Pre-exposure prophylaxis, or PrEP, is a well-known method used by HIV-negative individuals to reduce the risk of contracting HIV. However, many people wonder what happens if someone who is already HIV positive takes PrEP. Could it still be beneficial, or could it cause complications? In this article, we’ll explore the effects of taking PrEP while HIV positive, offering a clear, evidence-based perspective.
Understanding PrEP: A Quick Overview
PrEP is a preventive treatment that involves taking a daily pill (most commonly a combination of tenofovir and emtricitabine) to lower the risk of contracting HIV. When taken consistently, PrEP can reduce the risk of acquiring HIV by up to 99% in people who are HIV-negative and at high risk of exposure, such as those with an HIV-positive partner or those who inject drugs.
PrEP is effective because it works by suppressing the virus’s ability to replicate in the body, essentially preventing it from establishing a permanent infection if exposed to the virus.
Can Someone Who Is HIV Positive Take PrEP?
In short, taking PrEP while already HIV-positive is neither necessary nor recommended. PrEP is specifically designed for individuals who are at risk of contracting HIV but do not have the virus already. For someone already living with HIV, the standard of care is to use antiretroviral therapy (ART) rather than PrEP.
Why PrEP Is Not For People With HIV
Here are some important reasons why people living with HIV should not take PrEP:
1. PrEP Does Not Treat HIV Infection
PrEP’s main purpose is to prevent the transmission of HIV, not to treat it. If you’re already HIV-positive, PrEP will not be able to control the virus. It lacks the specific combination of drugs needed to suppress the viral load and manage an existing infection.
For managing HIV, doctors prescribe antiretroviral drugs (ART). ART involves a combination of medications that target different stages of the HIV life cycle, aiming to reduce the viral load to undetectable levels. When taken consistently, ART not only protects your health but also helps prevent the transmission of the virus to others—a concept known as “undetectable = untransmittable” (U=U).
2. Potential Drug Interactions
Another reason why taking PrEP while HIV positive is a bad idea is because of the potential drug interactions. PrEP and ART contain overlapping medications (e.g., tenofovir and emtricitabine are found in both PrEP and some ART regimens). Taking PrEP in conjunction with ART could result in an excess of these drugs in the bloodstream, increasing the risk of side effects and possibly affecting the effectiveness of the ART regimen.
This overlap could lead to toxic levels of certain drugs, which could damage your kidneys or bones, two areas already at risk from long-term HIV treatment.
3. PrEP May Mask the Progression of HIV
In some cases, taking PrEP could delay the diagnosis of HIV in people who are already infected. Since PrEP helps reduce the ability of HIV to replicate, it may lower the viral load enough to obscure symptoms and prevent accurate detection through standard tests. This could cause individuals to unknowingly carry a high viral load for longer, increasing the risk of complications and transmission to others.
Why ART is the Better Option for People Living with HIV
While PrEP is not suitable for individuals already living with HIV, antiretroviral therapy (ART) remains the cornerstone of HIV treatment. Here’s why ART is the better option:
1. Viral Suppression
The primary goal of ART is to suppress the HIV virus and reduce its replication to undetectable levels. When HIV is undetectable, it cannot be transmitted to others. ART is highly effective at achieving this goal, allowing people living with HIV to lead healthy lives and maintain a near-normal lifespan.
2. Preventing HIV Complications
Taking ART not only helps reduce the risk of transmitting HIV to others but also prevents the virus from causing further damage to your immune system. Without treatment, HIV can lead to AIDS, a condition in which the immune system is so weakened that the body becomes vulnerable to opportunistic infections and certain cancers. ART slows down this progression and can help prevent these severe complications.
3. Lifelong Management
While there is currently no cure for HIV, ART provides a reliable, long-term solution. Most people living with HIV can maintain an undetectable viral load with a proper treatment regimen. Regular monitoring by a healthcare provider ensures that the treatment remains effective and helps to manage side effects.

Potential Risks of Taking PrEP While HIV Positive
Taking PrEP as an HIV-positive individual could pose several health risks:
1. Drug Toxicity
As mentioned earlier, there is a risk of drug toxicity if you take PrEP and ART together. This could lead to kidney damage, bone density loss, or other complications. These side effects can become more pronounced over time, leading to additional health concerns.
2. Delayed Diagnosis
If you take PrEP unknowingly while being HIV positive, it could delay your diagnosis and treatment. This delay could result in higher levels of viral replication and make your condition more difficult to manage.
3. Decreased Medication Effectiveness
PrEP does not provide the comprehensive antiviral effect needed for managing HIV. ART drugs, on the other hand, are specifically designed to target the virus on multiple fronts, ensuring a more effective treatment.
What Should You Do If You Are HIV Positive and Considering PrEP?
If you are living with HIV, it is crucial to avoid taking PrEP and instead focus on getting the right treatment. Consult your healthcare provider about starting antiretroviral therapy (ART). Your doctor will help you select a treatment plan tailored to your specific needs, monitor your progress, and provide guidance on maintaining a healthy lifestyle.
Here are a few additional tips for managing HIV:
1. Get Regular Testing
Monitoring your viral load and CD4 count is essential for tracking the progress of your treatment and ensuring that your medications are working effectively. Regular testing helps you stay informed about your health status.
2. Focus on Healthy Living
Incorporating a balanced diet, regular exercise, and mental health support into your routine can help you manage the side effects of ART and maintain overall well-being.
3. Understand the Importance of Adherence
For ART to work effectively, you must take your medications exactly as prescribed. Skipping doses can lead to drug resistance, where the virus becomes less responsive to treatment, making it harder to control. Always communicate with your healthcare provider if you experience any difficulties with your treatment plan.
Conclusion: The Bottom Line
PrEP is an effective HIV prevention tool for people who are HIV-negative and at high risk of exposure to the virus. However, if you are already HIV positive, PrEP is not appropriate for you. Instead, you should focus on starting antiretroviral therapy (ART) to effectively manage your condition. ART will help suppress the virus, protect your immune system, and reduce the risk of transmission to others.
Always consult a healthcare provider before starting any treatment, and never self-prescribe medications like PrEP if you are already HIV-positive. With the right care and commitment to treatment, living with HIV can be managed effectively, allowing you to enjoy a healthy, fulfilling life.
