Pre-exposure prophylaxis, or PrEP, is an intervention method for people who do not have HIV but who are at substantial risk of getting it to prevent HIV infection by taking a daily pill.

The pill contains two medicines that are used in combination with other medicines to treat HIV. What is unique about this medicine is that it helps keep HIV out, for those whose lifestyles expose them to a daily risk of getting infected with HIV.

Such people groups include those who have unprotected sex, men who have sex with men and commercial sex workers who do not use condoms.

It is recommended that you take PrEP everyday.

The pill does come with side effects too. These include headache, nausea, vomiting, rash, and loss of appetite.  For most people,these will go away after a few weeks.

It is important to get comprehensive professional information on how to use this medicine.

It is recommended to use PrEP in combination with other contraceptives such as condoms to provide even greater protection than when used alone. This will also work to keep away other sexually transmitted diseases.

This recommendation is so that each method can compensate for essential or casual efficacy deficits of the other.

However, this medication calls for high levels of self care and discipline because people who use PrEP must commit to taking the drug every day and seeing their health care provider for follow-up every three months.
