Medications. Typically, the use of medications are not necessary to cure an occurrence of the flu. That said, certain drugs might ease the symptoms, shorten the duration or prevent potentially serious complications from developing. Commonly prescribed medications include anti-viral preparations designed to lessen illness duration. Medications might also be prescribed or taken in accordance with the specific manifestations a patient is experiencing. Anti-diarrheal or anti-nausea drugs might provide relief to individuals stricken with bothersome digestive symptoms. Those coping with body aches may ease associated discomfort through the use of over-the-counter pain relieving drugs.
