Different classes. Advil is an NSAID; Tylenol is an analgesic and antipyretic. They act on different targets in the body.
Time on the market. Advil was first approved by the FDA in 1984, Tylenol in 1976. That gives Tylenol roughly 8 more years of real-world use and long-term safety data.
Who markets them. Advil is marketed by Haleon; Tylenol by Johnson & Johnson.
Same drug, more than one brand. Ibuprofen is sold as Advil / Motrin — the same active ingredient marketed under different brand names, typically for different approved uses or doses.
Same drug, more than one brand. Acetaminophen is sold as Tylenol / Panadol — the same active ingredient marketed under different brand names, typically for different approved uses or doses.

This is not a recommendation of one drug over the other.
Which medicine is right for a given person depends on their diagnosis, other conditions, other medicines, kidney and liver function, pregnancy, and cost or reimbursement — none of which this page knows. Two drugs in the same class are not automatically interchangeable. Never start, stop or switch a prescription medicine on the basis of a web page; that decision belongs to you and your clinician or pharmacist.
How this page is built
The facts on this page are pulled directly from official U.S. FDA datasets — they are not written from memory.
Each field below names the dataset it came from, so you can check it yourself.
Plain-English summaries and drug-class explainers are written and reviewed by the Priya Life Science editorial
team, led by Sreepriya Prasannan
(MSc Digital Transformation of Life Sciences (Innopharma Education / Griffith College); MSc & BSc Botany).
Data is retrieved automatically from the sources above and cross-checked with AI-assisted verification
(Anthropic's Claude) — brand and generic names are matched against the exact FDA product record so that a
combination product or a different formulation cannot be mistaken for the drug on this page. An editor reviews
the result before publication. We describe this in full in our
editorial standards and corrections policy.
The FDA data on this page was last retrieved on 5 Aug 2026.
Please verify before you rely on this.
This page is general information for life-science and pharmaceutical professionals. It is
not medical advice, and it has not been reviewed by a clinician — our editorial
team holds life-science qualifications, not clinical ones. It is not exhaustive and may not reflect the most
recent label change. Always check the official prescribing information (US Prescribing Information or EU SmPC)
and speak to your doctor or pharmacist before acting on anything here. Drugs in the same class are not
automatically interchangeable, and approvals, brand names and indications differ between the US, the
EU/Ireland (EMA/HPRA) and other regions.
