Abrin is highly toxic, with an estimated human fatal dose of 0.

Effects of abrin poisoning depend on whether abrin was breathed in, swallowed, or injected. The abrin-rRNA attachment inhibits mRNA decoding, leading to extreme reduction in protein synthesis and subsequent cell death. The combination of CRRT and HP is an efficient measure in the treatment of abrin poisoning for which there poiwoning no specific antidote.
