Hi, Welcome to HealthcareMagic Forum.
No Medicine come without side effects, but don't worry about them as they may or may not occur. The common side effects of these medicines cold be constipation
, Skin rash
, but it is not necessary that they should occur.
Just give them to your baby as directed by your Doctor and take your baby for regular follow up.
Do not stop breastfeeding
I Wish him Good Health.
