Magnesium and Drospirenone

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

Moderate

POTASSIUM-SPARING DIURETICS

Why this applies to Drospirenone

Drospirenone falls under POTASSIUM-SPARING DIURETICS — the group Magnesium interacts with.

Potassium-sparing diuretics decrease excretion of magnesium, possibly increasing magnesium levels.
Potassium-sparing diuretics also have magnesium-sparing properties, which can counteract the magnesium losses associated with loop and thiazide diuretics. Theoretically, increased magnesium levels could result from concomitant use of potassium-sparing diuretics and magnesium supplements.
Severity Moderate Likelihood Probable Evidence D

Interaction has not been documented in well-controlled studies, however, the interaction has been demonstrated in some small human studies or in controlled animal studies in conjunction with multiple case reports..

Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Here's the thing about drospirenone, the progestin found in certain birth control pills like Yaz and Yasmin. Unlike most progestins, it behaves a bit like a potassium-sparing diuretic, meaning it can nudge your potassium up slightly and, in theory, hold onto magnesium too. If you're also taking a magnesium supplement, the concern is that your magnesium level could creep a little higher than expected.

For most healthy people with good kidney function, this is largely theoretical and unlikely to cause trouble, since your kidneys clear out extra magnesium just fine. The bigger flag is potassium. If you have kidney issues or take other potassium-raising medicines, mention this combo to your pharmacist or doctor so they can keep an eye on your levels.

About Magnesium

What is Magnesium?

Magnesium
  • Preventing or treating magnesium deficiency
  • Constipation
  • Muscle cramps
  • Sleep support
  • Anxiety and stress
  • Migraine prevention

Magnesium is an essential mineral your body needs for muscles, nerves, blood pressure, and many other functions, and supplements are useful for preventing or correcting deficiency. Some other uses, like easing constipation or preventing migraines, have reasonable support, while uses for sleep and anxiety are less proven. It is generally safe for most healthy people at recommended amounts, but talk to your pharmacist or doctor before starting, especially if you have kidney problems.
