Q. Our 3 - 4 lb chihuahua ingested approximately half of a 200mg acyclovir capsule. Should he be OK?

Answered By

A. Acyclovir is generally not considered to be highly toxic, but in some cases it can cause severe renal damage and other symptoms such as: Anorexia, Diarrhea, Dullness, Mydriasis, Polydipsia, Polyuria, Tachycardia, Trembling, Tremor, Vomiting or regurgitation

I would recommend taking him to the vet ASAP in order to induce vomiting if it happened in the last couple hours.
