Since a definitive HIV cure is far from being achieved, experts are counting on the anti-HIV drug to prevent the proliferation of the disease. People who don't have HIV, but are at risk, are advised to take Pre-Exposure Prophylaxis or PrEP.

PrEP serves as an additional option for sexually active individuals to protect themselves from the risk of HIV. In some areas, like in Africa, the use of PrEP are highly advised by their experts to decrease the cases of the sexually transmitted disease.

"It's an ARV drug in the form of a tablet and it's for HIV-negative people. It needs to be taken daily to significantly reduce the chances of getting HIV. It works if people are taking it everyday but they don't need to take PrEP for the rest of their lives - only during the period of their life when they are at a significant risk for HIV, Dr Saiqa Mullick, director of implementation science at the Wits Reproductive Health and HIV Institute told Health-e News.

Although there have been recent concerns raised about the efficiency of such drug, many experts are still convinced of its benefits. Based on a South African National AIDS Council, series of clinical trials can attest to the effectiveness of oral tablets for PrEP in Africa, Asia, Europe, South America and the United States.

Meanwhile, although PrEP is being pushed for massive use in certain high-risk areas. Experts are still suggesting that people should first get tested before using the said anti-HIV pill. PrEP is intended for people with no infection, using it while already infected will not help in treating the disease, according to CitizenTV.

Although the said pill may lower the risk of HIV by up to 90 percent, most experts suggest the use of a condom to complement the pill. It is still well-accepted that the use of a condom is still the best way to prevent HIV infection.
