This report displays the potential drug interactions for the following 2 drugs:
- Promethazine with Dextromethorphan (dextromethorphan/promethazine)
- zuranolone
Interactions between your drugs
dextromethorphan promethazine
Applies to: Promethazine with Dextromethorphan (dextromethorphan / promethazine) and Promethazine with Dextromethorphan (dextromethorphan / promethazine)
Using dextromethorphan together with promethazine may increase side effects such as dizziness, drowsiness, confusion, and difficulty concentrating. Some people, especially the elderly, may also experience impairment in thinking, judgment, and motor coordination. You should avoid or limit the use of alcohol while being treated with these medications. Also avoid activities requiring mental alertness such as driving or operating hazardous machinery until you know how the medications affect you. Talk to your doctor if you have any questions or concerns. 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.
dextromethorphan zuranolone
Applies to: Promethazine with Dextromethorphan (dextromethorphan / promethazine) and zuranolone
Consumer information for this interaction is not currently available.
GENERALLY AVOID: Coadministration with central nervous system (CNS) depressants (e.g., alcohol, benzodiazepines, opioids) or antidepressants may enhance the sedative effect of zuranolone and increase the likelihood or severity of sedation-related adverse reactions. Zuranolone may cause CNS depressant effects such as somnolence, confusion, dizziness, and gait disturbance. In clinical trials, somnolence, dizziness, or confusion were reported at a higher percentage in patients treated with zuranolone compared to placebo which required a dosage reduction of zuranolone, treatment interruption, or cessation. One clinical study reported somnolence in 36% of patients treated with 50 mg zuranolone compared to 6% of patients treated with placebo.
MANAGEMENT: Concomitant use of zuranolone with CNS depressants should generally be avoided. Caution and close monitoring of CNS depressant effects is recommended if concomitant use of zuranolone with CNS depressants, antidepressants, or other agents that can cause sedation is required. If coadministration with another CNS depressant is considered unavoidable or if the patient experiences CNS depressant adverse effects within the 14 days treatment course, a dose reduction to 40 mg once daily for the remainder of the course is recommended. Patients should also be cautioned against driving, operating machinery, or engaging in potentially hazardous activities requiring mental alertness and motor coordination until at least 12 hours after administration of zuranolone.

Drug and food interactions
dextromethorphan food
Applies to: Promethazine with Dextromethorphan (dextromethorphan / promethazine)
Alcohol can increase the nervous system side effects of dextromethorphan such as dizziness, drowsiness, and difficulty concentrating. Some people may also experience impairment in thinking and judgment. You should avoid or limit the use of alcohol while being treated with dextromethorphan. Do not use more than the recommended dose of dextromethorphan, and avoid activities requiring mental alertness such as driving or operating hazardous machinery until you know how the medication affects you. Talk to your doctor or pharmacist if you have any questions or concerns.
zuranolone food
Applies to: zuranolone
Consumer information for this interaction is not currently available.
ADJUST DOSING INTERVAL: Food enhances the oral bioavailability of zuranolone. When administered with a low-fat meal (e.g., 400 to 500 calories, 25% fat), zuranolone peak plasma concentration (Cmax) and systemic exposure (AUC) increased by 3.5- and 1.8-fold, respectively, compared to administration under fasted conditions. Zuranolone was administered with food in the premarketing study population. The efficacy of zuranolone when administered in the fasted state is unknown.
GENERALLY AVOID: Concomitant use of zuranolone with central nervous system (CNS) depressants, including alcohol, may potentiate adverse effects such as somnolence, confusion, dizziness, and gait disturbance.
MANAGEMENT: Zuranolone must be administered with fat-containing food (e.g., 400 to 1,000 calories, 25% to 50% fat) according to the manufacturer. Patients should also be advised to avoid or limit consumption of alcohol and to avoid activities requiring mental alertness such as driving or operating hazardous machinery until at least 12 hours after administration of zuranolone.
