Common Side Effects of Genvoya
Genvoya, a combination HIV treatment with elvitegravir, cobicistat, emtricitabine, and tenofovir alafenamide, most often causes nausea, diarrhea, headache, and fatigue. These affect more than 5% of users in clinical trials and typically improve over time.[1][2]
Serious Side Effects and Warnings
Rare but severe risks include lactic acidosis (symptoms: deep rapid breathing, drowsiness, slow heartbeat), liver problems (jaundice, dark urine), and new or worsening kidney issues (reduced urine, swelling). Bone density loss and immune reconstitution syndrome—where the body fights old infections aggressively—also occur. Stop use and seek immediate care for allergic reactions like rash, fever, or swelling.[1][2][3]
Long-Term Risks Patients Monitor
Over years, users report weight gain, especially abdominal fat, and potential Fanconi syndrome from kidney tubule damage. Osteoporosis risk rises with prolonged use; regular bone scans are advised for at-risk patients.[2][3]
Side Effects in Special Groups
Pregnant users face possible fetal bone or kidney effects—avoid if possible, discuss alternatives with doctors. In those with hepatitis B, stopping Genvoya can trigger liver flares. Children over 2 years (28 kg+) see similar profiles but higher diarrhea rates.[1][3]
How Side Effects Compare to Other HIV Meds
Genvoya has fewer kidney and bone issues than older tenofovir formulations like Viread-based regimens, thanks to its TAF component. But cobicistat interactions raise risks with statins or certain antifungals more than boosted darunavir options.[2]
Managing and Reporting Side Effects
Take with food to cut nausea. Hydrate and monitor labs for kidney/liver function. Report to FDA via MedWatch or 1-800-FDA-1088; most resolve with dose adjustments or switches.[1]
