Xanax (alprazolam) can make you feel calmer, more relaxed, and less anxious, which is why it is commonly prescribed for anxiety and panic disorders. However, it can also cause side effects, especially in the first days or weeks of treatment. These effects may include drowsiness, dizziness, headache, fatigue, irritability, depression, and memory problems.
Other common side effects that can affect how Xanax makes you feel are:
-
Anxiety
-
Disorientation or confusion
-
Insomnia
-
Nausea and/or loss of appetite
-
Blurred vision
-
Loss of balance and abnormal motor coordination
-
Weight gain or weight loss
In many cases, these side effects improve over time as the body adjusts to the medication or when the doctor changes the dosage. Still, although rare, more serious side effects can occur.
If you notice side effects while taking Xanax, especially if they are severe or persistent, it is important to seek medical advice, preferably from the doctor who prescribed the medication. No medication should ever be used without proper medical supervision.
