Question 1

What is Pharmonym?

Accepted Answer

Pharmonym is a free tool that converts between brand and generic drug names and shows uses, dosage, side effects and warnings. The dosage and safety information is drawn from official FDA and UK prescribing information, with plain-English AI summaries and links to the source labels.

Question 2

Can I search for both brand and generic names?

Accepted Answer

Yes. Pharmonym works with both brand names (e.g., Lipitor) and generic names (e.g., atorvastatin). Enter either type of name to see its equivalent. Brand names shown are those registered in the United States.

Question 3

Does Pharmonym compare US and UK drug labels?

Accepted Answer

Yes. When a drug has both a US FDA label and a UK/EU Summary of Product Characteristics (SmPC), Pharmonym shows a side-by-side comparison and an AI summary of the key differences in indications, dosing, contraindications, warnings and adverse reactions.

Question 4

Where does the drug information come from, and is it accurate?

Accepted Answer

Brand and generic names come from RxNorm and the FDA. Dosage, side effects and warnings are taken from official prescribing information (US FDA labels via DailyMed and UK/EU SmPCs), with source links provided. AI is used only to summarise this official text, not to generate facts. Always verify with the full prescribing information before making medical decisions.
