Licorice should be used with caution in women taking birth controls pills or other hormonal medications. Licorice may change hormone levels in the body and decrease effectiveness of estrogen containing medications like conjugated estrogens (Premarin), ethinyl estradiol, and estradiol (Estrace).

Licorice should be used with caution with blood pressure medications because large amounts of licorice can increase blood pressure and decrease the effectiveness of blood pressure medications.

PREGNANCY: Licorice is not safe for pregnant women because it may cause miscarriage or early delivery; therefore, licorice should not be used in pregnant women.
