for Americans only- are you able to pick up a new Lantus prescription before the old one is out?

I was told by the pharmacist that Lantus expires 28 days after opened, so I will need to pick up a new vial soon. However, I thought it was a monthly prescription? The coupons for Lantus seem to only be able to used every 30 days. So is the 28 day thing real or just a suggestion?

I am also wondering, what if you are going out of town during the time to renew? Will they let you renew early?
 
Most US people use the Lantus pens instead of the vials. A box contains five 3ml pens. Each pen is good to the last drop. The entire box can last up to a year or more depending on the cat's dose.

You use the pen just like a vial: insert insulin syringe needle into the rubber stopper and draw out the insulin.

The prescription has to specify the pens.

The 28 day thing applies to Human diabetics who can use up a vial in that amount of time. Cats and their usually teeny doses can't use up a vial in 28 days. Some people have gotten a few months use out of a vial for their cat. I've never been able to get a vial to last more than a month.

With prescriptions in general, you can renew a prescription ahead of time. Just let the vet know.

my concern was more that the insulin wouldn't be effective anymore after 28 days. but you are saying that hasn't been your experience?
