Thanks for using Health Care Magic Forum,
A 6months old baby doesnt need prilosec
(do not continue Tab.Prilosec as it is used after 1year of age for Gastro Esophageal Reflux Disease
There is no possibility of Hydocephales(water in brain) to occur because of Tab.Prilosec .
Do Not Panic.
Consult a Pediatric Surgeon as early as possible as Hydrocephalus
in advanced / in child needs surgery to drain water from brain by cerebral shunts.
Wishing a Speedy recovery to your 6Month old Son.
I Hope I Provided Useful Information. Do ask Furthur Questions to help You get well soon.
