What acamprosate pills look like
Imprint codes, colour and shape from the FDA’s labelling data. Match the imprint on your pill — or search any imprint.
Acamprosate recalls
From the FDA Enforcement database. A recall covers specific lots — not the drug as a whole.
How long acamprosate keeps
No acamprosate 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 acamprosate
The FDA Adverse Event Reporting System (FAERS) collects reports from patients and clinicians. It holds 464 reports naming acamprosate, and the FDA flagged 87% 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:
- vomiting22 reports
- fall19 reports
- hypotension16 reports
- headache14 reports
- asthenia13 reports
- coma13 reports
- fatigue13 reports
- acute kidney injury12 reports
Read these as a signal, not a rate. A report does not mean acamprosate 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 acamprosate 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 acamprosate 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 acamprosate come in?
Across the brands we track, acamprosate is currently marketed as tablet, delayed 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 acamprosate?
We do not currently list a generic-labelled acamprosate 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.
Has acamprosate been recalled?
The FDA's Enforcement database lists 1 recall record whose product description mentions acamprosate. The most recent: Acamprosate Calcium (Jul 24, 2026). A recall applies to specific lots, not to the drug as a whole — check the record for the affected lot numbers.
