Drug & supplement interaction

Lactobacillus Acidophilus + Sertraline

Sertraline brand name: Zoloft.

No Known Interaction
Medically reviewed by · Updated July 2026 · Pair last verified Sep 13, 2026
The bottom line No known interaction

We found no known interaction between Lactobacillus Acidophilus and Sertraline in our sources. Absence of a documented interaction is not the same as proven safety, and does not guarantee one does not exist. Do not start, stop, or change a medication or supplement based on this page; confirm with your pharmacist or doctor first. Additionally, although there is no interaction, the two are separately associated with some of the same side effects, which would make a new symptom harder to attribute to one or the other.

Interaction report

Lactobacillus Acidophilus and Sertraline

We checked these two against our interaction database. Here is what we found.

No Known Interaction Found

We did not find a documented interaction between Sertraline and Lactobacillus Acidophilus in our sources. This does not guarantee that the combination is completely free of risk — there is often limited research on supplements and herbal products, especially around drug interactions.

If you decide to take both, the practical routine is simple: add one new thing at a time and note the date you started it. If the combination is going to disagree with you, it usually shows in the first days to a couple of weeks — and a start date turns “I’ve been feeling off” into something a pharmacist can actually work with. Do not stop a prescribed medicine on your own.

Always talk with your pharmacist or doctor before making changes to your medications or supplements, particularly if you take several medications or have an ongoing health condition.

How we checked

Why No Interaction Is Listed for Sertraline

Interactions in our licensed database are recorded against drug classes, not just single drug names. Sertraline is filed under 13 classifications — including antidepressant drugs, cytochrome p450 2c19 (cyp2c19) inhibitors, cytochrome p450 2c9 (cyp2c9) inhibitors. Lactobacillus Acidophilus has documented interactions with 1 drug class — the most serious being antibiotic drugs (moderate) — and none of Sertraline’s classifications are among them.

Classification data comes from our licensed Natural Medicines dataset. A medication can belong to classes beyond those recorded there, so this describes how the check was run — it is not a safety guarantee.

What to actually watch for

No Interaction Found — But Data Suggests Lactobacillus Acidophilus and Sertraline May Share Several of the Same Side Effects

This is not an interaction. Neither one changes how your body handles the other, and nothing here says they react together. What our sources do show is that each has separately been linked to the effects below — so taking both can make those effects more likely to turn up, and harder to pin on one or the other if they do.

  • Stomach upset / Stomach pain / Diarrhea / Vomiting reported in 4.7% of FDA reports for Sertraline Additional detail

    Lactobacillus Acidophilus

    “Orally, taking Lactobacillus acidophilus in combination with other probiotics may cause gastrointestinal side effects including epigastric discomfort, abdominal pain, dyspepsia, flatulence, bloating, diarrhea, vomiting, and burping; however, these events are uncommon.”

    Sertraline

    Listed in the ADVERSE REACTIONS section of the FDA label for Sertraline, and in voluntary FDA adverse-event reports. Read the label on DailyMed ›

Reported for Lactobacillus Acidophilus but not commonly for Sertraline: bloating or gas, a higher chance of infection, itching and a skin rash.

Effects for Sertraline come from the ADVERSE REACTIONS section of its FDA label; effects for Lactobacillus Acidophilus come from the Natural Medicines adverse-effect record, quoted above. Where a percentage is shown, it is the share of 214,799 voluntary FDA FAERS reports for Sertraline that mention that effect — a reporting proportion, not an incidence rate and not evidence the drug caused it. Wording is matched across sources by our own clinical vocabulary, so treat this as a prompt to pay attention, not a diagnosis.

Overlapping uses

What Sertraline Is Prescribed For, and What Lactobacillus Acidophilus Has Been Studied For

These two come up together because they touch the same health topic — not because they do the same job. Sertraline is a prescription medicine with approved uses on its FDA label. Lactobacillus Acidophilus is a supplement: what follows is what researchers have looked at it for, and how strong that evidence is.

Sertraline is prescribed for: Sertraline treats a range of mental health conditions. All formulations are approved for major depressive disorder (MDD) in adults and obsessive-compulsive disorder (OCD). The oral solution (including Zoloft oral solution) and several tablet formulations are also approved for panic disorder, post-traumatic stress disorder (PTSD), social anxiety disorder, and premenstrual dysphoric disorder (PMDD). For OCD specifically, the capsule formulations and some tablet products are approved for use in adults and children aged 6 and older.

