What people report to the FDA about fluoxymesterone
The FDA Adverse Event Reporting System (FAERS) collects reports from patients and clinicians. It holds 51 reports naming fluoxymesterone, and the FDA flagged 94% 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:
- diabetes mellitus13 reports
- secondary hypogonadism10 reports
- autoimmune thyroiditis9 reports
- haematocrit increased7 reports
- performance enhancing product use7 reports
- blood glucose increased6 reports
- glucose tolerance decreased6 reports
- renal failure acute5 reports
Read these as a signal, not a rate. A report does not mean fluoxymesterone 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 section above.

Frequently asked questions
Can you take fluoxymesterone 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 fluoxymesterone 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 fluoxymesterone sold under?
We track 2 fluoxymesterone-containing products in the U.S.: Ora-Testryl and Halotestin. They are the same active ingredient; they differ in form, manufacturer, price and FDA recall record.
What forms does fluoxymesterone come in?
Across the brands we track, fluoxymesterone is currently marketed as 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 fluoxymesterone?
We do not currently list a generic-labelled fluoxymesterone product. That does not always mean none exists — it means none appears under a generic name in the FDA data we track. Ask your pharmacist.
