What is Videx?
Videx is an antiviral medication. It is in a category of HIV medicines called reverse transcriptase inhibitors. Videx inhibits the reproduction of HIV in the body.

Videx may also be used for purposes other than those listed in this medication guide.

Before taking Videx, tell your doctor if you
have liver disease;
have kidney disease;
have a history of pancreatitis;
have numbness or tingling in your hands or feet (peripheral neuropathy);
have gout; or
consume alcohol.
You may not be able to take Videx, or you may require a dosage adjustment or special monitoring during treatment if you have any of the conditions listed above.
The chewable and dispersible buffered-tablet forms of Videx contain phenylalanine. Individuals with phenylketonuria (PKU) need to monitor intake of this additive. The buffered tablets also contain sodium, which must be monitored by patients on sodium-restricted diets.
Videx is in the FDA pregnancy category B. This means that it is not expected to be harmful to an unborn baby. Do not take Videx without first talking to your doctor if you are pregnant or could become pregnant. It is very important to treat HIV/ AIDS during pregnancy to reduce the risk of infecting the baby. Talk to your doctor about treatment options.

How should I take Videx?
Take Videx exactly as directed by your doctor. If you do not understand these directions, ask your pharmacist, nurse, or doctor to explain them to you.
Take each dose with a full glass of water.
Take Videx on an empty stomach at least 30 minutes before or 2 hours after a meal.
Chew or crush and swallow the chewable tablets. Alternatively, the chewable tablets can be dissolved in at least 1 ounce of water (for every two tablets). The crushed-tablet suspension is stable at room temperature for up to 1 hour but should be consumed as soon as possible after mixing. If additional flavor is desired, 1 ounce of clear apple juice can be added to this mixture, which should then be consumed immediately.
Mix the buffered powder with at least 4 ounces of water for each packet of powder. This powder must be mixed only with water. Do not add juice or any other liquid. The suspension is good at room temperature for up to 4 hours. However, it should be consumed as soon as possible after mixing.
To ensure that you measure a correct dose, measure the pediatric liquid form of Videx with a special dose-measuring spoon or cup, not with a regular table spoon. If you do not have a dose-measuring device, ask your pharmacist for one. Shake the liquid well before measuring a dose.
Do not crush, chew, or open the Videx EC capsules. Swallow them whole. They have a special coating that must not be broken until it dissolves in the small intestine.
Treatment of HIV/ AIDS almost always requires the use of two or more drugs. If you need to stop taking one of the medicines you are taking for HIV, you should stop all of them until you can talk to your doctor.
