Selamectin

Why has my veterinarian prescribed this medicine?

Selamectin is used for control of internal and external parasites. Your veterinarian may prescribe selamectin for treatment of roundworms, heartworm prevention, flea infestation, flea allergy dermatitis, mange in dogs, or ear mites in cats. Your veterinarian may also prescribe it for other ectoparasites.

How does this medicine work?

Selamectin interferes with parasite nerve transmission at the level of the post-synaptic membrane, resulting in paralysis and death.

Potential side effects
