An Update: Myasthenia Gravis and Pregnancy.

Myasthenia gravis presents a risk factor for pregnancy and delivery, and can affect the newborn. In return, pregnancy can affect the course of myasthenia and worsen the disease during pregnancy requiring treatment modifications. Treatment optimization and drug safety should be addressed before conception. Delivery is complicated by prolonged labor. Newborns can develop neonatal myasthenia gravis, a treatable and transient disease. Patients should not be discouraged to become pregnant, but provided with supportive counseling, planning, and monitoring in a multidisciplinary team involving obstetrician, anesthesiologist, pediatrician, and neurologist. Pregnancy outcome is favorable in women who receive treatment and expert care.
