Negative Effects of Xanax

Although most people tolerate
 Xanax® (alprazolam) well, it is not free of negative effects. Because this medication is not suitable for everyone, make sure you talk to your healthcare provider about any possible problems that may apply to you. For instance, make sure your healthcare provider is aware of any other medical conditions you may have and any other medications you are taking before starting treatment with Xanax. Negative effects of this medication include potential side effects. Some of the most common Xanax side effects include:
 
  • Drowsiness
  • Coordination problems
  • Increased appetite.
     
Although negative effects of Xanax tend to be minor, there are some serious side effects of the medication that require immediate medical attention. Contact your healthcare provider right away if you experience problems such as hallucinations, suicidal thoughts, or depression.
 
Other Xanax warnings and precautions apply to women who are pregnant or breastfeeding, as well as people who have certain allergies (including allergies to foods, dyes, or preservatives). Also, you may not be able to take Xanax if you have certain medical conditions, such as glaucoma, liver disease, or lung problems.
