influenssalääkkeitä

Influenssalääkkeitä are medications used to treat or prevent influenza, commonly known as the flu. These antiviral drugs are distinct from antibiotics, which are used to treat bacterial infections. Influenssalääkkeitä work by interfering with the influenza virus's ability to replicate within the body.

There are two main classes of influenssalääkkeitä available. The neuraminidase inhibitors, such as oseltamivir (Tamiflu), zanamivir (Relenza), and peramivir (Rapivab), are the most commonly prescribed. These medications work by blocking an enzyme that the virus needs to release from infected cells. The other class, the adamantanes (amantadine and rimantadine), were historically used but are now largely ineffective against circulating influenza strains due to widespread resistance.

Influenssalääkkeitä are most effective when started within 48 hours of the onset of flu symptoms. They can help reduce the severity and duration of illness, as well as decrease the risk of serious complications like pneumonia, bronchitis, and sinus infections. While they do not cure influenza, they can be a valuable tool in managing the infection.

In addition to treatment, some influenssalääkkeitä can also be used for prophylaxis, meaning they are taken to prevent infection in individuals who have been exposed to the virus. This is often considered for individuals at high risk of complications from influenza. The decision to use influenssalääkkeitä, either for treatment or prevention, should be made in consultation with a healthcare professional. It is important to note that vaccination remains the primary and most effective way to prevent influenza.
