Throat infection (bacterial or viral) and cough may be due to seasonal changes or contact with allergen and dust particles.

Safe antibiotics like Cephalexin, Combined Amoxicillin & Cloxacillin etc along with Anti-histamine drug like Levocetirizine and cough syrup with terbutaline and ambroxol can be given to treat throat infection. Kindly, procure a complete prescription from your DOCTOR.

In addition, you must maintain oral hygiene to avoid repeated infection. You can use HEXIDINE mouth wash regularly in addition to above and brush your teeth 3 to 4 times daily or after taking foods each time.

Some basic home remedies can improve your condition and prevent recurrence:
