Although everyone has some risk of being infected by HIV, there are those who are at a substantially higher risk. Those who use intravenous drugs are at risk by sharing needles and those who are in a relationship that is not monogamous might be at a higher risk of exposure as well. PrEP, or Pre-Exposure Prophylaxis, has been shown to prevent HIV and has been shown to be highly effective even in those who are at a much higher risk of exposure. It is a completely safe medication to take and has a low number of mild side effects in some people that will disappear with time.
This medication has been shown in control trials to be extremely effective as long as it is taken properly. The person should be tested and determined to be HIV-negative immediately before beginning the medication. They should take the medication once a day for as long as they have a high risk of exposure. The medication can be taken orally or topically. The medication takes a week to three weeks to be fully effective and will stop being effective as soon as the person stops taking the medication. While the person is taking the medication, they should continue to be tested regularly to ensure the medication is effective and is working properly.
PrEP UK works by blocking the HIV molecules and preventing them from reproducing. It covers the cells in the body with a protective layer that stops the HIV from attaching and using the cells to reproduce. As long as the person continues to take the medication regularly, HIV cannot attach to the cells in the body to reproduce. When they stop taking the medication, however, the cells in their body are no longer protected and they are once again at risk of exposure. When it is taken regularly, it has up to a 92% chance of preventing an HIV infection.
Those who are at a high risk of exposure can talk to their doctor about PrEP for HIV prevention in the UK to see if they are eligible to try this medication. Their doctor can explain how to take the medication, how long the person will need to take the medication to reduce exposure, and help them find a way to ensure they take the medication daily and do not miss any pills. Their doctor can also answer any questions they may have about taking the medication, its effectiveness, or how it works.
