HIV Pre-Exposure Prophylaxis (PrEP)

 

HIV PrEP or Pre-exposure prophylaxis or PrEP can help reduced the risk of HIV infection.

 

What Is PrEP?

Pre-exposure prophylaxis or PrEP is a type of medication that, when taken as prescribed, can prevent HIV infection. This medication is only suitable for those who do not have HIV but are at higher risk for HIV infection.

PrEP helps to reduce the risk of contracting HIV.

At the moment, two medications have been approved for PrEP. When taken regularly, they are both effective at reducing the risk of transmission of HIV.

 

How Does PrEP Work in HIV Prevention?

The two medications used for PrEP belong to a group of antiviral drugs called nucleoside/nucleotide reverse transcriptase inhibitors (NRTls). These drugs work by preventing the process of multiplication by the HIV virus.

 

Why do you need to see a doctor before PrEP?

Before you start PrEP, it is advised that you see a doctor and get tested for HIV. It is important that you are negative for HIV before starting PrEP. On top of that, the doctor will also advise you to do a blood test to check your liver and kidney function to make sure they are normal.

For subsequent follow-ups, You are advised to see the doctor every three months for HIV and also check for common STDs like syphilis, chlamydia, and gonorrhoea.

If you did not test for HIV before starting PrEP and were later found to be HIV positive while taking PrEP, you may develop drug resistance, and this may affect the treatment of your HIV infection.
