Look into "prior authorizations" with your insurance company. This will allow you to get 30 a month for the same co-pay. Your insurance company will fax a form to your doctor who will have to explain why youu need more than twelve a month (your lucky to get twelve, I only get four). If you have a CDH you doctor should have no problem doing this for you, it is common practice. Once approved, the "prior authorization" last for one year. You can update every year. This will ensure you can be proactive with taking the Frova and have a lot more pain free days. Twelve doesn't last very long when you sometimes have to take two a day.
Just call the customer service # on the back of your insurance card and ask if this is allowed for Frova. When they say yes, ask them to fax the appropriate paperwork to your doctor. Follow up with the nurse at your doctor's office to let them know what you are needing and there should be no problem. It takes a few weeks for everything to be put into place.
I am now on a different medication, but I did this for four years. I was able to get 30 Frova a month for a $10 co-pay.
I hope this is helpfull information.
