Pregnancy changes everything. You expected the morning sickness and the weird cravings for pickles, but nobody really warns you about the "pregnancy rhinitis." Suddenly, your nose is a swollen, congested mess, and you can’t breathe well enough to sleep. It’s miserable. You’re staring at that bottle of Flonase or Afrin in your medicine cabinet, wondering if it's going to hurt the baby. Can you take nasal spray when pregnant? The short answer is usually yes, but "usually" is a heavy word when you’re growing a human being.
The truth is that your nasal passages are currently reacting to a massive surge in estrogen and progesterone. These hormones increase blood flow throughout your body—including the delicate membranes in your nose. They swell up. They produce more mucus. It’s not a cold, and it’s not exactly allergies, though pregnancy can make existing allergies feel like a nightmare.
The Safety Tier List: What Actually Works
When you’re looking at the shelf at CVS, you’ve got three main types of sprays. They aren't created equal.
First, you have saline sprays. These are basically just salt water. Brands like Ocean or Simply Saline are the "gold standard" for pregnancy because there is zero medication involved. They just wash out the gunk and provide a tiny bit of moisture. You can use these all day, every day. Honestly, if you haven't tried a high-volume saline rinse yet, start there. It’s annoying to do, but it’s the safest path.
Then there are the steroid sprays. We're talking about budesonide (Rhinocort), fluticasone (Flonase), and mometasone (Nasonex). For a long time, doctors were cautious, but the data has caught up. Budesonide is often the preferred choice because it has the most "Category B" data backing it up. This means animal studies didn't show a risk, and human studies are generally reassuring. These don't work instantly. You have to use them for a few days to see the swelling go down.

The Afrin Trap
Finally, we have decongestant sprays like oxymetazoline (Afrin). This is where things get tricky. Most OB-GYNs will tell you that a spray or two of Afrin is fine if you are so congested you can't breathe at night. But—and this is a big but—you cannot use it for more than three days. If you do, you hit "rebound congestion." Your nose becomes addicted to the spray. When it wears off, the swelling comes back even worse than before. During pregnancy, your mucus membranes are already sensitive, making you even more prone to this cycle.
What the Research Says About Risks
Let's get into the weeds. A major study published in Epidemiology looked at intranasal decongestants and birth defects. They analyzed data from the Slone Epidemiology Center Birth Defects Study. The researchers found some potential links between first-trimester use of certain decongestants and rare heart defects, but the absolute risk remains very, very low.
Most experts, including those at the American College of Obstetricians and Gynecologists (ACOG), suggest avoiding oral decongestants (like Sudafed pills) in the first trimester. The spray is different. Because you are spraying it into your nose, very little of the drug actually enters your bloodstream. It stays local. That’s why many doctors prefer a spray over a pill when you're expecting.
Real Talk: The "Pregnancy Rhinitis" Reality
I’ve talked to women who spent nine months unable to breathe through their noses. It affects your sleep. Lack of sleep increases stress. Stress isn't great for the baby either. So, the "safe" move isn't always "take nothing." The safe move is "take the minimum amount of the least invasive option to ensure you can function."

Some women find that external solutions help more than drugs.
- Breathe Right Strips: They look goofy, but they physically pull the nostrils open. Zero drugs.
- Elevation: Sleep with two pillows. Gravity is your friend.
- Humidity: A cool-mist humidifier can stop the "crusty" feeling that leads to inflammation.
Managing Chronic Allergies While Expecting
If your congestion is actually hay fever and not just pregnancy hormones, you might need something stronger than salt water. Cromolyn sodium (Nasalcrom) is an old-school mast cell stabilizer. It’s remarkably safe because it’s not a steroid or a stimulant. It prevents the allergic reaction from starting. The downside? You have to use it 3-4 times a day for it to stay effective.
If you are already on a prescription spray like Dymista or Azelastine, call your doctor. Azelastine is an antihistamine spray. While it's generally considered low-risk, some doctors prefer you switch to a corticosteroid like Rhinocort during the first trimester just to be extra cautious.
When to See a Specialist
Congestion isn't always just "the joys of pregnancy." If you have a fever, yellow or green mucus, or pain in your cheeks and forehead, you might have a sinus infection. Pregnancy makes you more susceptible to these because the fluid in your sinuses doesn't drain as well when things are swollen. If it's an infection, no amount of Flonase is going to fix the underlying bacteria. You might need pregnancy-safe antibiotics like Amoxicillin.

The Consensus on Flonase and Rhinocort
Most allergists and OB-GYNs now consider fluticasone (Flonase) and budesonide (Rhinocort) to be compatible with pregnancy. Budesonide actually has a Pregnancy Category B rating, which is the "best" rating a medicated spray can get.
One thing to watch out for: nosebleeds. Pregnancy already makes your nasal blood vessels fragile. Steroid sprays can dry out the lining of the nose, leading to those annoying "bloody tissues" every morning. If this happens, aim the spray toward the "outside" of your nose (toward your ear) rather than at the septum (the middle wall). This reduces irritation.
Practical Steps for Relief
You don't have to suffer in silence. If you are struggling to breathe, follow this hierarchy of intervention to keep things as safe as possible for your pregnancy.
- Start with the mechanical fixes. Use a Neti pot or a NeilMed squeeze bottle twice a day. Use distilled water only—never tap water.
- Add a physical barrier. Wear a nasal dilator strip at night to keep the airway open without medication.
- Use a Saline Gel. Products like Ayr can be applied to the inside of the nostrils with a Q-tip to prevent drying and cracking.
- Consult your OB-GYN about Budesonide. If the natural stuff fails, ask if you can start a daily steroid spray like Rhinocort.
- Keep Afrin as an absolute "emergency" only. Use it only for one night if you are truly unable to sleep, and never for more than two nights in a row.
The goal is to get you through to delivery. Once that baby arrives and your hormone levels crash, that "pregnancy nose" usually disappears within 48 hours. Until then, stay hydrated and keep your head elevated.
Actionable Next Steps
- Check your labels: Look for "Budesonide" as the active ingredient if you need a medicated spray, as it has the strongest safety profile in clinical literature.
- Hydrate aggressively: Drinking more water thins out the mucus, making it easier to drain without needing heavy medication.
- Audit your bedroom: Use a humidifier and wash your sheets in hot water to eliminate allergens that could be compounding your pregnancy rhinitis.
- Talk to your pharmacist: They can quickly identify which "store brand" versions of these sprays contain the specific active ingredients your doctor has cleared.
