This page presents data from the FDA Adverse Event Reporting System (FAERS) and the FDA-approved drug label. A report submitted to FAERS does not prove a drug caused the reported event. Always consult a healthcare provider about medications.

Most-Reported Reactions
Counts of the reactions most often cited in FAERS submissions that named Inflectra. Inclusion here does not establish causation - submitters describe what was observed, not what was confirmed. One submission can list several reactions, so the totals exceed the report count.
Patient Demographics
Patient sex and age across the FAERS submissions that named Inflectra. Percentages here are computed only from submissions where these fields were filled in - many leave them blank.

Severity Outcomes
Severity flags recorded across the 214,260 FAERS submissions that named Inflectra. Each bar shows the count of those reports carrying that flag. A single case can carry more than one (a hospitalization that became life-threatening, for example), so these bars are independent rates - they don't sum to 100%. Inclusion of a case under any flag does not establish that the drug caused the outcome.
Submissions Per Quarter
Quarterly count of FAERS submissions that named Inflectra. Ups and downs on this chart can track prescribing volume, news cycles, or shifts in how reports get filed, rather than the drug becoming safer or more dangerous.

Adverse Reactions (from label)
6 ADVERSE REACTIONS Most common adverse reactions (>10%) – infections (e.g. upper respiratory, sinusitis, and pharyngitis), infusion-related reactions, headache, and abdominal pain. ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact CELLTRION, Inc. at 1-800-383-7504 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch . 6.1 Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice. Adverse Reactions in Adults The data described herein reflect exposure to infliximab in 4779 adult patients (1304 patients with RA, 1106 patients with CD, 202 with AS, 293 with PsA, 484 with UC, 1373 with Ps, and 17 patients with other conditions), including 2625 patients exposed beyond 30 weeks and 374 exposed beyond 1 year. [ For information on adverse reactions in pediatric patients see Adverse Reactions (6.1) ] . One of the most common reasons for discontinuation of treatment was infusion-related reactions (e.g., dyspnea, flushing, headache and rash). (continues in label)
