Although the H2-receptor blockers are very safe drugs, they are capable of causing thrombocytopenia, a disorder in which there are too few platelets in the blood. This deficiency may cause bleeding problems,
The most common H2-receptor blockers are cimetidine (Tagamet), famotidine (Pepcid), nizatidine (Axid), and ranitidine (Zantac).
There are two types of gastric acid inhibitors, H2-receptor blockers and proton pump inhibitors. H2-receptor blockers are a type of antihistamine.
H2 blockers are mainly used as treatment for people with gastroesophageal diseases who have an excess of stomach acid. These blockers reduce the amount of stomach acid your body produces, making heartburn or acid reflux much less likely.

The three other H2 receptor blockers, famotidine (Pepcid, Pepcid AC), nizatidine (Axid), and ranitidine (Zantac), are similar in their uses.
H2 receptor blockers are used to treat conditions associated with excess amounts of stomach acid, although in some cases they have been replaced by the proton pump inhibitors,
They are not. Alpha blockers are given first because beta blockers without prior alpha blockade can cause a hypertensive crisis.
