It depends on what type of pneumonia you have. Is the pneumonia viral or bacterial? Further, if the pneumonia is bacterial, do you know the causative microorganism? My best advice to you is to consult your physician or health care provider! Only your health care provider can truly answer this question because you may need a chest x-ray, you may need a sputum culture and sensitivity test and you may need further diagnostic test's to properly diagnose your condition. The area of the country in which you live can also play a part in your scenario because certain etiologic agents are endemic in certain geographic locations. Remember, we must first identify your specific type of pneumonia. Go see your doctor.
I would highly suggest you consult a board licensed physician, a registered nurse or a pharmacologist.
