Mama, this is really important, please call your baby's doctor or go to your pediatrician right away before giving any medicine, lalo na with G6PD. G6PD babies need special care when it comes to medications kasi certain things can trigger problems, at only your doctor can say what's safe for your little one.
I know colic is so stressful, pero this isn't something to guess on, your pedia will know your baby best and can recommend what's okay. Hugs, mama!
