What should I do if a child keeps coughing?

If a child's persistent cough is caused by allergies, antiallergic medications such as loratadine or cetirizine can be used to relieve symptoms. If the cough results from bacterial infection, antibiotics such as cefuroxime or amoxicillin may be used to control the infection. If it is due to a viral infection, antiviral drugs such as antiviral oral liquid or ribavirin can be administered.
