How would flu medications work if you got the flu?

Antiviral medications are used to treat influenza (the flu). They work by interfering with the virus's ability to multiply and spread. There are two types of antiviral medications: neuraminidase inhibitors (NAIs) and adamantanes.

Neuraminidase inhibitors (NAIs) are the most commonly used antiviral medications for the flu. They work by blocking the action of neuraminidase, an enzyme that the flu virus uses to release new virus particles from infected cells. NAIs can reduce the severity of flu symptoms and shorten the duration of the illness. They are most effective when started within 48 hours of the onset of symptoms.

Adamantanes are less commonly used antiviral medications for the flu. They work by blocking the action of the M2 protein, which is essential for the flu virus to enter cells. Adamantanes can be effective in preventing and treating the flu, but they are not as effective as NAIs. They are also more likely to cause side effects, such as dizziness and confusion.

Antiviral medications can be an important part of treating the flu, especially for people who are at high risk of developing complications, such as older adults, people with chronic medical conditions, and pregnant women. However, antiviral medications should not be used as a substitute for getting vaccinated against the flu. Vaccination is the best way to prevent the flu.

How to take flu medications

Antiviral medications are usually taken by mouth. The specific dosage and duration of treatment will depend on the type of medication and the severity of your symptoms. Be sure to follow the instructions on your prescription label carefully.

Side effects of flu medications

Antiviral medications can cause side effects, such as nausea, vomiting, and diarrhea. These side effects are usually mild and go away after a few days. However, some people may experience more serious side effects, such as dizziness, confusion, and hallucinations. If you experience any severe side effects, stop taking the medication and contact your doctor immediately.

Precautions

Antiviral medications are not recommended for people who are allergic to the medication or who have certain medical conditions, such as liver disease or kidney disease. Be sure to tell your doctor about all of your medical conditions before you start taking an antiviral medication.

Important notes

Antiviral medications can be effective in treating the flu, but they are not a substitute for getting vaccinated. Vaccination is the best way to prevent the flu.

If you start experiencing flu symptoms, see your doctor as soon as possible to get tested for the flu and to discuss treatment options.
