Drug & supplement interaction

Lovage + Carbidopa

Carbidopa brand name: Lodosyn.

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 Lovage and Carbidopa 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.

Lovage and Carbidopa

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 Carbidopa and Lovage 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 Carbidopa

Interactions in our licensed database are recorded against drug classes, not just single drug names. Carbidopa is filed under 3 classifications — including oral drugs. Lovage has documented interactions with 1 drug class — the most serious being diuretic drugs (moderate) — and none of Carbidopa’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.

No Interaction Found — But Data Suggests Lovage and Carbidopa 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.

    Lovage

    “A high-quality assessment of the adverse effects of lovage has not been conducted. However, long-term oral use of lovage may result in an increased risk of phototoxic reactions, including photosensitivity (2,5,6,8,11,12). Topical exposure may also result in photosensitivity or contact dermatitis.”

Avoid excessive exposure to the sun or UV light if using lovage (2,12).

The skin healed after receiving topical and systemic steroids.”

    Carbidopa

    Listed in the ADVERSE REACTIONS section of the FDA label for Carbidopa. Read the label on DailyMed ›

Reported for Lovage but not commonly for Carbidopa: sun sensitivity.

Effects for Carbidopa come from the ADVERSE REACTIONS section of its FDA label; effects for Lovage come from the Natural Medicines adverse-effect record, quoted above. Where a percentage is shown, it is the share of 52,609 voluntary FDA FAERS reports for Carbidopa 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.

From our pharmacist’s overview on the Carbidopa page

“Carbidopa (Lodosyn) keeps levodopa working in Parkinson's disease, so anything that blocks its absorption can cost real motor control, and two of the 21 supplements on this list do exactly that at a level rated major. Magnesium is the one that surprises people: in a human study it cut carbidopa absorption by 81 percent and levodopa's b…”

About Lovage

What is Lovage?

  • Digestive upset and bloating
  • Mild urinary tract flushing
  • Water retention (mild diuretic)
  • Coughs and congestion
  • Menstrual discomfort
  • Culinary flavoring

Lovage is a celery-like herb traditionally used for digestion, bloating, and as a mild diuretic to flush the urinary tract. Human evidence for these uses is very limited, and while culinary amounts are generally well tolerated, concentrated supplements and the essential oil should be used cautiously. Pregnant and breastfeeding people should avoid it.

Levisticum officinale · Apiaceae · Root, leaves, seeds, and essential oil · Tea, capsules, tincture, dried root, essential oil, culinary herb

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

Lovage: dosing

There is no well-established or standardized dose of lovage for any health condition. Traditional preparations include teas made from the dried root or leaves, capsules, and tinctures, with amounts varying widely by product.The best approach is to follow the directions on the product label and not exceed the recommended amount. The essential oil is very concentrated and should not be taken by mouth without professional guidance.

About Carbidopa

What Is Carbidopa Used For?

Brand name: Lodosyn

Carbidopa tablets — sold under the brand name Lodosyn and as generic carbidopa — are used together with levodopa or carbidopa-levodopa to manage symptoms of Parkinson's disease, postencephalitic parkinsonism, and symptomatic parkinsonism that can result from carbon monoxide or manganese poisoning. Carbidopa is never used alone; it always works as a partner to levodopa-based therapy.

Lodosyn is specifically used when a patient taking carbidopa-levodopa isn't getting enough daily carbidopa from that combination, or when a patient needs the two drugs individually titrated (adjusted) rather than taken as a fixed combination. Adding carbidopa helps reduce the nausea and vomiting that levodopa often causes and allows lower doses of levodopa to be used.

Most-Reported Side Effects for Carbidopa

From FAERS, the FDA’s public side-effect reporting system (52,609 reports, all brands). Reports are voluntary and are not proof the drug caused the effect.

Fall 4,954 reports
Hallucination 4,554 reports

Taking Lovage and Carbidopa Together: Common Questions

Is it safe to take Lovage with Carbidopa?
We do not list a known interaction between Lovage and Carbidopa. 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 Lovage and Carbidopa 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.
How was the Lovage and Carbidopa combination checked?
Interactions in our licensed database are recorded against drug classes. Carbidopa is filed under 3 classifications, and Lovage has documented interactions with 1 drug class — none of Carbidopa'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 Lovage interact with any other medications?
Yes. Lovage has 75 documented drug interactions in our database — Carbidopa 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 Carbidopa interact with any supplements?
Yes. Carbidopa has documented interactions with 21 supplements in our database — Lovage is not one of them. The Carbidopa interaction page linked on this page lists every one, ranked by severity.
