Influenza, more commonly known as the flu, is caused by a virus that affects the respiratory system. The flu generally isn't a serious illness unless you have a pre-existing disease that compromises your immune system---then rarely it may require hospitalization and prove to be fatal. High-risk groups are encouraged to get an annual flu shot, but this does not guarantee complete protection. Common medicines used to treat flu symptoms include over-the-counter pain relievers and prescription antivirals.
Pain Relievers
Other than drinking plenty of liquids and getting plenty of rest, the Mayo Clinic suggests over-the-counter pain relievers to make you more comfortable while dealing with the flu. These pain relievers include acetaminophen and ibuprofen. Caution should still be exercised, however, when taking these medications, as ibuprofen can cause stomach pain and bleeding, and acetaminophen can stress the liver if too much is taken.
Tamiflu
Some doctors may prescribe the antiviral medication Tamiflu, or oseltamivir generically, for influenza and H1N1 influenza. This medication keeps the virus from reproducing, shortening the length of your bout with the illness. The prescribed dose must be started within two days of experiencing the first flu symptoms, and it can be used to prevent the illness as well. This antiviral may only be used on patients older than 1-year of age, and should not be used near the time of receiving a live attenuated influenza vaccine. Tamiflu also interacts with many medications, and should not be used by pregnant or breast-feeding women. Your doctor or pharmacist should also be aware of any existing health problems or food allergies prior to taking Tamiflu.
Relenza
Also a prescription antiviral medication, Relenza is the brand name of the drug zanamivir. It is used in patients at least 7-years-old, but may help prevent the flu in patients as young as 5. This medication must also be started within two days of experiencing flu symptoms. It works by interfering with the virus' ability to grow and spread in the respiratory system, according to Drugs.com. It should not be taken by individuals with a milk protein allergy; this is also true for those who are pregnant or breast feeding, anyone taking medications of any kind, and for people who have other allergies or medical conditions. Consult a doctor if about these exceptions. As with Tamiflu, Relenza should not be taken near the time of receiving a live attenuated influenza vaccine.
