Used for

Adalimumab-adaz is a tumor necrosis factor (TNF)-blocker indicated for: • Reducing signs and symptoms, inducing major clinical response, inhibiting the progression of structural damage, and improving physical function in adult patients with moderately to severely active rheumatoid arthritis.

FDA label, Indications and Usage

What it is

Adalimumab-adaz is a tumor necrosis factor blocker. Adalimumab-adaz is a recombinant human IgG1 monoclonal antibody with human derived heavy and light chain variable regions and human IgG1:k constant regions.

FDA label, Description section

Boxed warning

SERIOUS INFECTIONS and MALIGNANCY SERIOUS INFECTIONS Patients treated with adalimumab products, including Adalimumab-adaz, are at increased risk for developing serious infections that may lead to hospitalization or death [see Warnings and Precautions ( 5.1 )] .

FDA label
How to read this page. FAERS is a spontaneous-reporting system: counts are not incidence rates and a signal is not proof of causation. Each reaction below is run through an automated screen — is the term in the FDA label (known), in the indications (the disease being treated), an administrative/coding term, or none of these (unlabeled)? That screen is mechanical text matching, not a causality assessment. The 30 hand-written Bradford Hill assessments are on the causality assessment page. Not medical advice.

What the badges mean

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. 1,237 further terms are in the interactive explorer. Reaction links open the term's cross-drug page.

Trial evidence (ClinicalTrials.gov)

✓ Trial adverse-event data found on ClinicalTrials.gov

Largest completed trials with posted results that list Adalimumab-Adaz 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 (0 of 40 signal terms matched).

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.

Most frequently reported reactions

By raw co-report count, regardless of disproportionality. Common terms here are often the illness itself or generic outcomes.

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.

✓ A hand-written Bradford Hill causality assessment exists for this drug: TNF-inhibitors (adalimumab) ↔ Drug-induced lupus.

Want to assess one of these properly? The runbook describes the Bradford Hill / trial-evidence workflow used on the assessment page, and handoff_top1000_signals.csv lists the strongest unassessed pairs across all drugs.

Common questions

What are the most reported side effects of Adalimumab-Adaz?

In FDA FAERS, the most frequently co-reported reaction terms for Adalimumab-Adaz are fatigue, rheumatoid arthritis, pain, arthralgia, rash, diarrhoea. 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 Adalimumab-Adaz have an FDA boxed warning?

Yes. The current FDA label carries a boxed warning: SERIOUS INFECTIONS and MALIGNANCY SERIOUS INFECTIONS Patients treated with adalimumab products, including Adalimumab-adaz, are at increased risk for developing serious infections that may lead to hospitalization or death [see Warnings and Precautions ( 5.1 )] .

Do FAERS signals prove that Adalimumab-Adaz 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.
