It might be different in the US, but in Canada, the zantac pills also taste like mint, and so even if they prepare a compound of zantac at the compounding pharmacy by crushing the pills, it still tastes like mint (just like the syrup).
This probably doesn’t apply to you, but I thought I’d post it in case anyone else ever gets a bottle of zantac that doesn’t smell “minty”. Zantac syrup only comes in mint flavour and you can smell it when you open the bottle.
