Seasonal allergies can be exacerbated during pregnancy. It’s not always the seasonal allergens that cause your body to react, as pregnancy hormones can also be the cause of unexpected, atypical, or more severe histamine production. Pregnancy is already stressful and physically challenging at times: worrying about what you can and cannot eat, consume or drink, and which activities should be avoided. But as far as allergies are concerned, there are plenty of antihistamine remedies available during a healthy pregnancy.

Seasonal Allergies & Your Baby

Even if you never experienced any seasonal allergy symptoms prior to your pregnancy, but are allergically reacting to something, rest assured your baby will not be the slightest bit uncomfortable—despite what you may be experiencing. More importantly, your reactions don’t indicate that your child will be born with allergies.

Different Seasonal Allergies & Pregnancy

There are two types of seasonal allergies during pregnancy: typical spring allergens that begin as early as February, and summer allergies that last until late fall. Pollen is the culprit for seasonal symptomatic reactions. Ragweed, grass, mold, tree pollen, and other regional pollen-producers can thankfully be avoided and there are healthy ways to soothe your symptoms.

Other pregnancy-related reactions are not caused by your environment: a condition called “Rhinitis of Pregnancy,” usually experienced during the third trimester, is caused by hormone level changes that mimic reactions to seasonal pollens. If you experienced season allergies prior to pregnancy, they may potentially worsen while pregnant. Fortunately, there are many safe ways to treat the reactions.

Treating Seasonal Allergies in Pregnancy

First, stay informed by checking your local pollen forecasts on weather and news apps. You may know some pollens to avoid, but your body can react to new irritants. Wear protective masks while doing outdoor activities like gardening or mowing, and make sure to shower and change clothes once inside. Stay indoors when pollen counts are highest, usually between 5am and 10am.

If you’re experiencing symptoms, saline nasal spray is a safe, effective treatment. It’s important to not use them more than three days in a row, as overuse can worsen nasal congestion. Wearing nasal strips at night opens breathing pathways and leads to a better night’s rest.

Avoidance is always the best form of treatment, but there are over the counter safe medications:

• Benadryl (diphenhydramine) is most recommended
• Zyrtec (cetirizine)
• Claritin (Loratadine)
• ChlorTrimeton (Chlorpheniramine)

Allergy shots, if begun prior to pregnancy, are usually safe to continue. It’s best not to start any allergy treatment during your pregnancy if you aren’t sure how your body will react. As always, should you experience abnormal symptoms of allergies—or severe reactions to allergy medications—while pregnant, reach out to your doctor.
