Hydrocodone vs. Oxycodone

Last Updated: May 16, 2023

Editorial Policy | Research Policy

Hydrocodone and oxycodone are similar opioids frequently prescribed to treat pain, but the drugs differ in their available dosage, forms and strengths.

Hydrocodone and oxycodone are opioids frequently prescribed to treat pain. Hydrocodone is usually combined with acetaminophen to make products like Vicodin, and in 2019 this combination was the most common pain-relieving therapy prescribed in the U.S., with more than 30 million prescriptions. Oxycodone is also a common pain reliever, with more than 14 million prescriptions in 2019 and an additional 11 million prescriptions when combined with acetaminophen to make drugs like Percocet. However, despite their similarities, the drugs have important differences.

Overcome addiction with evidence-based, expert care.

Is Hydrocodone the Same as Oxycodone?

Hydrocodone is not the same drug as oxycodone. Although they are both semisynthetic opioids and Schedule II controlled substances, they differ in many ways. This includes their strength and available dosage forms.

What Is Hydrocodone (Vicodin)?

Hydrocodone is an opioid and Schedule II controlled substance. It is usually sold combined with other drugs like acetaminophen and is the most common prescription analgesic in the U.S.

Hydrocodone is available on its own in a long-acting dosage form called Hysingla ER. When combined with acetaminophen, it is available as a generic drug and under the brand names:

  • Lortab
  • Verdrocet
  • Xodol

Previously, hydrocodone/acetaminophen was also available under the brand names Vicodin, Lorcet and Norco, but these have been discontinued, although some people still use the names conversationally to refer to the drug.

What Is Oxycodone (Percocet)?

Oxycodone is an opioid and Schedule II controlled substance. It is one of the most common analgesics in the U.S., both alone and when prescribed with acetaminophen.

Oxycodone is sold on its own under several brand names in long-acting and short-acting dosage forms. These include:

  • OxyContin
  • Oxaydo
  • Roxicodone
  • RoxyBond
  • Xtampza ER

The drug is also sold combined with acetaminophen available under brand names like:

  • Percocet
  • Endocet
  • Nalocet
  • Prolate

The combination was previously available under the brand name Primlev, which has been discontinued.

Vicodin vs. Percocet

Hydrocodone/acetaminophen (Vicodin) and oxycodone/acetaminophen (Percocet) are similar drugs in many ways. After all, they are both opioids sold combined with acetaminophen. However, for all their similarities, the drugs also have some key differences.

Drug Class/Scheduling

Both hydrocodone/acetaminophen and oxycodone/acetaminophen are Schedule II controlled substances. This means they can put a person at high risk of abuse, addiction and dependence. For this reason, the drugs should only be taken as prescribed by your doctor and for the shortest duration possible.


The main difference between hydrocodone and oxycodone is their strength. Oxycodone is the stronger of the two drugs and about 1.5 timesas potent as hydrocodone. In other words, 30 mg of hydrocodone is equivalent to 20 mg of oxycodone.


Hydrocodone on its own is only available as oral tablets. However, when combined with acetaminophen, it is available as oral tablets and as an oral solution.

In contrast, oxycodone, both alone and combined with acetaminophen, is available as oral tablets and liquids.


The doses of hydrocodone/acetaminophen and oxycodone/acetaminophen are similar:

Hydrocodone/acetaminophen dosesOxycodone/acetaminophen doses
5 mg hydrocodone/325 mg acetaminophen2.5 mg oxycodone/300 mg acetaminophen
7.5 mg hydrocodone/300 mg acetaminophen2.5 mg oxycodone/325 mg acetaminophen
7.5 mg hydrocodone/325 mg acetaminophen5 mg oxycodone/300 mg acetaminophen
10 mg hydrocodone/300 mg acetaminophen5 mg oxycodone/325 mg acetaminophen
10 mg hydrocodone/325 mg acetaminophen7.5 mg oxycodone/300 mg acetaminophen
7.5 mg oxycodone/325 mg acetaminophen
10 mg oxycodone/300 mg acetaminophen
10 mg oxycodone/325 mg acetaminophen

Side Effects

Hydrocodone/acetaminophen and oxycodone/acetaminophen have similar side effects. These include:

  • Light-headedness or dizziness
  • Sedation
  • Nausea and vomiting
  • Constipation

Drug Interactions

As central nervous system depressants, hydrocodone/acetaminophen and oxycodone/acetaminophen have similar drug interactions. They both carry boxed warnings for drug interactions including:

  • Use with other acetaminophen products, which can lead to liver damage.
  • Use with other central nervous system depressants, especially benzodiazepines, which can lead to overdose. In 2020, 16% of opioid overdose deaths involved benzos.

Can You Take Oxycodone and Hydrocodone Together?

Generally, you should not take oxycodone and hydrocodone together; they are usually not prescribed together. This is because oxycodone is stronger than hydrocodone, so a person whose pain requires oxycodone is unlikely to benefit from the much-weaker hydrocodone.

However, there are exceptions. For example, a person may be prescribed a long-acting oxycodone product like OxyContin and a short-acting hydrocodone product like Norco for breakthrough pain.

Because the drugs are both opioids, you should never take them together unless specifically told to by your doctor. The dangers of mixing oxycodone and hydrocodone include liver toxicity from the acetaminophen components, increased side effects and overdose, which can be fatal.
