Phentermine/Topamax combination is used as a weight-management medication that is prescribed to overweight or obese people, who also have one or several medical conditions related to excessive weight. The extended-release capsules of Phentermine and Topamax are recommended for use together with a low-calorie diet and increased physical activity. Phentermine works as an appetite suppressant as it belongs to a class of anorectics, while Topamax (generic name – Topiramate) is an anticonvulsant drug. Topamax and phentermine, taken together, reduce a person’s appetite and prolong the feeling of satiety.
The medications are to be taken by mouth once a day, usually in the morning, because if taken in the evening, they could prevent you from sleeping well or falling asleep at all. You can take the extended-release capsules with disregard to meals. The effective Phentermine/Topiramate dosage differs from a person to person, but the usual starting dose is a low one – 37.5 mg of Phentermine and 23 mg of Topiramate. After a week or two, your doctor will probably recommend you to increase the dose, as the starting one might not be effective. Do not increase Phentermine/Topamax dosage on your own without your doctor’s recommendation. As a rule, you should undergo a check after 12 weeks of the treatment and depending on whether or not you lost some weight or what amount you lost, your doctor will either recommend you to continue with the same dose, increase it, or stop taking the medication.

If during this period you have not lost the necessary amount of weight, you should stop taking the medication.
In case of a missed dose, just take your next dose as usual the following day. Do not double the dose even if you miss one.
