What is it and how is it used?

What Viracept is

Viracept contains a medicine called nelfinavir, which is a ?protease inhibitor?. This belongs to a group of medicines called ?anti-retrovirals?.

What Viracept is used for

Viracept is used with other ?anti-retroviral? medicines to:

  • Work against the Human Immunodeficiency Virus (HIV). It helps to reduce the number of HIV particles in your blood.
  • Increase the number of some cells in your blood that help fight infection. These are called CD4 white blood cells. They are particularly reduced in numbers when you have HIV infection. This can lead to an increased risk of many types of infections.

Viracept is not a cure for HIV infection. You may continue to get infections or other illnesses due to your HIV. Treatment with Viracept does not stop you giving HIV to others through contact with blood or sexual contact. Therefore you must keep taking appropriate precautions to avoid giving the virus to others when you are taking Viracept.

What do you have to consider before using it?

Do not take Viracept if:

  • You are allergic to nelfinavir or to any of the other ingredients (listed in Section 6 ?Further information?).
  • You are taking any of the medicines listed in the first part of Section 2 ?Taking other medicines?, ?Do not take Viracept?. Do not take Viracept if any of the above apply to you.

Take special care with Viracept

Check with your doctor or pharmacist before taking Viracept if:

  • You have kidney problems.
  • You have high blood sugar (diabetes).
  • You have a rare blood problem which runs in families called ?haemophilia?.
  • You have liver disease caused by hepatitis B or C. Your doctor may wish to carry out regular blood tests. If any of the above apply to you, or if you are not sure, talk to your doctor or pharmacist before you take Viracept.

Patients with liver disease

Patients with chronic hepatitis B or C and treated with anti-retroviral agents are at increased risk for severe and potentially fatal liver adverse events and may require blood tests for control of liver function. Speak with your doctor if you have a history of liver disease.

Body fat

Combination anti-retroviral therapy may cause changes in body shape due to changes in fat distribution. These may include loss of fat from legs, arms and face, increased fat in the abdomen (belly) and other internal organs, breast enlargement and fatty lumps on the back of the neck (?buffalo hump?). The cause and long-term health effects of these conditions are not known at this time. Contact your doctor if you notice changes in body fat.

Signs of previous Infections

In some patients with advanced HIV infection and a history of opportunistic infection, signs and symptoms of inflammation from previous infections may occur soon after anti-HIV treatment is started. It is believed that these symptoms are due to an improvement in the body?s immune response, enabling the body to fight infections that may have been present with no obvious symptoms. If you notice any symptoms of infection, please inform your doctor immediately.

Bone disease (osteonecrosis)

Some patients taking combination anti-retroviral therapy may develop a bone disease called osteonecrosis (death of bone tissue caused by loss of blood supply to the bone). The length of combination anti-retroviral therapy, corticosteroid use, alcohol consumption, severe immunosuppression, higher body mass index, among others, may be some of the many risk factors for developing this disease. Signs of osteonecrosis are joint stiffness, aches and pains (especially of the hip, knee and shoulder) and difficulty in movement. If you notice any of these symptoms please inform your doctor immediately.

Tell your doctor or pharmacist if you are taking or have recently taken any other medicines. This includes medicines that you buy without a prescription and herbal medicines.
