PRECAUTIONS:
Prior to administration of Selarid, dogs should be tested for existing heartworm infections. At the discretion of the veterinarian, infected dogs should be treated to remove adult heartworms. Selarid is not effective against adult D. immitis and, while the number of circulating microfilariae may decrease following treatment, Selarid is not effective for microfilariae clearance.
Hypersensitivity reactions have not been observed in dogs with patent heartworm infections administered three times the recommended dose of selamectin solution. Higher doses were not tested.
