Is Oseltamivir effective for the flu, and what are its side effects?
Patient's Query
Hello doctor,
I am feeling terrible with the flu right now! A friend mentioned an antiviral drug called Oseltamivir, and I wonder if it is worth trying. I have heard that flu viruses can mutate and develop resistance to medications. Is that true? If so, could this mean the drug might not work for me? Also, I am concerned about potential side effects—are they common with Oseltamivir? I am already feeling pretty miserable. Additionally, I am a bit confused about how antivirals work. Do they kill the virus or just prevent it from spreading? How effective are they? I want to start feeling better as soon as possible. Any insights would be appreciated.
Thank you.
Hi,
Welcome to icliniq.com.
I read your query and can understand your concern.
Oseltamivir (Tamiflu) is an antiviral used to treat and prevent influenza. It works by blocking neuraminidase, an enzyme the virus needs to spread, thereby reducing the severity and duration of symptoms.
For best results, it should be taken within 48 hours of symptom onset. It can shorten the duration of symptoms by one to two days and reduce the risk of complications. Although flu viruses can mutate and develop resistance, this is rare.
Common side effects include nausea, vomiting, and headache, with less common ones being diarrhea, abdominal pain, insomnia, and dizziness. Given the severity of your symptoms and timing, starting Oseltamivir early could be helpful.
I hope this helps.
Please revert to assist you further.
Thank you.
