Advil Dual Action Back Pain Caplets combine two top selling pain fighting ingredients to fight back pain in two ways: acetaminophen blocks pain signals and ibuprofen targets pain caused by inflammation. Each dose contains 250mg of ibuprofen and 500mg of acetaminophen to quickly relieve tough back pain and provide 8 hours of relief. This pain reliever provides relief from upper back pain, lower back pain, and a wide variety of other aches and pains, including, headache, toothache, muscle pain, and minor aches associated with arthritis. The combination of ibuprofen and acetaminophen in the caplets allows you to take a lower maximum daily dose of each pain medication, while still having 8 hours of powerful relief.
