Important information

  • If you are taking Ritonavir Accord in combination with other antiretroviral medicines, it is important that you also carefully read the package leaflet that comes with these medicines. There may be additional information on situations when Ritonavir Accord should be avoided. If you have any further questions on the use of Ritonavir Accord or any of the other medicines, contact your doctor or pharmacist.
  • Ritonavir Accord does not cure HIV infection or AIDS.
  • Those taking Ritonavir Accord may still develop infections or other conditions associated with HIV infection or AIDS. It is therefore important that your doctor monitors you while you are taking Ritonavir Accord.
  • You can still transmit HIV infection while taking this medicine, even though the risk of effective antiretroviral therapy is reduced. Discuss with your doctor the necessary steps to avoid infecting others.

Tell your doctor if you have/had:

  • Previous liver disease.
  • Hepatitis B or C is treated with a combination of antiretroviral drugs because you then have an increased risk of severe and potentially life-threatening reactions due to the effect on the liver. Regular blood tests may be required to check that the liver is functioning properly.
  • Hemophilia, as there are reports of increased bleeding in patients with hemophilia taking this type of medicine ( protease inhibitor ). The reason for this is not known. You may need more medication to help the blood clot ( factor VIII ), to be able to control any bleeding.
  • Impotence (erectile dysfunction), as drugs used to treat erectile dysfunction, can cause low blood pressure and prolonged erection.
  • Diabetes, as there are reports of worsening or development of diabetes (diabetes mellitus) in some patients taking protease inhibitors.
  • Kidney disease, as your doctor may need to check the dose of one of your other medicines (such as protease inhibitors ).

Tell your doctor if you experience:

  • Diarrhea or vomiting that does not improve (lasting), as this may reduce the effect of the medicines you are taking.
  • Nausea, vomiting, or abdominal pain, as this may be a sign of inflammation of the pancreas ( pancreatitis ). Some patients taking Ritonavir Accord may develop serious problems with their pancreas. Tell your doctor as soon as possible if this applies to you. Symptoms of infection –  contact your doctor immediately. Some patients with advanced HIV infection (AIDS) who are starting treatment for HIV may have symptoms from previous infections that they did not know they had. This is probably due to the body’s improved immune response which enables the body to fight these infections.
    In addition to the opportunistic infections, so can autoimmune diseases (a condition that occurs when the immune system attacks healthy body tissue) occur after you start taking medication to treat your HIV infection. Autoimmune diseases can occur several months after starting treatment. If you notice any symptoms of infection or other symptoms such as muscle weakness, weakness starting in the hands and feet and going upwards in the body, palpitations, tremors, or hyperactivity, inform your doctor immediately to get the necessary treatment.
  • Stiffness in joints, pain, and aches (especially hips, knees, and shoulders), and difficulty moving, tell your doctor as this may be a sign of a disease that can destroy bones ( osteonecrosis ). Some patients receiving combination antiretroviral therapy may develop this disease.
  • Muscle aches, soreness, and weakness, especially in combination with antiretroviral therapy that includes protease inhibitors and nucleoside analogs. On rare occasions, these muscle problems have been severe. (See section 4.  Possible side effects ) .
  • Dizziness, fainting, or abnormal heartbeat. Some patients taking Ritonavir Accord may experience electrocardiogram ( ECG ) changes. Tell your doctor if you have a heart defect or conduction disturbances in your heart.
