  • Avoid taking phentermine close to bedtime as it can cause problems with falling asleep and staying asleep.

  • Phentermine can make you feel dizzy and drowsy, especially when you first start taking it. Avoid driving or doing anything that requires your complete attention until you know how phentermine affects you.

  • Avoid alcohol while on phentermine as it can make the side effects worse.
