Generic versions

Both hydrocodone oral forms and oxycodone oral tablets are generic medications.

A generic medication is an identical copy of the active ingredient in a brand-name medication. (An active ingredient is what makes a medication work.) 

Hydrocodone comes in a brand-name version called Hysingla ER. Oxycodone comes in a brand-name version called Roxicodone. And Oxycontin is the brand-name version of Oxycodone-ER*.

Generics usually cost less than brand-name drugs. And they’re thought to be as safe and effective as the brand-name version.

* Note that ER means extended release. Extended release means the drug is slowly released into your body over a long period of time.

Questions about hydrocodone oral forms and oxycodone oral tablets

Below, you’ll find answers to some common questions about hydrocodone oral forms and oxycodone oral tablets.

How do hydrocodone and oxycodone compare with other medications for pain, such as Dilaudid?

Hydrocodone, oxycodone, and Dilaudid are all opioid medications. Because of this, they are very similar. These medications are prescribed to treat severe pain that doesn’t respond to other treatments. They cause similar severe side effects, and all have several boxed warnings. Each medication has a risk of misuse, addiction, and abuse. (To learn more about these warnings, see the “Warnings” section in this article. The warnings discussed for hydrocodone and oxycodone also apply to Dilaudid.)

One key difference is that Dilaudid is available in an injectable form and an oral form. Hydrocodone and oxycodone are only available in oral forms. In some cases, Dilaudid injection would be prescribed instead of hydrocodone or oxycodone. For example, if you are in the hospital with severe pain and can’t take medications by mouth, you’ll likely be prescribed Dilaudid injection.

Talk with your doctor or pharmacist if you’d like to learn more about how these medications compare.

Between hydrocodone and oxycodone, is one a better treatment for pain?

Doctors may prescribe either hydrocodone oral forms or oxycodone oral tablets to treat severe pain. In studies, hydrocodone oral forms and oxycodone oral tablets were both effective for this purpose.

That said, these medications differ in a few ways. For example, they:

  • Come in different forms: Oxycodone is available in both an immediate-release and extended-release form. Hydrocodone only comes in extended-release forms. (Extended release means that the drug is slowly released into your body over time.)
  • Are used in different age groups: Extended-release oxycodone may be prescribed to children over ages 11 years in certain cases. Hydrocodone is not approved for use in children of any age.

Keep in mind that your results from taking hydrocodone oral forms or oxycodone oral tablets may differ from those seen in studies.

Your doctor can help determine whether one option is better for your condition. They’ll recommend this based on your specific needs and health factors.

Talk with your doctor if you’d like to learn more about which drug is right for you.

Warnings for hydrocodone oral forms and oxycodone oral tablets

Some medications may not be recommended for you if you have certain factors affecting your health. These are referred to as a drug’s warnings.

Some people should not take hydrocodone oral forms or oxycodone oral tablets, and others should take either medication with caution.

Warnings for hydrocodone oral forms and oxycodone oral tablets are summarized below. Before taking either medication, talk with your doctor about your health conditions, past surgeries, and any medications you take. Your doctor can recommend whether either drug is safe for you.

Boxed warnings for hydrocodone and oxycodone

Hydrocodone oral forms and oxycodone oral tablets have boxed warnings about numerous risks. Boxed warnings are the most serious warnings from the Food and Drug Administration (FDA).

Because of these risks, there are strict rules and regulations in place for how hydrocodone or oxycodone may be prescribed and dispensed. All opioid medications, including hydrocodone and oxycodone, have a risk evaluation and mitigation strategy (REMS) program due to these risks. Your doctor and pharmacist can tell you more about the REMS program and what it entails if you’re prescribed hydrocodone or oxycodone.

To learn more about these warnings, read below. You can also talk with your doctor or pharmacist.

Risk of misuse and addiction: With misuse, a drug is taken in a manner other than how it’s prescribed. With addiction, you continue taking a drug despite it causing harmful outcomes. Your doctor will closely monitor you for symptoms of misuse or addiction during treatment. They may prescribe a treatment other than hydrocodone or oxycodone if you have opioid use disorder or have experienced it in the past.

Risk of respiratory depression: With respiratory depression, you experience slow, shallow breathing. This is a serious, potentially life threatening side effect. Your risk of respiratory depression is higher if you have a lung or breathing condition, such as asthma or chronic obstructive pulmonary disease. Call 911 right away or seek emergency medical help if you have symptoms of respiratory depression, including difficulty breathing or bluish-colored lips or extremities.

Risk of accidental ingestion: Accidentally taking hydrocodone or oxycodone can cause a fatal drug overdose. This risk is especially high in children, and it can occur with a single accidental dose. Be sure to store your hydrocodone or oxycodone prescription in a secure place where other people cannot access it.

Risk of neonatal opioid withdrawal syndrome: Taking oxycodone or hydrocodone during pregnancy increases the risk of neonatal opioid withdrawal syndrome (NOWS). NOWS can cause a baby to experience opioid withdrawal after birth. If you’re planning a pregnancy or can become pregnant, talk with your doctor before taking this medication. Your doctor may suggest birth control options to use during treatment with oxycodone or hydrocodone.

Risk of serious harm if taken with certain drugs: There are numerous medications that interact with oxycodone or hydrocodone in a manner that can cause serious harm. In rare cases, these interactions can lead to life threatening side effects, including coma. This interaction can be fatal in rare cases. For example, taking hydrocodone or oxycodone with other drugs that cause central nervous system (CNS) depression increases the risk of severe CNS depression. Examples of other medications that can cause CNS depression are benzodiazepines such as alprazolam (Xanax). Before taking oxycodone or hydrocodone, tell your doctor about any other medications you take.
