Estrogen patch, described as smallest, available at pharmacies

NEW YORK — A patch for treating menopause that the manufacturer calls the smallest is now available.

Noven Pharmaceuticals announced the availability of Minivelle (estradiol) transdermal system in pharmacies. The patch, which the Food and Drug Administration approved in October 2012, is designed for treating hot flashes and night sweats in women with menopause.

The patch has a surface area nearly the same as a dime at its lowest strength of 0.0375 mg-per-day and is 34% smaller than Noven's Vivelle-Dot patch, the company said.
