Antiviral drugs for hiv-HIV antiretroviral drugs: Types and side effects

An undetectable viral load means that the level of HIV in the blood is too low to be detected by a viral load test. Overall, the benefits of HIV medicines far outweigh the risk of side effects. In addition, newer HIV regimens cause fewer side effects than regimens used in the past. HIV attacks and destroys the infection-fighting CD4 cells of the immune system. Loss of CD4 cells makes it hard for the body to fight off infections and certain HIV-related cancers.

HIV treatment involves taking medicines that slow the progression of the virus in your body.

  • The main treatment for HIV is a class of drugs called antiretrovirals.
  • Antiviral drugs are a class of medication used specifically for treating viral infections rather than bacterial ones.
  • HIV targets the immune system and invades white blood cells called T-cells.

HIV targets the immune system and invades white blood cells called T-cells. These are cells that fight infection. After the virus invades these cells, it replicates makes copies of itself. Then, the cells explode. They release many viral cells that go on to invade other cells in the body. Currently, there is no known cure for HIV.

However, medications can help people living with HIV manage the condition and live healthy lives. These drugs work by stopping HIV from replicating. Here is a list of drugs that are currently approved by the U.

There are many different classes of drugs used to treat HIV. This decision will depend on their viral load and strain, as well as on how severe their case is and how far it has spread. It also helps prevent resistance to the drugs being used. Combination drugs combine medications from different classes into one drug form. The drugs are combined to make a complete HIV regimen. This type of regimen is usually used to treat people who have never taken HIV medications before.

Integrase inhibitors are a class of medication that stops the action of integrase enzyme. This is a viral enzyme that HIV uses to infect T-cells. Integrase inhibitors are usually among the first HIV drugs used in people who have recently contracted HIV because they work well and have minimal side effects.

Examples of these drugs include:. Several combinations of these drugs are also available. These drugs also have other actions that prevent HIV from replicating in the body.

Examples of NRTIs include:. Some NRTIs are rarely used and will be discontinued by the manufacturer by These drugs include:. These drugs work in a similar way to NRTIs. They stop the virus from replicating itself in your body. Protease inhibitors work by binding to protease. This is a protein that HIV needs to replicate in the body. Some protease inhibitors are only approved by the FDA to treat hepatitis C, but these are not the same as those used to treat HIV infection.

Entry inhibitors are another class of HIV medication. HIV needs a host T-cell in order to make copies of itself. These drugs block the virus from entering a host T-cell.

This prevents the virus from replicating itself. An example of an entry inhibitor is:. An example of this type of drug includes:. CYP3A are enzymes that protect liver and gastrointestinal health. These HIV drugs include protease inhibitors and certain integrase inhibitors. Examples of CYP3A inhibitors include:. Because HIV affects the immune system, researchers are studying ways that biological drugs can prevent viral replication. Certain immune-based treatments have been successful in some people in clinical trials and are currently being researched.

They would be used along with other HIV medications. An example of an immune-based therapy is ibalizumab. This drug is an entry inhibitor. It prevents HIV from entering certain immune cells.

You may have side effects for several weeks after starting a new medication. If these side effects get worse or last longer than a few weeks, talk to your doctor. Your doctor may suggest ways to ease your side effects, or they may prescribe you a different drug.

Less often, HIV drugs can cause serious or long-term side effects. This medication list is a brief overview of the types of drugs that are available to treat HIV.

Antiretroviral drugs used in the treatment of HIV infection | FDA

HIV treatment involves taking medicines that slow the progression of the virus in your body. HIV is a type of virus called a retrovirus, and the combination of drugs used to treat it is called antiretroviral therapy ART. ART must be taken every day, exactly as your health care provider prescribes. Getting and staying on HIV treatment because it reduces the amount of HIV in your blood also called the viral load to a very low level. This keeps you healthy and prevents illness. There is also a major prevention benefit.

This is called treatment as prevention. If left untreated, HIV attacks your immune system and can allow different types of life-threatening infections and cancers to develop. If your CD4 cell count falls below a certain level, you are at risk of getting an opportunistic infection. Your health care provider may prescribe medicines to prevent certain infections. Treatment guidelines from the U. If you delay treatment, the virus will continue to harm your immune system and put you at higher risk for developing opportunistic infections that can be life threatening.

However, not everyone experiences side effects from ART. The HIV medications used today have fewer side effects, fewer people experience them, and they are less severe than in the past.

Side effects can differ for each type of ART medicine and from person to person. Some side effects can occur once you start a medicine and may only last a few days or weeks.

Other side effects can start later and last longer. If you experience side effects that are severe or make you want to stop taking your HIV medication, talk to your health care provider or pharmacist before you miss any doses or stop taking the medication. Skipping doses or starting and stopping medication can lead to drug resistance , which can harm your health and limit your future treatment options. And be aware; HIV medicines also may cause different side effects in women than men. If side effects make you want to skip taking your medications sometimes or stop taking them altogether, talk to your health care provider or pharmacist right away to find solutions that work for you.

Your health care provider may prescribe medicines to reduce or eliminate side effects or may recommend changing your medication to another type of ART that might work better for you. Drug resistance can be a cause of treatment failure for people living with HIV.

As HIV multiplies in the body, it sometimes mutates changes form and produces variations of itself. Drug resistance can cause HIV treatment to fail. Drug-resistant HIV also can spread from person to person. Taking HIV medication every day, exactly as prescribed helps prevent drug resistance. Content Source: HIV.

Also included is information about campaigns related to the prevention and diagnosis of hepatitis B and C. El VIH es una amenaza de salud grave para las comunidades latinas, quienes se encuentran en gran desventaja respecto de la incidencia de esta enfermedad en los Estados Unidos.
