Drug & supplement interaction

Maca + Carbamazepine

Carbamazepine brand names: Tegretol, Tegretol XR, Equetro, Carbatrol, Carnexiv.

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 Maca and Carbamazepine 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.

Maca and Carbamazepine

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 Carbamazepine and Maca 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.

Worth understanding: our licensed dataset holds no drug-interaction record for Maca at all — not against Carbamazepine, and not against any other medication we track. This verdict therefore rests on the absence of any recorded data, not on research that looked at this combination and found nothing. We cannot rule an interaction out.

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.

Maca safety at a glance

Maca overall Use caution Generally well tolerated as a food, but supplement safety has not been studied long term.
Pregnancy Avoid Not enough safety data in supplement amounts, so avoid during pregnancy.
Breastfeeding Avoid There is not enough reliable information on safety while breastfeeding.

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

No Interaction Found — But Data Suggests Maca and Carbamazepine May Share a Side Effect

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.

Effects for Carbamazepine come from the ADVERSE REACTIONS section of its FDA label; effects for Maca come from the Natural Medicines adverse-effect record, quoted above. Where a percentage is shown, it is the share of 38,334 voluntary FDA FAERS reports for Carbamazepine 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 Carbamazepine Is Prescribed For, and What Maca Has Been Studied For

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

Carbamazepine is prescribed for: Carbamazepine is used to treat certain types of seizures — including partial seizures, generalized tonic-clonic (grand mal) seizures, and mixed seizure patterns. It works best for those specific seizure types; it does not appear to control absence (petit mal) seizures. It is also prescribed to relieve the intense facial pain of trigeminal neuralgia — a nerve condition that causes sudden, severe pain along the face. It is not a general painkiller and shouldn't be used for ordinary aches and pains.

Maca has been studied for:

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

    Maca for depression

    Although there has been interest in using oral maca for depression, there is insufficient reliable information about the clinical effects of maca 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 Carbamazepine on your own; if you are taking Maca 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 Carbamazepine page

“Carbamazepine (Tegretol, Carbatrol, Equetro) only controls seizures and mood episodes when its blood level stays inside a tight window, and 284 supplement and herbal ingredients on file can disturb that balance, 12 of them rated major. Grapefruit can push carbamazepine levels up, St.”

About Maca

What is Maca?

Maca
  • Low libido and sexual function
  • Energy and stamina
  • Menopause symptoms
  • Mood and stress
  • Fertility support

Maca is a nutrient-rich Andean root often used for energy, libido, and menopause symptoms. Early studies suggest it may modestly help sexual desire and some menopause symptoms, but the evidence is limited and not conclusive. It appears generally well tolerated in food amounts, but talk to your pharmacist or doctor before using it, especially if you are pregnant, breastfeeding, or have a hormone-related condition.

Lepidium meyenii · Brassicaceae · Root (hypocotyl) · Capsules, powder, tablets, liquid extracts, gelatinized powder

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

Maca: dosing

There is no official or standardized dose of maca, and the amounts used in studies have varied widely. Because of this, it is best to follow the directions on the product label.Maca is sold in different forms, including raw powder, gelatinized powder, capsules, and extracts, and the strength can differ between products. Do not assume that taking more will work better or be safer.

Taking Maca and Carbamazepine Together: Common Questions

Is it safe to take Maca with Carbamazepine?
We do not list a known interaction between Maca and Carbamazepine. 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 Maca and Carbamazepine have any of the same side effects?
Yes — our sources link each of them separately to one 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 Maca and Carbamazepine 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 Maca in each. That is a conversation for your prescriber, especially if Carbamazepine is being adjusted to a target.
Does Carbamazepine interact with any supplements?
Yes. Carbamazepine has documented interactions with 284 supplements in our database — Maca is not one of them. The Carbamazepine interaction page linked on this page lists every one, ranked by severity.
