When can I consider taking antiviral medications for the flu?

Question

Hello doctor,

I am a 28-year-old woman experiencing flu-like symptoms, including a high fever, chills, a sore throat, body aches, and a dry cough. This started two days ago, and I am not improving much despite resting and drinking fluids. I am worried because I live with my elderly parents and do not want them to catch it.

Should I be tested to confirm influenza and consider antivirals like Oseltamivir?
How long does recovery usually take, and what precautions should I follow at home to avoid infecting my family members?

Please suggest.

Thank you.

Hello,

Welcome to icliniq.com.

I have read your query and can understand your concern.

A flu test (rapid influenza test or PCR (polymerase chain reaction)) can confirm the diagnosis, though during peak flu season. It may be started clinically without waiting for results. Antiviral medications such as Oseltamivir (Tamiflu) are most effective when started within the first 48 hours of symptom onset. They can shorten illness duration and reduce complications, especially in higher-risk individuals such as the elderly, people with chronic conditions, or those living with them.

Given that you live with elderly parents, it would be advisable to discuss antiviral treatment with a doctor promptly. Healthy adults recover in five to seven days, though fatigue and cough may last longer. Medical review is urgent if symptoms worsen (shortness of breath, chest pain, persistent high fever, confusion).

The precautions to protect family members include isolating yourself in a separate room if possible.

Wearing a mask when around others.
Asking them to do the same.
Washing hands frequently with soap and water or using sanitizer.
Avoid sharing utensils, towels, or bedding.
Ventilate your living space well.
If your parents have not already, they should consider getting a flu vaccination , as it reduces the risk and severity of the disease.

I hope this answers your query.
