Anxiety Home > Xanax Weight Change

Some people who are taking Xanax® (alprazolam) may notice a weight change. Xanax has been shown to cause weight gain in 27.2 percent of people taking the drug for panic disorder during clinical studies. This risk appears to be smaller for people taking Xanax for other kinds of anxiety. In fact, only 2.7 percent of people taking Xanax for anxiety treatment experienced weight gain. Higher Xanax dosages are often required to treat panic disorder, and this may explain why people with panic disorder have a higher risk of Xanax side effects (including weight gain).
If weight changes occur while taking this medication, there are some things that you can do. Some suggestions include:
  • Eating a heart-healthy diet. This diet should include:


    • Lots of fruits, vegetables, grains, and fat-free or low-fat milk and milk products
    • Lean meats, poultry, fish, beans, eggs, and nuts
    • Foods with little or no saturated fats, trans fats, cholesterol, sodium (salt), and added sugars. 


  • Participating in regular physical activity for at least 30 minutes a day on most days of the week.
Also, talk to your healthcare provider. He or she may have other suggestions or may recommend another medication.
