BOXED WARNING: POST TREATMENT ACUTE EXACERBATION OF HEPATITIS B
- Severe acute exacerbations of hepatitis B (HBV) have been reported in patients who are coinfected with HIV-1 and HBV and have discontinued products containing emtricitabine and/or tenofovir disoproxil fumarate (TDF) and may occur with discontinuation of SYMTUZA®.
Action: Monitor hepatic function with both clinical and laboratory follow-up for at least several months in patients who are coinfected with HIV-1 and HBV and discontinue SYMTUZA®. If appropriate, anti-hepatitis B therapy may be warranted.
CONTRAINDICATIONS
- Do not coadminister SYMTUZA® and the following drugs due to the potential for serious and/or life-threatening events or loss of therapeutic effect: alfuzosin, carbamazepine, colchicine (in patients with renal and/or hepatic impairment), dronedarone, elbasvir/grazoprevir, ergot derivatives (such as: dihydroergotamine, ergotamine, methylergonovine), ivabradine, lomitapide, lovastatin, lurasidone, oral midazolam, naloxegol, phenobarbital, phenytoin, pimozide, ranolazine, rifampin, St. John’s wort (Hypericum perforatum), sildenafil for pulmonary arterial hypertension, simvastatin, and triazolam.
