Respected user, hi I evaluated your query thoroughly .
* Severe cough with red blood in sputum is indicative of definite underlying
   pathology which may be ranging from severe acute 
bronchitis ,    
pneumonia, 
pleural effusion ,consolidation ,  
pulmonary tuberculosis or 
   other tumors of  the lungs , other conditions .
* So I don`t recommend any of the empiric treatment just for the sake of 
   feeling good , I request you to immediately consult with 
CT scan report 
   along with any laboratory work up , x-ray report if available for precise 
   study of the case & plan management guidelines accordingly for better 
   recovery .
Hope this helps you .
