If the appropriate size TAMIFLU capsules are not available for mixing with sweetened liquids, your Pharmacist may follow the directions in the TAMIFLU Prescribing Information for emergency compounding of an oral suspension.
What to Do if You Miss Your TAMIFLU Dose
If you forget to take your medicine at any time, take the missed dose as soon as you remember, unless it is within 2 hours of your next scheduled dose. Do not take two doses at a time to make up for a missed dose. You can then continue to take TAMIFLU at the usual times.
Taking TAMIFLU with Other Medications
TAMIFLU has been shown to have a minimal chance of negatively interacting with other medications. Your doctor or healthcare professional may recommend taking over–the–counter medications to reduce severity of symptoms while the antiviral action of TAMIFLU takes effect on the flu virus. As with any medication, be sure to discuss with your doctor any over–the–counter or prescription medicines you are currently taking before beginning TAMIFLU therapy. An intranasal flu vaccine like FluMist®* should not be given within 2 weeks before or 48 hours after taking TAMIFLU, unless it is deemed appropriate by your doctor.
Taking TAMIFLU if You Have Kidney Disease
If you have any type of kidney disease, talk to your doctor before starting TAMIFLU therapy. There is a special dosing schedule, as follows, for this group:
- Flu Treatment Dosage — One 75 mg dose, once daily for 5 days
- Flu Prevention Dosage — One 75 mg dose every other day or 30 mg dose once daily
How to Store TAMIFLU
TAMIFLU capsules should be stored at room temperature below 77ºF (25ºC) and kept in a dry place. Refrigerate liquid TAMIFLU at 36º to 46ºF (2º to 8ºC). Do not freeze. As with all medications, keep out of the reach of children.
TAMIFLU is prescribed for treating adults and children 1 year and older with influenza (flu) whose symptoms started within the last day or two. TAMIFLU can also reduce the chance of getting the flu in patients 1 year and older. TAMIFLU is not a substitute for the annual flu vaccinations (you should still get the flu shot every year).
Before taking TAMIFLU, tell your doctor if you are pregnant or nursing, or if you have kidney disease, heart disease, respiratory disease, or other serious health conditions. Also, let your doctor know if you are taking any other medications or if you have received nasally administered influenza virus vaccine during the past two weeks.
If you develop an allergic reaction or a severe rash, stop taking TAMIFLU and contact your healthcare professional immediately, as it may be very serious. People with the flu, particularly children and adolescents, may be at an increased risk of self injury and confusion shortly after taking TAMIFLU and should be closely monitored for signs of unusual behavior. A healthcare professional should be contacted immediately if the patient taking TAMIFLU shows any signs of unusual behavior.
The most common side effects are mild to moderate nausea and vomiting.
