What is the most important information I should know about nelfinavir (Viracept)?
A European version of nelfinavir was found to have high levels of an impurity known to cause cancer in animals. Nelfinavir in the U.S. was found to have lower levels of the impurity, which is created during the manufacturing process but can be minimized.
It is not known whether this impurity has caused harm to anyone taking nelfinavir, and it is important to keep treating your condition. Children and pregnant women should not take nelfinavir as a "first-line" treatment. If you already take nelfinavir your doctor may recommend that you keep taking it. Do not stop taking nelfinavir or change your dose without your doctor's advice.
Do not take nelfinavir with amiodarone (Cordarone, Pacerone), quinidine (Quinaglute, Quinidex), pimozide (Orap), midazolam (Versed), triazolam (Halcion), or an ergot medicine such as Ergomar, Cafergot, Wigraine, D.H.E. 45, Migranal, or Methergine. These drugs can cause life-threatening side effects if you use them while you are taking nelfinavir.
There are many other medicines that can interact with nelfinavir. Tell your doctor about all the prescription and over-the-counter medications you use. This includes vitamins, minerals, herbal products, and drugs prescribed by other doctors.
Taking this medication will not prevent you from passing HIV to other people. Talk with your doctor about safe methods of preventing HIV transmission during sex.
