Bugle and Progesterone (prescription drug)

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 Progesterone (prescription drug) and Bugle 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 Bugle at all — not against Progesterone (prescription drug), 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.

What Progesterone (prescription drug)’s Own FDA Label Lists

This is not an interaction — none of it involves Bugle. These are the most notable effects listed in the ADVERSE REACTIONS section of Progesterone (prescription drug)’s own FDA label, for the medication by itself. Knowing the drug’s own list makes it easier to work out the likely cause if something new turns up while you take both. 2 of them are worth acting on rather than waiting out — marked below.

  • Low mood Worth acting on

From the ADVERSE REACTIONS section of the FDA label for Progesterone (prescription drug).

From our pharmacist’s overview on the Progesterone (prescription drug) page

“Prescription progesterone (Prometrium, Endometrin) supports pregnancy, regulates cycles, and protects the uterine lining during estrogen therapy, and because a steady hormone level is the whole point of taking it, its 148 documented supplement interactions warrant genuine vigilance. Most of them act on CYP3A4, the liver enzyme that cle…”

Where does our data come from?
  • Source: the Natural Medicines (TRC Healthcare) clinical database — the evidence-graded professional reference for herb & supplement interactions. Bugle is not yet covered by that licensed database, so its write-up cites publicly available medical sources directly (see the references below).
  • Citation library: 103,510 references behind our interaction content, 65,311 of them resolved to verified PubMed/DOI sources. See every Bugle reference on this page ↓

  • What “no known interaction” means: no documented interaction in the sources above — not a guarantee of safety. Supplements are studied far less than prescription drugs, so we say exactly what the evidence supports, and nothing more.

About Bugle

What is Bugle?

  • Minor wounds and bruises
  • Sore throat and mouth irritation
  • Mild cough
  • Digestive complaints
  • Bleeding (traditional use)

Bugle (Ajuga reptans) is a traditional European herb once used to help wounds, bruises, and mouth or throat irritation. There is very little modern scientific research to confirm any of these uses, so its benefits remain unproven. If you want to try it, talk to a pharmacist or doctor first, and avoid it during pregnancy and breastfeeding because safety data are lacking.

Ajuga reptans · Lamiaceae · Aerial parts (leaves and flowering tops) · Dried herb, tea, tincture, topical preparations

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

Bugle: dosing

There is no established or standardized dose for bugle. Traditional use varied, and modern products are not common or well regulated.If you choose to use a bugle product, follow the directions on the label and do not exceed them.

About Progesterone Vaginal

What Is Progesterone Vaginal Used For?

Brand names: Prometrium, Endometrin, Utrogestan

Endometrin (vaginal insert) is used as part of an Assisted Reproductive Technology (ART) program to support embryo implantation and help maintain pregnancy through the first 10 weeks in infertile women under 35. It works by supplementing the body's natural progesterone when the corpus luteum (the structure in the ovary that normally produces progesterone) cannot do so on its own.

Crinone (vaginal gel) is used in ART programs to provide progesterone supplementation — or full progesterone replacement in women with partial or complete ovarian failure. Crinone is also used to treat secondary amenorrhea, which is when menstrual periods stop in women who previously had them.
