Disease description:

Diagnosed with influenza A, I know that oseltamivir can be taken. But I heard there are other medications as well. I'd like to ask, besides oseltamivir, what other drugs are available for treating influenza A?

Aside from oseltamivir, medications for treating influenza A also include zanamivir, peramivir, acyclovir, ribavirin, and baloxavir marboxil. It is important to use these medications under the guidance of a physician.

Zanamivir belongs to the same class of drugs as oseltamivir—neuraminidase inhibitors. It is administered via inhalation and is suitable for children over one year old and adults. Peramivir, another neuraminidase inhibitor, is given intravenously and is primarily used for severe cases or for influenza A patients unable to take oral medications.

Acyclovir is an antiviral drug mainly used to treat infections caused by herpes viruses. In the treatment of influenza A (H1N1), acyclovir may also be used to inhibit viral replication.

Ribavirin is a broad-spectrum antiviral medication that can be administered orally, intravenously, or via nebulization. It is commonly used to inhibit viral replication in the treatment of influenza A (H1N1) and other viral respiratory tract infections.

Baloxavir marboxil is a prodrug that is converted into its active form after oral administration. It inhibits viral replication at its source and is effective against both influenza A and B viruses. It is indicated for individuals aged 12 years and older; however, it is contraindicated for pregnant women, nursing mothers, and those with allergies. Its advantage lies in achieving effective therapeutic results with a single dose.
