Thanks for pointing this out. I forgot where I read about using caution with melatonin if on Eliquis (a popular anticoagulant) but recall that I did. I found this one citation now:

If our health histories become more complicated requiring prescriptions, it's wise to check for possible drug-drug AND drug-food interactions. For example, I learned that while taking kisqali for breast cancer, I need to be careful with pomegranates. I've known about grapefruit and grapefruit juice but pomegranates was unexpected.
