What can you do once you have a viral fever? If you are suffering from viral fever it is best that you take enough rest and have warm soothing food like soup and khichidi till you get better. If you have very severe symptoms like high fever, extreme body ache, etc. you should visit your doctor for some medicines to give you some symptomatic relief. A number of people tend to self-medicate during such times, relying on antipyretics, analgesics, and antibiotics to help them out, but remember that self-medication is a bad idea. More importantly, a viral fever will not heal with antibiotics. Antibiotics are medicines that are made to kill bacteria, they cannot kill viruses; so don’t take antibiotics for viral infections.
