Tamiflu is an antiviral medication that works by preventing the flu virus from spreading inside the body. It is usually taken orally twice a day for 5 days, but can also be used to prevent flu infection if taken within 48 hours of exposure.
Relenza is another antiviral medication that is inhaled using a special device. It also works by preventing the flu virus from reproducing and spreading. It is usually taken twice a day for 5 days.

It is also important to practice good hygiene, such as washing hands frequently and covering coughs and sneezes, to prevent the spread of the flu.

The best time to take flu medicine for maximum effectiveness depends on the type of medication you are taking. For antiviral drugs like Tamiflu, it is recommended to start treatment within the first 48 hours of experiencing flu symptoms. This is because these drugs work by stopping the virus from multiplying in your body, and the earlier you start taking them, the more effective they are likely to be.
For over-the-counter medications like ibuprofen or acetaminophen, it is best to take them as soon as you start experiencing symptoms like fever, body aches, or coughing. These medications work by reducing inflammation and relieving pain, so taking them early on can help manage your symptoms and make you more comfortable.
It is important to follow the instructions on the medication label and talk to your doctor or pharmacist if you have any questions or concerns about the timing or dosage of your flu medication. Additionally, it is always a good idea to get plenty of rest, drink fluids, and practice good hygiene to help your body fight off the flu virus.
