See VOCABRIA and REKAMBYS SmPC's for important interactions, contraindications, warnings and precautions, adverse and severe events.[1,2]

  • Patient-related factors

    General Information

    VOCABRIA + REKAMBYS should not be administered with other antiretroviral medicinal products for HIV-1[1,2]

    Virologic suppression[1,2]

    • VOCABRIA + REKAMBYS should only be prescribed in virologically suppressed adults, i.e. those with HIV-1 RNA <50 copies/mL

    Adherence to appointments[1,2]

    • Patients need to be able to adhere and agree to required injection appointments prior to starting long-acting therapy

    Use in pregnancy[1,2]

    • There are limited data on the use of VOCABRIA + REKAMBYS in pregnancy so it is not recommended unless the expected benefit justifies the potential risk to the foetus. VOCABRIA + REKAMBYS has been detected in systemic circulation for up to 4 years after an injection in some patients; consideration should be given to the potential for foetal exposure

    Patients with hepatitis B virus (HBV) / hepatitis C virus (HCV) co-infection or hepatic impairment[1,2]

    • Patients with HBV were excluded from studies with VOCABRIA + REKAMBYS. Initiating VOCABRIA + REKAMBYS in patients with HBV is not recommended
    • Limited data are available in patients with HCV co-infection. Monitoring of liver function is recommended in patients with HCV co-infection
    • VOCABRIA + REKAMBYS is not recommended in patients with severe hepatic impairment, while caution is advised in patients with moderate hepatic impairment

    Drugs causing QT prolongation[2]

    • At the recommended dose, oral rilpivirine is not associated with a clinically relevant effect on QTc. Nevertheless, VOCABRIA + REKAMBYS should be used with caution when co-administered with a medicinal product with a known risk of Torsade de Pointes

    Patients on anticoagulation therapy[3]

    • Intramuscular injections are generally not recommended for patients taking long-term anticoagulation therapy
  • Injections and ongoing monitoring

    Post-injection reactions[2]

    • Partial intravenous administration may result in rapid, serious post-injection reactions
    • These events were very rare in clinical trials and began to resolve within a few minutes after the injection. Observe patients briefly for 10 minutes after the injections for any post-injection reactions

    Hypersensitivity reactions[1,2]

    • Hypersensitivity reactions have been reported in association with VOCABRIA. VOCABRIA and other suspected medicinal products should be discontinued immediately, should signs or symptoms of hypersensitivity develop

    Additional monitoring[1,2]

    • Monitoring of liver chemistries is recommended, and treatment with VOCABRIA + REKAMBYS should be discontinued if hepatotoxicity is suspected
    • Monitoring of liver function is recommended in patients with hepatitis C co-infection
    • Clinical monitoring is recommended for patients on methadone, as methadone maintenance therapy may need to be adjusted
    • VOCABRIA + REKAMBYS is not recommended during pregnancy unless the expected benefit justifies the potential risk; however, viral load should be monitored closely if used during pregnancy
  • Drug interactions and contraindications

  • Gastrointestinal (GI) considerations (oral vs long-acting)

GI=gastrointestinal; HBV=hepatitis B virus; HCV=hepatitis C virus; HIV-1=human immunodeficiency virus type 1; OAT=organic anion transporters; pH=power of hydrogen; RNA=ribonucleic acid.
