A scientific illustration showing the impact of doxycycline on the gut microbiome. The image includes a representation of the gut with healthy bacteria surrounded by doxycycline antibiotic molecules. A visual cue for antibiotic resistance, such as bacteria developing shields or barriers, is shown to indicate the rise of resistance. The background should include subtle DNA strands to represent genetic changes and a soft, medical color palette to emphasize health and microbiome balance.

Topline:

A new study from UCSF shows that while doxycycline post-exposure prophylaxis (doxy-PEP) helps prevent sexually transmitted infections (STIs), it also has an impact on gut health. Frequent use of the antibiotic led to increased antibiotic resistance in gut bacteria without drastically changing the overall bacterial community.
