https://www.forhims.com/blog/melatonin-zoloft-can-you-take-together ~ Yes, you can use melatonin and Zoloft together. Zoloft (sertraline) and other SSRIs can cause insomnia, which means it wouldn’t be unusual for people prescribed Zoloft to consider sleep aids such as melatonin.

Currently, there isn’t very much research on the effects of melatonin and Zoloft together. While there are no reported drug interactions between melatonin and Zoloft, melatonin may make certain antidepressants less effective.

Because of this, it’s best to talk to your healthcare provider before using melatonin and Zoloft at the same time. They’ll be able to tell you about potential safety risks and offer personalized help to make sure that you stay safe while using your medication.

MODERATE Using sertraline together with melatonin 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. ~Drugs.com/interactions-check.pfp

You should probably ask a doctor about it, but to me it seems reletively fine.

Edit: another website states there is no known interaction between the 2, but that's because it remains mostly untested.

Google says their are 307 drugs that are known to react with it. I'll check if zoloft/setraline is one of them

Ohhh okay
Well, do you know if if affects my current medication? I take uhhh setraline/zoloft (for depression) I take 75mg I think

BTW half a milligram is the most you should take, anything more is not helpfull and can make it harder to sleep without melatonin. Most stuff I've seen is 3 to 5 milligrams, so just cut it up if it's the only option.
Also I can confirm I have had some banger dreams with it.
