It is made from immunoglobulin fragments from sheep that have already been immunized with a digoxin derivative, digoxindicarboxymethoxylamine (DDMA). Its brand names include Digibind (GlaxoSmithKline) and DigiFab (BTG plc). It is used for digoxin toxicity when one of the following is present: Avoid use in hypokalemia as this drug, while reversing the effects of digitalis, will further reduce serum potassium levels and could precipitate dangerous and even fatal cardiac arrhythmias. The patient must be closely monitored for anaphylactic shock, and anyone allergic to sheep protein, papain, bromelain, or papaya extracts (papain is used to cleave the antibody into Fab and Fc fragments) should not use ovine digoxin immune fab. Because it is relatively new, no drug interaction studies have been performed yet.
