When my son was an infant he had horrible ear infections. His pediatrician prescribed antibiotics but I hated having to watch him flay his little head and endure the pain until I could get him in to see his pediatrician and have him diagnosis the same condition over and over while my son waited for relief. Finally his pediatrician prescribed a medication to be used daily to prevent this condition. I believe it was called guaifenesin. Would this be correct? If not what could it have been?
