Taking oseltamivir for a high flu fever does not immediately reduce the fever, and fever-reducing medications are mainly non-steroidal anti-inflammatory drugs such as ibuprofen and acetaminophen.
Oseltamivir is an antiviral drug, which is a neuraminidase inhibitor, and can specifically inhibit the neuraminidase enzyme of influenza A and B viruses, thus inhibiting the release of the virus and reducing the spread of the virus. When the influenza virus is controlled, the patient’s fever will improve, but it takes a process to inhibit the influenza virus and cannot lower the body temperature within a few hours.
Patients with high flu fever can take physical cooling, such as alcohol baths and warm water baths, or take oral non-steroidal anti-inflammatory drugs, such as ibuprofen and acetaminophen, as prescribed by the doctor, which can help lower the temperature of patients with influenza more quickly.
Taking oseltamivir may cause nausea, vomiting, headache, dermatitis and other adverse reactions, and is contraindicated in patients with allergies.
Patients with influenza accompanied by fever should go to the hospital in time and take the medication according to the doctor’s instructions, avoiding self-medication to avoid serious adverse consequences.
