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 Throw away any medication that is out of date.

What side effects may occur?

Side effects cannot be anticipated. If any develop or change in intensity, inform your doctor as soon as possible. Only your doctor can determine if it is safe for you to continue taking Viread.

• More common side effects may include:
  Abdominal pain, diarrhea, gas, headache, loss of appetite, nausea, vomiting, weakness
