LONG-ACTING REVERSIBLE
CONTRACEPTION
Long-acting reversible  contraceptives  (LARCs) provide effective   contraception
for an  extended    period  without requiring   user    action. Methods used
include intramuscular   injection   (e.g.   DMPA),  IUD (Mirena,    Paragard),  and
subdermal   contraceptive   implant (Nexplanon).
Advantages: considered  the most    effective   reversible  method  of
contraception   because patient compliance  is  not required;   "typical    use"    failure
rates   (<1%    per year)   are about   the same    as  "perfect    use"    failure rates   (similar
to  sterilization   procedures);    long-lasting,   convenient, well-liked  by  users,  and
very    cost-effective
Disadvantages:  higher  up-front    cost    ($800−900   in  United  States) as
compared    with    other   methods such    as  oral    contraceptive   pills,  the patch,  and
vaginal ring
