Drug & supplement interaction

Jequirity + Methazolamide

Methazolamide brand name: Neptazane.

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 Jequirity and Methazolamide 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

Jequirity and Methazolamide

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 Methazolamide and Jequirity 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 Methazolamide

Interactions in our licensed database are recorded against drug classes, not just single drug names. Methazolamide is filed under 5 classifications — including carbonic anhydrase inhibitors, diuretic drugs, antihypertensive drugs. Jequirity has documented interactions with 3 drug classes — the most serious being anticoagulant/antiplatelet drugs (moderate), antidiabetes drugs (moderate) and cytochrome p450 3a4 (cyp3a4) substrates (minor) — and none of Methazolamide’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.

What to actually watch for

No Interaction Found — But Data Suggests Jequirity and Methazolamide 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. 3 of them are worth acting on rather than waiting out — marked below.

Reported for Jequirity but not commonly for Methazolamide: kidney problems, raised blood pressure, a fast or pounding heartbeat and sweating.

Effects for Methazolamide come from the ADVERSE REACTIONS section of its FDA label; effects for Jequirity come from the Natural Medicines adverse-effect record, quoted above. Where a percentage is shown, it is the share of 339 voluntary FDA FAERS reports for Methazolamide 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.

Everything else you take

See Every Supplement That Interacts With Methazolamide

This page covers Jequirity only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Methazolamide page lists 218 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Activated Charcoal (major), American Hellebore (major), American Mistletoe (major), Lithium (major) and Oleander (major).

By severity: 7 major · 187 moderate · 24 minor.

From our pharmacist’s overview on the Methazolamide page

“Methazolamide (Neptazane) treats glaucoma by lowering pressure inside the eye, and because it also has mild water-pill effects it can nudge blood pressure and potassium on its own. That is exactly where most of the 218 supplements on this page press, and the list earns real caution.”

About Jequirity

What is Jequirity?

Jequirity
  • Asthma and cough
  • Fever
  • Sore throat and bronchitis
  • Liver complaints (hepatitis)
  • Constipation
  • Traditional infectious-disease remedies

Jequirity (Abrus precatorius) is a tropical plant whose bright red, black-tipped seeds contain abrin, one of the most toxic plant proteins known. Despite a long history in traditional medicine, the seeds are dangerously poisonous and there is no reliable evidence that it is safe or effective. It should not be used as a supplement or medicine.

Abrus precatorius · Fabaceae · Seeds, roots, and leaves · Traditional preparations (rarely used today); seeds are sometimes used in jewelry and beadwork

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

Jequirity: dosing

There is no safe or established dose of jequirity for use as a supplement or medicine. Because the seeds contain a deadly toxin, no amount is considered safe to swallow.We do not recommend taking jequirity in any form.

About Methazolamide

What Is Methazolamide Used For?

Brand name: Neptazane

Methazolamide tablets are used to treat eye conditions where lowering intraocular pressure (pressure inside the eye) is expected to help. These include chronic open-angle glaucoma and secondary glaucoma.

Methazolamide tablets are also used before surgery in acute angle-closure glaucoma, when reducing eye pressure ahead of the procedure is needed. Note that long-term use in angle-closure glaucoma is not appropriate.

Most-Reported Side Effects for Methazolamide

From FAERS, the FDA’s public side-effect reporting system (339 reports, all brands). Reports are voluntary and are not proof the drug caused the effect.

Fatigue 41 reports
Dizziness 29 reports
Dyspnea 28 reports
Headache 28 reports

Taking Jequirity and Methazolamide Together: Common Questions

Is it safe to take Jequirity with Methazolamide?
We do not list a known interaction between Jequirity and Methazolamide. 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 Jequirity and Methazolamide have any of the same side effects?
Yes — our sources link each of them separately to 7 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 Jequirity and Methazolamide combination checked?
Interactions in our licensed database are recorded against drug classes. Methazolamide is filed under 5 classifications, and Jequirity has documented interactions with 3 drug classes — none of Methazolamide'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 Jequirity interact with any other medications?
Yes. Jequirity has 811 documented drug interactions in our database — Methazolamide 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 Methazolamide interact with any supplements?
Yes. Methazolamide has documented interactions with 218 supplements in our database — Jequirity is not one of them. The Methazolamide interaction page linked on this page lists every one, ranked by severity.
