Hello doctor my father and husband are covid positive and was having fever last week, and now the fever subsided but is having couch on n off while talking, laughing and occasionally sleeping. No chest pain or difficulty breathing. Is steam inhalation good for this? What are the warning signs which we should be careful about?

Salbutamol syrup 10 ml thrice daily for 7 days is advised to the patient. The signs include difficulty reathing,fever,loss of taste,chills,cough ,headache ,bluish discolouration of lips and face etc.
