What should I do if I miss a dose of phentermine?

If you miss a dose of phentermine and remember soon afterwards, take your phentermine pill as you remember. However, skip your pill if you are:

  • within 12 hours of your next dose, or 
  • within 8 hours of bedtime
NEVER take a double dose of phentermine.You can overdose on phentermine if you take too much in too little time.

Also exercise caution if it is late in the day. The stimulant properties of phentermine may disrupt your sleep. In general, if you are planning to go to bed in the next eight hours, it’s best to skip the missed dose and take your next pill as usual the next day.
