Before taking this medicine
You should not use Videx EC if you are allergic to it. Do not take this medicine together with allopurinol, ribavirin, or stavudine.
Tell your doctor if you have ever had:
-
liver disease or pancreatitis (Videx EC can cause severe or life-threatening effects on your liver or pancreas);
-
kidney disease (or if you are on dialysis);
-
numbness or tingling in your hands or feet, including Raynaud's syndrome; or
-
if you drink large amounts of alcohol.
You may develop lactic acidosis, a dangerous build-up of lactic acid in your blood. This may be more likely if you have other medical conditions, if you've taken HIV medication for a long time, or if you are a woman. Ask your doctor about your risk.
Tell your doctor if you are pregnant, and use your medications properly to control your infection. HIV can be passed to your baby if the virus is not controlled during pregnancy. Your name may be listed on a registry to track any effects of antiviral medicine on the baby.
If you are pregnant, do not take Videx EC together with stavudine. This combination can be very dangerous during pregnancy.
Women with HIV or AIDS should not breast feed a baby. Even if your baby is born without HIV, the virus may be passed to the baby in your breast milk.
How should I take Videx EC?
Follow all directions on your prescription label and read all medication guides or instruction sheets. Use the medicine exactly as directed.
Take Videx EC on an empty stomach, at least 30 minutes before or 2 hours after a meal. Do not take with food.
Shake the oral suspension (liquid) before you measure a dose. Use the dosing syringe provided, or use a medicine dose-measuring device (not a kitchen spoon).
Swallow the capsule whole and do not crush, chew, break, or open it.
Use all HIV medications as directed and read all medication guides you receive. Do not change your dose or dosing schedule without your doctor's advice. Every person with HIV should remain under the care of a doctor.
You will need frequent medical tests. Your vision may also need to be checked.
Store the tablets or capsules at room temperature in a tightly closed container, away from moisture and heat.
Store the liquid in the refrigerator. Throw away any leftover Videx EC liquid that is more than 30 days old.
What happens if I miss a dose?
Take the medicine as soon as you can, but skip the missed dose if it is almost time for your next dose. Do not take two doses at one time.
What happens if I overdose?
Seek emergency medical attention or call the Poison Help line at 1-800-222-1222.
What should I avoid while taking Videx EC?
Do not drink alcohol. It may increase your risk of liver damage or pancreatitis.
Avoid using antacids without your doctor's advice while taking Videx EC. Use only the specific type of antacid your doctor recommends.
Using Videx EC will not prevent your disease from spreading. Do not have unprotected sex or share razors or toothbrushes. Talk with your doctor about safe ways to prevent HIV transmission during sex. Sharing drug or medicine needles is never safe, even for a healthy person.
