Drug & supplement interaction

Yogurt + Lisdexamfetamine

Lisdexamfetamine brand name: Vyvanse.

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 Yogurt and Lisdexamfetamine 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

Yogurt and Lisdexamfetamine

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 Lisdexamfetamine and Yogurt 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 Lisdexamfetamine

Interactions in our licensed database are recorded against drug classes, not just single drug names. Lisdexamfetamine is filed under 6 classifications — including amphetamines, stimulant drugs, serotonergic drugs. Yogurt has documented interactions with 3 drug classes — the most serious being ciprofloxacin (cipro) (moderate), tetracycline antibiotics (moderate) and nilotinib (tasigna) (minor) — and none of Lisdexamfetamine’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.

Keep it in perspective

What to actually watch for

No Interaction Found — But Data Suggests Yogurt and Lisdexamfetamine 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. One of them is worth acting on rather than waiting out — marked below.

Special populations

Yogurt in Pregnancy & Breastfeeding

Pregnancy Likely Safe

When consumed in amounts commonly found in foods.

Pregnancy Possibly Safe

When used intravaginally. A small clinical study in pregnancy reported no adverse reactions.

Lactation Likely Safe

When used in amounts commonly found in foods. There is insufficient reliable information available about the safety of the intravaginal use of yogurt during breast-feeding.

Overlapping uses

What Lisdexamfetamine Is Prescribed For, and What Yogurt Has Been Studied For

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

Lisdexamfetamine is prescribed for: Lisdexamfetamine treats Attention Deficit Hyperactivity Disorder (ADHD) in adults and children age 6 and older. It is also approved to treat moderate to severe binge eating disorder (BED) in adults. It is not approved or recommended for weight loss, and its safety and effectiveness for treating obesity have not been established. It is not recommended in children under 6 years old.

Yogurt has been studied for:

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

    Yogurt for obesity

    It is unclear if eating yogurt reduces the risk of obesity in adults or children; the available research is limited and conflicting.

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 Lisdexamfetamine on your own; if you are taking Yogurt for the same health topic, tell your prescriber, especially if the medicine is being adjusted to a target.

About Yogurt

What is Yogurt?

  • Digestive health
  • Restoring gut bacteria after antibiotics
  • Vaginal yeast or bacterial balance
  • Source of protein and calcium
  • General immune and gut support

Yogurt is a fermented dairy food that often contains live bacteria (probiotics) and provides protein, calcium, and other nutrients. For most healthy people it is a safe, nutritious food, and some yogurts with live cultures may help with digestion and gut balance, though evidence varies by strain and condition. If you are lactose intolerant, have a milk allergy, or have a weakened immune system, talk to your pharmacist or doctor first.

Fermented milk product (made with live bacterial cultures) · Plain yogurt, Greek yogurt, drinkable yogurt (kefir-style), probiotic yogurt, dairy-free yogurt alternatives

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

Yogurt: dosing

There is no official "dose" for yogurt because it is a food, not a standardized medicine. The amount and type of live bacteria can vary widely from product to product, and many people simply eat one or more servings a day as part of a healthy diet.If you are using yogurt specifically for its probiotic content, look for a label that says "live and active cultures" and check whether the strains are listed. There is no proven "best" amount for any health condition. If you want a specific probiotic strain or dose, a standardized probiotic supplement may be more reliable.

Taking Yogurt and Lisdexamfetamine Together: Common Questions

Is it safe to take Yogurt with Lisdexamfetamine?
We do not list a known interaction between Yogurt and Lisdexamfetamine. 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 Yogurt and Lisdexamfetamine have any of the same side effects?
Yes — our sources link each of them separately to 6 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 Yogurt and Lisdexamfetamine 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 Yogurt in each. That is a conversation for your prescriber, especially if Lisdexamfetamine is being adjusted to a target.
How was the Yogurt and Lisdexamfetamine combination checked?
Interactions in our licensed database are recorded against drug classes. Lisdexamfetamine is filed under 6 classifications, and Yogurt has documented interactions with 3 drug classes — none of Lisdexamfetamine'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 Yogurt interact with any other medications?
Yes. Yogurt has 22 documented drug interactions in our database — Lisdexamfetamine 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 Lisdexamfetamine interact with any supplements?
Yes. Lisdexamfetamine has documented interactions with 126 supplements in our database — Yogurt is not one of them. The Lisdexamfetamine interaction page linked on this page lists every one, ranked by severity.
