Flu medicine refers to medications used to alleviate symptoms of the influenza virus, commonly known as the flu. These medicines can help reduce fever, relieve body aches, and ease coughs. Over-the-counter options include acetaminophen and ibuprofen, which are effective for pain and fever relief. In some cases, doctors may prescribe antiviral medications like oseltamivir (Tamiflu) to shorten the duration of the flu if taken early. It's important to stay hydrated and rest while recovering, as these practices support the immune system in fighting off the virus.
