Few suggestions when dealing with cost of medications,
1. Check with provider if OK to take the generic version. Zolpidem or zolpidem tartrate is the generic name of Ambien.
2. Check the discount coupon sites, such as GoodRx. I do not take Ambien, but I have other medications my insurance plan does not cover and able to get a discount using GoodRx coupon at my pharmacy.

If neither of those options work, talk to your provider about alternative options to help with sleep.
