FAQ-Answers

Q1. What is Leventa?
A: Leventa is a readily accepted, easily administered, small-volume liquid formulation of levothyroxine sodium. It provides the thyroxine needed by dogs with hypothyroidism, plus the convenience dog owners want. Given once daily, Leventa is an effective, convenient alternative to oral tablets, which sometimes have to be administered twice daily for treatment of canine hypothyroidism.

Q2. What is the recommended dose rate for Leventa?
A: At treatment initiation, the recommended dose rate is 20 µg/kg body weight once daily. Dogs should be reevaluated every 4 weeks by monitoring total thyroxine (tT4) serum levels 4-6 hours post-treatment. Once the dosage sufficient to maintain the dog in a euthyroid state has been determined, serum tT4 levels should be checked every 6 months, and the dosage adjusted as necessary to tailor therapy to each patient. The usual maintenance dosage of Leventa is 20 µg/kg body weight once daily.

Q3. How is dosing accuracy assured?
A: An oral dosing syringe, calibrated in 0.01-mL increments, is enclosed with each 30-mL bottle of Leventa. This facilitates precise titration of each patient’s therapy for optimal results.

Q4. Does Leventa offer any advantages over current canine hypothyroidism treatment options?
A: The small-volume liquid formulation of levothyroxine sodium offers important advantages. Because it is a readily accepted liquid it can be dosed directly into the dog’s mouth or mixed with food. Leventa requires administration just once a day — another plus for busy owners. Finally, Leventa’s liquid formulation facilitates precise dosing and flexibility. All this adds up to optimal client compliance and positive treatment outcomes.

Q5. Aren’t oral tablets easier to stock?
A: Clinics that stock Leventa can replace the multiple sizes of tablets that must be stocked with single 30 mL bottles of Leventa. Dosage modifications can be made without having to dispense new tablet sizes, saving staff time while minimizing client cost and potential confusion. However, even if veterinarians find it necessary to stock tablets along with Leventa, the benefit of offering a formulation choice can be important to clients.
