Some money saving advice for prescriptions

In the mail today, along with my free Kashi cookie (which, btw, I didn't care for - yuck), I got a letter from my insurance company. They were advising us as to how to save some money at the drug store. They suggested that when we ask the doctor for a prescripton refill, to see if he would be willing to make the dosage larger. For example, if a prescription we take is 10 milligrams, to ask if he would be willing to double it to 20 milligrams (the same amount of pills - say a one month supply), and once that prescription is filled, to simply cut the pill in half. Voila! 2 months worth of prescription for 1 month's price at the drug store. Although I was skeptical, they also sent a letter, saying this would be paid for, and was acceptable to them as an insurance company, and that we could take that with us to the doctor and pharmacy. Interesting! So, before you run off to CVS to do this, check with your insurance carrier. (As a note - the insurance campany that sent us this letter is from Anthem Blue Cross.)
