Abstract
BACKGROUND: Doses of flea and tick medication acquired by dog owners over a 12 month period were determined from veterinary hospital transaction records in Spain. The number of months of flea and tick protection potentially obtained by dog owners prescribed fluralaner, a flea and tick medication with a 12 week re-dosing interval, was compared with months of flea and tick protection obtained by dog owners prescribed monthly oral or spot-on products. Prior studies in human and veterinary medicine have suggested that longer-acting medications benefit patients by providing improved adherence to provider recommendations. RESULTS: Dog owners took home, on average, significantly more months of protection when they obtained the 12 week duration product fluralaner (4.3 months) than they did when they obtained other flea and tick products providing 1 month of protection [3.24 months (oral), 2.9 months (spot-on)]. Many dog owners (46-64%) obtained only one dose of flea and tick product each year, regardless of the duration of protection offered by the product. Significantly more dog owners obtained 7-12 months of protection when they were prescribed fluralaner (15.7%) by their veterinarians compared with dog owners prescribed monthly flea and tick products [6.8% (oral), 8.3% (spot-on)]. CONCLUSION: Veterinary prescription of fluralaner delivers more months of potential flea and tick protection as shown by dog owner acquisition of flea and tick medication. The use of a longer-acting medication requires the administration of fewer doses and may translate into better adherence to veterinary ectoparasite control recommendations.
