Every ferrous product we track (1)
Same active ingredient — different manufacturer, form, price and FDA recall record. That last one is what our independent score measures.
Only one: Iron.
Combination products containing ferrous
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.
Ferrous recalls
From the FDA Enforcement database. A recall covers specific lots — not the drug as a whole.
How long ferrous keeps
No ferrous 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 ferrous expire? The in-use limits and storage rules from its labelsWhat people report to the FDA about ferrous
The FDA Adverse Event Reporting System (FAERS) collects reports from patients and clinicians. It holds 60,575 reports naming ferrous, and the FDA flagged 77% 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:
- fatigue3,953 reports
- diarrhoea3,863 reports
- dyspnoea3,559 reports
- nausea3,484 reports
- anaemia2,720 reports
- asthenia2,507 reports
- pneumonia2,481 reports
- vomiting2,425 reports
Read these as a signal, not a rate. A report does not mean ferrous 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 ferrous 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 ferrous against whatever else you take — and remember that a label not naming a drug is not the same as that combination being safe.
Is there a generic ferrous?
We do not currently list a generic-labelled ferrous 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 ferrous been recalled?
The FDA's Enforcement database lists 1 recall record whose product description mentions ferrous. The most recent: Ferrous Sulfate 7.5 mg Iron/0.5 mL Oral Syringe (Feb 17, 2025). A recall applies to specific lots, not to the drug as a whole — check the record for the affected lot numbers.
