PATIENT INFORMATION
Patients should be informed that VIRACEPT is not a cure for HIV infection and that they may
continue to acquire illnesses associated with advanced HIV infection, including opportunistic
infections.
Patients should be told that the long-term effects of VIRACEPT are unknown at this time. They
should be told that there is currently no data demonstrating that VIRACEPT therapy can reduce
the risk of transmitting HIV to others through sexual contact or blood contamination.
Patients should be advised to take VIRACEPT every day as prescribed. Patients should not alter
the dose or discontinue therapy without consulting with their doctor. If a dose is missed, patients
should take the dose as soon as possible and then return to their normal schedule. However, if a dose
is skipped, the patient should not double the next dose.
The most frequent adverse event associated with VIRACEPT is diarrhea, which can usually be controlled
with non-prescription drugs, such as loperamide, which slow gastrointestinal motility.
VIRACEPT may interact with some drugs, therefore, patients should be advised to report to their doctor
the use of any other prescription or non-prescription medication.
Patients receiving oral contraceptives should be instructed that alternate or additional contraceptive
measures should be used during therapy with VIRACEPT.
