Serious side effects have been reported with Dovato inclluding the following:

  • Resistant HBV infection. Your healthcare provider will test you for HBV infection before you start treatment with Dovato. If you have HIV-1 and hepatitis B, the hepatitis B virus can change (mutate) during your treatment with Dovato and become harder to treat (resistant). It is not known if Dovato is safe and effective in people who have HIV-1 and HBV infection.
  • Worsening of HBV infection. If you have HIV-1 and HBV infection, your HBV may get worse (flare-up) if you stop taking Dovato. A “flare-up” is when your HBV infection suddenly returns in a worse way than before. Worsening liver disease can be serious and may lead to death.
    • Do not run out of Dovato. Refill your prescription or talk to your healthcare provider before your Dovato is all gone.
    • Do not stop Dovato without first talking to your healthcare provider. If you stop taking Dovato, your healthcare provider will need to check your health often and do blood tests regularly for several months to check your liver.

    • redness or swelling of the eyes
    • swelling of the mouth, face, lips, or tongue
    • problems breathing
  • Liver problems. People with a history of hepatitis B or C virus may have an increased risk of developing new or worsening changes in certain liver tests during treatment with Dovato. Liver problems, including liver failure, have also happened in people without a history of liver disease or other risk factors. Your healthcare provider may do blood tests to check your liver.

Dovato FDA Warning

WARNING: PATIENTS CO-INFECTED WITH HEPATITIS B VIRUS (HBV) AND HUMAN IMMUNODEFICIENCY VIRUS (HIV-1): EMERGENCE OF LAMIVUDINERESISTANT HBV AND EXACERBATIONS OF HBV

All patients with HIV-1 should be tested for the presence of HBV prior to or when initiating DOVATO. Emergence of lamivudine-resistant HBV variants associated with lamivudine-containing antiretroviral regimens has been reported. If DOVATO is used in patients co-infected with HIV-1 and HBV, additional treatment should be considered for appropriate treatment of chronic HBV; otherwise, consider an alternative regimen.

Severe acute exacerbations of HBV have been reported in patients who are co-infected with HIV-1 and HBV and have discontinued lamivudine, a component of DOVATO. Closely monitor hepatic function in these patients and, if appropriate, initiate anti-HBV treatment.
