1. Antiretroviral Therapy (ART)

The cornerstone of HIV treatment is Antiretroviral Therapy (ART). This treatment involves taking a combination of HIV medicines daily. ART does not cure HIV but helps control the virus, allowing individuals to live longer, healthier lives. The therapy works by reducing the viral load in the body to undetectable levels, which not only preserves the immune system but also reduces the risk of transmitting the virus to others.

ART typically involves a combination of three or more antiretroviral drugs from different classes. These classes include Nucleoside Reverse Transcriptase Inhibitors (NRTIs), Non-Nucleoside Reverse Transcriptase Inhibitors (NNRTIs), Protease Inhibitors (PIs), Integrase Inhibitors (INIs), and Entry Inhibitors. Each class targets the virus at different stages of its life cycle, making it difficult for HIV to replicate and spread.

2. Single-Tablet Regimens (STRs)

For convenience and adherence, many patients opt for Single-Tablet Regimens (STRs). These regimens combine multiple antiretroviral drugs into a single pill taken once daily. STRs simplify the treatment process, making it easier for patients to adhere to their medication schedule, which is crucial for the effectiveness of the therapy. Some common STRs include Biktarvy, Triumeq, and Genvoya.

3. Long-Acting Injectable Antiretrovirals

A newer option in HIV treatment is long-acting injectable antiretrovirals. These injections are administered every one to two months, offering an alternative to daily oral medication. This option is particularly beneficial for individuals who have difficulty maintaining a daily pill regimen. The first long-acting injectable approved for HIV treatment is Cabenuva, which consists of cabotegravir and rilpivirine.

4. Pre-Exposure Prophylaxis (PrEP)

While PrEP is not a treatment for those already living with HIV, it is a critical option for preventing HIV infection. PrEP involves taking a daily pill, such as Truvada or Descovy, which contains antiretroviral drugs that significantly reduce the risk of contracting HIV. It is particularly recommended for individuals at high risk of HIV exposure, including those with an HIV-positive partner.

5. Post-Exposure Prophylaxis (PEP)

Post-Exposure Prophylaxis (PEP) is an emergency treatment option for individuals who may have been exposed to HIV. PEP involves taking antiretroviral medications within 72 hours of potential exposure, and it is continued for 28 days. PEP is not intended for regular use but can be a lifesaving option in emergency situations.

6. Managing Side Effects and Adherence

While HIV treatment is highly effective, it is not without potential side effects. Common side effects of antiretroviral drugs include nausea, diarrhea, fatigue, and headaches. However, most side effects are manageable and tend to diminish over time. It's crucial for individuals on ART to maintain regular communication with their healthcare provider to address any issues that may arise and to ensure that the treatment remains effective.

Adherence to HIV treatment is vital. Skipping doses or not following the prescribed regimen can lead to drug resistance, making the virus harder to treat. Healthcare providers often work closely with patients to develop strategies for maintaining adherence, such as using pill organizers, setting reminders, and simplifying regimens where possible.
