A Pfizer C o m p a n y VIRACEPT® (nelfinavir mesylate) Tablets and Oral Powder Information for Patients about VIRACEPT» (Vl-ra-cept) Generic Name: nelfinavir (nel-FIN-na-veer) mesylate For the Treatment of Human Immunodeficiency Virus (HIV) Infection Please read this information carefully before taking VIRACEPT. Also, please read this leaflet each time you renew the prescription, just in case anything has changed. This is a sum m ary and not a replacement for a careful discussion with your doctor. You and your doctor should d iscuss VIRACEPT when you start taking this medication and at regular checkups. You should remain under a doctor's care when taking VIRACEPT and should not change or stop treatment without first talking with your doctor. A lert Find out about m edicines that should NOT be taken with VIRACEPT. Please also read the section “M EDICINES YOU SHOULD NOT TAKE WITH VIRACEPT". WHAT IS VIRACEPT AND HOW DOES IT W ORK? VIRACEPT is used in combination with other antiretroviral drugs in the treatment of people with human immunodeficiency virus (HIV) infection. Infection with HIV leads to the destruction of CD4 T cells, which are important to the immune system. After a large number of CD4 cells have been destroyed, the infected person develops acquired immune deficiency syndrom e (AIDS). VIRACEPT w orks by blocking HIV protease (a protein-cutting enzyme), which is required for HIV to multiply. VIRACEPT has been show n to significantly reduce the amount of HIV in the blood. Although VIRACEPT is not a cure for HIV or AIDS, VIRACEPT can help reduce your risk for death and illness associated with HIV. Patients who took VIRACEPT also had significant increases in the number of CD4 cell count. VIRACEPT should be taken together with other antiretroviral drugs such as Retrovir® (zidovudine, AZT), Eptvir® (lamivudine, 3TC), or Zerit® (stavudine. d4T). Taking VIRACEPT in combination with other antiretroviral drugs reduces the amount of HIV in the body (viral load) and raises CD4 counts. VIRACEPT may be taken by adults, adolescents, and children 2 years of age or older. Studies in infants younger than 2 years of age are now taking place. DOES VIRACEPT CURE HIV OR A ID S? VIRACEPT is not a cure for HIV infection or AIDS. People taking VIRACEPT may still develop opportunistic infections or other conditions associated with HIV infection. Som e of these conditions are pneumonia, herpes virus infections, Mycobacterium avium complex (MAC) infections, and Kaposi’s sarcoma. There is no proof that VIRACEPT can reduce the risk of transmitting HIV to others through sexual contact or blood contamination. WHO SHOULD OR SHOULD NOT TAKE VIRACEPT? Together with your doctor, you need to decide whether VIRACEPT is appropriate for you. In m aking your decision, the following should be considered: Taking the above drugs with VIRACEPT may cause serious and/or life- threatening adverse events. Rifam pin® (for tuberculosis), also known as Rimactane®, Rifadin®, Rifater®, or Rifamate® This drug reduces blood levels of VIRACEPT. Dose reduction required if you take VIRACEPT with: Mycobutin® (rifabutin, for MAC); you will need to take a lower dose of Mycobutin. A change of therapy should be considered if you are taking VIRACEPT with: Phénobarbital Phenytoin (Dilantin® and others) Carbamazepine (Tegretol® and others) D osing in adults (including children 14 years of age and older) Before you take Viagra® (sildenafil) with VIRACEPT, talk to your doctor about possible drug interactions and side effects. If you take Viagra and VIRACEPT together, you may be at increased risk of side effects of Viagra such a s low blood pressure, visual changes, and penile erection lasting more than 4 hours. If an erection lasts longer than 4 hours, you should seek immediate medical assistance to avoid permanent dam age to your penis Your doctor can explain these sym ptom s to you. The recommended adult dose of VIRACEPT is 1250 mg (five tablets) taken two tim es a day or 750 m g (three tablets) taken three tim es a day. Each dose should be taken with a meal or light snack. It is not recommended to take VIRACEPT with the cholesterol-lowering drugs Mevacor® (lovastatin) or Zocor® (simvastatin) because of possible drug interactions. There is also an increased risk of drug interactions between VIRACEPT and Lipitor® (atorvastatin) and Baycol® (cerivastatin); talk to your doctor before you take either of these cholesterol reducing drugs with VIRACEPT. Taking St. John’s wort (hypericum perforatum), an herbal product sold as a dietary supplement, or products containing St. John's wort with VIRACEPT is not recommended. Talk with your doctor if you are taking or are planning to take St. John's wort. Taking St. John’s wort may decrease VIRACEPT levels and lead to increased viral load and possible resistance to VIRACEPT or cross resistance to other antiretroviral drugs. Changes in body fat have been seen in som e patients taking protease inhibitors. These changes may include increased amount of fat in the upper back and neck (“buffalo hump"), breast, and around the trunk. Lo ss of fat from the face, legs and arm s may also happen. The cause and long-term health effects of these conditions are not known at this time.
