OSELTAMIVIR – ORAL (oss-el-TAM-eh-veer)
COMMON BRAND NAME(S): Tamiflu
USES OF TAMIFLU: Oseltamivir is used to treat symptoms caused by the flu virus (influenza). It helps make the symptoms (such as stuffy nose, cough, sore throat, fever/chills, aches, tiredness) less severe and shortens the recovery time by 1-2 days. This medication is also used to prevent the flu if you have been exposed to someone who already has the flu (such as a sick household member) or if there is a flu outbreak in the community.
Tamiflu works by stopping the flu virus from growing. It is not a substitute for the flu vaccine. (See also Notes section.)
WHAT TAMIFLU TREATS:
- Stuffy Nose
- Sore Throat
HOW TO USE TAMIFLU: Read the Patient Information Leaflet if available from your pharmacist before you start taking this medicine. If you have any questions, consult your doctor or pharmacist.
Take Tamiflu by mouth with or without food. You may take it with food or milk to minimize stomach upset. Take this medication as soon as flu symptoms appear or as soon as possible after you have been exposed to the flu. Oseltamivir works best if you start taking it within 2 days of either of these events.
If you have the flu, take oseltamivir as directed by your doctor, usually twice a day for 5 days.
To prevent the flu, take oseltamivir as directed by your doctor, usually once a day for at least 10 days. Follow your doctor’s instructions for how long to take this medicine.
The dosage is based on your medical condition, kidney function, and response to treatment. In children the dosage is also based on weight.
Tamiflu works best when the amount of medicine in your body is kept at a constant level. Therefore, take this drug at evenly spaced intervals at the same time(s) every day. Continue to take it for the full time prescribed. Stopping the medication too early may allow the virus to continue to grow, which may result in a relapse of the infection or failure to protect you from the flu.
Tell your doctor if your condition persists or worsens or if new symptoms appear.
SIDE EFFECTS OF TAMIFLU: Nausea and vomiting may occur. If either of these effects persist or worsen, notify your doctor or pharmacist promptly.
Remember that your doctor has prescribed this medication because he or she has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects.
The flu itself or oseltamivir may rarely cause serious mental/mood changes. This may be more likely in children. Tell your doctor right away of any signs of unusual behavior, including: confusion, agitation, self-injury.
A very serious allergic reaction to this drug is rare. However, get medical help right away if you notice any symptoms of a serious allergic reaction, including: rash, itching/swelling (especially of the face/tongue/throat), severe dizziness, trouble breathing.
MISSED DOSE: Take the missed dose as soon as you remember. Skip the missed dose if your next dose is less than 2 hours away. Do not take extra medicine to make up the missed dose.
OVERDOSE: Seek emergency medical attention or call the Poison Help line at 1-800-222-1222.
Overdose symptoms may include nausea and vomiting.
WHAT TO AVOID WHILE TAKING TAMIFLU: Do not use a nasal flu vaccine (FluMist) within 48 hours after taking Tamiflu. Oseltamivir may interfere with the drug action of FluMist, making the vaccine less effective. Follow your doctor’s instructions.
OTHER DRUGS THAT WILL AFFECT TAMIFLU: There may be other drugs that can interact with Tamiflu. Tell your doctor about all medications you use. This includes prescription, over-the-counter, vitamin, and herbal products. Do not start a new medication without telling your doctor.
