Oseltamivir Capsules

OSELTAMIVIR (os el TAM i vir) prevents and treats infections caused by the flu virus (influenza). It works by slowing the spread of the flu virus in your body and reducing how long your symptoms last. It will not treat colds or infections caused by bacteria or other viruses. It will not replace the annual flu vaccine.

Take this medication by mouth with water. Take it as directed on the prescription label at the same time every day. You can take it with or without food. If it upsets your stomach, take it with food. Take all of this medication unless your care team tells you to stop it early. Keep taking it even if you think you are better.

When taking whole capsules: Do not cut, crush, or chew this medication. Swallow the capsules whole.

When mixing capsule contents with liquid: Open the capsule and mix the contents in a small bowl with a small amount of a sweetened liquid such as chocolate syrup, corn syrup, caramel topping, or light brown sugar (dissolved in water). Stir the mixture and take the dose right away after mixing.

If you have the flu, you may be at an increased risk of developing seizures, confusion, or abnormal behavior. This occurs early in the illness, and more frequently in children and teens. These events are not common, but may result in accidental injury to the patient. Families and caregivers of patients should watch for signs of unusual behavior and contact a care team right away if the patient shows signs of unusual behavior.

To treat the flu, start taking this medication within 2 days of getting flu symptoms.

This medication is not a substitute for the flu shot. Talk to your care team each year about an annual flu shot.
