Anxiety Home > Xanax Side Effects
Drowsiness, fatigue, and coordination problems are some of the most common side effects reported with Xanax. In most cases, side effects of the medication are minor, requiring little or no treatment. There are, however, a number of potentially serious side effects with Xanax that should be reported to a healthcare provider right away. Among them include suicidal thoughts, yellowing eyes or skin, and hallucinations.
As with any medicine, side effects are possible with Xanax® (alprazolam); 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 Xanax. Your healthcare provider can discuss a more complete list of Xanax side effects with you.)
Xanax 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 problems occur, how often they appear, and how they compare to the group not taking the medicine.
In these studies, some of the most common side effects of Xanax included:
- Drowsiness -- in up to 76.8 percent of people
- Fatigue and tiredness -- up to 48.6 percent
- Coordination problems -- up to 40.1 percent
- Irritability -- up to 33.1 percent
- Memory problems -- up to 33.1 percent
- Increased appetite -- up to 32.7 percent.
Some other common side effects, occurring in 1 percent to 30 percent of people, included:
- Speech problems
- Changes in sex drive or other sexual problems (see Xanax Sexual Side Effects)
- Unusual dreams
- Feeling warm
- Increased salivation
- Nasal congestion
- Decreased appetite
- Weight loss or weight gain (see Xanax and Weight Gain)
