Buck's-horn Plantain and Norgestrel

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 Norgestrel and Buck's-horn Plantain 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 Buck's-horn Plantain at all — not against Norgestrel, 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.

From our pharmacist’s overview on the Norgestrel page

“Norgestrel (Ovrette) is a progestin-only birth control pill, so the biggest danger on this page is not a strange side effect but a pill that quietly stops working. That risk makes this a page for genuine vigilance.”

About Buck's-horn Plantain

What is Buck's-horn Plantain?

  • Eaten as a leafy salad green
  • Digestive complaints
  • Soothing irritated skin (topical, traditional)
  • Mild diuretic (traditional)
  • General tonic in folk medicine

Buck's-horn plantain (Plantago coronopus) is mainly a edible coastal salad green that has also been used in folk medicine for digestion and minor skin or urinary complaints. There is very little human research to support any medicinal use, so it should be viewed as a nutritious food rather than a proven remedy. If you want to use it for a health condition, talk with a pharmacist or doctor first.

Plantago coronopus · Plantaginaceae · Leaves (and sometimes seeds) · Fresh leaves (as a salad green or potherb), dried herb, tea/infusion, occasionally poultices

About Progestin-Only (norethindrone) Oral Contraceptives

What Is Progestin-Only (norethindrone) Oral Contraceptives Used For?

Brand names: Ovrette, Orval 21

Norethindrone progestin-only pills — sometimes called the "mini-pill" — are used solely to prevent pregnancy. They do not contain estrogen, which makes them an option for women who cannot or prefer not to use estrogen-containing contraceptives.

When taken perfectly (same time every day, no missed pills), fewer than 1 in 100 women will become pregnant in the first year. With typical use, that number rises to about 9 in 100 — mostly because of late or skipped pills. Consistency is everything with this method.

Most-Reported Side Effects for Norgestrel

From FAERS, the FDA’s public side-effect reporting system (2,254 reports, all brands). Reports are voluntary and are not proof the drug caused the effect.

Heavy menstrual bleeding 247 reports
Pregnancy on oral contraceptive 210 reports
Intermenstrual bleeding 182 reports
Polymenorrhoea 157 reports
Nausea 143 reports
