How long phendimetrazine keeps
No phendimetrazine label we read sets a separate limit for after opening, but they do specify how it must be stored — and the stability behind any date assumes those conditions.
What people report to the FDA about phendimetrazine
The FDA Adverse Event Reporting System (FAERS) collects reports from patients and clinicians. It holds 66 reports naming phendimetrazine, and the FDA flagged 38% of those reports as serious. The effects reported most often — leaving out reports about overdose, misuse or the condition being treated, which dominate the raw list for common medicines:
- headache6 reports
- weight increased6 reports
- back pain5 reports
- dyspnoea5 reports
- choroidal effusion4 reports
- fatigue4 reports
- malaise4 reports
- myopia4 reports
Read these as a signal, not a rate. A report does not mean phendimetrazine caused the effect — anyone can file one, and many describe people taking several medicines for several conditions. Crucially there is no denominator: FAERS does not record how many people took the drug, so these counts cannot be turned into “X% of patients” — a bigger number often just means a more widely used or more talked-about drug. Duplicates exist, and publicity drives reporting. For what is actually established, read the FDA label.

Frequently asked questions
Can you take phendimetrazine with other medicines?
It depends on the medicine. We check it against the FDA labels rather than guessing: our interaction checker searches each drug's own label for the other and quotes what it says, naming the section it came from. Run phendimetrazine against whatever else you take — and remember that a label not naming a drug is not the same as that combination being safe.
What brand names is phendimetrazine sold under?
We track 4 phendimetrazine-containing products in the U.S.: Phenazine, Phendimetrazine Tartrate, Plegine and X-Trozine. They are the same active ingredient; they differ in form, manufacturer, price and FDA recall record.
What forms does phendimetrazine come in?
Across the brands we track, phendimetrazine is currently marketed as capsule, capsule, extended release and tablet, per the FDA's National Drug Code Directory. Each form is dosed differently — follow the label for the exact product you were prescribed.
Is there a generic phendimetrazine?
Yes. Our catalog lists 3 generic phendimetrazine products alongside the brand versions. A generic has the same active ingredient and must meet the FDA's bioequivalence standard; it usually costs less. Ask your pharmacist which one your plan covers.
