Of the 19 deaths attributed to a cardiovascular cause in the placebo arm, 12 occurred in the group of 1026 patients who did not switch to letrozole after study unblinding, and 7 occurred in the group of 1551 patients who switched to letrozole.

A total of 7 patients died from a stroke – 6 in the letrozole arm and 1 after switching from placebo to letrozole after study unblinding. Driving and operating machinery No studies on the effects of letrozole on the ability to drive and use machines have been performed.

However, since fatigue, dizziness, and uncommonly somnolence have been observed with the use of letrozole, caution is advised when driving or operating machinery while such symptoms persist.

In a smaller study (D2407) comparing 2 years of adjuvant treatment with letrozole or tamoxifen, significant differences were observed between treatments at all time-points in total cholesterol, LDL cholesterol and the HDL: LDL ratio in favour of tamoxifen.

Clinically relevant changes in total cholesterol at 2 years occurred significantly more often for patients treated with letrozole (17%) than with tamoxifen (5%). Monitoring of serum cholesterol is advised for patients treated with JAMP Letrozole Tablets.
