What Should I Tell My Healthcare Provider Before Taking Adipex-P?

Adipex-P is chemically related to amphetamines. It works by suppressing the appetite, and it may also increase the metabolism.
Only very short studies have evaluated the effectiveness of medications like Adipex-P. In these studies, people taking these medications lost more weight than those not taking them, but the difference was small (only a fraction of a pound more per week for the people taking the weight loss medication). Studies also suggest that the effects of these medications for weight loss decrease after the first few weeks.
General considerations for when and how to take Adipex-P include the following:
- The medication comes in tablet and capsule form. It is usually taken by mouth once daily, although some people may need to take it twice a day.
- Adipex-P should be taken either before breakfast or one to two hours after breakfast.
- This medication should be combined with an appropriate diet. It is not meant to be used without dieting.
- Do not take Adipex-P more often (or at higher doses) than prescribed, as this can lead to addiction or dependence.
- For the medication to work properly, it must be taken as prescribed.
The dose of Adipex-P your healthcare provider recommends will vary, depending on a number of factors, including:
- How you respond to the drug
- Whether you develop bothersome or dangerous side effects
- Other medical conditions you may have
- Other medications you may be taking.
As is always the case, do not adjust your dose unless your healthcare provider specifically instructs you to do so.

If you happen to take too much, seek medical attention immediately.
How Should Adipex Be Stored?

What Should I Do If I Miss a Dose?
If you do not take your Adipex-P as scheduled, take your missed dose as soon as you remember. If it is almost time for your next dose, skip the missed dose and continue with your regular schedule. Do not take a double dose.
