There are drugs your doctor may prescribe for treating the flu that are called antivirals. These antiviral drugs are not sold over-the-counter. You need to have a prescription from your physician in order to get them. These drugs can make you better faster and may also prevent serious complications. Antiviral drugs are different from antibiotics. Antiviral drugs fight against the flu in your body where as antibiotics fight against bacterial infections. Flu symptoms can include fever, cough, sore throat, runny or stuffy nose, body aches, headache, chills and fatigue.
