Just weeks after receiving a close-out for a 2016 warning letter, adhesive patch maker Noven began recalling more than 130,000 boxes of its estradiol adhesive patches in two dose formulations.

Noven in May started a recall of two lots, or 70,870 boxes of its 0.0375 mg/day patches and two lots, consisting of 61,960 boxes of the 0.1 mg/day dose of Minivelle (estradiol transdermal system).

According to an FDA Enforcement report, the class II recall was initiated because the patches failed to meet specifications for their sheer adhesive properties.
