Mama, please take your baby to the doctor or ER right away, vomiting after taking medicine, especially with phlegm, needs to be checked immediately para sure na okay lang siya at na-absorb nang tama ang gamot.
Hindi ko mabibigyan ng sagot kung uulitin mo or hindi dahil medical ito, pero the doctor will tell you exactly what to do next, baka kailangan i-adjust ang dosage, or switch ng medicine, or may ibang nangyayari. Dali na, mama!
