Ms. lybrate-user it's unfortunate to hear such issue. All medicines have some or other side effects and your child is suffering from ototoxicity of typhoid
medications. Keep in mind to inform any doctor you consult for your baby in future to inform about this event to prevent further damage. Secondly you didn't mention how bad the hearing loss
is. Send audiometry and bera reports so that I can advise accordingly. If the damage is permanent then hearing aid
will be the only option. There are some newer treatment options like intratympanic dexamethasone etc which can help ear recover from the damage. Pls meet any senior Ent consultant at your town. Get well soon.
