Who reports
1,305 reports · 53% serious · 46 with death outcome · 77% female
Used for
Monoferric is indicated for the treatment of iron deficiency anemia (IDA) in adult patients: who have intolerance to oral iron or have had unsatisfactory response to oral iron who have non-hemodialysis dependent chronic kidney disease (NDD-CKD) MONOFER.
What it is
Monoferric is an iron replacement product containing ferric derisomaltose for intravenous infusion. Ferric derisomaltose is an iron carbohydrate complex with a matrix structure composed of interchanging layers of ferric hydroxide and the carbohydrate derisomaltose.

What the badges mean
- Labeled adverse reaction The exact term appears in the label's warnings or adverse-reactions sections: a known, expected effect. The FAERS signal confirms the label rather than discovering anything.
- Labeled (related wording) The label describes this effect under different wording (e.g. 'neutropenia' for 'neutrophil count decreased'). Treated as known.
- Likely indication confounding The term appears in the label's indications: reports probably describe the disease being treated (or its progression), not a drug effect. Classic confounding by indication.
- Reporting / coding artifact An administrative, monitoring or exposure term (product issue, off-label use, 'test normal', overdose...). Not a biological reaction; a high PRR here reflects how reports are coded.
- Lab value / disease marker A laboratory result, investigation or disease-activity marker (antibody positive, CRP abnormal, swollen joint count) not described in the label. These usually mirror the monitored disease or testing protocol rather than a drug effect; not screened further.
- Not in label — unassessed Not found in the label text, not an artifact pattern. This is a genuine candidate for a formal causality assessment (Bradford Hill / WHO-UMC); it has NOT had one here.
Strongest disproportionality signals
Flagged terms (PRR ≥ 2, χ² ≥ 4, n ≥ 10), ranked by PRR; infinite PRRs (no comparator reports) excluded. The EBGM column is a second, shrinkage-based estimate (MGPS) with its 5th percentile EB05 and the BCPNN IC025; a pair flagged by PRR alone is marked PRR-only and should be read as fragile. The strata column recomputes the PRR on serious reports only and flags pairs whose reports are unusually skewed by sex or come mostly from consumers rather than clinicians. 12 further terms are in the interactive explorer.

Unlabeled candidate signals
These flagged terms were not found in the FDA label text and do not match an artifact pattern. They are the pairs that would merit a structured assessment (temporality, dose-response, biological plausibility, consistency across databases, trial or cohort evidence). The screen has not done that; string-matching misses label wording, and a strong PRR can still be stimulated reporting, co-medication, or the disease itself.
- Chest discomfort — n=141, PRR 22.2
- Unresponsive to stimuli — n=32, PRR 20.0
- Throat tightness — n=26, PRR 15.5
- Neuralgia — n=20, PRR 13.3
- Throat irritation — n=32, PRR 11.5
- Feeling hot — n=43, PRR 11.3
- Hyperhidrosis — n=60, PRR 7.5

Common questions
What are the most reported side effects of Ferric Derisomaltose?
In FDA FAERS, the most frequently co-reported reaction terms for Ferric Derisomaltose are dyspnoea, flushing, chest discomfort, back pain, infusion related reaction, oxygen saturation decreased. These are report counts, not rates: FAERS has no denominator, reporting is voluntary and uneven, and a term can be reported because of the illness being treated rather than the drug.
Does Ferric Derisomaltose have an FDA boxed warning?
No. The FDA label retrieved for Ferric Derisomaltose has no boxed warning; see the label's Warnings and Precautions for the recognised risks.
Do FAERS signals prove that Ferric Derisomaltose causes these side effects?
No. A disproportionality signal (PRR, ROR) means a reaction is reported more often with this drug than with others in the database. That can reflect a real effect, but also the disease being treated, stimulated reporting after news or litigation, co-medications, or how reports are coded. Causality needs temporality, dose-response, biological plausibility, consistency across data sources and, ideally, trial or cohort evidence. This page screens each term against the FDA label and ClinicalTrials.gov results; it does not establish causation.
