Brand name:
Viread
Pronounced: VEER-ee-ad
Generic name:
Tenofovir disoproxil fumarate
Why is Viread prescribed?
Viread is one of the drugs prescribed to fight HIV, the human
immunodeficiency virus that causes AIDS (acquired immune deficiency
syndrome). HIV attacks the immune system, slowly destroying the
body's ability to fight off infection. Viread staves off the attack
by interfering with HIV reverse transcriptase, an enzyme the virus
needs to reproduce.
Viread lowers the amount of HIV in the blood and may help
increase the number of T cells, important agents of the immune
system that kill microscopic foreign invaders. It is used in
combination with other anti-HIV drugs when these drugs are not
effective by themselves.
Most important fact about Viread
Viread does not completely eliminate HIV or totally restore the
immune system. There is still a danger of serious infections, so you
should be sure to see your doctor regularly for monitoring and
tests. Notify your doctor immediately of any changes in your general
health.
How should you take Viread?
Be sure to take Viread once a day, every day. Set up a regular
schedule so you won't forget, and always get a new supply when the
drug runs low. If you don't keep the drug in your system, the virus
may develop resistance. Take Viread with meals. Food increases the
amount of Viread that reaches the bloodstream.
--If you miss a dose...
Take it as soon as you remember. If it is almost time for your
next dose, skip the one you missed and go back to your regular
schedule. Do not take 2 doses at once.
--Storage instructions...
Store at room temperature. Throw away any medication that is out
of date.

Why should Viread not be prescribed?

Special warnings about Viread
Remember that Viread does not eliminate HIV from the body. The
infection can still be passed to others through sexual contact or
blood contamination.
Viread should be used with caution if you have liver disease. The
drug has been known to cause liver damage and a buildup of lactic
acid in the blood--a dangerous and potentially fatal condition. If
you are a woman, are overweight, have liver disease, or have used
Viread for a long time you are more likely to develop this
condition. Notify your doctor immediately if you develop any signs
of lactic acid buildup, including shortness of breath, nausea,
vomiting, and stomach/intestinal pain.
If you have a kidney condition, make sure your doctor knows.
People with severe kidney problems shouldn't take Viread.
You should know that some people taking HIV medications
experience a change in fat distribution, with increased fat in the
upper back and neck and loss of fat from the arms, legs, and face.
Viread has not been approved for children.
Possible food and drug interactions when taking Viread

either could be increased, decreased, or altered. It is especially
important to check with your doctor before combining Viread with the
following:

Didanosine (Videx)
Ganciclovir (Cytovene)
Valacyclovir (Valtrex)

Special information if you are pregnant or breastfeeding
Although there's no evidence that Viread can harm a developing
baby, the drug has not been adequately studied during pregnancy. If
you are pregnant or plan to become pregnant, tell your doctor
immediately.
Do not breastfeed. HIV appears in breast milk and can infect the
nursing infant.
