What is Tylenol W/codeine No.4 Used For?
Tylenol W/codeine No.4 is a combination of a narcotic (codeine) and a non-narcotic (acetaminophen) used to relieve mild to moderate pain. Codeine works by binding to opioid receptors in the brain and spinal cord, and acetaminophen decreases the formation of prostaglandins, therefore relieving pain. How To Use Tylenol W/codeine No.4 Take Tylenol W/codeine No.4 by mouth, as directed by your doctor. You may take Tylenol W/codeine No.4 with or without food. If you have nausea, you may take Tylenol W/codeine No.4 with food, although doing so may decrease its effectiveness. Consult your doctor or pharmacist about alternatives for decreasing nausea (e.g., antihistamines, lying down for 1-2 hours with minimal head movement). The dosage is based on your medical condition and response to therapy. Pain medications work best in relieving pain before it becomes severe. Once the pain becomes intense, the medication is not as effective in relieving it. Use Tylenol W/codeine No.4 exactly as prescribed
