Objectives
By the end of this lecture, attendees should be able to:
• Know the effects of hormonal contraception on women with certain
common medical conditions
• Use the CDC Medical Eligibility Criteria and Selected Practice
Recommendations for Contraceptive Use in practice
• Refine counseling and prescribing practices for contraception when
medication interactions are likely
4
U.S. Medical Eligibility Criteria for Contraceptive Use, 2016
Safe use of contraceptive methods by women and men
with certain characteristics or medical conditions
Target audience: health care providers
Purpose: to assist health care providers when they
counsel patients about contraceptive use and to serve as a
source of clinical guidance
Content: more than 1800 recommendations for over 120
conditions and subconditions
10/16/2017

5
Why is evidence-based guidance for contraceptive use
needed?
To base family planning practices on the best available
evidence
To address misconceptions regarding who can safely use
contraception
To remove unnecessary medical barriers
To improve access and quality of care in family planning
6
CDC Medical Eligibility Criteria for Contraceptive Use:
Categories
U.S. Medical Eligibility Criteria for Contraceptive Use, 2016.
1No restriction for the use of the contraceptive method
for a woman with that condition
2Advantages of using the method generally outweigh
the theoretical or proven risks
3
Theoretical or proven risks of the method usually
outweigh the advantages – not usually recommended
unless more appropriate methods are not available or
acceptable
4Unacceptable health risk if the contraceptive method
is used by a woman with that condition

How safe is contraception?
Risk of death per year
From an automobile accident 1 in 5,000
From combined oral
contraception
Age 15-34 1 in 1,667,000
Age 35-44 1 in 33,000

Anna, a 43 year old G1P1001 healthy woman, comes in
requesting contraception. She has completed childbearing,
has always used condoms, but recently had an unintended
pregnancy and miscarriage. Her teenage daughter recently
started on the combined oral contraceptive pill and Anna is
now interested in starting the pill as well.

Effect of COC on blood pressure
COCs cause a mild increase in blood
pressure
• Systolic 7-8 mm Hg
•Diastolic 6 mm HG
Mechanism: Thought to involve the renin
angiotensin system
• Increase in plasma angiotensinogen, a renin
substrate
• Changes persist for 3-6 months after
stopping pills
