The most common drug-related adverse event were decreased lilbido experienced by 13% of subjects receiving Avodart 2.5 mg/day followed by headaches, experienced by 8% of the Avodart 0.1mg/day group and 6% by both the Avodart 0.5mg/day and 2.5 mg/day group. There were no serious adverse events that were considered drug-related.

Partner Pregnancies

Five partner pregnancies were reported during the study. One female partner spontaneously aborted (study subject was on placebo) and one had a partial placenta previa with subsequent delivery of a normal male infant (study subject was on Avodart 0.5 mg). The other three pregnancies wee normal and resulted in the births of two males (two subjects on "Avodart 0.5mg and one on Avodart 2.5mg) and one female (subject on Avodart 2.5mg). None of the infants had genital or other abnormalities at birth (7).

Precaution

Avodart Soft Gelatin Capsules should not be handled by a woman who is pregnant or who may become pregnant because of the potential for absorption of dutasteride and the subsequent potential risk to a developing male fetus. Avodart is contraindicated for use in women. Avodart has not been studied in women because preclinical data suggest that the suppression of circulation levles of dihydrotestosterone may inhibit the development of the external genital organs in a male fetus carried by a woman exposed to dutasteride (6) REV 0704
