What is Topamax
Topamax falls under the category of anti-epileptic medications and is approved by the FDA for treating seizure disorders and preventing migraines. One commonly reported side effect of Topamax use for these conditions is weight loss. Consequently, numerous studies have examined its potential as a treatment for weight loss.
While Topamax alone isn’t FDA-approved for weight loss, it can be used off-label for this purpose. However, when combined with another medication called phentermine, Topamax is FDA-approved for weight loss. This combination is marketed under the brand name Qsymia (phentermine/topiramate).
Dosage and Administration
Topamax is typically taken orally in tablet form, with dosages ranging from 25 mg to 200 mg per day. The dosage may vary depending on individual factors such as weight, medical history, and response to treatment. It is important to follow your healthcare provider’s instructions carefully when taking Topamax.
Best Time To Take Topamax for Weight Loss
The timing and frequency of taking Topamax depend on whether you’re using the regular or extended-release (ER) formulation. Regular tablets and capsules might need to be taken twice daily, once in the morning and once at night. ER formulations only need to be taken once a day, ideally at the same time each day.
Your healthcare provider might recommend taking Topamax in the morning to avoid sleep disturbances at night. However, since the medication can make some people drowsy, taking it at night before bed could be a better option in those cases.
