What darifenacin pills look like
Imprint codes, colour and shape from the FDA’s labelling data. Match the imprint on your pill — or search any imprint.
Can you crush or split darifenacin?
At least one darifenacinproduct is labelled to be swallowed whole — crushing an extended-release tablet releases the whole day’s dose at once. Which applies depends on the form you were given.
What each darifenacin label says about crushing, splitting and chewingHow long darifenacin keeps
No darifenacin 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 darifenacin
The FDA Adverse Event Reporting System (FAERS) collects reports from patients and clinicians. It holds 364 reports naming darifenacin, and the FDA flagged 83% 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:
- herpes zoster77 reports
- synovitis76 reports
- joint swelling71 reports
- arthralgia70 reports
- fibromyalgia70 reports
- peripheral swelling68 reports
- anaemia67 reports
- leukopenia66 reports
Read these as a signal, not a rate. A report does not mean darifenacin 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 darifenacin 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 darifenacin 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 darifenacin sold under?
We track 2 darifenacin-containing products in the U.S.: Enablex and Darifenacin Hydrobromide. They are the same active ingredient; they differ in form, manufacturer, price and FDA recall record.
What forms does darifenacin come in?
Across the brands we track, darifenacin is currently marketed as tablet, extended release, 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 darifenacin?
Yes. Our catalog lists 1 generic darifenacin product 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.
