Side Effects

Fenbendazole may cause the release of antigens by the dying parasites. This phenomenon may result in either a local or systemic hypersensitive reaction.


Should a massive overdose occur, treat symptomatically and supportively   


Reports indicate the combination of ivermectin and the silver nightshade plant results in a severe toxic reaction in horses.
