Doxycycline (Doxy) PEP and PrEP
As we receive new and up-to-date information about Doxycycline, we are committed to keeping this content current. We appreciate your understanding and encourage you to check back periodically for the latest updates.
What is Doxy?
Doxy, short for Doxycycline, is an antibiotic used to treat various bacterial infections, including sexually transmitted infections (STIs) such as chlamydia and syphilis.
What Is Doxy PEP and Doxy PrEP ?
Doxycycline used as post-exposure prophylaxis (PEP) and pre-exposure prophylaxis (PrEP) are tools that can prevent infection.
When taken before or after coming into contact with a pathogen (like a virus or bacteria), they can decrease a person’s chances of developing infection.
In our context, PEP involves taking medication after sex where we might come into contact with STIs.
PrEP involves taking medication regularly so it is already in our system when we come into contact with STIs.
Is it Available Yet?
As of December 1, 2023, post exposure prophylaxis doxycycline (doxy PEP) is available at no cost for some folks accessing HIV PrEP though the provincial HIV PrEP program offered by the BC Centre for Excellence (BC-CfE).
