For most wounds, once the 12-day Accel-Heal therapy has been completed, the wound continues to progress towards healing. For some of long duration (i.e. over 12 months), for very large wounds, or patients with challenging comorbidities that have weak underlying healing potential, a second treatment with Accel-Heal may be necessary to maintain the wound on a healing trajectory.
A second therapy is appropriate, if there was some response to the first treatment (i.e. pain reduction and/or wound size reduction) but the wound healing subsequently stalls or deteriorates. This can be the case in the event of a wound infection.
In general, it is recommended to wait approximately four weeks, to enable the first therapy to have its full effect, as the wound continues to heal after the therapy has been completed. However, there is no issue in using consecutive treatments if deemed clinically appropriate.
