Peramivir Injection 帕拉米韦注射液

Peramivir is an intravenous antiviral drug mainly used to treat influenza A and B. Its mechanism of action is to inhibit the neuraminidase activity of influenza virus and block viral replication. As a prescription drug, it must be used strictly according to the doctor’s instructions, especially for patients who cannot take oral medications or are in serious condition.
Indications and usage scenarios
Applicable population: patients with confirmed or suspected influenza and symptoms no longer than 48 hours; those who are intolerant to oral medications such as oseltamivir or have poor efficacy.
Virus type: effective for influenza A (such as H1N1, H3N2) and influenza B.
Usage restrictions and precautions
Contraindications: Patients who are allergic to peramivir or drug ingredients are prohibited; patients with severe renal insufficiency need to adjust the dose.
Adverse reactions: May cause diarrhea, headache, injection site reactions; rare severe allergic reactions (such as dyspnea, rash).
Medication instructions and safety
Dosage and course of treatment: Adults usually receive a single intravenous injection of 300 mg, and patients with severe infection can extend the course of treatment to 5 days. The dosage for children needs to be adjusted according to weight.
Doctor’s instructions: The doctor must prescribe the medicine after evaluating the condition. Do not take the medicine on your own. During the medication, you need to monitor your kidney function and adverse reactions.
Prevention and alternatives
Irreplaceable vaccines: Flu vaccines are still the most effective way to prevent infection, and drugs are only used for treatment.
Early intervention: The best effect of medication is within 48 hours of the onset of symptoms. Delayed use may reduce the efficacy.
Note: If allergic symptoms such as chest tightness and rash occur after taking the medicine, stop taking the medicine immediately and seek medical attention. Patients with high incidence of influenza or severe symptoms should seek medical attention as soon as possible to avoid delaying treatment.
