Safety of concurrent treatment of dogs with fluralaner (Bravecto™) and milbemycin oxime-praziquantel.

BACKGROUND

Fluralaner (Bravecto™; Merck/MSD Animal Health) is a novel systemic ectoparasiticide for dogs providing long-acting flea and tick control after a single oral dose. Milbemycin oxime and praziquantel are routinely used to control Dirofilaria immitis and intestinal worm infections in dogs. The safety of concurrent use of fluralaner and a commercially available milbemycin oxime plus praziquantel combination tablet, in particular with regard to gastrointestinal symptoms, was investigated using oral doses at or above the maximum recommended rates.

FINDINGS: Some minor and transient clinical findings were observed during the study period; however, none of these was considered to be related to concurrent treatment with fluralaner and milbemycin oxime plus praziquantel, or to the use of either product alone.

CONCLUSIONS

Concurrent treatment with fluralaner, milbemycin oxime and praziquantel is well tolerated in dogs.
