Allergies

If you have allergies, pregnancy can make your symptoms worse. But you're right to worry about taking allergy medicine during pregnancy. Pregnant women shouldn't take some allergy drugs. Certain antihistamines, however, are safe. Check with your doctors -- your OB/GYN and your allergist -- to find out how to manage allergies while you're pregnant. Your doctor may tell you to avoid allergy meds until after your first trimester or suggest a change in treatment.

If you have been taking allergy shots for some time, you can likely continue them during pregnancy. But, don’t start allergy shots for the first time while pregnant.

Call Doctor If:

  • You are considering taking an allergy medication.
  • You have allergies and find out you are pregnant.
  • Your allergy symptoms bother you a lot.

Step-by-Step Care:

  • Try to avoid your allergy triggers.
  • Use saline nose spray to ease your congestion.
  • Keep animals out of your bedroom.
  • Vacuum often. Use filter vacuum bags or filtering vacuums.  
  • Use the air conditioner to keep humidity low and irritants out of the house. And keep your windows closed.
  • Shower and wash your hair after being outdoors if pollen sets off your allergies.
  • Avoid smoke, strong odors, and car exhaust. These commonly trigger allergy symptoms.
