Buy Percocet 5-325 mg online is a prescription pain reliever that combines oxycodone, an opioid, with acetaminophen (Tylenol). It is used to manage moderate to severe pain when other treatments are not sufficient. Oxycodone works by changing how the brain and nervous system respond to pain, while acetaminophen helps reduce pain and fever. Common side effects include drowsiness, dizziness, constipation, nausea, and headache. Because it contains an opioid, Percocet carries risks of dependence, misuse, addiction, and overdose, so it should only be taken as prescribed.
