Antiarrhythmic medicines are used to control abnormal heart rhythms. However, your doctor will be aware that several antiarrhythmics may be harmful for people with heart failure and should be avoided.
Antiarrhythmic agents include the following classes of medicines:
The side effects of antiarrhythmics depend on which class of medicine you are taking. Talk to your doctor, nurse or pharmacist about the side effects that may occur with the medicine you have been prescribed.
Most people taking calcium channel blockers have either no side effects or only mild headaches and flushing, which tend to ease over a few days. Ankle swelling is common with certain calcium channel blockers.
In some rare cases, amiodarone may increase your skin's sensitivity to sunlight, causing you to burn more easily. You should try to avoid exposure to the sun and sunbeds and use a high-factor sunscreen. Long-term treatment may also affect thyroid function, which must be monitored regularly.
