To start, give one shot IM (intramuscularly as directed) every 4 days for 4 doses. This is the “loading dose” period. After the loading dose, most horses and/or dogs can be switched to a maintenance dose of once per month. Sport horses used in heavy competition can benefit from more frequent use of Movex, as often as every week for top-level performance. A product insert with detailed dosing instructions comes in every box of Movex.
