Catapres-TTS Side Effects
In clinical studies, some of the most commonly reported side effects of Catapres-TTS were skin irritation at the patch site, drowsiness, and headaches. In most cases, side effects of this medication either do not require medical attention or can be treated easily. However, some side effects are potentially serious and should be reported to your healthcare provider right away, including fainting, hallucinations, or anxiety.
As with any medicine, side effects are possible with Catapres-TTS® (clonidine hydrochloride). However, not everyone who takes the medication will experience side effects. 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 Catapres-TTS. Your healthcare provider can discuss a more complete list of Catapres-TTS side effects with you.)
Catapres-TTS has been studied thoroughly in clinical trials. In these studies, the side effects that occur in a group of people taking the drug are documented and are then compared to side effects that occur in another group of people not taking the medicine. This way, it is possible to see what side effects occur, how often they appear, and how they compare to the group not taking the medicine.
In these studies, the most common Catapres-TTS side effects included:
- Skin irritation at the patch site -- in up to 51 percent of people
- Dry mouth -- up to 25 percent (see Clonidine and Dry Mouth)
- Drowsiness -- up to 12 percent
- Fatigue -- up to 6 percent
- Headache -- up to 5 percent
- Darkening of the skin at the patch site -- up to 5 percent.
Other, less common side effects included but were not limited to:
- Sedation (a drowsy, "out of it" state)
- Sexual problems (see Clonidine Sexual Side Effects)
- Dry throat
- Changes in taste
