PIL KB
Affandi B. Contraceptive Update . PIT XVII POGI , Balikpapan 28-30 July 2008
MEKANISME KERJA PIL KB
* Mencegah pematangan dan pelepasan
sel telur
* Mengentalkan lendir leher rahim, sehingga
menghalangi penetrasi sperma
* Membuat selaput lendir rahim tidak siap
untuk menerima dan menghidupi hasil
pembuahan

Simplified Classification of Eligibility Criteria
(WHO)
WHO guidelines classify conditions that
affect medical eligibility for various
contraceptive methods into 4 categories
1
A condition for which there is no restriction for the use of
the contraceptive method
2
A condition in which the advantages of using the method
generally outweigh the theoretical or proven risks
3
A condition in which the theoretical or proven risks usually
outweigh the advantages of using the method
4
A condition that represents an unacceptable health risk if
the contraceptive method is used
World Health Organization. Medical Eligibility Criteria for Contraceptive Use, 4th ed. 2010.
Unmet Need : Fertility Preferences of
Postpartum Women
• Key Findings in Indonesia (IDHS 2012)1 :
– 85% of currently married women and 53% of currently
married men who have 2 living children do not want to
have more children. The percentage wanting no more
children increases rapidly with the number of living
children.
• According to many DHS surveys2:
– 92-97% of women do not want another child within 2 years
after giving birth
– But 35% of women had their children spaced at 2 years
apart or less
– 40% of women who intend to use a FP method in the first
year postpartum are not using one

2. Ross JA and Winfrey WL, 2001
ACOG Recommendations
• LARC methods should be offered as first-line
contraceptive methods and encouraged as
options for most women
• LARC methods have few contraindications
• Almost all women are eligible for the implant
and IUDs

Counseling about hormonal contraceptive options is
an important part of the clinical consultation
“…even if the users appear knowledgeable about
their contraceptive method, there are likely
some areas where their knowledge could be
improved.”

•Postplacental (preferably
within 10 minutes after
expulsion of the placenta)
and immediate postpartum
insertion during the first
week after delivery (but
preferably within 48 hours)
are convenient effective and
safe times to insert copper
IUDs.

Practice Points
• When counselling men and women about
contraception, remember that there are many
different methods available
• Balanced messages, giving the advantages
and disadvantages of oral pill, lead to greater
user acceptability and continuation. Emphasis
should be placed on the safety, efficacy & non
contraceptive benefits of Yasmin.
Affandi B. Oral Contraceptive Pills & Weight Gain, FKUI/RSCM, April 2008
Good clinical decisions are founded
on 3 essential elements:
 Experience
 Perspective
 Evidence
 Providers bring experience, perspective and evidence from their education
and clinical practice in specific communities.
 Patients bring their own experience and perspectives, coloured by issues
such as geography, finance, culture and spirituality.
It is in this context and not in isolation, that available evidence
informs decisions.
