Can I use doxycycline I have at home?
Maybe you have doxycycline left over from an earlier treatment. Using it as doxyPEP is not a good idea without checking with a doctor first:
- The strength may be different, so you might take the wrong dose.
- It may be past its expiry date.
- Your health or medicines may have changed since it was prescribed.
- Leftover tablets often mean an earlier course was not finished, which is a risk in itself.
When you order doxyPEP, a doctor checks your situation and you get tablets with clear instructions for this exact use.

Frequently asked questions
Is doxyPEP the same as doxycycline?
Yes. DoxyPEP is doxycycline. The difference is how you use it: one 200 mg dose within 72 hours after sex, to prevent an infection instead of treating one.
Can I use doxycycline I already have at home as doxyPEP?
Only after checking with a doctor. The tablets must be the right strength, not expired, and suitable for you. Never split a treatment course to save tablets for later.
Is doxycycline hyclate or monohydrate better for doxyPEP?
Both work at the same dose of 200 mg. Some people find monohydrate slightly easier on the stomach.
Why is doxyPEP a lower dose than other treatments?
DoxyPEP stops a few bacteria right after exposure, so one dose is enough. Treating an established infection takes a full course over several days.
