The bottom line No known interaction

We found no known interaction between Skullcap and Fenofibrate 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.

Interaction report

Skullcap and Fenofibrate

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 Fenofibrate and Skullcap 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.

Skullcap safety at a glance

Skullcap overall Use caution Often used short-term, but evidence is limited and product quality varies, so use with care.

Pregnancy Avoid Not enough safety data, so it is best avoided during pregnancy.

Breastfeeding Avoid Safety is unknown, so avoid 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 Fenofibrate

Interactions in our licensed database are recorded against drug classes, not just single drug names. Fenofibrate is filed under 3 classifications — cytochrome p450 2c9 (cyp2c9) inhibitors, hepatotoxic drugs, oral drugs. Skullcap has documented interactions with 1 drug class — the most serious being cns depressants (moderate) — and none of Fenofibrate’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

Skullcap Does Interact With Other Medications

Skullcap has 248 moderate known drug interactions in our database — Fenofibrate isn’t one of them. If you take anything else, check it against the full list below.

What to actually watch for

What Skullcap Itself Has Been Linked To

This is not an interaction — nothing below involves Fenofibrate. It is the side-effect record for Skullcap on its own, from the licensed Natural Medicines monograph. If something new turns up after you add Skullcap, this list is the first place to look. One entry is worth acting on rather than waiting out — marked below.

Memory problems Worth acting on Additional detail
“A single skullcap extract dose of 100 mg does not seem to have adverse CNS effects. However, a higher dose of 200 mg might cause sedation and cognitive impairment. One patient taking skullcap 350 mg three times daily for 2 weeks reported vivid dreams. It is unclear if this event was associated with skullcap.”

Everything above comes from the Natural Medicines adverse-effect record for Skullcap — expand a row for the licensed statement it rests on. We read the ADVERSE REACTIONS section of Fenofibrate’s FDA label too, and the two lists don’t meaningfully overlap — which is why no Fenofibrate column appears here.

Overlapping uses

What Fenofibrate Is Prescribed For, and What Skullcap Has Been Studied For

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

Fenofibrate is prescribed for: Fenofibrate is used alongside a cholesterol-lowering diet in adults to improve abnormal lipid levels. Tricor (tablet) and fenofibrate tablets are indicated to lower LDL cholesterol (bad cholesterol), total cholesterol, triglycerides, and apolipoprotein B, and to raise HDL cholesterol (good cholesterol) in adults with primary hypercholesterolemia (high cholesterol) or mixed dyslipidemia (mixed abnormal lipid levels). They are also used to treat severe hypertriglyceridemia (very high triglycerides). Antara and Lipofen (capsules) are indicated to reduce triglyceride levels in adults with severe hypertriglyceridemia, and to lower LDL cholesterol in adults with primary hyperlipidemia when other recommended LDL-lowering therapies cannot be used.

Read the rest of what Fenofibrate is prescribed for

Fenofibrate has not been shown to reduce heart attacks or cardiovascular deaths in patients with type 2 diabetes.

Skullcap has been studied for:

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

Skullcap for hyperlipidemia

Although there has been interest in using oral skullcap for hyperlipidemia, there is insufficient reliable information about the clinical effects of skullcap for this purpose.
Atherosclerosis studied, not established Skullcap has been studied for this. Natural Medicines rates the evidence: Insufficient Reliable Evidence To Rate Read what the research shows

Skullcap for atherosclerosis

Although there has been interest in using oral skullcap for atherosclerosis, there is insufficient reliable information about the clinical effects of skullcap for this purpose.

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

From our pharmacist’s overview on the Fenofibrate page

“Fenofibrate (Tricor, Antara) is a cholesterol and triglyceride medicine that can strain the liver on its own, so this list of 59 supplements deserves genuine care rather than a shrug. Most of it, 38 ingredients, involves herbs that also stress the liver, ashwagandha among them, and stacking those effects is the risk that matters most h…”

About Skullcap

What is Skullcap?

Anxiety and stress
Trouble sleeping
Nervous tension
Muscle spasms
General relaxation

American skullcap is an herb traditionally used to calm anxiety and promote relaxation, but solid human evidence is very limited. It is generally considered relatively safe for short-term use in healthy adults, though it should be avoided in pregnancy and breastfeeding and used cautiously because of possible liver concerns and product mislabeling.

Scutellaria lateriflora · Lamiaceae · Above-ground parts (leaves, stems, and flowers) · Tea, capsules, tinctures, liquid extracts, dried herb

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

Skullcap: dosing

There is no official, standardized dose for American skullcap. The right amount can vary depending on the product and the form (tea, capsule, or tincture).The safest approach is to follow the directions on the product label and not take more than recommended.

Taking Skullcap and Fenofibrate Together: Common Questions

Is it safe to take Skullcap with Fenofibrate?

We do not list a known interaction between Skullcap and Fenofibrate. 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.

Are Skullcap and Fenofibrate 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 Skullcap in each. That is a conversation for your prescriber, especially if Fenofibrate is being adjusted to a target.

How was the Skullcap and Fenofibrate combination checked?

Interactions in our licensed database are recorded against drug classes. Fenofibrate is filed under 3 classifications, and Skullcap has documented interactions with 1 drug class — none of Fenofibrate'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 Skullcap interact with any other medications?

Yes. Skullcap has 248 documented drug interactions in our database — Fenofibrate 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 Fenofibrate interact with any supplements?

Yes. Fenofibrate has documented interactions with 59 supplements in our database — Skullcap is not one of them. The Fenofibrate interaction page linked on this page lists every one, ranked by severity.
