Brand
name: Tamiflu
Pronounced: TAM-ih-floo
Generic name: Oseltamivir phosphate , ANTIFLU ( Generic Tamiflu )
Why is Tamiflu prescribed?
Tamiflu speeds recovery from the flu. When started during the first
2 days of the illness, it hastens improvement by at least a day. It
also can prevent the flu if treatment is started within 2 days after
exposure to a flu victim. Tamiflu is one of a new class of antiviral
drugs called neuraminidase inhibitors.
As the flu virus takes hold in the body, it forms new copies of itself
and spreads from cell to cell. Neuraminidase inhibitors fight the virus
by preventing the release of new copies from infected cells. The other
drug in this class, Relenza, is taken by inhalation. Tamiflu is taken
in liquid or capsule form.
Most important fact about Tamiflu
Tamiflu can prevent the flu as long as you continue taking this medication,
but getting a yearly flu shot is still the best way of avoiding the
disease entirely. For older adults, those in high-risk situations such
as health-care work, and people with an immune deficiency or respiratory
disease, vaccination remains a must.
How should you take Tamiflu without prescriptions?
To provide any benefit, Tamiflu must be started within two days of
the onset of symptoms, or exposure to the flu. If you have the flu,
continue taking it twice daily for 5 days, even if you start to feel
better. To prevent the flu, take it once a day for at least 7 days.
Protection lasts as long as you take the drug.
If Tamiflu upsets your stomach, try taking it with food. Shake the
liquid suspension before each use.
If you miss a dose...
Take it as soon as possible. If it is within two hours of your next
dose, skip the missed dose and go back to your regular schedule.
Storage instructions...
Store at room temperature. Keep the blister package dry. Use the liquid
suspension within 10 days. It should be refrigerated, but do not freeze.
