4,930 adverse event reports received by FDA list the brand name Tylenol 8 HR Arthritis Pain (acetaminophen) as a suspect or interacting product, from September 2010 to June 2026. A further 618 reports list it only as a concomitant medication, and those are not counted in the figures on this page.
In the 12 months to June 2026, 348 reports listed it, down 23% from 451 in the 12 months before. FDA releases FAERS data quarterly, so the newest months are incomplete and grow in later releases. Over its reporting history that is about 311 reports a year and 0% of the 20,646,523 reports in the database. How many people take it is not in the data, so a count is not a rate of occurrence.
The reactions recorded most often are incorrect dose administered (31.1%), inappropriate schedule of product administration (22%) and drug ineffective (14.7%). A report can list several reactions, so shares add to more than 100%; 228 different terms appear across these reports. Incorrect dose administered is recorded in 31.1% of these reports, against 1.1% of all reports in the database.
2.8% of the reports are marked serious by the reporter; 0.3% record death among the outcomes and 0.7% record hospitalisation, as reported. 98.3% of the reports came from consumers, and the largest patient age group is 75 and over (25.7%). 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."

Top 30 of 228 MedDRA preferred terms recorded across these reports, with a plain-language gloss where one is available. One report can record several terms. The hollow bar is the share of all reports in the database; it describes the reports, not the patients. 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."
Outcomes recorded
Outcome flags as the reporter set them; a report can carry several, and "other serious" is FDA's own category for serious reports outside the named outcomes. Grey bar: all 20,646,523 reports. FDA has not verified any outcome and states that the reports "cannot be used to estimate the incidence of these events."

Shares are of reports, not of patients treated. The number of people taking a product is not in the data, so none of these figures is a rate, and differences between columns reflect who takes a product, who reports and how long it has been sold. 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."

Are reports for Tylenol 8 HR Arthritis Pain rising?
348 reports in the 12 months to June 2026, down 23% from 451 in the 12 months before. FDA releases FAERS data quarterly, so the newest months are incomplete and grow in later releases. Counts also move with how many people take a product, its time on the market and publicity.
Do these reports show that Tylenol 8 HR Arthritis Pain was responsible for these reactions?
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." The reaction may relate to the condition being treated, to other medicines, or to something else.
Is this a list of the side effects of Tylenol 8 HR Arthritis Pain?

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. A report counts here when it lists Tylenol 8 HR Arthritis Pain as a suspect or interacting product; reports listing it only as a concomitant medication (618) are excluded. 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.
