The bottom line No known interaction

We found no known interaction between Motherwort and Rh(D) Immune Globulin 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.

Interaction report

Motherwort and Rh(D) Immune Globulin

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 Rh(D) Immune Globulin and Motherwort 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.

What to actually watch for

No Interaction Found — But Data Suggests Motherwort and Rh(D) Immune Globulin 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.

About Motherwort

What is Motherwort?

Motherwort
  • Anxiety and stress
  • Heart palpitations
  • Menstrual discomfort
  • Menopausal symptoms
  • Insomnia

Motherwort is a traditional herb in the mint family long used for anxiety, heart palpitations, and women's reproductive complaints, but solid human evidence is very limited. It should be avoided during pregnancy and breastfeeding, and anyone with a heart condition or taking heart or blood-thinning medicines should talk to a doctor or pharmacist before using it.

Leonurus cardiaca · Lamiaceae · Aerial parts (leaves, stems, and flowering tops) · Tea, tincture, liquid extract, capsules, dried herb

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

Motherwort: dosing

There is no well-established standard dose for motherwort. Traditional preparations include teas made from the dried herb and liquid tinctures or extracts, and products vary widely in strength.Because doses are not standardized and product quality differs, the safest approach is to follow the directions on the specific product label and not exceed the suggested amount.

Taking Motherwort and Rh(D) Immune Globulin Together: Common Questions

Is it safe to take Motherwort with Rh(D) Immune Globulin?
We do not list a known interaction between Motherwort and Rh(D) Immune Globulin. 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 Motherwort and Rh(D) Immune Globulin have any of the same side effects?
Yes — our sources link each of them separately to 10 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.
Does Motherwort interact with any other medications?
Yes. Motherwort has 248 documented drug interactions in our database — Rh(D) Immune Globulin is simply not one of them. If you take anything else, it is worth checking each one; they are all listed on this page.
