When you're pregnant and your nose is constantly stuffed up, it’s hard to tell if it’s just pregnancy hormones or full-blown allergic rhinitis. That’s where nasal steroids, a type of intranasal corticosteroid spray used to reduce inflammation in the nasal passages. Also known as intranasal corticosteroids, they’re one of the most common treatments for chronic congestion, sneezing, and runny nose during pregnancy. But the big question isn’t just whether they work—it’s whether they’re safe for you and your baby.
Here’s what the data shows: intranasal corticosteroids, medications like fluticasone, budesonide, and mometasone delivered directly into the nose. Also known as nasal sprays for pregnancy, they are absorbed minimally into the bloodstream. Unlike oral steroids, they don’t flood your system. Studies tracking thousands of pregnant women using these sprays found no increase in birth defects, preterm birth, or low birth weight. The American College of Obstetricians and Gynecologists (ACOG) even lists them as a preferred option for managing allergic rhinitis during pregnancy. That’s not a small endorsement—it’s the gold standard.
But not all nasal sprays are created equal. fluticasone, a widely studied nasal steroid with strong safety data in pregnancy. Also known as Flonase, it is often the first choice because it’s been used longer and studied more than others. budesonide, another top option, found in Rhinocort. Also known as Rhinocort Aqua, it has the most extensive pregnancy safety record among all nasal steroids. On the flip side, be cautious with decongestant sprays like oxymetazoline—they’re not steroids, and using them for more than three days can make congestion worse. And never use oral steroids unless your doctor says it’s absolutely necessary.
What if you want to avoid meds altogether? Simple changes can help. Saline rinses, humidifiers, and keeping windows closed during high pollen seasons cut symptoms without touching a prescription. Allergy shots (immunotherapy) are also safe to continue if you were already on them before pregnancy—but starting them during pregnancy isn’t recommended. The goal isn’t to eliminate every sniffle; it’s to find the safest, most effective way to breathe easier without risking your baby’s health.
