Who reports
3,097 reports · 54% serious · 99 with death outcome · 65% female
Used for
EXPAREL is indicated to produce postsurgical: Local analgesia via infiltration in patients aged 6 years and older Regional analgesia via an interscalene brachial plexus nerve block in adults Regional analgesia via a sciatic nerve block in the popliteal.
What it is
EXPAREL (bupivacaine liposome injectable suspension) is a sterile, non-pyrogenic white to off-white preservative-free aqueous suspension consisting of multivesicular liposomes containing bupivacaine. Bupivacaine is present at a concentration of 13.3 mg/mL.

Causality screen of the 40 strongest signals
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.
- 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.
- 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. 78 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.
- Joint range of motion decreased — n=98, PRR 50.0
- Rotator cuff syndrome — n=23, PRR 12.1
- Osteoarthritis — n=42, PRR 6.7
- Anaphylactic shock — n=25, PRR 6.6
- Staphylococcal infection — n=32, PRR 6.5
- Movement disorder — n=24, PRR 5.0

Common questions
What are the most reported side effects of Bupivacaine and Epinephrine Bitartrate?
In FDA FAERS, the most frequently co-reported reaction terms for Bupivacaine and Epinephrine Bitartrate are musculoskeletal pain, joint injury, joint range of motion decreased, hypoaesthesia, cardiac arrest, musculoskeletal discomfort. 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 Bupivacaine and Epinephrine Bitartrate have an FDA boxed warning?
No. The FDA label retrieved for Bupivacaine and Epinephrine Bitartrate has no boxed warning; see the label's Warnings and Precautions for the recognised risks.
Do FAERS signals prove that Bupivacaine and Epinephrine Bitartrate 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.
