I will be in Cozumel in a few weeks for a short dive trip. My doctor doesn't write prescriptions for OTC cold medicine (I don't need one to purchase Sudafed here, though its purchase is recorded).

I have nothing declarable on the Mexico customs card (e.g. $10K cash)

If I have a 24-ct box of generic pseudoephedrine, original packaging, in my toiletry kit and am red-lighted, is it the conventional wisdom that the worst thing that can happen is that it gets confiscated?

Thank you.
