Multiple sclerosis (MS), a degenerative neurologic disorder, often begins in early adulthood. The illness itself does not complicate pregnancy or affect contraceptive choice.
Some MS patients take anticonvulsant medications, which may cause birth defects and interact with several hormonal birth control methods. Estrogen-containing methods and progestin-only pills are especially problematic for people treated with antiepileptic medications. (For details, see the Contraceptive Pearl on anticonvulsants).
Pregnancy and breastfeeding seem to lower the risk of MS flares. Pregnancy is associated with a decreased risk of demyelinating events. However, MS treatment options are limited during pregnancy and lactation. These factors complicate reproductive decisions for MS patients, making preconception and contraceptive counseling particularly important.
