Summary
Increasing ease of access of long-acting birth control methods, like intrauterine devices (IUDs), is an important way to reduce the risk of unintended pregnancy. Unfortunately, fear of IUD insertion in women who have not had children is common among health care providers and women alike, and this limits IUD use. To increase acceptance of this highly effective birth control method, there is a need to explore new, low cost, and easily applied methods to improve the insertion experience. This is a pilot study to evaluate the effectiveness and acceptability of nitroglycerin ointment applied vaginally to improve the IUD insertion experience for both patient and provider. The investigators hypothesis is that nitroglycerin ointment will decrease the pain associated with IUD insertion.
