Autumn Crocus + Pramlintide

Pramlintide brand name: Symlin.

No Known Interaction
Medically reviewed by · Updated July 2026 · Pair last verified Sep 20, 2026
The bottom line No known interaction

We found no known interaction between Autumn Crocus and Pramlintide 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.

Autumn Crocus and Pramlintide

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 Pramlintide and Autumn Crocus 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 Pramlintide

Interactions in our licensed database are recorded against drug classes, not just single drug names. Pramlintide is filed under a single classification — antidiabetes drugs. Autumn Crocus has documented interactions with 1 drug class — the most serious being colchicine (major) — and none of Pramlintide’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 Autumn Crocus and Pramlintide 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. 2 of them are worth acting on rather than waiting out — marked below.

See Every Supplement That Interacts With Pramlintide

This page covers Autumn Crocus only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Pramlintide page lists 239 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Siberian Cocklebur (major), Acai (moderate), African Wild Potato (moderate), Agaricus Mushroom (moderate) and Agmatine (moderate).

By severity: 1 major · 208 moderate · 30 minor.

From our pharmacist’s overview on the Pramlintide page

“The single entry rated major on the pramlintide (Symlin) list is Siberian cocklebur, which has caused severe hypoglycemia in humans, not just in lab studies. That matters more than usual here because pramlintide is injected at mealtimes alongside insulin, and a dangerous low is already the main hazard of that pairing.”

About Autumn Crocus

What is Autumn Crocus?

Autumn Crocus
  • Gout
  • Familial Mediterranean fever
  • Joint pain and inflammation
  • Rheumatoid arthritis (traditional use)

Autumn Crocus is a highly poisonous plant that contains colchicine, a compound that has real medical value but is dangerous in its raw form. You should never eat the plant or take homemade preparations from it. If you need colchicine for gout or familial Mediterranean fever, use the standardized, FDA-approved prescription product under a doctor's supervision.

Colchicum autumnale · Colchicaceae · Corm (bulb-like underground stem), seeds, and flowers · Rarely used as a raw plant or crude extract; the purified active compound (colchicine) is available only as an FDA-approved prescription medicine

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

Autumn Crocus: dosing

There is no safe established dose of the Autumn Crocus plant as a supplement, and it should not be taken in any homemade form. The colchicine content of the plant cannot be reliably measured, so even small amounts can cause serious harm.The only appropriate way to use colchicine is through an FDA-approved prescription product, which has a precise, controlled dose set by your healthcare provider.

About Pramlintide Injection

What Is Pramlintide Injection Used For?

Brand name: Symlin

SymlinPen (pramlintide) is used as an add-on treatment for adults with type 1 or type 2 diabetes who already use mealtime insulin but still haven't reached their target blood sugar levels — even with optimal insulin therapy.

It is not a replacement for insulin. It works alongside insulin, given right before major meals, to reduce the spike in blood sugar that happens after eating.

Do Autumn Crocus and Pramlintide 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.

How was the Autumn Crocus and Pramlintide combination checked?
Interactions in our licensed database are recorded against drug classes. Pramlintide is filed under 1 classification, and Autumn Crocus has documented interactions with 1 drug class — none of Pramlintide'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.
