Provided herein are methods for making targeted therapeutics that target soluble agents such as toxins, venoms, and factors that alter physiological biopathways as well as methods of using such therapeutics to treat patients or patient populations to reduce, eliminate, or inactivate, detrimental soluble agents that such patients or patient populations have been exposed to. In several embodiments the targeted therapeutics comprise a portion that interacts with a soluble agent of interest and a second portion that interacts with a subjects immune system, which enables treatment of a patient for exposure to the soluble agent.
