title: Common reversal agents/antidotes in small animal poisoning.
abstract: Different antidotes counteract the effect of a toxicant in several different ways. Antidotes can reverse, decrease, or prevent action of a toxicant. They can also help in achieving stabilization of vital signs, directly or indirectly, and promote excretion of a toxicant. However, overreliance on an antidote can be unrealistic and dangerous. While expectations of rapid recovery from antidotes are usually high, in a real life situation, there are many impediments in achieving this goal. The timing of its use, availability, cost, and sometimes adverse effects from the antidote itself can influence the results and outcome of a case. The majority of toxicants do not have a specific antidote therapy indicated and patients in these cases equally benefit from supportive care. In this chapter, commonly used antidotes and reversal agents in small animals are listed in a table form. The table lists generic name along with brand name of an antidote/reversal agent whenever available, main indications for their use, and provides comments or cautions in their use as needed. After stabilizing the patient and establishing the etiology, the clinicians must review more detailed management of that particular toxicant discussed here or in other references.
