Drug & supplement interaction

Piracetam + Lisinopril

Lisinopril brand names: Zestril, Prinivil, Qbrelis.

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 Piracetam and Lisinopril 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

Piracetam and Lisinopril

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 Lisinopril and Piracetam 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.

Piracetam safety at a glance

Piracetam overall Use caution It is a drug, not a true dietary supplement, and is unapproved in the U.S. with variable product quality.
Pregnancy Avoid There is not enough safety data, so avoid use during pregnancy.
Breastfeeding Avoid It may pass into breast milk and safety is unknown, so avoid use while breastfeeding.

Safety guidance is general; always confirm with your pharmacist or doctor for your situation.

How we checked

Why No Interaction Is Listed for Lisinopril

Interactions in our licensed database are recorded against drug classes, not just single drug names. Lisinopril is filed under 6 classifications — including ace inhibitors (aceis), antihypertensive drugs, photosensitizing drugs. Piracetam has documented interactions with 1 drug class — the most serious being anticoagulant/antiplatelet drugs (major) — and none of Lisinopril’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 Piracetam and Lisinopril 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. 4 of them are worth acting on rather than waiting out — marked below.

Effects for Lisinopril come from the ADVERSE REACTIONS section of its FDA label; effects for Piracetam come from the Natural Medicines adverse-effect record, quoted above. Where a percentage is shown, it is the share of 313,746 voluntary FDA FAERS reports for Lisinopril 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 Lisinopril Is Prescribed For, and What Piracetam Has Been Studied For

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

Lisinopril is prescribed for: Lisinopril treats high blood pressure (hypertension) in adults and children 6 years and older, and can be used alone or alongside other blood pressure medicines. Lowering blood pressure reduces the risk of strokes and heart attacks. The tablet combination product containing lisinopril and hydrochlorothiazide is specifically indicated for high blood pressure. Lisinopril is also used as an add-on therapy to reduce signs and symptoms of systolic heart failure, and to reduce the risk of death in people who are hemodynamically stable (have reasonably stable circulation) within 24 hours of an acute heart attack (acute myocardial infarction).

Piracetam has been studied for:

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

    Piracetam for stroke

    Given the low-quality and inconclusive findings in the available clinical research, it is unclear which stroke patients, if any, might benefit from oral piracetam.

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

About Piracetam

What is Piracetam?

  • Memory and cognition ('nootropic')
  • Cognitive decline and dementia
  • Myoclonus
  • Dyslexia in children
  • Vertigo

Piracetam is a synthetic 'nootropic' drug studied mainly for cognitive decline, myoclonus, and certain neurological conditions, but evidence for boosting memory in healthy people is weak. It is a prescription medicine in many countries and is not an approved drug or dietary supplement in the United States, so quality and safety of products sold online vary. Talk to a doctor or pharmacist before using it.

Synthetic compound (not plant-derived) · Tablets, capsules, powder, oral solution

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

Piracetam: dosing

There is no established 'supplement' dose for piracetam, and recommended amounts in medical settings vary widely depending on the country and condition being treated. Because it is unapproved in the U.S. They can help you weigh the risks, especially if you have kidney issues or take other medicines. Do not assume that taking more will work better; higher amounts may increase side effects.

Taking Piracetam and Lisinopril Together: Common Questions

Is it safe to take Piracetam with Lisinopril?
We do not list a known interaction between Piracetam and Lisinopril. 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 Piracetam and Lisinopril have any of the same side effects?
Yes — our sources link each of them separately to 10 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 Piracetam and Lisinopril 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 Piracetam in each. That is a conversation for your prescriber, especially if Lisinopril is being adjusted to a target.
How was the Piracetam and Lisinopril combination checked?
Interactions in our licensed database are recorded against drug classes. Lisinopril is filed under 6 classifications, and Piracetam has documented interactions with 1 drug class — none of Lisinopril'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 Piracetam interact with any other medications?
Yes. Piracetam has 122 documented drug interactions in our database — Lisinopril 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 Lisinopril interact with any supplements?
Yes. Lisinopril has documented interactions with 167 supplements in our database — Piracetam is not one of them. The Lisinopril interaction page linked on this page lists every one, ranked by severity.