Read the rest of what Sertraline is prescribed for

Sertraline hydrochloride tablets (plain, not film-coated) are approved for OCD in pediatric patients as well. However, sertraline is not approved for major depressive disorder in children — only in adults.

Lactobacillus Acidophilus has been studied for:

  • Depression studied, not established Lactobacillus Acidophilus has been studied for this. Natural Medicines rates the evidence: Insufficient Reliable Evidence To Rate Read what the research shows

    Lactobacillus Acidophilus for depression

    Oral Lactobacillus acidophilus has only been evaluated in combination with other ingredients; its effect when used alone is unclear.

Effectiveness ratings and the research summaries above are the verbatim record from the Natural Medicines database, which grades evidence from “Effective” down to “Insufficient Reliable Evidence To Rate”. A rating below the top of that scale means researchers have looked at it — not that it works, and never that it can stand in for a prescribed medicine. Do not stop or replace Sertraline on your own; if you are taking Lactobacillus Acidophilus for the same health topic, tell your prescriber, especially if the medicine is being adjusted to a target.

About Lactobacillus Acidophilus

What is Lactobacillus Acidophilus?

Lactobacillus Acidophilus
  • Digestive health and balance
  • Diarrhea (including antibiotic-related)
  • Vaginal yeast and bacterial infections
  • Lactose intolerance
  • General immune support

Lactobacillus acidophilus is a 'friendly' bacterium used as a probiotic to support gut and vaginal health. It is generally well tolerated in healthy people, and there is reasonable evidence it may help with certain types of diarrhea, but proof for many other uses is limited. People with weakened immune systems or serious illness should check with a doctor before using it.

Lactobacillus acidophilus · Lactobacillaceae · Live bacterial cultures (the whole microorganism) · Capsules, tablets, chewables, powders, fermented foods (yogurt, kefir), and vaginal suppositories

An interaction check asks whether these two react with each other — it does not ask whether Lactobacillus Acidophilus is a good idea for someone in your situation. Here is what our Lactobacillus Acidophilus record says about it on its own.

Lactobacillus Acidophilus: dosing

There is no single official dose for L. acidophilus. Probiotic doses are usually measured in 'colony-forming units' (CFUs), and products vary widely in strength and strain.The best approach is to follow the directions on the product label, since these are based on the specific strain in that product. A pharmacist can help you choose a reputable product and a reasonable amount.Probiotics are often taken with or near a meal.

About Sertraline

What Is Sertraline Used For?

Brand name: Zoloft

Taking Lactobacillus Acidophilus and Sertraline Together: Common Questions

Is it safe to take Lactobacillus Acidophilus with Sertraline?
We do not list a known interaction between Lactobacillus Acidophilus and Sertraline. That does not guarantee the combination is risk-free, so confirm with your pharmacist or doctor — especially if you take other medications or have a health condition.
Do Lactobacillus Acidophilus and Sertraline have any of the same side effects?
Yes — our sources link each of them separately to 4 of the same effects. That is not an interaction: neither changes how your body handles the other. It does mean that if one of those effects turns up, it can be harder to tell which one is behind it. They are listed on this page with the source behind each.
Are Lactobacillus Acidophilus and Sertraline used for the same thing?
They overlap in purpose, which usually means the real question is whether you need both rather than whether they are safe together. This page lists the shared uses and how strong the evidence is for Lactobacillus Acidophilus in each. That is a conversation for your prescriber, especially if Sertraline is being adjusted to a target.
How was the Lactobacillus Acidophilus and Sertraline combination checked?
Interactions in our licensed database are recorded against drug classes. Sertraline is filed under 13 classifications, and Lactobacillus Acidophilus has documented interactions with 1 drug class — none of Sertraline's classifications are among them. A medication can belong to classes beyond those recorded in our dataset, so this describes how the check was run rather than guaranteeing safety.
Does Lactobacillus Acidophilus interact with any other medications?
Yes. Lactobacillus Acidophilus has 182 documented drug interactions in our database — Sertraline is simply not one of them. If you take anything else, it is worth checking each one; they are all listed on this page.
Does Sertraline interact with any supplements?
Yes. Sertraline has documented interactions with 188 supplements in our database — Lactobacillus Acidophilus is not one of them. The Sertraline interaction page linked on this page lists every one, ranked by severity.
