Lessons Learned from Using Apoquel in Dogs
Apoquel has been more consistently available during the past year affording the opportunity to appreciate where best to consider its use. Apoquel has been effective in managing pruritus in the majority of patients treated with approximately 80% demonstrating excellent response within 48 to 72 hours of treatment with b.i.d. dosing. Some patients will develop a significant degree of pruritus near the end of the 24-hour dosing period when the dose is reduced to once daily.

Approximately 90% of patients respond…
