Phentermine and Topiramate Dosage

General Information on Taking Phentermine and Topiramate

Some considerations to keep in mind during treatment with phentermine and topiramate include the following:
  • You can take your dose with or without food. Try taking it with food if it upsets your stomach.
  • You should take your dose in the morning, as taking it later in the day could cause insomnia.
  • Take this medication at the same time each day, to keep an even level of the drug in your bloodstream.
  • Do not stop taking this medication suddenly, as doing so could cause serious problems, such as seizures. If you no longer need it, your healthcare provider may want to gradually reduce your dose.
  • Phentermine and topiramate is used in combination with a reduced-calorie diet and exercise program. Make sure to follow your complete weight loss program for the best results.
  • For the medication to work properly, it must be taken as prescribed. Taking more than the recommended amount could increase your risk for serious side effects.
  • If you are unsure about anything related to your dosage, please talk with your healthcare provider, nurse, or pharmacist.
