Dovato is an antiviral medicine that prevents HIV from multiplying in your body. Individuals weighing at least 40 kilograms (approximately 88 pounds) and not previously treated for HIV should be considered for this program. Patients with HIV-1 infection are primarily prescribed this medication to treat their infection. It is a treatment option for people with HIV who have not already received antiretroviral therapy.

Two drugs are used in this regimen: dolutegravir and lamivudine, which both suppress the virus and slow its progression. Dolutegravir is an integrase inhibitor that prevents viral DNA from being integrated into the host cell’s DNA. Meanwhile, lamivudine inhibits viral RNA transcription into DNA by inhibiting nucleoside reverse transcriptase. As a result, the virus’s ability to reproduce and multiply is effectively curtailed, and viral load is significantly reduced. By reducing viral loads in the body, Dovato helps to strengthen the immune system and prevent infection from spreading. By targeting HIV at its core, Dovato allows HIV to be managed and controlled.

HIV infection cannot be cured with this medication. It is essential that you continue to take all HIV medications exactly as prescribed by your doctor to reduce your risk of spreading HIV disease to others. As directed by your doctor, use an effective barrier method (latex or polyurethane condoms/dental dams) during sexual activity. Items (such as needles/syringes, toothbrushes, and razors) that may have come into contact with blood or other body fluids should not be shared. For more information, talk to your doctor or one of our pharmacists.
