Lovage and Methazolamide

Here is the interaction we found between these two, with the evidence behind it.

Moderate

DIURETIC DRUGS

Why this applies to Methazolamide

Methazolamide falls under DIURETIC DRUGS — the group Lovage interacts with.

Theoretically, lovage root might interfere with diuretic therapy due to its aquaretic effects.
Some diuretics include chlorothiazide (Diuril), chlorthalidone (Thalitone), furosemide (Lasix), hydrochlorothiazide (HCTZ, Hydrodiuril, Microzide), and others.
Severity Moderate Likelihood Possible Evidence D

Interaction has been documented in animal or in lab research, or the interaction has been documented in humans but is limited to case reports or conflicting clinical research exists.

Dr. Brian Staiger, PharmD, BCPS
Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Here's the thing to keep in mind with methazolamide. It lowers eye pressure for glaucoma, but it also has a mild water-pill (diuretic) side, so it makes you urinate more. Lovage works as what we call an aquaretic, meaning it too can nudge your body to put out more fluid. Stacking those two together could, in theory, leave you a little more dehydrated than expected, with effects like extra urination, dizziness, lightheadedness, or feeling washed out.

I want to be honest, though: this concern is theoretical, based on how these things work rather than real cases in people. Everyday culinary amounts of lovage in cooking are very unlikely to matter. If you're using concentrated lovage supplements or the essential oil, just run it by your pharmacist or doctor first.

This page covers Lovage 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.

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 Lovage

What is Lovage?

  • Digestive upset and bloating
  • Mild urinary tract flushing
  • Water retention (mild diuretic)
  • Coughs and congestion
  • Menstrual discomfort
  • Culinary flavoring

Lovage is a celery-like herb traditionally used for digestion, bloating, and as a mild diuretic to flush the urinary tract. Human evidence for these uses is very limited, and while culinary amounts are generally well tolerated, concentrated supplements and the essential oil should be used cautiously. Pregnant and breastfeeding people should avoid it.

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.
