Does melatonin reduce effectiveness of lorazepam?

There is currently limited research on the interaction between melatonin and lorazepam. While melatonin is generally considered safe and may enhance sleep, it does not directly reduce the effectiveness of lorazepam, a benzodiazepine used for anxiety and sleep disorders. However, combining them could lead to increased sedation or other side effects. It's advisable to consult a healthcare professional before combining these medications.
