Welcome to HealthcareMagic forum.
It looks like your husband is suffering from upper respiratory infection
. He is prescribed antibiotics and cough syrup.
Antibiotics take a few days - 3 days to produce significant improvement in health. Taking 3 doses instead of 2 will not help in faster recovery. So avoid over dosing
Instead try deep steam inhalation with essential oils like menthol / eucalyptus oil / karvol
plus capsule thrice a day; take paracetamol
500mg thrice a day; warm fluids; plenty of fluids, vegetable and fruits; adequate rest and multivitamin
pills. These will help in faster recovery.
Hope this helps.
I wish your husband speedy recovery.
