From the FDA Enforcement database. A recall covers specific lots — not the drug as a whole.
How long hydroxocobalamin keeps
The date on a sealed pack is not the only one: some hydroxocobalamin labels start a second clock once the product is opened or mixed, as short as 6 hours.
Does hydroxocobalamin expire? The in-use limits and storage rules from its labelsWhat people report to the FDA about hydroxocobalamin
The FDA Adverse Event Reporting System (FAERS) collects reports from patients and clinicians. It holds 4,466 reports naming hydroxocobalamin, and the FDA flagged 92% 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:
- nausea240 reports
- diarrhoea225 reports
- dyspnoea221 reports
- vomiting200 reports
- dizziness196 reports
- acute kidney injury187 reports
- malaise164 reports
- fatigue162 reports
Read these as a signal, not a rate. A report does not mean hydroxocobalamin 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 hydroxocobalamin 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 hydroxocobalamin 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 hydroxocobalamin come in?
Across the brands we track, hydroxocobalamin is currently marketed as 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 hydroxocobalamin?
Yes. Our catalog lists 1 generic hydroxocobalamin 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.
Has hydroxocobalamin been recalled?
The FDA's Enforcement database lists 1 recall record whose product description mentions hydroxocobalamin. The most recent: B12 Hydroxocobalamin for Injection (Jul 30, 2025). A recall applies to specific lots, not to the drug as a whole — check the record for the affected lot numbers.
