Hypersensitivity to dutasteride, other 5α-reductase inhibitors, or any component of Avodart.
Use in pregnancy and children: Dutasteride is contraindicated for use by women and children. Dutasteride has not been studied in women because preclinical data suggests that the suppression of circulating levels of dihydrotestosterone may inhibit the development of the external genital organs in a male foetus carried by a woman exposed to dutasteride.
