Hi , I am Dr.Kadhir,
There are quite a number of reasons for cough,
At first i would like to know whether she is a wheezer . if so and if u have the blue inhaler (
salbutamol) give it to her. sometimes you can even hear the wheeze.
If not then it is important to know whether its due to
injury (mucous tear and irritation due to cough) or dryness of the throat (pharynx and
larynx) then you can give her some soothing agents like honey which could give dramatic relief.
if u have any cough syrup at home which contains
codeine in it ,you can give it 5 to 10 ml which may give her some relief.
All the above advice are just
first aid measures. If her cough or her consciousness gets worsening or her breathing gets distressed call for ambulance immediately.
it would be difficult to give you a specific advice without getting a focused history and examining her. Thank you for your consultation in healthcare magic.
