USES: This medication is a pain reliever and sedative. It is used to relieve tension headaches.
OTHER USES: This medication may also be used to treat pain when a calming effect is also needed.
HOW TO USE: To prevent upset stomach, take this medication with food or milk. Sustained-release preparations must be swallowed whole. Do not crush or chew them as this will destroy the long action and may increase side effects. Pain medications work best in preventing pain before it occurs. Once the pain becomes intense, the medication is not as effective in relieving it. This medication contains acetaminophen. Do not take more acetaminophen than recommended (see Side Effects section). Take this as prescribed. Do not increase your dose or take it more frequently without your doctor's approval.

If these symptoms persist or become bothersome, inform your doctor. If you do not have liver problems, the adult maximum dose of acetaminophen is 4 grams per day (4000 milligrams). If you take more than the maximum daily amount, it may cause serious (possibly fatal) liver disease. Tell your doctor immediately if you have any of the following symptoms of liver damage: severe nausea, yellowing eyes or skin, dark urine, stomach pain, extreme fatigue. An allergic reaction to this drug is unlikely, but seek immediate medical attention if it occurs.
