Thanks for posting your query.
It seems like your father has an acute viral fever
. Please give him steam inhalation twice daily, he can also take Dolo
650mg three times a day, after food for next 2 days. Anti-allergics like Cetrizine
will help in releiving the cold
He should also take adequate rest. He may take a day off at work and rest at home. Let him continue to take Aciloc.
I wish him quick recovery.
