The flu, or influenza, is a viral infection causing fever, cough, sore throat, muscle aches, and fatigue. It spreads through respiratory droplets produced when an infected person coughs or sneezes.
Most people recover within a week to ten days with rest and supportive care. This includes plenty of fluids, over-the-counter pain relievers like ibuprofen or acetaminophen for fever and aches, and avoiding strenuous activity. Good hydration is key for recovery.
Antiviral medications, such as oseltamivir (Tamiflu) and zanamivir (Relenza), can shorten the duration and severity of the flu, but they are most effective when started within 48 hours of symptom onset. Your doctor can determine if antiviral treatment is appropriate for you based on your individual health status and risk factors.
Doxycycline is an antibiotic, effective against bacteria, not viruses. Therefore, it’s not used to treat the flu. Antibiotics are ineffective against viral infections. Using antibiotics inappropriately contributes to antibiotic resistance.
Preventing the flu is best achieved through vaccination. The annual flu vaccine is recommended for most people over six months old. Practicing good hygiene, such as frequent handwashing, also helps minimize transmission.
If you experience severe flu symptoms, such as difficulty breathing, chest pain, or persistent vomiting, seek immediate medical attention. Early diagnosis and treatment are important for preventing serious complications.
