Thank you for your query.
It appears that your friend is developing a viral infection. You need to give him acetaminophen
1 tab. 4-6 hourly if the temperature is above 100F. In case cough
is persisting you can start with a decongestant medication. If there is not improvement in the next 24-48 hours or some other problem arises then a visit to the doctor is warranted.
I hope I have answered your query to your satisfaction.
Wishing your friend an early recovery.
