Agenerase Oral Solution Side Effects Center

Medical Editor: John P. Cunha, DO, FACOEP

Agenerase (amprenavir) Oral Solution is a type of antiviral medication called a protease inhibitor, used to treat HIV, which causes acquired immunodeficiency syndrome (AIDS). It is not a cure for HIV or AIDS. The brand name of this medication is discontinued, but generic versions may be available. Common side effects include nausea, vomiting, diarrhea, stomach pain, numbness or tingling (especially around your mouth), headache, mood changes, or changes in the shape or location of body fat (especially in your arms, legs, face, neck, breasts, and waist).

The recommended dose of Agenerase Oral Solution is based on body weight and age. Agenerase may interact with ritonavir, fluticasone, bepridil, St. John's wort, vitamin E, antibiotics, blood thinners, antidepressants, calcium channel blockers, cholesterol-lowering medicines, drugs that weaken the immune system, heart rhythm medications, other HIV /AIDS medicines, insulin or oral diabetes medications, medicines to treat erectile dysfunction, or seizure medications. Tell your doctor all medications and supplements you use. Agenerase may harm a fetus. Tell your doctor if you are pregnant or plan to become pregnant during treatment. Take all of your HIV medicines as directed to control your infection while you are pregnant. Taking Agenerase together with birth control pills can make Agenerase less effective. Ask your doctor about using a non-hormone method of birth control (such as a condom, diaphragm, spermicide) to prevent pregnancy while taking this drug. Breast milk transmits HIV; do not breastfeed.

Our Agenerase (amprenavir) Oral Solution Side Effects Drug Center provides a comprehensive view of available drug information on the potential side effects when taking this medication.

This is not a complete list of side effects and others may occur. Call your doctor for medical advice about side effects. You may report side effects to FDA at 1-800-FDA-1088.

Agenerase Oral Solution FDA Prescribing Information: Side Effects
(Adverse Reactions)

SIDE EFFECTS

In clinical studies, adverse events leading to amprenavir discontinuation occurred primarily during the first 12 weeks of therapy, and were mostly due to gastrointestinal events (nausea, vomiting, diarrhea, and abdominal pain/discomfort), which were mild to moderate in severity.

Skin rash occurred in 22% of patients treated with amprenavir in studies PROAB3001 and PROAB3006. Rashes were usually maculopapular and of mild or moderate intensity, some with pruritus. Rashes had a median onset of 11 days after amprenavir initiation and a median duration of 10 days. Skin rashes led to amprenavir discontinuation in approximately 3% of patients. In some patients with mild or moderate rash, amprenavir dosing was often continued without interruption; if interrupted, reintroduction of amprenavir generally did not result in rash recurrence.

Severe or life-threatening rash (Grade 3 or 4), including cases of Stevens -Johnson syndrome, occurred in approximately 1% of recipients of AGENERASE (see WARNINGS). Amprenavir therapy should be discontinued for severe or life-threatening rashes and for moderate rashes accompanied by systemic symptoms.

Among amprenavir-treated patients in Phase 3 studies, 2 patients developed de novo diabetes mellitus, 1 patient developed a dorsocervical fat enlargement (buffalo hump), and 9 patients developed fat redistribution.

In studies PROAB3001 and PROAB3006, no increased frequency of Grade 3 or 4 AST, ALT, amylase, or bilirubin elevations was seen compared to controls.

Pediatric Patients: An adverse event profile similar to that seen in adults was seen in pediatric patients.

Concomitant Therapy With Ritonavir: Tables 10 and 11 present adverse clinical events and laboratory abnormalities observed in subjects who received AGENERASE plus ritonavir. Since the trials were small, open- label, of varying duration, and often included different patient populations, direct comparisons to the frequency of events with AGENERASE Capsules alone (see Table 9) cannot be made.
