Precautions

Zecuity(R) was voluntarily withdrawn from the market by the manufacturer in June 2016 due to reports of serious application site reactions associated with use of this iontophoretic transdermal system. Since marketing of the patch in September 2015, there have been a number of reports in which patients describe severe redness, cracked skin, blistering or welts, and burns or scars where the patch was worn. Many report resolution within hours to weeks, although there are reports of unresolved skin reactions, typically skin discoloration.

Safety and efficacy have not been established in patients younger than 18 years.

Consult WARNINGS section for additional precautions.
