Atroiza is a combination pill used primarily to treat HIV infection. It contains three antiretroviral drugs: efavirenz, tenofovir disoproxil fumarate, and emtricitabine. These medications work together to suppress the HIV virus in the body, reducing the viral load to very low or undetectable levels, which helps prevent damage to the immune system and allows it to recover and strengthen

. Atroiza is essentially a generic version of Atripla, which is a well-known fixed-dose combination of the same three drugs. It is taken once daily, typically at bedtime on an empty stomach, to minimize side effects such as sleep disturbances, mood changes, and fatigue, mainly related to efavirenz

. While Atroiza effectively treats HIV by suppressing the virus, it is not a cure. Patients must continue taking the medication as prescribed to maintain viral suppression and reduce the risk of HIV-related complications and transmission

. Some countries use the same drug combination for post-exposure prophylaxis (PEP) to prevent HIV infection after potential exposure, but this is not recommended in all regions due to side effect concerns, especially with efavirenz

. In summary, Atroiza is used to treat HIV infection by suppressing the virus, thereby helping to maintain and improve immune system function
