Interactions with Dietary Supplements
Magnesium
A woman and her newborn infant experienced low blood levels of magnesium, which was possibly
due to chronic use of docusate throughout and after pregnancy.1 Controlled research
is necessary to determine whether people taking docusate for long periods of time need to
supplement magnesium.
Potassium
Taking docusate increases the amount of potassium excreted from the body in the
stool.2 Whether people taking docusate for long periods of time need to increase
their intake of potassium is unknown.
