Timing for Taking antibiotics commonly used for STI prophylaxis:
Take the prescribed dose within 72 hours after condomless sex as a Postexpostion-Prophylaxe (PEP). Condomless sex means that a condom isn’t used for most of the time. That can be during any type of sex - oral, anal, and vaginal or front-hole sex.
Usage Frequency
Limit the use to once within a 24-hour period. If you accidentally take a second dose too soon, be especially mindful of any side effects. A single dose on Monday can cover the entire weekend if you plan well.
Dietary Considerations
Eating beforehand may help reduce nausea. However, avoid taking foods or supplements rich in calcium, magnesium, zinc, or multivitamins in general 2 hours before and after taking antibiotic for STI prophylaxis to ensure optimal absorption.
