Both Hydrocodone vs Oxycodone are powerful prescription opioid painkillers commonly prescribed for moderate to severe pain. While they share many similarities, understanding their differences can help you and your healthcare provider make the best choice for your specific situation.
Potency and Strength Hydrocodone vs Oxycodone
Oxycodone is approximately 50% stronger than hydrocodone. This means that a lower dose of oxycodone may provide similar pain relief to a higher dose of hydrocodone. Both medications are classified as Schedule II controlled substances by the DEA, indicating their high potential for abuse.

Effectiveness for Pain Relief
Despite the difference in potency, studies have shown that when combined with acetaminophen (Tylenol), both medications provide similar pain relief:
- A clinical study comparing Hydrocodone vs Oxycodone for treating acute pain from fractures found no significant difference in pain relief at 30 and 60 minutes after administration.
- Some research indicates that hydrocodone with acetaminophen can be just as effective at treating pain as oxycodone with acetaminophen, despite oxycodone’s greater potency.
Duration of Action
Both medications are available in immediate-release and extended-release formulations:
- Immediate-release forms: Both have similar half-lives
- Extended-release forms: Hydrocodone ER has a longer half-life (7-9 hours) compared to oxycodone ER (4.5-5.6 hours)
Common Side Effects
Both medications share similar side effects typical of opioids, including:
- Constipation
- Nausea or vomiting
- Sedation and drowsiness
- Dizziness
- Lightheadedness
- Itching
- Headache
- Dry mouth
- Sweating
- Weakness
However, one notable difference is that hydrocodone appears to cause a higher incidence of constipation compared to oxycodone.
Risk of Dependence and Long-Term Use
Recent research has revealed an important difference between these medications regarding long-term use:
- Patients prescribed hydrocodone for acute back pain were significantly more likely to transition to long-term opioid use (12%) compared to those prescribed oxycodone (2%).
- Among patients who received more than one prescription, the difference was even more pronounced: 23% of hydrocodone users transitioned to long-term use versus only 5% of oxycodone users.
This suggests that despite similar effectiveness for pain relief, hydrocodone may carry a higher risk of developing long-term dependence.
Addiction Potential
Both medications carry significant risks of addiction and dependence. Signs of opioid addiction include:
- Taking more than prescribed or for longer than intended
- Unsuccessful attempts to cut back
- Spending excessive time obtaining, using, or recovering from the drug
- Experiencing cravings
- Neglecting responsibilities due to opioid use
- Continued use despite negative consequences
- Developing tolerance (needing higher doses)
- Experiencing withdrawal symptoms when stopping
Which One Might Be Right for You?
The choice between Hydrocodone vs Oxycodone should be made with your healthcare provider based on:
- Pain severity: Oxycodone may be preferred for more severe pain due to its higher potency
- Previous response: How you’ve responded to either medication in the past
- Side effect sensitivity: If constipation is a significant concern, oxycodone might be preferable
- Risk factors for dependence: Given the higher risk of long-term use with hydrocodone, patients with risk factors for dependence might be better suited for oxycodone
- Duration needs: For longer-lasting relief, extended-release formulations should be considered
Safety Guidelines
When taking either medication:
- Take exactly as prescribed, never more
- Do not combine with alcohol or other central nervous system depressants
- Store securely away from others, especially children
- Never share your prescription with anyone
- Discuss a tapering plan with your doctor if you’ve been taking the medication for more than a few days
- Be aware that extended-release formulations should not be used for acute pain
Medical Monitoring
Healthcare providers should:
- Monitor patients closely, especially when initiating therapy or increasing doses
- Consider urine or serum drug testing before starting therapy and periodically thereafter
- Re-evaluate the risks and benefits of continued therapy at least every 3 months
- Use caution when daily dosage exceeds 50 morphine milligram equivalents (MME)
Conclusion
Hydrocodone vs Oxycodone can be effective options for managing moderate to severe pain. While oxycodone is more potent, both medications appear to provide similar pain relief when combined with acetaminophen. The most significant difference may be in the risk of developing long-term use, which appears higher with hydrocodone.
Always discuss your complete medical history, other medications, and risk factors with your healthcare provider to determine which option is safest and most appropriate for your specific situation. Remember that all opioid medications carry risks of side effects, dependence, and addiction, even when taken as prescribed.
