An Overview of Labetalol Side Effects

As with any medicine, side effects can occur with labetalol hydrochloride (Trandate®). However, not everyone who takes the drug will experience problems. In fact, most people tolerate it well. If side effects do occur, they are generally minor and either require no treatment or can be treated easily by you or a healthcare provider. Serious reactions are much less common.
