A friend of mine who works in a clinic in MD was telling me about how patients at the clinic are having a more difficult time getting testosterone cypionate 10 ml vials (200 mg/ml) dispensed at community pharmacies, after they've been getting testosterone 10 ml vial prescriptions filled for years without any issues.
Typically, the sig for these prescriptions is inject 200 mg (1 ml) IM every other week or 100 mg (0.5 ml) every week, with a quantity of 10 ml. A 10 ml vial will usually last someone between 4.5 to 5 months.
My friend is saying that the patients are only able to get the 1 ml vials instead of the 10 ml vial, and was asking me what I think is going on. This is concerning to the patients because the multiple 1 ml vials end up being more expensive than one 10 ml vial, as well as those that inject 0.5 ml every week tend to not be able to get full two doses, since there is some medication wasted with each injection and the vials aren't significantly overfilled.
The first obvious reason someone would have an issue getting this filled is insurance day supply limits. But from what my friend is telling me it's not an insurance issue, the pharmacist is just outright refusing to fill with the 10 ml vial, and instead will only dispense 1 ml vials, even if the patient is paying out of pocket.
I am guessing the reason for switching the 10 ml vial to 1 ml vials is because of USP standards that state that a multidose vial's beyond use date is 28 days from the first needle puncture, unless otherwise specified by the manufacturer. Therefore, even though it wouldn't be a violation of the law per se to dispense the 10 ml vial, a reasonable and prudent pharmacist wouldn't dispense a 10 ml vial with instructions to use that vial for beyond 28 days, right?
The thing I don't get and was hoping SDN could help me figure out, is that many of these patients have been getting 10 ml vials for years, and all of a sudden (over the past few months), they are having trouble getting the 10 ml vials. The USP 28-day rule isn't a new thing. Why the sudden change? Anyone know what might be driving this? Is there something else besides sterility concerns that is driving this switch from the 10 ml vial to the 1 ml vial?
