Dont worry , you are on right treatment
Thanks for writing to healthcare magic.
Pus coming out of ear is common in kids.
It is mainly because of respiratory infection which extends from the throat to middle ear and resulting in hole formation.
Do not worry.
You can give mucolite
and t minic together.
You need to give all the medicines together for your baby's treatment to get over.
Do not worry about side effects usually they are mild like vomiting
and loose stools which will settle as soon as the course is over.
The hole will close by itself once the course is over
You have to give the medicines . If treated well,pus will stop coming out.
One more point : Keep ear dry, do not use buds, just clean the outer part with soft cloth end.
Wishing your kid speedy recovery.
