Injectable PrEP is opening a new direction in HIV prevention due to its effective protection without the need to take medication every day. For many years, oral PrEP has helped millions of people worldwide reduce the risk of HIV infection. However, maintaining daily medication remains a challenge for many. The emergence of injectable PrEP offers an additional flexible option. More discreet and convenient for people at high risk of HIV infection. This is considered an important step forward in the global strategy for HIV control.
What is Injectable PrEP?
PrEP (Pre-Exposure Prophylaxis) is a method that uses medication for pre-exposure prophylaxis to reduce the risk of HIV infection in people who are not infected. Unlike daily oral PrEP, injectable PrEP uses the long-acting active ingredient cabotegravir. Users only need to receive injections according to a schedule rather than remembering to take medication every day. This model helps maintain stable drug levels in the body and significantly reduces the risk of missed doses.
Why is Injectable PrEP considered a new advancement?
No need to take medication every day
One of the common difficulties with oral PrEP is maintaining regular medication use.
Injectable PrEP helps reduce the pressure of remembering medication daily and is suitable for people with busy schedules or who find it difficult to maintain long-term medication habits.
Increased privacy
Many people are concerned that using PrEP medication may lead to misunderstandings or questions about their personal lives.
Injectable PrEP helps reduce these pressures because it does not require carrying medication or taking it frequently.
Better treatment adherence
Regular injections at medical facilities help users be monitored for their health and reduce the risk of missed doses.
Effectiveness of Injectable PrEP in HIV prevention
International studies show that injectable PrEP is highly effective in preventing HIV. In people who use it according to the schedule and are properly monitored. Injectable PrEP significantly reduces the risk of HIV infection through sexual transmission. The high effectiveness of this method is not only due to the drug's effect but also from reducing the risk of missed doses - one of the common reasons for reduced effectiveness of oral PrEP.
Who may be suitable for Injectable PrEP?
Injectable PrEP may be suitable for:
- People who are not infected with HIV
- People at high risk of HIV infection through sexual contact
- People who have difficulty taking medication daily
- People who want a more discreet prevention method
- People who have previously used oral PrEP but found it difficult to maintain regularly
Choosing the appropriate PrEP method should be based on the needs and health status of each individual.
HIV testing is required before using Injectable PrEP
An important principle is that users must have a negative HIV test result before starting injectable PrEP. In addition, regular HIV testing during use should be carried out according to professional guidelines to ensure effective protection and early detection of health issues if any.
The role of PrEP in the HIV prevention strategy
PrEP is currently one of the most effective tools to reduce new HIV infections globally.
When combined with:
- Regular HIV testing
- Condom use
- Early HIV treatment
- Sexual health knowledge
PrEP plays an important role in the goal of reducing HIV transmission in the community.
