Common Side Effects of Xanax
Xanax may cause some side effects. You should let your doctor know if they are severe or don't go away. They may include but aren't limited to:
  • Drowsiness, light-headedness, dizziness, irritability, or fatigue
  • Headaches or difficulty concentrating
  • Talkativeness
  • Dry mouth or increased saliva production
  • Changes in sex drive
  • Constipation
  • Nausea or weight changes
  • Difficulty in urination
  • Joint pain
Let your doctor know immediately if you feel short of breath, have seizures, are hallucinating, or get a severe skin rash when taking Xanax. The same is true if you have yellowing of your skin or eyes, feel depressed, have memory problems, are confused, have trouble speaking, feel suicidal or have other changes in mood, or have problems with coordination or balance.

If you forget a dose of Xanax, take it as soon as you remember, unless it is time for your next dose of Xanax. In that case, skip the missed dose of Xanax and return to your regular schedule. Store Xanax at room temperature, away from excess heat, light, or moisture.

Your doctor may decide to give you a lower dose of Xanax if you are older than age 65. Tell your doctor if you are taking any other medicines or supplements, especially St. John's wort, because they may interact with Xanax. Your doctor may choose a different medicine than Xanax if you have glaucoma. Be sure to tell your doctor if you are pregnant or become pregnant while taking Xanax.
