(KFYI News) -- A popular painkiller can damage the liver if not used properly. Nurse practitioner Kathleen Wilson is with the "Know Your Dose" campaign, which is all about acetaminophen.
"In a 24-hour period, depending upon what sources the patient may have in terms of medication -- be it prescriptive and/or maybe over-the-counter -- top limit for the 24-hour period is four-thousand milligrams," Wilson says.
Wilson also said it's important to read labels and keep track of how much acetaminophen you're taking. For more information on the campaign, go to www.knowyourdose.org.
