Antiviral medications, including pills, inhalants, liquids and intravenous solutions, are taken to treat influenza, commonly referred to as the flu. Over-the-counter and prescription drugs are also recommended to provide relief from flu-related symptoms, states Flu.gov
Antiviral drugs require a prescription from a physician. In the United States, antiviral medications approved by the Food and Drug Administration include brand name drugs Tamiflu, Relenza and Rapivab, notes the U.S. Centers for Disease Control and Prevention.
Fever and muscle aches, which usually manifest after contracting the flu virus, can be treated with ibuprofen, acetaminophen and non-steroidal anti-inflammatory drugs. Cough drops and medicated lozenges can soothe a sore throat and alleviate coughing, while decongestants can provide relief for blocked nasal passages, stuffy ears and chest pains.
