MG and pregnancy

Before Getting Pregnant

  • If you have MG and want to become pregnant, talk with your MG doctor first.

    • They'll help make a safe plan for you and your baby.

    • This includes discussing medication which might not be safe for the fetus.

During Pregnancy

  • Most MG treatments stay the same when you're pregnant.

  • If patients had good control prior to pregnancy, their MG should remain stable during pregnancy.

  • But after giving birth, some moms might feel worse for a bit.

  • Common MG medicines are okay, but some should be changed for the baby's safety.

    • Oral pyridostigmine (Mestinon®) is the drug of choice in pregnancy

    • IV anticholinesterase inhibitors (like pyridostigmine) should not be used

    • Prednisone is the immunosuppressant drug of choice in pregnancy

  • Surgery (thymectomy) should be postponed until after pregnancy

Having Your Baby

  • Choose a hospital that knows about MG.

  • Your MG and baby doctors should talk to each other.

  • It's best to avoid home births.

  • Your baby might need special care right after birth.

Labor Time

  • Most MG moms have normal births.

  • Talking to an anesthesiologist before labor commences is advised.

  • Some medicines for high blood pressure during pregnancy (e.g., magnesium sulfate), aren't good for MG moms.

After Birth

  • Some babies born to MG moms might feel weak for a few days (transient neonatal MG)

    • This is temporary.

    • They might need short-term help with breathing and eating.

    • They'll feel better once the antibodies passed from the mother (through the placenta) prior to birth, are broken down
