Pregnancy: Clomifene use is contraindicated during pregnancy. Prior to administration of each cycle of Clomifene treatment, pregnancy should be ruled out.
Lactation: Lactation studies with Clomifene have not been conducted in humans, and it is not known whether it is excreted into human milk. Clomifene may reduce lactation in some nursing women. Caution should be exercised when administering Clomifene to a nursing woman.
