Just a couple of weeks back, I was having fever so I started taking this medicine called Paracetamol 650. It is meant to get rid of fever but even thought I was taking it, the fever was returning after a couple of hours. That medicine was not working for me at all. I went to the doctor and got to know that I was suffering from Dengue (initial stage). He gave me some strong antibiotics and other medicines for the different symptoms I was having which finally helped me recover from it.
