Flecainide Side Effects

Swelling, feeling faint, and difficulty breathing are some of the side effects of flecainide that require immediate medical treatment. In most cases, however, reactions to this medication are generally mild and easy to treat. During clinical studies of the drug, some of the most commonly reported problems included dizziness, nausea, and loss of strength.

An Introduction to Side Effects of Flecainide

Just like any medicine, flecainide acetate (Tambocor™) can cause side effects. However, not everyone who takes the medication will have problems. In fact, most people tolerate it quite well. If side effects do occur, in most cases, they are minor and either require no treatment or are treated easily by you or your healthcare provider.
