1. What is Tamiflu?
Tamiflu (oseltamivir) is an antiviral medication used to treat and prevent influenza (flu). It works against influenza A and B viruses.
2. What is Tamiflu used for?
Tamiflu is used to reduce the severity and duration of flu symptoms and may lower the risk of complications, especially in older adults, young children, pregnant women, and people with chronic medical conditions.
3. How does Tamiflu work?
Tamiflu blocks an enzyme the flu virus needs to spread inside the body. This helps slow the infection and allows the immune system to recover more effectively.
4. When should Tamiflu be started?
Tamiflu works best when started within 48 hours of symptom onset. It may still be beneficial in severe illness or high-risk patients even if started later.
5. How is Tamiflu taken?
Tamiflu is usually taken twice daily for 5 days for treatment, or once daily for prevention, as prescribed. It can be taken with food to reduce nausea.
6. What are the common side effects?
Common side effects include nausea, vomiting, abdominal pain, headache, and dizziness. Taking it with food often helps reduce stomach upset.
7. Are there serious side effects?
Rarely, serious side effects such as allergic reactions or sudden behavioural changes (especially in children) may occur. Seek medical attention if unusual symptoms develop.
8. Who should take Tamiflu?
Tamiflu is most beneficial for people at higher risk of flu complications, including the elderly, pregnant women, young children, and those with heart, lung, kidney, or immune conditions.
9. Can Tamiflu prevent the flu?
Yes. Tamiflu can be used after close exposure to someone with flu to reduce the chance of developing infection, particularly in high-risk individuals.
10. Is Tamiflu a substitute for the flu vaccine?
No. Tamiflu does not replace vaccination. The flu vaccine remains the best way to prevent influenza and its complications.
