No Known Interaction
The bottom line No known interaction

We found no known interaction between Jaborandi and Norgestrel 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.

Jaborandi 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 Jaborandi 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 Jaborandi 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.

What Jaborandi Itself Has Been Linked To

This is not an interaction — nothing below involves Norgestrel. It is the side-effect record for Jaborandi on its own, from the licensed Natural Medicines monograph. If something new turns up after you add Jaborandi, this list is the first place to look. 3 entries are worth acting on rather than waiting out — marked below.

We haven’t matched Norgestrel to its FDA label in our system yet, so we can’t compare its own side-effect list here — the leaflet that comes with your prescription is the authoritative list for Norgestrel.

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 Jaborandi

What is Jaborandi?

  • Dry mouth (xerostomia)
  • Glaucoma and high eye pressure
  • Promoting sweating
  • Increasing saliva production
  • Traditional remedy for various ailments

Jaborandi is a South American plant best known as the natural source of pilocarpine, a drug used in modern medicine for glaucoma and dry mouth. The raw herb is potent and potentially toxic, so it is not something to use casually as a home remedy. If you need its effects, use the FDA-approved pilocarpine products prescribed by your doctor rather than the crude plant.

Pilocarpus microphyllus · Rutaceae · Leaves · Standardized pharmaceutical extract (pilocarpine), eye drops, tablets, and historically as a tea or tincture

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

Jaborandi: dosing

There is no established safe dose for the crude Jaborandi herb, and we do not recommend self-dosing with the raw plant because its potency is unpredictable and it can be toxic.The purified drug pilocarpine is a different story — it comes in carefully measured tablets and eye drops with doses set by a doctor.

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
