Taking sotalol with other medicines and herbal supplements

There are some medicines that may affect the way sotalol works.

Tell your doctor if you're taking any other medicines, including:

• medicines that can cause abnormal heart rhythms – these include some antibiotics, like clarithromycin and erythromycin, and some antidepressants, like citalopram and amitriptyline
• other medicines used to treat an irregular heartbeat, such as amiodarone
• medicines for high blood pressure, such as diltiazem or verapamil
• medicines that can lower your potassium levels – these include medicines that remove extra fluid from your body, like furosemide, and some steroids, like prednisolone
• medicines for asthma or chronic obstructive pulmonary disease (COPD)
• medicines for diabetes, including metformin or insulin
• medicines for allergies, such as ephedrine, noradrenaline or adrenaline

These are not all the medicines that may cause problems if you take them with sotalol. For a full list, see the leaflet inside your medicine packet.
