Guaifenesin AC for Viral infections

Guaifenesin AC is a combination of Guaifenesin(an expectorant*) and Codeine phosphate(an anti tussive*) .This drug is used in treatment of cough and chest congestion due to viral infections like Flu or common cold and other respiratory diseases.
             This combination is used only for short term/temporary infections and not for long term breathing problems.
       Guaifenesin AC can be administered with 4 to 6 hours intervals. Don not exceed the prescribed dose . When symptoms of over dosing like irregular heart beat, loss of consciousness ,slow or shallow breathing etc are seen contact your doctor immediately

*Expectorant -It increases the amount of hydration of secretions(respiratory) , resulting in more yet clearer secretion and as a consequence lubricating the irritated respiratory tract .
*Antitussive- a cough suppressant

Cough still continues after Viral infection

Post viral Cough is a condition that follows viral respiratory tract infections like Flu or Common cold . This usually happens because the receptors that were responsible for cough stimulation during previous infection are up reugulated and continue to stimulate after the virus is eliminated.
    This condition usually goes away on its own . However  increase in cardiac activity such as jogging ,running and other related cardiac activities help .
Cough suppressant drugs containing codeine may help .
