Mixing eplerenone with herbal remedies and supplements

St John's wort, a herbal medicine taken for depression, can affect how eplerenone works. Talk to your doctor if you're using it or planning to use it.

Do not take any potassium supplements, including salt substitute tablets. Taking these with eplerenone can cause your potassium levels to become too high. Some multivitamin and mineral supplements contain potassium. Always check the label.

There's not enough information to say that other complementary medicines, herbal remedies and supplements are safe to take with eplerenone. They're not tested in the same way as pharmacy and prescription medicines. They're generally not tested for the effect they have on other medicines.
