Can You Take Doxycycline and Probiotics Together?

Probiotics taken alongside antibiotics as a class have been linked to a lower likelihood of antibiotic-associated diarrhea -- research is general to antibiotics, not specific to doxycycline.

InformationalEvidence: Moderate

See the full Doxycycline page and Probiotics page for other reviewed interactions and reference information.

What the interaction means

NCCIH states: "A 2017 review of 17 studies (3,631 total participants) in people who were not hospitalized indicated that giving probiotics to patients along with antibiotics was associated with a decrease of about half in the likelihood of antibiotic-associated diarrhea. However, this conclusion was considered tentative because the quality of the studies was only moderate." Doxycycline's own FDA label does not mention probiotics.

Why it may happen

Not specified beyond the general association between probiotic use and reduced antibiotic-associated diarrhea across antibiotics as a class.

Practical context

This finding comes from research on antibiotics generally, not a doxycycline-specific study -- it is presented here as informational context for anyone taking doxycycline, not a doxycycline-specific claim. No documented safety caution or spacing requirement was found; if spacing between a specific probiotic product and an antibiotic dose is recommended, that would typically come from the specific product's own labeling.
