Combination products containing orphenadrine
A combination is a different drug — different dosing, different warnings. It is listed here so you can find it, not so you can substitute it.
How long orphenadrine keeps
No orphenadrine 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 orphenadrine
The FDA Adverse Event Reporting System (FAERS) collects reports from patients and clinicians. It holds 912 reports naming orphenadrine, and the FDA flagged 74% 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:
- nausea68 reports
- fatigue59 reports
- anxiety54 reports
- arthralgia53 reports
- diarrhoea53 reports
- headache53 reports
- dizziness46 reports
- fall44 reports
Read these as a signal, not a rate. A report does not mean orphenadrine 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 orphenadrine 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 orphenadrine 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 orphenadrine sold under?
We track 2 orphenadrine-containing products in the U.S.: Disipal and Norflex. They are the same active ingredient; they differ in form, manufacturer, price and FDA recall record.
What forms does orphenadrine come in?
Across the brands we track, orphenadrine is currently marketed as tablet, tablet, extended release and injectable, 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 orphenadrine?
We do not currently list a generic-labelled orphenadrine 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.
