Videx EC Precautions

Videx EC may cause serious side effects, including:

  • Swelling of your pancreas (pancreatitis) that may cause death. Pancreatitis can happen at any time during your treatment with Videx EC. Before you start taking Videx EC, tell your healthcare provider if you:
    • have had pancreatitis
    • have advanced HIV (human immunodeficiency virus) infection
    • have kidney problems
    • drink alcoholic beverages
    • take a medicine called Zerit (stavudine)

It is important to call your healthcare provider right away if you have stomach pain, swelling of your stomach, nausea and vomiting, or fever.

  • Build-up of acid in your blood (lactic acidosis). Lactic acidosis must be treated in the hospital as it may cause death. The risk for lactic acidosis may be higher if you:
    • have liver problems
    • are pregnant. There have been deaths reported in pregnant women who get lactic acidosis after taking Videx EC and Zerit (stavudine).
    • are overweight
    • have been treated for a long time with other medicines to treat HIV

It is important to call your healthcare provider right away if you feel weak or tired, have unusual (not normal) muscle pain, have trouble breathing, have stomach pain with nausea and vomiting, feel cold, especially in your arms and legs, feel dizzy or light-headed, or have a fast or irregular heartbeat.

  • Liver problems. Some people (including pregnant women) who have taken Videx EC have had serious liver problems. These problems include liver enlargement (hepatomegaly), fat in the liver (steatosis), liver failure, and high blood pressure in the large vein of the liver (portal hypertension). Severe liver problems can lead to liver transplantation or death in some people taking didanosine. Your healthcare provider should check your liver function while you are taking Videx EC. You should be especially careful if you have a history of heavy alcohol use or liver problems.

It is important to call your healthcare provider right away if you have:

  • yellowing of your skin or the white of your eyes (jaundice)
  • dark urine
  • pain on the right side of your stomach
  • swelling of your stomach
  • easy bruising or bleeding
  • loss of appetite
  • nausea or vomiting
  • vomiting blood or dark colored stools (bowel movements)
  • Vision changes. You should have regular eye exams while you take Videx EC.
  • Peripheral neuropathy. Symptoms include: numbness, tingling, or pain in your hands or feet. This condition is more likely to happen in people who have had it before, in patients taking medicines that affect the nerves, and in people with advanced HIV disease. A child may not notice these symptoms. Ask your child’s healthcare provider for the signs and symptoms of peripheral neuropathy in children.
  • Changes in your immune system (immune reconstitution syndrome). Your immune system may get stronger and begin to fight infections that have been hidden in your body for a long time. Tell your healthcare provider if you start having new or worse symptoms of infection after you start taking HIV medicine.
  • Changes in body fat (fat redistribution). Changes in body fat have been seen in people who take antiretroviral medicines. These changes may include: more fat in or around your upper back and neck (buffalo hump), breasts or chest, trunk, and less fat in your legs, arms, or face.

​Do not take Videx EC if you take:

  • Zyloprim, Lopurin, Aloprim (allopurinol)
  • Copegus, Rebetol, Ribasphere, Ribavirin, Virazole (ribavirin)

Do not drink alcohol while you take Videx EC. Alcohol may increase your risk of getting pain and swelling of your pancreas (pancreatitis) or may damage your liver.

Videx EC Food Interactions

  • have or had persistent numbness, tingling, or pain in the hands or feet (neuropathy)

Tell your healthcare provider about all the medicines you take, including prescription and non-prescription medicines, vitamins and herbal supplements. 

Videx EC and Pregnancy

Tell your doctor if you are pregnant or plan to become pregnant.

The FDA categorizes medications based on safety for use during pregnancy. Five categories - A, B, C, D, and X, are used to classify the possible risks to an unborn baby when a medication is taken during pregnancy.

This medication falls into category B. It is not known if Videx EC will harm your unborn baby. Tell your healthcare provider right away if you become pregnant while taking Videx EC. You and your healthcare provider will decide if you should take Videx EC while you are pregnant.

There is a pregnancy registry for women who take antiviral medicines during pregnancy. The purpose of the registry is to collect information about the health of you and your baby. Talk to your doctor about how you can take part in this registry.

Videx EC and Lactation

Tell your healthcare provider if you are breastfeeding or plan to breastfeed. Do not breastfeed. It is not known if Videx EC can be passed to your baby in your breast milk and whether it could harm your baby. Also, mothers with HIV should not breastfeed because HIV can be passed to the baby in the breast milk.

    Videx EC FDA Warning

    WARNING: PANCREATITIS, LACTIC ACIDOSIS and HEPATOMEGALY with STEATOSIS

    Fatal and nonfatal pancreatitis has occurred during therapy with didanosine used alone or in combination regimens in both treatment-naive and treatment-experienced patients, regardless of degree of immunosuppression. Videx EC should be suspended in patients with suspected pancreatitis and discontinued in patients with confirmed pancreatitis.

    Lactic acidosis and severe hepatomegaly with steatosis, including fatal cases, have been reported with the use of nucleoside analogues alone or in combination, including didanosine and other antiretrovirals. Fatal lactic acidosis has been reported in pregnant women who received the combination of didanosine and stavudine with other antiretroviral agents. The combination of didanosine and stavudine should be used with caution during pregnancy and is recommended only if the potential benefit clearly outweighs the potential risk.
