Yes, you can take Asentra (sertraline) in the morning and melatonin in the evening.

Asentra is an antidepressant that acts at the level of neurotransmitters and has no known interactions with melatonin. Melatonin is relatively safe and helps regulate sleep rhythms.

I encourage you to inform your attending physician about all the medications and dietary supplements you use, which will allow you to choose safe and effective pharmacotherapy. Only a doctor can assess whether the combination of these drugs is safe and appropriate for your current clinical condition. If you are unable to consult your doctor, you can use the teleconsultation here:
