We do not use Pepto-bismol
) in children.
Since only one dose was given, don`t worry.
Do visit your Pediatrician
to know the cause for her tummy ache.
Till then for vomiting you may give her Domperidone
syrup in a dose of about 0.3mg /kg /dose. You may repeat it 3 times a day.
Your doctor will assess the site and nature of pain and advise accordingly.
If its just a gastritis- medications like lanzoprazole will do.
hope my answer helps you.
Wish a speedy recovery for your kid.
