Would you use a patch of 100 tiny needles over the contraceptive pill?
A patch filled with tiny needles can inject up to 60 days’ worth of hormonal contraceptives. Women could apply the patch at home, making it a potentially hassle and pain-free alternative to injections or implants.
Mark Prausnitz at the Georgia Institute of Technology and his colleagues created the patch, which contains 100 microneedles, each around half a millimetre long and 0.01 millimetres wide at the tip. When the patch is applied, the needles come off the patch, break the skin and sit under the surface.
Each needle contains a small dose of the hormonal contraceptive levonorgestrel, which is slowly released as the microneedle degrades over a period of up to 60 days.
