Drug & supplement interaction

K2/spice + Amlodipine

Amlodipine brand name: Norliqva.

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 K2/spice and Amlodipine 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

K2/spice and Amlodipine

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 Amlodipine and K2/spice 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.

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

How we checked

Why No Interaction Is Listed for Amlodipine

Interactions in our licensed database are recorded against drug classes, not just single drug names. Amlodipine is filed under 5 classifications — including calcium channel blockers, antihypertensive drugs, cytochrome p450 3a4 (cyp3a4) substrates. K2/spice has documented interactions with 2 drug classes — the most serious being anticonvulsants (moderate) and qt interval-prolonging drugs (moderate) — and none of Amlodipine’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

No Interaction Found — But Data Suggests K2/spice and Amlodipine 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. 9 of them are worth acting on rather than waiting out — marked below.

About K2/spice

What is K2/spice?

  • Recreational drug ('legal high')
  • Marijuana substitute
  • Mood or perception changes
  • Sometimes used to avoid drug testing

K2/Spice is NOT a herbal supplement — it is plant material sprayed with man-made synthetic cannabinoid chemicals. It is dangerous, unpredictable, and has caused seizures, heart problems, psychosis, and deaths, so it should not be used.

Not a plant part; synthetic chemicals sprayed onto dried plant material · Dried plant material that is smoked or vaped; sometimes sold as liquid for vaping

An interaction check asks whether these two react with each other — it does not ask whether K2/spice is a good idea for someone in your situation. Here is what our K2/spice record says about it on its own.

K2/spice: dosing

There is no safe or recommended dose of K2/Spice. Because these are unregulated, illegal products with unknown and constantly changing ingredients, no dose can be considered safe. The strength can vary wildly even within a single package.This is not a supplement that should be taken at any amount. If you are looking for help with substance use, please reach out to a healthcare provider, pharmacist, or a substance-use support service.

About Amlodipine

What Is Amlodipine Used For?

Brand name: Norliqva

Amlodipine treats high blood pressure (hypertension) in adults and children aged 6–17 years. Lowering blood pressure reduces the risk of strokes and heart attacks. Sdamlo (oral solution) is specifically indicated for hypertension in adults and pediatric patients 6 years of age and older.

Amlodipine also treats coronary artery disease in adults, including chronic stable angina (chest pain with exertion), vasospastic angina (Prinzmetal's or variant angina, caused by coronary artery spasms), and documented coronary artery disease in patients without heart failure or significantly reduced heart pumping function.

Taking K2/spice and Amlodipine Together: Common Questions

Is it safe to take K2/spice with Amlodipine?
We do not list a known interaction between K2/spice and Amlodipine. 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 K2/spice and Amlodipine 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.
How was the K2/spice and Amlodipine combination checked?
Interactions in our licensed database are recorded against drug classes. Amlodipine is filed under 5 classifications, and K2/spice has documented interactions with 2 drug classes — none of Amlodipine'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 K2/spice interact with any other medications?
Yes. K2/spice has 208 documented drug interactions in our database — Amlodipine 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 Amlodipine interact with any supplements?
Yes. Amlodipine has documented interactions with 232 supplements in our database — K2/spice is not one of them. The Amlodipine interaction page linked on this page lists every one, ranked by severity.
