4 doctors agree

In brief: Yes

There are now 4 types of histamine receptors.
Zantac (ranitidine) acts on the h2 receptor resulting in blocking stomach acid thereby treating heartburn. Allergies are treated with h1 blocking type medications including claritin, (loratadine) zyrtec and allegra. Some medications have both actions to block both h1 and h2 receptor. For anaphylaxis, zantac can be added for it's effect on blood vessels.
