Oseltamivir is not an antipyretic, but it can indirectly relieve fever caused by some viral infections. Oseltamivir belongs to a specific inhibitor acting on neuraminidase, which is mainly used to inhibit the neuraminidase activity of influenza A and B viruses and reduce the spread of influenza A or B viruses. And antipyretics are anti-inflammatory drugs with antipyretic and analgesic effects, such as aspirin, ibuprofen, etc. Therefore, oseltamivir is not an antipyretic. However, Oseltamivir can indirectly relieve fever caused by influenza A or B viruses to a certain extent, which can be manifested as headache, muscle pain, malaise, etc. It can be used in combination with antipyretic drugs. If you are allergic to the ingredients of this product, it is prohibited to use the drug, and some patients may experience nausea, vomiting, arrhythmia and other adverse reactions after using the drug. In conclusion, fever patients need to follow the doctor’s instructions to use antipyretic drugs, do not self-medication, so as not to delay the condition.
