Consumer information for this interaction is not currently available.
GENERALLY AVOID: Coadministration with moderate inhibitors of CYP450 3A4 may significantly increase the plasma concentrations of naloxegol, which is primarily metabolized by the isoenzyme. When a single 25 mg dose of naloxegol was administered during multiple dosing of 240 mg once daily extended-release diltiazem, a moderate CYP450 3A4 inhibitor, naloxegol peak plasma concentration (Cmax) and systemic exposure (AUC) increased by approximately 2.9- and 3.4-fold, respectively. Increased exposure to naloxegol may precipitate opioid withdrawal symptoms such as hyperhidrosis, lacrimation, rhinorrhea, chills, diarrhea, abdominal pain, anxiety, insomnia, irritability, restlessness, and yawning.
MANAGEMENT: Concomitant use of naloxegol with moderate CYP450 3A4 inhibitors should generally be avoided. If coadministration is required, the dosage of naloxegol should be reduced to 12.5 mg once daily and the patient closely monitored for opioid withdrawal symptoms.

Drug and food interactions
naloxegol food
Applies to: naloxegol
Do not consume grapefruit or grapefruit juice during treatment with naloxegol. Grapefruit juice can significantly increase the blood levels of naloxegol. You may be more likely to experience side effects and withdrawal symptoms such as sweating, tearing, runny nose, chills, diarrhea, abdominal pain, anxiety, insomnia, irritability, restlessness, and yawning. Taking naloxegol with food can also increase its absorption into the blood stream. Therefore, you should take it on an empty stomach at least 1 hour before or 2 hours after a meal. Talk to your doctor or pharmacist if you have questions on how to take this or other medications you are prescribed. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.
