What the AI-written analysis says
Fluoxetine is an SSRI used for depression and anxiety, while melatonin is commonly used for sleep regulation. Combining these may lead to increased sedation and potential serotonin-related effects, although significant interactions are not well-documented. Caution is advised, especially regarding timing and dosage.
Fluoxetine is a prescription medication. This page describes publicly documented interactions — it can't see your dose, your other prescriptions, or your labs. Discuss any supplement with the prescriber or pharmacist who manages this medication before combining.
