What is the mechanism of action of antiretroviral drugs?
Antiretroviral drugs act by interfering with vital viral replication processes and are classified according to the step they inhibit in the viral life-cycle (Figure 1).
What happens when you take antiretroviral?
Antiretroviral therapy keeps HIV from making copies of itself. When a person living with HIV begins an antiretroviral treatment regimen, their viral load drops. For almost everyone who starts taking their HIV medication daily as prescribed, viral load will drop to an undetectable level in six months or less.
How do antiretroviral drugs work answers?
Antiretroviral drugs do not kill the virus; rather, they block different stages of the virus’s life cycle. By doing so, the virus is unable to replicate and make copies of itself.
What is the success rate of antiretroviral therapy?
At six months, overall viral suppression was 74.6%, being higher among patients who used Single Tablet Regimen (80.6%, p = 0.04). At twelve months, 83.2% of patients reached viral suppression, with no difference between groups (p = 0.93).
What are the signs of a person taking Arvs?
Side effects from antiretroviral HIV drugs can include appetite loss, diarrhea, fatigue, and mood changes. However, not sticking to a treatment plan can cause the virus to become resistant to drugs and harder to treat.
What are the signs of high viral load?
As viral load increases, this high level of viral activity produces symptoms in up to 80% people. These seroconversion symptoms include night sweats, fevers, weakness and tiredness and, more rarely, mouth ulcers. The immune system reacts to viral load in the blood by producing antibodies to fight HIV.
What is the main reason for antiretroviral therapy?
ART reduces mortality and morbidity rates among HIV-infected people, and improves their quality of life. The benefits of ART also include the prevention of HIV transmission by suppressing HIV replication in persons living with the virus.
How long can a person on Arvs live?
However, that number rose to 54.9 years for the most recent combination antiretroviral era. Researchers also concluded that people with HIV with higher education had a similar life expectancy to the general population.

Is antiretroviral therapy lifelong?
ART is a lifelong therapy that should be commenced in consultation with an HIV specialist.
How long must a patient continue antiretroviral drug therapy?
A major challenge of ART is that treatment must be continuous to receive benefits and in most cases requires a lifelong commitment. Many factors can affect a patient’s ability to sustain treatment and may lead to ART discontinuation. Treatment interruptions can be planned or unplanned, short or long term, or permanent.
Is it good to take antiretroviral?
People with HIV who take HIV medicine as prescribed and get and keep an undetectable viral load can live long and healthy lives and will not transmit HIV to their HIV-negative partners through sex.
Is it safe to take antiretroviral therapy?
Treatment with HIV medicines is called antiretroviral therapy (ART). ART is recommended for everyone with HIV, and people with HIV should start ART as soon as possible.

What body changes are caused by ARVs?
Lipodystrophy, or lipo for short, is a collection of body shape changes in people taking antiretroviral medications (ARVs). Lipo- refers to fat, and -dystrophy means bad growth. These changes include fat loss, fat deposits, and metabolic changes. Fat loss occurs in the arms, legs, or face (sunken cheeks).
