Does magnesium affect sertraline?

Hi, Mary!
I tried running this through the Interactions Checker but there seem to be a couple dozen different magnesium formulations (magnesium citrate, magnesium sulfate, etc.) some of which can cause interactions and others not.
If you know what kind your magnesium is you can try the Checker:

Better yet... ask your pharmacist.
