Lantus throw away?

That just switch Felix from prozinc to Lantus. The Lantus says to discard after 28 days. Is that really the case?
 
Most folks will use a pen until the last drop. A lot depends on the size of the dose if you're using a vial. Generally, unless you see "floaties" your Lantus is good.
 
What a cutie. My vials lasted about 5-6 months when potency was lost and I threw them out. I switched to pens that were used to the last drop.
