Is anyone taking Gralise and if so does it help peripheral neuropathy?

For those interested, a quick web search shows that Gralise is an extended release form of gabapentin (once daily taken in the evening).

Thank you, Bcool123

Has anyone had success appealing to Medicare for approval of Gralise?
Gralise is working for my 80+ year old Mom also, but the best price of $478 for 30 tablets/month (using a discount coupon) is a challenge. Was using a GoodRx coupon where we paid for $40 for 28 tablets/month, but GoodRX changed coverage in 12/2024 to reduce the total by only $40 (new best price in our area of $478 per month). Amazon Prime filled once for $260+ but then denied additional refills with Prime pricing. Came to learn Prime pricing is not available on this medication even though Gralise is not on the Medicare formulary and we aren't billing insurance. Medicare will not allow the use of Amazon's Prime rate for anyone eligible for Medicare or other Plan D options. Newer gabapentin ER is also not on the formulary. Any appeal thoughts are appreciated.

@kcproud
Is the immediate release version of gabapentin taken multiple times a day not effective like the extended release form?
If only the extended release is helpful perhaps the manufacturer has a low cost program available.

Thank you for the input. The IR version is effective for a short period of time, but the effectiveness tapers very quickly. This results in only a short period without manageable pain. The ER lasts all day.
There is a low cost program available, but it is not open to anyone who is eligible for Medicare. These plans are available to only those with commercial insurance plans. "Offer not valid for prescriptions reimbursed under Medicaid, a Medicare drug benefit plan, TRICARE or other federal or state health programs (such as medical assistance programs)." Once a person is of an age to be eligible for Medicare, the options quickly disappear. It is frightening.
