199,312 reports in FDA's adverse event database record the MedDRA term "Wrong technique in product usage process" (in plain words, the product was used in the wrong way): 1% of all reports received between September 2004 and June 2026. Coders pick the term that best matches the reporter's description.

13,472 reports recorded it in the 12 months to June 2026, close to the 14,685 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, 16.5% are marked serious, 1.1% include death among the outcomes and 5.7% include hospitalisation, as reported.

The drugs listed most often as suspect products in those reports are Repatha, Humira and Albuterol sulfate. 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 1% 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 "Wrong technique in product usage process"

What does "Wrong technique in product usage process" mean in an adverse event report?

In plain language: the product was used in the wrong way. 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 wrong technique in product usage process?

199,312 reports through June 2026 (1% of all reports), 13,472 of them in the latest 12 months.

Which drugs appear most often in these reports?

Repatha (22,313), Humira (11,809), Albuterol sulfate (10,722), Neulasta (10,203) and Enbrel (9,979). 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.
