Risk of visual disturbance (like scotoma & photopsia); patients should be warned that visual symptoms may render activities such as driving a car or operating machinery more hazardous than usual, particularly under conditions of variable lighting; while etiology of visual symptoms is not yet understood, patients with any visual symptoms should discontinue treatment and have complete ophthalmological evaluation carried out promptly

Cases of hypertriglyceridemia reported; preexisting or family history of hyperlipidemia and use of higher than recommended dose and/or longer duration of treatment are associated with risk of hypertriglyceridemia; periodic monitoring of plasma triglycerides is recommended in patients with preexisting or family history of hyperlipidemia; pretreatment screening of triglyceride levels is recommended in patients initiating therapy

Use in pregnant women is contraindicated, as treatment does not offer benefit in this population; to avoid inadvertent administration during early pregnancy, appropriate tests should be utilized during each treatment cycle to determine whether ovulation and/or pregnancy occurs; patients should be evaluated carefully to exclude ovarian enlargement or ovarian cyst formation between each treatment cycle; the next course of therapy should be delayed until these conditions have been excluded

It is not known whether drug is excreted in human milk; because many drugs are excreted in human milk, caution should be exercised if drug is administered to a nursing woman; in some patients, therapy may reduce lactation
