Ivermectin

Ivermectin

Species: Both

Used monthly for heartworm prevention in dogs and cats; also controls certain intestinal parasites.

Generally safe at labeled doses. Use caution in collies and herding breeds with MDR1 gene mutation at higher doses.

At preventive doses, side effects are rare; occasional lethargy or mild GI upset. Over-sensitivity possible in some herding breeds.

High doses can cause neurologic symptoms (tremors, ataxia, seizures, coma). Immediate veterinary care is necessary in case of significant overdose.

Store at controlled room temperature (20–25°C / 68–77°F); protect from light and moisture. Keep out of reach of children.
