Oseltamivir - Overview

Oseltamivir is the generic name for Tamiflu - a prescription antiviral medication for influenza A and B. People who might need an oseltamivir prescription can use Push Health to consult a medical provider who can prescribe the medication to a local pharmacy when appropriate to do so.

What Is Oseltamivir Used For?

Oseltamivir, marketed under the name Tamiflu, is a medication sometimes used in the treatment of uncomplicated influenza in some adult patients. The medication is both used for treatment of uncomplicated influenza and for prevention in selected people after close exposure.

Oseltamivir belongs to a class of medications known as neuraminidase inhibitors and is thought to work by limiting the influenza virus's ability to release new particles from infected cells. Oseltamivir may also reduce the risk of developing symptoms of influenza when used preventatively. Oseltamivir is an alternative to the medication Xofluza. It does not treat COVID-19, the common cold, or bacterial infections such as strep throat or pneumonia.

Oseltamivir - Dosage and Cost

Oseltamivir is commonly prescribed for both influenza treatment and prevention (customized the the individual needs of the patient):

  • Treatment: For acute uncomplicated influenza, start as soon as possible (ideally within 48 hours of symptoms).
  • Prevention: For selected people after close exposure when appropriate.

A common adult treatment course is 75 mg twice daily for 5 days. Prevention is often prescribed as 75 mg once daily for 10 days after exposure. Kidney disease may require modified dosing. Children are dosed by weight. Oseltamivir is generally available as 30 mg, 45 mg and 75 mg capsules. An oral suspension is also available if capsules cannot be swallowed. It is recommended that the medication be taken with food if nausea occurs. If a dose of medication is missed, take it when remembered unless it is close to the next dose. It is not recommended to double up.

Generic oseltamivir is relatively affordable, costing approximately $35 for ten oseltamivir 75 mg capsules at many pharmacies. Some insurance plans may cover the cost and prescription discount cards may be available. Branded Tamiflu costs more.
