Also some insurance companies have mail order which you might investigate. Some times you can get 3 months medications for the price of 2 months co-payments. On my mother-in-laws insurance her generics are free on mail order. Also go on the websites of the manufactures, sometimes they have coupons for a % off your bill. When I joint the avandia program I got a couple months free avandia, plus they send coupons at times. Also ask your md for samples. I use to work at a doctors office and we got enough samples to open a pharmacy. Another thing, if your job offers a flexible spending account, I find that is nice as well. it reduces your taxes and you can contribute up to 3000 a year to them. good luck.
I am would suggest that you see if you can qualify for Medicaid, or if your county or state have programs to help. I know that NY has several county run programs that help pay for diabetic supplies. I would suggest contacting your department of social services, and see what you might qualify for.
You might also contact the manufacturer of the medications and explain the situation; some pharmaceutical companies have assistance programs for those who cannot afford their medications.
I hope this helps. Good luck
