"Intentional product use issue" (in plain words, deliberate use not as intended) is a MedDRA preferred term recorded in 86,792 adverse event reports received by FDA, 0.4% of the database, from May 2004 to June 2026. The term is chosen by whoever codes the report to match what the reporter described.

6,177 reports recorded it in the 12 months to June 2026, close to the 6,424 of the 12 months before. FDA releases FAERS data quarterly, so the newest months are incomplete and grow in later releases. Of reports recording this term, 67.8% are marked serious, 10.9% include death among the outcomes and 22.4% include hospitalisation, as reported.

The drugs listed most often as suspect products in those reports are Infliximab, Rituximab and Inflectra. That order mostly follows how many reports each drug has overall; the table also gives the term's share within each drug's own reports. FDA states that "a causal relationship cannot be established between product and reactions listed in a report" and that for any given report "there is no certainty that a suspected drug caused the event."

Drugs with a page on this site, ordered by the number of their reports recording this term. The last column is the term's share within that drug's own reports, against 0.4% across the whole database. FDA states that adverse event reports "represent a small percentage of total usage numbers of a product", that "common products may have a higher number of adverse events due to the higher total number of people using the product", and that the data "by themselves are not an indicator of the safety profile of the drug or biologic."

Questions about "Intentional product use issue"

What does "Intentional product use issue" mean in an adverse event report?

In plain language: deliberate use not as intended. It is a MedDRA preferred term, the dictionary FDA uses to code what a reporter described. The report's own description is not published by openFDA and is not shown here.

How many reports record intentional product use issue?

86,792 reports through June 2026 (0.4% of all reports), 6,177 of them in the latest 12 months.

Which drugs appear most often in these reports?

Infliximab (9,906), Rituximab (8,313), Inflectra (8,158), Remicade (4,940) and Actemra (4,450). Drugs with many reports overall lead almost every term's list. FDA states that adverse event reports "represent a small percentage of total usage numbers of a product", that "common products may have a higher number of adverse events due to the higher total number of people using the product", and that the data "by themselves are not an indicator of the safety profile of the drug or biologic."

Does a drug appearing here mean it was responsible for this reaction?

No. FDA states that "a causal relationship cannot be established between product and reactions listed in a report" and that for any given report "there is no certainty that a suspected drug caused the event."

I have this symptom. What should I do?

This site cannot assess anyone. A pharmacist or clinician can; for an emergency, call the local emergency number. Nothing on this page is medical advice.

Where this comes from. Counts are built from the openFDA Drug Adverse Event (FAERS) bulk export released 28 Sep 2026, which holds reports FDA received through 30 Jun 2026. Drug names are as reported, resolved to the brand or generic name on the FDA label where openFDA's harmonisation matched them; classes are the pharmacologic class (EPC) from the label and the National Drug Code Directory of 17 Sep 2026. Terms are pooled across spelling and capitalisation variants of one MedDRA preferred term. No report narrative, lot number, patient detail or reporter identity is published. See the methodology and sources; FDA's record is authoritative, and corrections are handled within five working days.
