🔀 Oxycodone and Acetaminophen with other medicines, food and alcohol
The label says to discuss these with your doctor or pharmacist
- CYP3A4 inhibitors, such as macrolide antibiotics (for example erythromycin), azole antifungals (for example ketoconazole), and protease inhibitors (for example ritonavir), can raise oxycodone levels and increase or prolong opioid effects.
- Stopping a CYP3A4 inhibitor can lower oxycodone levels, which may reduce pain relief or cause withdrawal symptoms.
- CYP3A4 inducers, such as rifampin, carbamazepine, and phenytoin, can lower oxycodone levels and reduce effectiveness or cause withdrawal symptoms.
- Stopping a CYP3A4 inducer can raise oxycodone levels and may cause serious breathing problems.
- Benzodiazepines and other central nervous system depressants can cause profound sedation, slowed breathing, coma, and death.
- Other opioid medicines, street drugs, and alcohol can add to the risk of severe drowsiness and breathing problems.
- The label says to tell your provider about all prescription and over-the-counter medicines, vitamins, and herbal supplements you take.
