What the FDA labels say about taking them together

Aripiprazole and rifampin

Aripiprazole's FDA label of January 29, 2025 names rifampin in its drug interactions section; the rifampin label PlainMeds reads does not name aripiprazole. The aripiprazole label: “Increase the ABILIFY dosage when administered concomitantly with a strong CYP3A4 inducer.”

These are the labels' own sentences. PlainMeds does not grade interactions; a pharmacist or prescriber can say what they mean for one person's medicines.
