Overdosage: If you think you have taken too much of L544 pill, contact a poison control center or emergency room at once. According to the U.S. Food and Drug Administration (FDA), taking too much acetaminophen can damage your liver. The recommended maximum daily dose is 4,000 milligrams (mg) per day for adults. However, the difference between a safe dose of acetaminophen and one that may harm the liver is very small.
Other factors add to the risk of liver damage when taking acetaminophen. For example, the chance of liver damage is greater if you already have liver problems, if you drink three or more alcoholic beverages a day, or if you take warfarin. In severe cases, an overdose of acetaminophen can cause liver failure or death.
