moderate Known Drug Interaction
Examples: Rifampin, carbamazepine, phenytoin Benzodiazepines and Other Central Nervous System (CNS) Depressants Clinical Impact: Due to additive pharmacologic effect, the concomitant use of benzodiazepines or other CNS depressants, including alcohol, can increase the risk of hypotension, respiratory depression, profound sedation, coma, and death [see Warnings and Precautions (5.3)] .

It is important to use rifampin only for infections that are proven or strongly suspected to be caused by bacteria. This helps to prevent bacteria from becoming resistant to the medicine.
Oxycodone works by changing how your brain and nervous system respond to pain. It attaches to certain receptors in the brain. This helps to block pain signals and reduce pain.

Oxycodone can cause serious, life-threatening risks: * Addiction, abuse, and misuse can lead to overdose and death. Your doctor will check your risk before prescribing and during treatment. * It can cause very slow or stopped breathing, especially when you start taking it or after a dose increase. * If a child accidentally takes even one dose, it can cause a fatal overdose. * Taking it with benzodiazepines (like Xanax) or other depressants (like alcohol) can cause sleepiness, slowed breathing, coma, and death. * Using oxycodone for a long time during pregnancy can cause withdrawal symptoms in the newborn. * Taking oxycodone with certain other medicines can cause dangerous side effects.
Rifampin can cause liver problems. Tell your doctor right away if you have yellowing of the skin or eyes, dark urine, or stomach pain. Rifampin can also cause blood problems. Tell your doctor if you have unusual bleeding or bruising.
Using oxycodone for a long time during pregnancy can cause withdrawal symptoms in the baby after birth. Talk to your doctor about the risks if you are pregnant or plan to become pregnant. Oxycodone is not recommended during labor, as it can cause breathing problems in the newborn.

How to Read This oxycodone vs rifampin Comparison
oxycodone is classified in the Opioid Analgesic drug class, while rifampin sits within the Rifamycin Antibiotic class. Drugs from different classes work through distinct mechanisms, so a head-to-head comparison illustrates trade-offs rather than equivalence. Both drugs are prescription-only, so a licensed provider must authorize use.
Adverse event totals above are pulled from the FDA's Adverse Event Reporting System (FAERS). For these top-ranked reactions alone, oxycodone has 108,821 submissions while rifampin has 3,416. Those figures reflect cumulative reporting volume, not per-patient risk, so older, widely dispensed drugs typically look worse on count alone. These two drugs have a known moderate interaction flagged in FDA labeling, attributed to combining these drugs can cause their effects to stack up, which may lead to a dangerous drop in blood pressure or breathing rate. this additive effect can result in severe sedation or even a coma.. Serious warnings, pregnancy guidance, and contraindications can differ even when indications overlap.
A table cannot represent individual circumstances. Data here is sourced from FDA Structured Product Labels (SPL) and FAERS, both of which update as manufacturers and clinicians submit new information. This registry does not provide medical, treatment, substitution, or medication-change directions for oxycodone or rifampin.
