HI, thanks for using healthcare magic
Symtoms of sinus disease can occur most commonly as a result of allergies, viral or bacterial infection.
In the case of a bacterial infection, like your husband is experiencing, antibiotics are needed as part of the therapy. Normally when amoxicillin
is used for sinus infection
, it is taken 3 times a day. IF he is using twice daily , it would not be as effective.
In severe cases or where is a slow response the antibiotics have to be taken for an extended period of time (up to 3 or 4 weeks).
He may want to consider speaking to the doctor regarding the dosing
interval of the amoxicillin or changing to another antibiotic that may help him.
In terms of the flu
, it can cause severe symptoms. The main aspect of treatment in most persons is rest,fluids and the use of medication to treat any symptoms (as he is already doing)
I hope this helps
