What kind of interaction is it?

Timing-sensitive: the two substances can be taken on the same day but should be separated by a minimum time window.

Is this interaction backed by published research?

Yes. NutriStack lists 1 citation row for the Dicloxacillin + Probiotics pair, each linking to PubMed by PMID where available. Full sourcing methodology at https://nutristackapp.com/methodology/interactions.

Dicloxacillin + Probiotics

Q: Can I take Dicloxacillin and Probiotics together?

Yes, if you separate them in time. Dicloxacillin and Probiotics have a documented timing-sensitive interaction. Dicloxacillin can suppress or kill bacterial probiotic organisms if taken at the same time, although selected probiotics may lower antibiotic-associated diarrhea risk.

Q: How does this affect a NutriStack Stack Score?

-5 to your Stack Score per scored timing-sensitive row.

Timing SensitiveModerate evidence

What is happening. Dicloxacillin can suppress or kill bacterial probiotic organisms if taken at the same time, although selected probiotics may lower antibiotic-associated diarrhea risk.

Mechanism. Antibacterial exposure can reduce viable probiotic colony counts; the benefit is prevention of dysbiosis, not increased antibiotic efficacy.

Recommendation. Separate probiotic doses from the antibiotic by at least 2 hours when feasible; avoid probiotic use in severely immunocompromised patients or patients with central lines unless clinician-directed.

Stack Score

How it moves the number.

Effect on the composite score

If both Dicloxacillin and Probiotics are in the same stack, this pair applies −5 to your Stack Score (per scored timing-sensitive row).
