Genuine Bayer Aspirin provides pain relief from headaches, backaches, muscle pain, toothaches, menstrual pain and minor arthritis pain and has for over 100 years. It can also be taken, under a doctor’s supervision, to help reduce the risk of a recurrent heart attack or ischemic stroke. No other leading brand of pain reliever* can do that. Taking Genuine Bayer Aspirin for pain relief does not interfere with the benefits of taking it on a doctor-directed aspirin regimen. Aspirin is not appropriate for everyone, so be sure to talk to your doctor before you begin an aspirin regimen. *Among OTC brands.
