This practice is called non medical switching. It is like, but not really like, using a generic for a name brand pill.
In this case it is the exact same insulin. Your insurance company has made an economic decision to use the lesser cost.
Here is where it breaks down. Suppose there were two products functionally the same. But not identical in make up. This would be called a biosimilar. Humalog and Novolog are bio similar, functionally the same but different.
Now recall that most people in our community get very upset if the insurance company changes formulary and the company is changed. Well in the bio medication community A change might be truly devastating. in today’s world Bio-Similar companies are now making a large swath of of very expensive medications.
For instance, my RA medication has a list price of 25K per administration with 6 doses per yea.r $125K. when bio similar comes on the market it will likely cost about 80K per year. A large incentive to switch.
But since i never see the vial i might never know what i got, if I am not informed before hand. In fact i might not know what it I received ever.
For that reason those us who use these medications we are demanding that non medical forced switching not be allowed. It goes like this if a docotr prescribes differently then fine, that is a medical reason. If not then switching cannot be be done unless our doctor and we agree.
We ask for general support for our position. We know that someday Humalog and Novolog may be biosimilar insulin, but eventual insulin will be more broadly produced. After all if the biosimilar manufacturers have set up to make RA medications. they can certianily produce bio similar insulin. Please help us stop non medical switching)
