Regardless of the type of medication you are taking, you can google it for manufacturer coupons. Last year there was a $30 discount coupon
online for Lyrica. This discount was on top of your copay, so that if your co was $25. the medication was free. The coupon lasted a year.
Also, there are offerings for Rx discount cards. Some of these are only available if one isn't on a Federal or State funded ins. program, others can be used in addition to insurance.
