Then take one capsule every hour as needed until the headache is relieved. Do not take more than 5 capsules in a 12 hour period. In tension headaches, usually no more than 8 capsules a day are recommended. Do not exceed the maximum dose prescribed. This medication contains acetaminophen. Do not take more acetaminophen than recommended (see Side Effects section).

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.

Consult your pharmacist if you are uncertain if your other prescription or nonprescription products contain acetaminophen. (Also see maximum daily dose information in Side Effects section).
