Potassium chloride Pregnancy Warnings

Animal studies showed no adverse effects on embryofetal development. There are no controlled data in human pregnancy. It is considered unlikely that supplementation that does not lead to hyperkalemia would adversely affect the fetus.

AU Exempt: Medications exempted from pregnancy classification are not absolutely safe for use in pregnancy in all circumstances. Some exempted medicines, for example the complementary medicine, St John's Wort, may interact with other medicines and induce unexpected adverse effects in the mother and/or fetus.

US FDA pregnancy category Not Assigned: The US FDA has amended the pregnancy labeling rule for prescription drug products to require labeling that includes a summary of risk, a discussion of the data supporting that summary, and relevant information to help health care providers make prescribing decisions and counsel women about the use of drugs during pregnancy. Pregnancy categories A, B, C, D, and X are being phased out.

This drug should be used during pregnancy only if clearly needed. Use under physician supervision.

AU TGA pregnancy category: Exempt
US FDA pregnancy category: Not assigned

Comments:
-Pregnancy is associated with gastrointestinal hypomotility; solid forms of oral potassium should be given only if clearly needed.
-Close monitoring of serum potassium is recommended.
-Potassium supplementation that does not lead to hyperkalemia is not expected to cause fetal harm.
