Sotalol Side Effects

General weakness, shortness of breath, and dizziness are some of the most commonly reported sotalol side effects. Rare problems that were reported in 1 percent to 4.1 percent of people using the drug include back pain, fever, and insomnia. There are also a number of side effects that are potentially serious and require prompt medical attention, including hives, fainting, and bradycardia.

An Introduction to Sotalol Side Effects

As with any medicine, side effects are possible with sotalol hydrochloride (Betapace®, Sorine®). However, unlike many other medications, sotalol can often cause life-threatening side effects. For this reason, the drug should only be used if the benefits clearly outweigh the potentially dangerous side effects.
 
(This article covers many, but not all, of the possible side effects with sotalol. Your healthcare provider can discuss a more complete list of sotalol side effects with you.)
