What Are Warnings and Precautions for Zuranolone?
Effects of drug abuse
- See “What Are Side Effects Associated with Using Zuranolone?”
- See “What Are Side Effects Associated with Using Zuranolone?”
- Causes driving impairment due to CNS depressant effects
- May cause fetal harm when administered to pregnant women’s
- CNS depressant effects
- CNS depressant effects reported (e.g., somnolence, confusion)
- Patients may be at higher risk of falls
- Other CNS depressants (e.g., alcohol, benzodiazepines, opioids, tricyclic antidepressants) or drugs that increase Zuranolone concentration, may increase the impairment of psychomotor performance or CNS depressant effects such as somnolence, cognitive impairment, and the risk of respiratory depression
- Reduce the risk of CNS depressant effects and/or mitigate CNS depression
- If CNS depressant effects develop, consider dosage reduction or discontinuation
- If use with another CNS depressant is unavoidable, consider dosage reduction
- Reduce dosage in patients taking strong CYP3A4 inhibitors
- Suicidal thoughts and behavior
- In pooled analyses of placebo-controlled trials of long-term administration of antidepressant drugs (SSRIs and other antidepressants), the incidence of suicidal thoughts and behaviors in antidepressant-treated patients aged younger than 24 years was greater than in placebo-treated patients
- Zuranolone does not directly affect monoaminergic systems; because of this and the comparatively low number of exposures to zuranolone, the risk of developing suicidal thoughts and behaviors is unknown
- Consider changing the therapeutic regimen, including discontinuing zuranolone, in patients whose depression becomes worse or who experience emergent suicidal thoughts and behaviors
- Drug interaction overview
- CNS depressants
- Avoid or modify the dose
- Coadministration with CNS depressants (e.g., alcohol, opioids, benzodiazepines) may have additive pharmacological effects and increase the impairment of psychomotor performance or CNS depressant effects
- If unavoidable, consider reducing the zuranolone dose
- CYP3A4 inducers
- CYP3A4 inducers decrease zuranolone systemic exposure, which may reduce efficacy
- Strong CYP3A4 inhibitors
- Modify (reduce) zuranolone dose
- Strong CYP3A4 inhibitors increase zuranolone systemic exposure, which may increase adverse effects
Pregnancy and Lactation
- Based on findings from animal studies, zuranolone may cause fetal harm
- Advise pregnant women of potential risk to a fetus
- Pregnancy exposure registry
- Registry monitors pregnancy outcomes in women exposed to antidepressants during pregnancy
- Clinicians are encouraged to register patients by calling the National Pregnancy Registry for Antidepressants at 1-844-405-6185 or visiting online
- Advise women patients of reproductive potential to use effective contraception during treatment and for 1 week after the final dose

- There are no data on the effects of zuranolone on breastfed infants and limited data regarding the effects on milk production
