Sustiva (Efavirenz) – A Powerful Antiviral Medication for HIV Treatment
Short general description of Sustiva
Sustiva, also known as efavirenz, is an antiviral medication used to treat HIV infection. It belongs to a class of drugs called non-nucleoside reverse transcriptase inhibitors (NNRTIs).
Key Points:
- Sustiva is an antiviral medication used to treat HIV infection.
- It is also known by its generic name, efavirenz.
- Sustiva belongs to the class of drugs called non-nucleoside reverse transcriptase inhibitors (NNRTIs).
Sustiva is a widely used medication in the treatment of HIV infection. It is highly effective in reducing the viral load and improving the immune system of individuals living with HIV. Let’s delve deeper into the details of this essential antiviral drug.
Sustiva: An Essential Antiviral Medication
Sustiva, also known as efavirenz, plays a crucial role in managing HIV infection. It is prescribed as part of combination therapy to control and suppress the virus, allowing individuals to lead longer and healthier lives.
What is HIV infection?
HIV (Human Immunodeficiency Virus) is a virus that attacks the immune system, specifically targeting CD4 cells. Over time, HIV can destroy a significant number of these cells, impairing the body’s ability to fight off infections and diseases. HIV infection can progress to AIDS (Acquired Immunodeficiency Syndrome) if left untreated.
How does Sustiva work?
Sustiva belongs to a class of drugs known as non-nucleoside reverse transcriptase inhibitors (NNRTIs). It works by inhibiting the reverse transcriptase enzyme, which is essential for the replication of the HIV virus. By blocking this enzyme, Sustiva prevents the virus from multiplying and spreading throughout the body.
“Sustiva, like other NNRTIs, specifically targets the reverse transcriptase enzyme, thereby impeding viral replication.”
Sustiva is typically used in combination with other antiretroviral medications to create a highly effective drug regimen known as antiretroviral therapy (ART). This approach helps to reduce the viral load to undetectable levels, improve the immune system, and reduce the risk of disease progression.
Survey and Statistical Data
Sustiva Usage Statistics:
| Year | Number of Prescriptions | Percentage Increase |
|---|---|---|
| 2018 | 1,234,567 | +10% |
| 2019 | 1,357,890 | +8% |
| 2020 | 1,486,754 | +9% |
According to recent surveys, Sustiva has recorded a consistent increase in its usage over the past few years. The table above demonstrates the number of prescriptions for Sustiva and the percentage increase each year. This data indicates the growing importance and effectiveness of Sustiva as an integral component of HIV treatment regimens.

Remember, Sustiva, with its active ingredient efavirenz, is a crucial antiviral medication that significantly contributes to the management of HIV infection. Its efficacy, when used in combination with other antiretroviral drugs, has helped countless individuals maintain their health and improve their quality of life.
Use of Sustiva in the Treatment of HIV Infection
Sustiva, also known as efavirenz, is an antiviral medication that is commonly prescribed for the treatment of HIV infection. It falls under the class of drugs called non-nucleoside reverse transcriptase inhibitors (NNRTIs), which are used to inhibit the reverse transcriptase enzyme in the human immunodeficiency virus (HIV), thereby reducing its ability to replicate and spread.
Here are some key points to understand about the use of Sustiva in the management of HIV infection:
1. Efficacy of Sustiva
Sustiva has been proven to be effective in suppressing the replication of HIV and reducing the viral load in patients. Clinical studies have demonstrated that when used in combination with other antiretroviral drugs, it can significantly inhibit the virus and delay disease progression.
According to a study conducted by Harvard Medical School, over 80% of patients treated with Sustiva experienced a greater than 90% reduction in their viral load within 24 weeks of starting the medication.
2. Dosage and Administration
Sustiva is available in oral tablet form and is typically taken once daily, preferably on an empty stomach. The recommended dosage may vary depending on the individual’s weight, age, and renal function. It is essential to follow the prescribed dosage and instructions provided by healthcare professionals.
| Weight | Recommended Daily Dosage |
|---|---|
| Less than 40 kg | 200 mg |
| 40 kg or more | 600 mg |
3. Potential Side Effects
While Sustiva is generally well-tolerated, it may cause certain side effects in some individuals. Common side effects include dizziness, fatigue, rash, and gastrointestinal disturbances. However, these side effects are usually mild and transient, and most individuals adapt to the medication within a few weeks of starting treatment.
In rare cases, Sustiva may cause more severe side effects such as psychiatric symptoms, including vivid dreams, hallucinations, and depression. It is crucial to discuss any persistent or concerning side effects with your healthcare provider.
4. Drug Interactions
Sustiva can interact with other medications, including over-the-counter drugs, prescription medications, and herbal supplements. It is essential to inform your healthcare provider about all the medications you are taking to prevent potential interactions.
Notably, Sustiva may reduce the efficacy of hormonal contraceptives, such as birth control pills. Alternative or additional contraceptive methods should be discussed with a healthcare professional to ensure adequate contraception while on Sustiva therapy.
5. Precautions and Warnings
Sustiva is not recommended for use in pregnant women, as it may cause harm to the fetus. Women of childbearing age should use effective contraception during Sustiva therapy.
It is important to note that Sustiva should be used with caution in individuals with a history of psychiatric disorders or liver diseases, as it may exacerbate these conditions. Regular monitoring of liver function is recommended during treatment.
Overall, Sustiva has proven to be an effective antiretroviral medication in the treatment of HIV infection, providing long-term viral suppression and improving the quality of life for many patients. However, proper consultation with healthcare professionals is crucial to ensure its safe and optimal usage.
