An Evidence-based Approach to Contraception in Women with Medical Disease Jody Steinauer, MD, MAS University of CA, San Francisco

Objectives At the end of this talk you will be able to: At the end of this talk you will be able to: Easily access evidence-based recommendations for contraception in women with medical illness Understand the underlying evidence for these recommendations Balance the risks of contraception against the risks of pregnancy in these women

Outline Review WHO guidelines for contraception Review WHO guidelines for contraception Review evidence for specific medical situations and specific methods Review evidence for specific medical situations and specific methods Migraines Diabetes, HTN, CAD risk factors Postpartum Drug interactions Review contraindications by method Review contraindications by method Combined hormonal, progestin, IUC

Stroke The absolute risk of stroke in young women is low at <1 per 10,000 women-years. The absolute risk of stroke in young women is low at <1 per 10,000 women-years.

WHO: Headaches and CHC Initiate Continue Initiate Continue Non migranous (mild or severe)1 2 Migraine (i) without focal neurologic symptoms Age < Age > Age > (ii) with focal neurologic symptoms4 4 (at any age) (at any age) Prodrome = photo/phonophobia, N/V Focal symptoms = vision changes, numbness, parasthesias

AURA Focal neurological symptoms that occur just before or at the onset of the headache Not the same as premonitory or resolution symptoms: (hypo- or hyperactivity, depression, food cravings, yawning, fatigue, difficulty concentrating) Reversible symptoms that develop gradually over 5-20 minutes and last up to 60 minutes Most common - visual

Hormonal Contraception for Women with Migraines Considerations for CHCs Considerations for CHCs Lower & consistent estrogen levels with ring Consider 20 or 25 mcg pills Consider eliminating the placebo week in women who have migraines triggered by withdrawal of estrogen Regular follow-up in 1-3 months after initial Rx Stress need to discontinue method if HAs worsen Any Progestin-Only Method Any Progestin-Only Method

Conclusion WHO publishes excellent, evidence-based resource of recommendations for contraception in medically complicated women. WHO publishes excellent, evidence-based resource of recommendations for contraception in medically complicated women. Risks must be balanced with risks of pregnancy.
