Re: treatment of colds
Has he tried zicam or cold-eeze? I swear by cold-eeze if you take it at the onset of a cold. I just keep sucking on them all day. A friend just used the zicam and said she believed it did shorten the duration as well.
As far as for cough and sinus issues, I really have no suggestions as I generally hit the OTC meds pretty hard. He has reactions to all OTC cold meds or specific ingredients? I know if I take anything with dextromethorphan I'm a zombie for days, so check labels.
