Women who received Norplant(R) contraceptive implants from any of fift
een clinical settings in southeast Texas, U.S.A., were followed for on
e year to determine their reactions to the method. Of 1,385 who enroll
ed to receive Norplant implants, 1,253 had implants inserted. Side eff
ects were reported by 78% of those receiving implants and 70% describe
d changes in bleeding patterns. Spotting or irregular bleeding, weight
gain and headaches were the conditions reported most frequently. Nine
pregnancies were reported during the study period. Six of these, howe
ver, existed before the implants were inserted. At the one year annive
rsary, 143 of women receiving implants had had them removed. Those who
discontinued method use were less satisfied, reported more side effec
ts and were more likely to have planned to have another child, thus us
ing the method for spacing, or to have had a change in their marital s
tatus while they were using the contraceptive. Providers should counse
l patients to focus attention on plans for the future in selecting the
ir contraceptive method. In addition, we recommend, as does the produc
t's distributor, that providers confirm that patients are not pregnant
prior to inserting implants.
