Optum Perks, Optum’s free discount coupon, lists these prices for Phexx without insurance. Show the coupon from its page at the pharmacy; it can’t be used with insurance.

There isn’t one. An authorized generic is Phexx itself, from the same company, sold without the brand name, and usually for less. For now Phexx is the only choice; its maker’s savings card can lower what you pay.
No generic is sold yet. Generics usually come once the brand’s patents and exclusivity end. Until then, the maker’s savings card is the way to pay less.
