Objectives: EVRA® transdermal contraceptive patch was approved in
Austria in April 2003. Although extensive data has been obtained from large
clinical trials, information on satisfaction, compliance, adherence and
tolerance in a non-clinical trial population in Europe is limited. Objective of
this study was to evaluate satisfaction, compliance, patch adherence and
tolerability in women prescribed EVRA® over 3 consecutive, 4-week cycles.
Design and Methods: Open, non-interventional study in volunteer women
requiring hormonal contraception. An interim analysis of data from 1333 women
was performed using descriptive statistical methods.
Results: Between July and September 2003 more then 3000 women were
included from private gynaecological practices across Austria. The mean (+SD)
age was 27.2+7.6 years and the mean weight was 61.4+10.3 kg. 75.4%
of the women had previous experience with oral contraceptives. Only 8.9% had no
previous experience with contraceptive methods. 93% of women changed the patch
as instructed in the package insert during the first therapy cycle, and 95%
during the third cycle. Excellent skin adhesion was reported for 94.2% of the
patches during cycle 1 and 95.1% of the patches during cycle 3. 89.3% of women
rated contraception with EVRA® as highly convenient or convenient compared to
their previous contraceptive method. 86% of women and 92% of gynaecologists were
highly satisfied or satisfied with the usage of EVRA® by their patients. At the
time of interim analysis of 1333 users, no pregnancies were reported. EVRA® was
generally well tolerated ; no serious adverse events were reported . The most
common side effects during the first cycle were skin reactions at the
application site (7.0%), breakthrough bleeding or spotting (7.0%), breast
symptoms (3.3%), nausea and vomiting (3.2%) and headache (3.2%). After three
cycles, less side effects were reported with 4.9% of women reporting application-
site related skin reactions, 6.1% breakthrough bleeding or spotting, 3.1% breast
tension, 1.9% headache and 1.7% nausea and vomiting.
Conclusions: The use of EVRA®, a once – weekly contraceptive patch,
showed high compliance, satisfaction and good tolerability in Austrian women
treated in private practice. Adhesion of the contraceptive patch to the skin was
very good.
