how long does it take for acetaminophen to relieve pain
The effect of aspirin begins 30 to 60 minutes after you take it. (Coated aspirin may need 1 to 8 hours to work.) The pain-relieving action of one dose usually lasts about 4 hours but may last up to 12 hours. Acetaminophen relieves pain within 10 to 60 minutes of taking it. Its effect may last up to 6 hours. Ibuprofen begins to relieve pain in 1 to 2 hours and lasts from 5 to 10 hours. You may need to take ibuprofen for 2 to 3 days before you get the most pain relief. Drugstore shelves are filled with many pain remedies. Each one is advertised to be better and faster acting than the others. But nearly all nonprescription pain relievers rely on aspirin, acetaminophen, or ibuprofen for pain relief.
