Risedronate Sodium (Risedronate Sodium)
Who reports

Used for
Risedronate sodium tablets, USP are a bisphosphonate indicated for: Treatment and prevention of postmenopausal osteoporosis ( 1.1 ) Treatment to increase bone mass in men with osteoporosis ( 1.2 ) • Treatment and prevention of glucocorticoid-induced osteoporosis ( 1.3 ) • Treatment of Paget's disease ( 1.4 ) Limitations of Use Optimal duration of use has not been determined.
What it is
Risedronate sodium tablets, USP are pyridinyl bisphosphonates that inhibit osteoclast-mediated bone resorption and modulate bone metabolism. Each risedronate sodium tablet, USP for oral administration contains the equivalent of 35, 75, or 150 mg of anhydrous risedronate sodium in the form of the hemi-pentahydrate.

What the badges mean
- 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.
- 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, for the 300 most-reported drugs, adjusted for age band), and flags pairs whose reports are unusually skewed by sex or come mostly from consumers. Each row also shows the PRR against the other drugs of the same FDA class, which removes most confounding by the condition being treated, and a calibrated p-value: on validation, known non-causes average an ROR of about 2, so significance is judged against that empirical null (✓ = p < 0.05 after calibration). 1,215 further terms are in the interactive explorer.

Clinical concept groups
MedDRA splits one clinical problem across several terms (e.g. "neutropenia", "neutrophil count decreased", "agranulocytosis"), which dilutes term-level signals. These rows count reports with any term in a concept group (an exact union, not a sum), compared with all other drugs. Groups are hand-built and listed in the methods.

Trial evidence (ClinicalTrials.gov)
✓ Trial adverse-event data found on ClinicalTrials.gov
Largest completed trials with posted results that list Risedronate as a study intervention. The right-hand column of the signal table shows whether each FAERS term was also recorded in these trials, with a real denominator (1 of 40 signal terms matched).
- NCT02089997 — Special Drug Use Surveillance on Long-term Use of Sodium Risedronate Tablets (Benet 75 mg Tablets) (12-month T (N=3304, phase n/a; 15 AE terms posted; arms: Sodium Risedronate 75 mg)
- NCT01709110 — VERtebral Fracture Treatment Comparisons in Osteoporotic Women (N=1366, PHASE4; 226 AE terms posted; arms: Teriparatide; Risedronate)
Caveats: trial populations, doses and follow-up differ from the reporting population; AE terms are sponsor-coded and matched here by wording; absence from a trial list means the term was not reported above the sponsor's frequency threshold, not that it cannot occur.

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.

Common questions
What are the most reported side effects of Risedronate?
In FDA FAERS, the most frequently co-reported reaction terms for Risedronate are arthralgia, pain, nausea, dyspnoea, fatigue, vomiting. 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 Risedronate have an FDA boxed warning?
No. The FDA label retrieved for Risedronate has no boxed warning; see the label's Warnings and Precautions for the recognised risks.
Do FAERS signals prove that Risedronate 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.
