Long-acting reversible contraceptives (LARCs)
- Long-Acting Reversible Contraceptives (LARCs) include hormonal and non-hormonal intrauterine devices (IUDs) and hormonal subdermal implants.
- The most commonly used and available IUD is a small T-shaped device inserted into the uterine cavity.
- There are two main types of IUDs: non-hormonal (copper) and hormonal.
- IUD insertion can be painful, especially in nulliparous patients. Pre-treatment with analgesics, and/or a paracervical block, may be offered.
- The hormonal subdermal implant is a small rod inserted under the skin of the arm, overlying the triceps muscle.
- The subdermal implant is typically inserted in the non-dominant arm, and is appealing to patients who are uncomfortable with vaginal exams, associated with IUD insertion.
