Why has FDA and Intervet/Schering-Plough Animal Health issued a VETSULIN Alert?
The product has been found to be out of specification in regards to the long term stability of the crystalline, or long acting, component. Specifically, the concentration of the crystalline component is higher than what is outlined in the specifications of the product. Consequently, the amorphous, or short-acting, component may have a lower concentration. This could mean that diabetic patients on VETSULIN may experience a delay in onset of action, a delay in peak activity and an overall extension of the duration of activity.
