A report published recently in the Journal of Controlled Release describes a technique for administering contraceptive hormones through special backings on jewelry such as earrings, wristwatches, rings or necklaces. The contraceptive hormones are contained in patches applied to portions of the jewelry in contact with the skin, allowing the drugs to be absorbed into the body.

Initial testing suggests the contraceptive jewelry may deliver sufficient amounts of hormone to provide contraception, though no human testing has been done yet. A goal for the new technique is to improve user compliance with drug regimens that require regular dosages. Beyond contraceptives, the jewelry-based technique might also be used for delivering other drugs through the skin.

“The more contraceptive options that are available, the more likely it is that the needs of individual women can be met,” said Mark Prausnitz, a Regents Professor and the J. Erskine Love Jr. chair in the School of Chemical and Biomolecular Engineering at the Georgia Institute of Technology. “Because putting on jewelry may already be part of a woman’s daily routine, this technique may facilitate compliance with the drug regimen. This technique could more effectively empower some women to prevent unintended pregnancies.”

Contraceptive jewelry adapts transdermal patch technology that is already used to administer drugs that prevent motion sickness, support smoking cessation, and control the symptoms of menopause, but have never been incorporated into jewelry before. Contraceptive patches are also already available, but Prausnitz believes pairing them with jewelry may prove attractive to some women — and allow more discreet use of the drug delivery technology.
