Eclampsia is treated by delivering the baby. If the baby is older than 28 weeks, a cesarean section is usually done. During a C-section, the baby is delivered through an incision made in the abdomen. Prolonging the pregnancy can harm the mother or cause the baby to die. Before a C-section is done, the mother's seizures and blood pressure may need to be controlled with medicines.
Magnesium sulfate is the medicine of choice to prevent and control seizures.
Diazepam may be used if the magnesium sulfate doesn't stop seizures. Medicines such as hydralazine and labetalol can be used to lower the blood pressure. A C-section may cause bleeding, infection, or even death. Medicines used to treat eclampsia may cause low blood pressure , breathing difficulties, nausea , or allergic reactions. After the baby is born, a woman may still have seizures for up to 6 weeks.
