What is PrEP? How Does it work?

PrEP stands for pre-exposure prophylaxis. A drug given to prevent infection with the human immunodeficiency virus (HIV). “Pre” means taken before exposure to the virus. “Exposure” represents actual contact with the virus. This is in contrast to PEP, which is used as an emergency treatment for potential viral exposure. “Prevention” means measures taken to prevent infection before it occurs.

At Allied Pharmacy, we understand your concerns about HIV prevention and transmission. PREP was approved in 2012 and stands for Pre-Exposure Prophylaxis.

How does PrEP help patients?

This drug works by preventing HIV from replicating in the body. PrEP acts as a catalyst that helps the body produce antibodies that help fight diseases caused by bacteria and viruses. After contact with the virus, tenofovir and emtricitabine block the enzymes the virus needs to replicate. When used correctly, PrEP eliminates the risk of contracting the virus after exposure. There are two ways to take it. 1 tablet daily, 7 days prior to contact, and daily as needed. A patient can take her PrEP on demand, that is, before scheduled sex. The most common side effects are dizziness, nausea and headache. However, side effects often subside after a week.

How does it work to keep people healthy?

 When used correctly, PrEP is highly effective for HIV contacts. Prevents HIV infection in 99% of cases. People who share injections or needles are at increased risk of illness when using drugs. Patients are more likely to fight off an infection if the dosage is taken conscientiously.

An HIV test should be performed before starting PrEP medication. If a patient is infected with HIV, taking the pills increases the likelihood of developing drug resistance. This makes HIV treatment programs less effective. Patients should consult with their healthcare professional before taking PrEP medications.

When should PrEP drugs be used?

Patients who are not HIV infected but are likely to be exposed to the virus in the future are more likely to benefit from PrEP. Drug users and sexually active individuals who share needles are good candidates for this drug. The risk of HIV infection increases in a number of situations, including:

  • sexual intercourse with an infected person
  • have multiple sexual partners
  • sharing needles or syringes with an infected person
  • have other sexually transmitted infections, such as herpes or gonorrhea
  • intercourse with someone who is already infected

If any of these risk factors apply to your situation, your health care professional can administer her PrEP medication. If you plan to become pregnant from an infected person, use PrEP to prevent transmission during pregnancy and breastfeeding. Talking to your doctor before treatment is the best way to use this medicine.

If you think you are a candidate for PrEP medication, please contact the Washington Institute of Health to make an appointment. Our team of caring and caring providers wants to work with you and support you in making the best decisions for your care and health.
