Frequently asked questions
- What does Gastromark treat?
- Gastromark (Ferumoxsil) may be used to treat anemia, based on NIH RxClass drug-classification data (conditions a drug may treat — not a verbatim copy of the FDA-approved label). This is general reference, not medical advice.

To pay less, ask your prescriber or pharmacist whether a generic equivalent exists, check the manufacturer's copay/savings card and patient-assistance program, and compare a pharmacy discount card against your insurance copay. Prices vary by pharmacy, insurance, and location, so always confirm at the counter. This is general reference, not medical or financial advice.

What people report to the FDA about FERUMOXSIL
The FDA Adverse Event Reporting System (FAERS) collects reports from patients and clinicians. It holds 6 reports naming FERUMOXSIL — the active ingredient in Gastromark, and the FDA flagged 100% 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:
- urticaria3 reports
- angioedema2 reports
- erythema2 reports
- hypersensitivity2 reports
- abnormal weight gain1 reports
- blood pressure increased1 reports
- bone disorder1 reports
- cardiovascular disorder1 reports
Read these as a signal, not a rate. A report does not mean FERUMOXSIL 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.
