Numerous drug companies offer programs if you qualify financially. I haven't personally tried them but from my understanding they offer the medicine at reduced cost for those without insurance and/or have low incomes. Here are the some websites for their patient assistance programs by company.

Also Walgreens has a prescription drug card that is $20 a year provides discounts on some brand name drugs and has generics for as little as $1. You would have to check to see what the coverage would be for your medicine. You can check online at
