Dear friend, welcome and thanks for entrusting your query here at Healthcaremagic!
I am Dr. Prasad Akole (Critical Care Expert- http://bit.ly/Dr-Prasad-Akole) and am glad to address to your query here.
The change in speech and mentation (? Drowsiness
) is more of a symptom of severe dehydration
and infective diarrhea than a medicine side-effect.
The medications given to her are not likely to cause such side-effect.
If the neurologist
felt it not to be serious, he meant no structural brain problem.
But altered mentation is a sign of dehydration or electrolyte imbalance
, commonly low sodium (hyponatremia
). That is why she was given ringer lactate iv. Need to check sodium and degree of dehydration frequently and replace lost volumes i.v. as well as much as possible by mouth.
Phenargan may make the patient more drowsy and hence may add to the confusion. It is better to hydrate and treat any infection.
I hope to have answered your query satisfactorily. I would be glad to answer any further queries. Please ask for any clarifications before closing and rating this answer.
Take care and please keep me informed of your progress at http://bit.ly/Dr-Prasad-Akole
Good Luck! Thank you!!
