- Checked that no other medicine I am taking also contains acetaminophen
- Asked a doctor first, if I have liver disease
- Asked a doctor or pharmacist first, if I take warfarin
Act now

- Skin reddening, blisters or rash after acetaminophen: stop it and seek medical help right away.[2]
For the pharmacist or prescriber
- Which of my medicines contain acetaminophen, including any prescription pain medicine?
- Is my 24-hour limit lower than the package amount because of my liver, alcohol use or other medicines?
- Relief seems slower since I started Zepbound: should anything change, or should I just keep to the package interval?
- Before a procedure, should acetaminophen be timed differently?
