to taking your medicine as you would normally.
Do not take a double dose to make up for the dose that you missed.

If you take too much (overdose)
If you think that you or anyone else may have taken too much of this medicine, immediately telephone your doctor or the Poisons Information Centre (Tel: 13 11 26 in Australia) for advice. Alternatively, go to the Accident and Emergency department at your nearest hospital.

While you are taking sotalol
Things you must do

- you are pregnant or are planning to become pregnant
- you are breastfeeding or are planning to breast-feed
- you are about to have any blood tests
- you are going to have surgery or an anaesthetic or are going into hospital.
If you have a history of allergies, there is a chance that sotalol may cause allergic reactions to be worse or harder to treat.
If you are being treated for diabetes, make sure you check your blood sugar levels regularly. Sotalol may affect how well your diabetes is controlled. It may also cover up some of the symptoms of low blood sugar (also called hypoglycaemia), such as a fast heartbeat. Sotalol may also make low blood sugar last longer. Your doctor may need to change the dose of diabetes medicines (such as insulin).
Go to your doctor regularly for a check-up.
Your doctor may occasionally do tests to make sure the medicine is working and to prevent side effects.
Tell any other doctors, dentists and pharmacists who are treating you that you take this medicine.

- Give this medicine to anyone else, even if their symptoms seem similar to yours.
- Take your medicine to treat any other complaints unless your doctor tells you to.
- Stop taking your medicine, or change the dosage, without checking with your doctor.
Things to be careful of
Be careful while driving or operating machinery until you know how medicine affects you.
As with other medicines, sotalol may cause dizziness, light-headedness or drowsiness in some people. If this occurs do not drive or operate machinery or any other activity that could be dangerous if dizzy, light-headed or drowsy.
Dizziness, light-headedness or fainting may occur, especially when you get up from a sitting or lying position. Getting up slowly may help.
Make sure you drink enough water in hot weather and during exercise when you are taking sotalol, especially if you sweat a lot.
If you do not drink enough water while taking sotalol, you may feel faint or light-headed or sick. This is because your blood pressure is dropping suddenly. If you continue to feel unwell, tell your doctor.
