quick H2-blocker reference

17 Apr

quick-reference chart put together for your use in a pinch.  I frequently found myself double-checking some of the generic/trade name crossover, and the IV/PO first-dosing at times, so figured this might be helpful for others as well.  Here it is, as a chart and photo.




Generic Name Cimetidine Ranitidine Famotidine Nizatidine
Brand Name Tagamet Zantac Pepcid Axid
equivalent dosing (left-to-right)
PO (avg dose) 400mg 150mg 20mg 150mg
PO (big dose) 800mg 300mg 40mg 300mg
IV 300mg IV 50mg IV 20mg IV
