Confused About Prescription Refill
I am very confused about my dosing.
My current prescription is BPI Tirzepatide + B6. The concentration of the Tirzepatide only in the 3ml vial is 60 mg/3 ml = 20 mg/ml. My dose is 68 units (AKA 68 ml) per week. This dose would then calculate to 13.6 mg per week. Right?
I now need a refill. I told the caregiver that I had titrated up to 75 units (AKA 75 ml) and am finally getting appetite suppression and slow weight loss. It is working beautifully! I asked that the 75 units be approved with an alteration in the prescription. As we know, BPI has been shuttered. This is the complete wording on the refill that I have been given:
"Casa Tirzepatide/B6 13.5mg (3 month)
Inject 45 units subcutaneously once weekly
This is currently the highest dose available for this formulation."
It seems to me that I will be receiving a slightly less concentrated amount and have been instructed to inject less.
What am I missing?
