How long prasterone keeps
No prasterone 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.
Does prasterone expire? The in-use limits and storage rules from its labelsWhat people report to the FDA about prasterone
The FDA Adverse Event Reporting System (FAERS) collects reports from patients and clinicians. It holds 1,137 reports naming prasterone, and the FDA flagged 64% 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:
- fatigue131 reports
- headache121 reports
- nausea104 reports
- dizziness75 reports
- rash66 reports
- diarrhoea62 reports
- dyspnoea61 reports
- asthenia55 reports
Read these as a signal, not a rate. A report does not mean prasterone 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 prasterone 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 prasterone against whatever else you take — and remember that a label not naming a drug is not the same as that combination being safe.
What forms does prasterone come in?
Across the brands we track, prasterone is currently marketed as insert, 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 prasterone?
We do not currently list a generic-labelled prasterone 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.
