Clonidine Side Effects

Depending on the particular product, common side effects of clonidine may include dry mouth, fatigue, constipation, and vomiting. Most side effects mild and do not require medical attention in most cases, but you should contact your healthcare provider immediately if you experience problems such as lightheadedness, fainting, chest pain, or difficulty breathing.

An Introduction to Clonidine Side Effects

As with any medicine, side effects are possible with clonidine hydrochloride (Catapres^®, Catapres-TTS^®, Duraclon^®, Kapvay™, Nexiclon^® XR). 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 can easily be treated by you or your healthcare provider.

(This article covers many, but not all, of the possible side effects with clonidine. Your healthcare provider can discuss a more complete list of clonidine side effects with you.)
