Spring is beautiful — the flowers are blooming, the days are longer, and everything feels fresh and new. But if you’re pregnant and prone to seasonal allergies, this time of year can feel less like a postcard and more like a constant battle between you, your sinuses, and a pollen count that just won’t quit.
Here’s the good news: you don’t have to just white-knuckle it through allergy season. There are safe options, smart strategies, and a few things your body is doing differently right now that are worth knowing about. Let’s talk through all of it.
What Does Pregnancy Do to Your Allergies?
Pregnancy changes just about everything and your immune system is no exception. Here’s something that surprises a lot of people: about one-third of pregnant women find their allergy symptoms get worse during pregnancy, one-third see improvement, and one-third notice no change at all. So, if your allergies feel different this spring, you’re not imagining it.
A few reasons why this happens:
– Your immune system shifts during pregnancy to protect the baby, which can alter how your body responds to allergens like pollen, dust, and pet dander.
– Increased blood flow and higher estrogen levels can cause the mucous membranes in your nose to swell. That’s a condition called pregnancy rhinitis. It can make allergy symptoms feel amplified even without increased allergen exposure.
– Your sense of smell often becomes more sensitive during pregnancy, which can make environmental irritants feel more intense.
It’s also worth noting that pregnancy rhinitis (nasal congestion caused by hormones alone, not allergens) can look and feel a lot like allergies. If your symptoms started with pregnancy rather than spring, that might be what’s going on — and it’s worth mentioning to your provider.
Safe Allergy Medications During Pregnancy
This is the question we hear most and we want to give you a real answer!
Here’s a general overview of what is typically considered safe and what to approach with caution. Keep in mind that guidelines can vary and your individual health history matters, so always confirm with your provider at North Florida Women’s Care.
Generally Considered Safe (with provider approval):
– Loratadine (Claritin) — A non-drowsy antihistamine that is widely used and generally considered safe during pregnancy. It’s often the first recommendation.
– Cetirizine (Zyrtec) — Another second-generation antihistamine that is commonly recommended, particularly if Claritin isn’t providing enough relief.
– Diphenhydramine (Benadryl) — An older antihistamine that is generally considered safe in limited doses, though it causes drowsiness. It’s typically recommended more for short-term or nighttime use.
– Nasal corticosteroid sprays (like Flonase) — May use during pregnancy. Ask us about these.
– Saline nasal sprays and rinses — Completely safe, drug-free, and surprisingly effective. Rinsing the nasal passages with a saline solution can clear out allergens and reduce congestion without any medication at all.
– HEPA air purifiers and nasal filters — Not medication, but highly effective tools worth investing in during allergy season.
Use with Caution or Avoid:
Decongestants like pseudoephedrine (Sudafed) — Generally avoided, especially in the first trimester, as some studies have raised concerns about potential effects on fetal development.
Combination cold and allergy medications — These often contain decongestants or other ingredients that may not be safe during pregnancy. Read labels carefully and check with us first.
An important note:
“Generally safe” doesn’t mean take as much as you want. During pregnancy, the goal is always the lowest effective dose for the shortest time necessary. And what’s safe can vary based on your trimester, your health history, and any other medications you’re taking. When it doubt, ask us – that’s what we’re here for!
Non-Medication Ways to Feel Better
Sometimes the best medicine isn’t medicine at all. Here are some other ways to reduce your allergen exposure and keep symptoms manageable:
– Check the pollen count daily and limit time outdoors on high-pollen days, especially in the morning when counts are highest.
– Keep windows closed on high-pollen days and use air conditioning instead of letting fresh air in.
– Shower and change clothes after spending time outside to rinse pollen off your skin and hair.
– Use a saline nasal rinse (like a neti pot or NeilMed bottle) to physically flush allergens out of your nasal passages.
– Wear sunglasses outside to protect your eyes from pollen.
– Vacuum frequently with a HEPA filter vacuum and consider a HEPA air purifier in your bedroom.
– Keep pets that go outside out of the bedroom, as they can carry pollen in on their fur.
When to Call Your OBGYN (Us!)
We know it can feel like a lot to figure out what’s “worth” a phone call (or you could use your patient portal to send us a message). Here’s our honest answer: we’d rather hear from you. But to give you some guidance, here are the situations where you should reach out:
– Before starting any new allergy medication, even over-the-counter ones — just to confirm it’s safe for where you are in your pregnancy.
– If your nasal congestion is severe enough that you’re having trouble sleeping or breathing comfortably — this can affect your oxygen levels and deserves attention.
– If you develop wheezing, chest tightness, or shortness of breath — these can be signs of asthma triggered by allergens, which need prompt evaluation during pregnancy.
– If your symptoms include fever, colored mucus, or facial pain or pressure — these may indicate a sinus infection rather than allergies, and infections during pregnancy should be treated.
– Your comfort and your baby’s safety go hand in hand. You don’t have to suffer through spring just because you’re pregnant — but you also shouldn’t be navigating medication decisions alone. We’re here to answer your questions!
