Manna and Hydrochlorothiazide, Triamterene

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

Moderate

DIURETIC DRUGS

Why this applies to Hydrochlorothiazide, Triamterene

Hydrochlorothiazide, Triamterene falls under DIURETIC DRUGS — the group Manna interacts with.

Theoretically, manna might increase the risk of hypokalemia when taken with diuretic drugs.
Manna contains mannitol, which acts as an osmotic laxative. Overuse of manna might compound diuretic-induced potassium loss, increasing the risk of hypokalemia.
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 something worth keeping in mind with this combo. Your medication actually pairs two water pills: hydrochlorothiazide can lower your potassium, while triamterene is potassium-sparing and works to hold potassium in. Because of that built-in balance, the two are designed to keep your potassium fairly steady.

Now, manna works as a mild osmotic laxative thanks to its mannitol. The concern here is mostly theoretical, but if you used a lot of manna and had frequent, watery stools, you could lose extra fluids and minerals, including potassium. Combined with the diuretic side of your pill, that could nudge potassium too low, leaving you tired, crampy, or with an irregular heartbeat. Occasional, modest use is unlikely to cause trouble, but check with your pharmacist or doctor before using manna regularly.

From our pharmacist’s overview on the Hydrochlorothiazide, Triamterene page

“Hydrochlorothiazide with triamterene (Dyazide, Maxzide) does two delicate jobs at once, pulling fluid off the body while holding on to potassium, and that is exactly where most of these supplements press. The great majority either add to its blood-pressure-lowering and diuretic effects, tipping people toward dizziness and unbalanced po…”

About Manna

What is Manna?

Manna
  • Gentle constipation relief
  • Mild laxative for children and elderly
  • Natural sweetener
  • Occasional bowel softening

Manna is the dried, sweet sap of the flowering ash tree (Fraxinus ornus) and is best known as a gentle, mild laxative because it contains a sugar alcohol called mannitol. It is generally considered mild and is sometimes used for occasional constipation, but high-quality modern studies are limited, so talk with your pharmacist or doctor before using it.
