Differences between Vicodin- and Percocet
Contents
Comparison of Vicodin and Percocet[edit]
Vicodin and Percocet are combination opioid analgesics used to manage moderate to severe pain. Both medications consist of a primary opioid narcotic mixed with acetaminophen (paracetamol). While they share similar applications and side effects, they differ in their active opioid components and relative potency.
Vicodin is the brand name for the combination of hydrocodone bitartrate and acetaminophen. Percocet is the brand name for the combination of oxycodone hydrochloride and acetaminophen. Both drugs are classified as Schedule II controlled substances by the United States Drug Enforcement Administration (DEA) due to their high potential for abuse and physical dependence.[1]
Comparison table[edit]
| Feature | Vicodin | Percocet |
|---|---|---|
| Primary opioid | Hydrocodone | Oxycodone |
| Non-opioid component | Acetaminophen | Acetaminophen |
| DEA schedule | Schedule II | Schedule II |
| Relative potency | 1.0 (Standard) | Approx. 1.5 times stronger than hydrocodone |
| Common dosage forms | 5 mg / 300 mg; 7.5 mg / 300 mg | 2.5 mg / 325 mg; 5 mg / 325 mg; 10 mg / 325 mg |
| FDA approval year | 1978 (Hydrocodone/APAP) | 1976 (Oxycodone/APAP) |
Pharmacological differences[edit]
The main difference between the two medications is the chemical structure and potency of the opioid component. Oxycodone, the narcotic in Percocet, is a semi-synthetic opioid derived from thebaine. It is generally considered more potent than hydrocodone, which is derived from codeine. Clinical studies suggest that oxycodone is approximately 1.5 times more potent than hydrocodone when administered orally.[2]
In 2014, the U.S. Food and Drug Administration (FDA) implemented changes to the amount of acetaminophen allowed in prescription combination products. Manufacturers are now limited to 325 mg of acetaminophen per dosage unit to reduce the risk of liver toxicity. Both Vicodin and Percocet formulations were updated to comply with these safety standards.[3]
Side effects and risks[edit]
Both medications carry significant risks of respiratory depression, sedation, and constipation. Common side effects include nausea, dizziness, and lightheadedness. Because both drugs contain acetaminophen, patients must avoid taking additional over-the-counter products containing acetaminophen to prevent acute liver failure.
Long-term use of either Vicodin or Percocet can lead to tolerance, where higher doses are required to achieve the same pain-relieving effect. Discontinuation after prolonged use often results in withdrawal symptoms, including muscle aches, anxiety, and insomnia. Both drugs are central to the ongoing opioid crisis in North America, necessitating strict clinical oversight and monitoring via state-level prescription drug monitoring programs (PDMPs).[4][5]
