Hydrocodone vs. Oxycodone: What’s the Difference?

Hydrocodone and oxycodone are two powerful prescription opioids prescribed to manage moderate to severe pain. According to the North Carolina Medical Board, hydrocodone and oxycodone were dispensed to outpatients in North Carolina 38 times more than methadone between 1999 to 2017.

While both medications are effective at relieving pain, they differ in several key areas, including their chemical structure, potency, and how they’re metabolized in the body. Understanding these differences is crucial for patients and healthcare providers to ensure the most appropriate medication is chosen based on the individual’s needs, medical history, and potential side effects.

Forms

Hydrocodone and Oxycodone are both available in multiple forms to suit different patient needs. Hydrocodone is available in oral tablets, capsules, and liquid form. It is most commonly combined with other non-opioid analgesics, such as acetaminophen (Tylenol) or ibuprofen, to boost its pain-relieving effects.

Oxycodone is only available in oral tablets and capsules, including both immediate-release and extended-release formulations. It is prescribed alone or in combination with acetaminophen or aspirin for enhanced effectiveness.

Dosages

Hydrocodone and Oxycodone come in a variety of dosages, with adjustments based on the severity of pain and the patient’s tolerance. Hydrocodone is usually prescribed in dosages of 5 mg, 7.5 mg, and 10 mg per tablet (combined with acetaminophen or ibuprofen).

Oxycodone is available in doses ranging from 5 mg, 10 mg, 15 mg, 20 mg, and up to 80 mg for extended-release forms. Immediate-release forms are generally taken every 4-6 hours, while extended-release tablets are taken every 12 hours.

Potency

Oxycodone is more potent than hydrocodone. Oxycodone provides stronger pain relief at lower doses compared to hydrocodone. Due to its higher potency, oxycodone is more commonly used for severe pain management, while hydrocodone is typically prescribed for moderate pain.

Side Effects

While both hydrocodone and oxycodone share common opioid-related side effects, their severity differs. Common side effects for both include dizziness, drowsiness, nausea, vomiting, constipation, and respiratory depression.

Hydrocodone has a slightly lower risk of severe respiratory depression and euphoria, making it somewhat less risky in terms of side effects compared to oxycodone. Oxycodone, being more potent, causes more pronounced side effects, particularly in higher doses, including a higher risk of sedation, respiratory issues, and constipation. The difference in side effects largely stems from oxycodone’s increased potency and more direct interaction with the brain’s opioid receptors.

Which makes you sleepier, oxycodone or hydrocodone?

Oxycodone makes you sleepier than hydrocodone due to its higher potency. As a stronger opioid, oxycodone causes more pronounced sedation, especially at higher doses or in individuals sensitive to opioids. Hydrocodone, while still sedating, is generally less potent and tends to have a milder sedative effect.

Abuse and Addiction Potential

Both hydrocodone and oxycodone carry a risk of abuse, addiction, and overdose, but oxycodone is considered to have a higher potential for abuse due to its potency. Oxycodone is more commonly abused, particularly in its extended-release form, because it provides a stronger euphoric high, increasing its potential for misuse. 

Hydrocodone is less likely to be abused in its combination forms (e.g., with acetaminophen), as the combination makes it harder to misuse.

What are the differences between Hydrocodone and Oxycodone? 

What are the similarities between Hydrocodone and Oxycodone?

Hydrocodone and oxycodone share several key similarities, primarily in their classification and function as opioid pain relievers. Both are semi-synthetic opioids derived from natural opiates and work by altering how the brain and nervous system respond to pain. They are commonly prescribed for the treatment of moderate to severe pain, such as post-surgical pain or chronic pain conditions. 

Both medications are available in various forms, including tablets, capsules, and liquid, and are combined with other non-opioid pain relievers, such as acetaminophen or ibuprofen, to enhance their pain-relieving effects. Hydrocodone and oxycodone are also associated with similar side effects, including dizziness, drowsiness, nausea, constipation, and the risk of respiratory depression. Both carry a high potential for abuse, addiction, and overdose, leading to their classification as Schedule II controlled substances by the Drug Enforcement Administration (DEA).

Can You Take Oxycodone and Hydrocodone Together?

No, you should not take oxycodone and hydrocodone together without explicit guidance from a healthcare provider. Both medications are opioids, and combining them increases the risk of serious side effects, including respiratory depression, overdose, and death. 

Taking both at the same time leads to a higher level of sedation and potentially dangerous interactions, as both drugs have similar mechanisms of action. Consult a healthcare professional before combining any medications.

Can you get Addicted to Oxycodone?

Yes, you can get addicted to oxycodone. It is a powerful opioid that affects the brain’s reward system, leading to physical and psychological dependence. Even when taken as prescribed, prolonged use results in tolerance, requiring higher doses for the same effect. 

Misuse, such as taking larger amounts or using it without a prescription, increases the risk of oxycodone addiction. From 2000 to 2022, more than 36,000 North Carolinians lost their lives to drug overdoses, with opioids being a major contributor, as per the North Carolina Department of Health and Human Services (NCDHHS).

Can you get Addicted to Hydrocodone?

Yes, you can become addicted to hydrocodone. Hydrocodone is a semi-synthetic opioid classified as a Schedule II controlled substance, indicating a high potential for abuse and dependence. The risk of hydrocodone addiction increases with prolonged use, higher doses, and the presence of other risk factors like a history of substance use disorders.
