Drug & supplement interaction

Lactobacillus Acidophilus + Glycopyrrolate

Glycopyrrolate brand names: Robinul, Robinul Forte, Glycopyrrolate Injection, Seebri, Lonhala Magnair Kit, and others.

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 Glycopyrrolate 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 Glycopyrrolate

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 Glycopyrrolate 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 Glycopyrrolate

Interactions in our licensed database are recorded against drug classes, not just single drug names. Glycopyrrolate is filed under 2 classifications — anticholinergic drugs, oral drugs. Lactobacillus Acidophilus has documented interactions with 1 drug class — the most serious being antibiotic drugs (moderate) — and none of Glycopyrrolate’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 Glycopyrrolate 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.

  • Itching / A skin rash Additional detail

    Lactobacillus Acidophilus

    “Orally, in one clinical trial, a combination of Lactobacillus acidophilus La-5, Lacticaseibacillus paracasei subsp. paracasei F19, and Bifidobacterium animalis subsp. lacltis BB-12 was associated with two cases of rash, one with itching. However, it is not clear if these adverse effects were due to L. acidophilus, other ingredients, the combination, or if the events were idiosyncratic.”

    Glycopyrrolate

    Listed in the ADVERSE REACTIONS section of the FDA label for Glycopyrrolate. Read the label on DailyMed ›

Reported for Lactobacillus Acidophilus but not commonly for Glycopyrrolate: stomach upset, stomach pain, bloating or gas and a higher chance of infection.

Effects for Glycopyrrolate 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 19,422 voluntary FDA FAERS reports for Glycopyrrolate 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.

The most serious there right now: Activated Charcoal (major), Henbane (major), Scopolia (major), Angel's Trumpet (moderate) and Bacopa (moderate).

From our pharmacist’s overview on the Glycopyrrolate page

“People take glycopyrrolate (Robinul, Seebri) to calm excessive sweating, drooling, or the airway secretions of COPD, and the 46 supplements on this list warrant real caution, the three rated major above all. Henbane and scopolia carry the same atropine-family alkaloids the drug mimics, so adding them can push dry mouth, racing heart, a…”

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.

Taking Lactobacillus Acidophilus and Glycopyrrolate Together: Common Questions

Is it safe to take Lactobacillus Acidophilus with Glycopyrrolate?
We do not list a known interaction between Lactobacillus Acidophilus and Glycopyrrolate. 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 Glycopyrrolate have any of the same side effects?
Yes — our sources link each of them separately to 2 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.
How was the Lactobacillus Acidophilus and Glycopyrrolate combination checked?
Interactions in our licensed database are recorded against drug classes. Glycopyrrolate is filed under 2 classifications, and Lactobacillus Acidophilus has documented interactions with 1 drug class — none of Glycopyrrolate'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 — Glycopyrrolate 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 Glycopyrrolate interact with any supplements?
Yes. Glycopyrrolate has documented interactions with 46 supplements in our database — Lactobacillus Acidophilus is not one of them. The Glycopyrrolate interaction page linked on this page lists every one, ranked by severity.
