Common side effects of this medication include drowsiness, dizziness, and headache. Please notify your physician immediately if these adverse reactions persist or become severe.
Also, inform your doctor if you have low magnesium or potassium blood levels, heart failure, liver disease, or have experienced fainting and death while taking this medication. Doing so increases your risk for long QT syndrome, which may increase fainting risk significantly and should be avoided if pregnant or taking other medicines that contain lithium.

Activated charcoal may react negatively with certain medications; if you are taking such a combination, it is advised to wait at least 2 hours before breastfeeding.
This medication may cause disruptions in your heart rhythm, with this risk increasing if you have certain conditions or take other drugs that increase it (i.e., slow the heart’s pumping action, such as with amiodarone or anticholinergics such as atropine or alprazolam).
