Yes – pets need the immunosuppressants to help stop the cell destruction as soon as possible. Therefore, we recommend that your pet continue with his current medications while receiving the stem cells. Stem cells and medications are not mutually exclusive and can be given at the same time. Your vet will continue to monitor your pet’s case and wean them off their meds as their pcv and other elements of their blood work return to normal. We will consult with your vet as needed.
