How To Use Phentermine

Phentermine is available as an oral capsule and oral tablet to take by mouth 1-3 times a day as prescribed. You can take phentermine with or without food. Your doctor may ask you to take phentermine as a single daily dose in the morning or up to 3 times a day before meals. 

You should avoid taking phentermine in the late evening as it can lead to insomnia (difficulty falling asleep and staying asleep).

If you are taking the extended-release phentermine tablets, do not cut, crush, or chew these tablets. 

Read the prescription label carefully and take phentermine in the exact way as instructed by your doctor. Phentermine can be habit-forming. Do not take a higher or lower dose of this medicine or take it more or less frequently than prescribed. Most people are prescribed phentermine for 3-6 weeks, depending on their initial body mass index. 

This medication works best with a diet and exercise program. Follow the calorie-restricted diet and exercise program your doctor recommends to have phentermine work.

Missed dose: If you forget to take a dose of phentermine, take it as soon as you remember. However, if it is almost time for your next dose, skip the missed dose and take the next dose according to your regular dosing schedule. Do not take two doses together to make up for a missed dose.

Storage: Store phentermine at room temperature (between 15-30° C or 59-86° F) away from moisture, heat, and direct light in a tightly closed container. Do not store medications in the bathroom, where they can be exposed to moisture and heat. Keep all medications safely out of reach of children and pets.

Unused medicine: Unused or expired phentermine should be disposed of in a way that children, other people, and pets cannot get to them. Do not throw phentermine in the trash or flush it down the toilet. The best way to dispose of expired or unneeded phentermine is through your local waste disposal company or a drug take-back program.
