Oral thrush in newbies

MiMi • Mommy of 5 💙💖💙💙💙 Baby Ewing Arrived 7/22/19 👣 Baby Ewing #2 Arrived 8/4/20 🤱🏽

My 3week old has Oral thrush and is currently take nystatin for it. My concern is how long does it take to actually start working or what can i do to help speed up the process?????? I wipe his mouth out after every feeding and changes his bottles/pacifiers as well. My baby seems so irritated when he tries eatting 😖.
