Vetsulin Critical Need Program Ending

I received a letter from Intervet/Schering-Plough Animal health today stating that the critical need program is ending.  I immediately called my veterarian in somewhat of a panic.  We have been avoiding transitioning Zeke to another insulin because he has done so well on the Vetsulin and because he is 14 years old.  It would be so much easier to let him finish his life on the Vetsulin.   So I asked her staff to order the maximum amount of Vetsulin that I can order at one time which is 6 bottles.

The letter reads as follows:

Dear Vetsulin Customer,

You are receiving this letter because our records indicate you have one or more pets participating in the Vetsuiln critical-need program (CNP).  As you know, we alerted you in late 2009 that the product had not met its stability specifications and may have varying amounts of crystalline zinc insulin in the formulation.

We must advise you that because of a manufacturing issue unrelated to the stability oissue referred to abovv, Intervet/Schering-Plough Animal Health is discontinuing the Vetsulin CNP as of Feb. 7, 2011.  However, we will continue to provide Vetsulin for the CNP until our current supply in the U.S. is exhausted - we anticipate being able to fulfill order through February 2011.

This difficult decision is being made because quality tests showed the sterility of the most recent batch of Vetsulin manufacturered for the CNP may be compromised by bacterial contamination.  This batch of Vetsulin has not been released.  While the company is still investigaging the quality issue, aditional batches are not being manufactured at this time. We, therefore, cannot supply the program and it must be discontinued.

We are aware of no evidence that the Vetsulin currently on the market and being unsed under the Critical Need Program is affected.  No adverse events consistent with potential bacterial contaminiation in catas and dogs receiving Vetsulin have been reported under the current program.  We sincerely regret any difficulties this causes and strongly recommend you contact your veterinarian as soon as possible to transition your pet to another insulin product.  Your veterinarian has been made aware of this issue as well.

We sincerely apologze for the need to discontinue the Vetsulin CNP but wanted to provide you with as much advance notice as possible.

As always, Intervet/Schering-Plough Animal Health is concerned for the well-being and health of animsals of all species and the people who care for them.

I don't know if the Caninsulin will also be discontinued so I will be placing a call to the Canadian pharmacies where I have previously purchased Caninsulin in the past.   At the AskAVet website I came across this article about Caninsulin.

My vet and I decided that I should stockpile as much as I am comfortable with and if Zeke should outlive the supply then we will deal with transitioning him to another insulin.
