Dry mouth, dizziness, mild sedation, and constipation are common side effects of Catapres that may occur but often go away after several doses.

Serious side effects of Catapres include hypotension, bradycardia, congestive heart failure, weakness, and edema. Catapres may increase the effects of alcohol and antidepressants, especially somnolence (sleepiness). Sudden cessation of clonidine treatment has, in some patients, can result in symptoms such as nervousness, agitation, headache, and tremor accompanied or followed by a rapid rise in blood pressure and elevated catecholamine concentrations. No adequate, well-controlled studies have been conducted in pregnant or breastfeeding women; this drug may be used during pregnancy only if clearly needed.
