Not Medical Advice: White, capsule-shape pill with L544 imprint has been identified as Acetaminophen extended release 650 mg.
Acetaminophen is a pain reliever and fever reducer. It is used to treat many conditions such as headache, muscle pain, arthritis, backache, toothaches, colds, sciatica, plantar fasciitis and more.
In an article from CBS News, millions of people a year take over-the-counter drugs that contain acetaminophen, and hundreds of them die from overdoses of that medication. Under growing government pressure and facing lawsuits, the maker of Tylenol, McNEIL-PPC, Inc., is now putting a new warning label on its cap that says "contains acetaminophen, always read the label."
The warning is to make it explicitly clear that Tylenol products contain acetaminophen, a pain reliever that's long been connected to liver failure and overdose.
