Information |

Take as directed; do not discontinue without consulting prescriber. Diabetics
should monitor serum glucose closely and notify prescriber of changes; this
medication can alter hypoglycemic requirements. You may experience acne, growth
of body hair, loss of libido, impotence, or menstrual irregularity (usually
reversible); nausea or vomiting (small frequent meals, frequent mouth care,
sucking lozenges, or chewing gum may help). Report changes in menstrual pattern;
deepening of voice or unusual growth of body hair; fluid retention (swelling of
ankles, feet, or hands, difficulty breathing, or sudden weight gain); change in
color of urine or stool; yellowing of eyes or skin; unusual bruising or
bleeding; or other adverse reactions. Pregnancy/breast-feeding
precautions: Inform prescriber if you are pregnant. Do not get pregnant
during or for 1 month following therapy. Consult prescriber for instruction on
appropriate contraceptive measures. This drug may cause severe fetal defects. Do
not breast-feed. |
