It may be worth a shot…I take Beta Alanine for itch…I have Aquagenic Pruritus and neuropathy itch, Both stop when I take BA…it is an otc supplement that is typically used as a preworkout supplement. On the Aquagenic Pruritus fb group, someone discovered that when they took their preworkout supplement, they didn’t itch and isolated it to Beta Alanine. I’ve been taking for 6 + years….I buy the NOW BRAND on Amazon and take 750 mg every 4 hours as needed…cost is under $20.
