Zantac is a A hitamine 1 blocker your stomach produces histamine1 and it leades to acid build up. Zantac is not the same as benadyl. Benadryl is used for anaphylactic shock Epi pen followed up by 50 mg beadryl.Zantac is not an antihistamine. It reduces the amount of acid produced in the stomach. I suggest obtaining script from family Dr. for a epi pin. This will give time if true allergy to sting emerges. Benadryl is best antihistamine although it is sedating. Do not exceed recommended doses of any meds. (doubling up not good). Speak to doctor,RPh, or RN to explain true anaphylactic symptoms.
my dad does this too for an allergic reaction. Might I also add that taking drugs does not mask symptoms. These really help to counteract reactions.The concoction we use in the ED for stings (with or without anaphalaxis) is Benadryl (an antihistamine), Zantac (also an antihistamine), and an IV steroids (to reduce inflammation). I usually replicate that at home after being stung by taking 50mg of Benedryl, 150mg of Zantac, and rubbing the area of the sting with hydrocortizone cream. I find that this works very well.
