Sinus problems during pregnancy — what's safe to take, what isn't
Pregnancy hormones make sinusitis worse for most women. Here is what is and isn't safe in each trimester.
Roughly one in five pregnant women develops or worsens sinus symptoms during pregnancy — rhinitis of pregnancy is a real thing. The combination of hormonal changes (increased blood flow to nasal mucosa) and immune adjustments means even women without prior sinus issues can suddenly feel like they have a perpetual cold.
The tricky part: most go-to sinus medications are not safe in pregnancy. Sudafed (pseudoephedrine) — avoid in first trimester. Most prescription decongestant sprays — avoid throughout. Antihistamines — some are safer than others; check with your obstetrician before any.
What's actually safe + effective:
• Saline nasal irrigation (Neti pot, saline sprays) — completely safe and surprisingly effective. Use distilled or boiled-cooled water. • Steam inhalation — safe and helps with congestion. • Sleeping with head slightly elevated — helps overnight drainage. • Paracetamol for headache — safe throughout pregnancy. • Plain antihistamines like cetirizine or loratadine — generally safe in second and third trimester; check with your OB.
When to escalate to ENT: high fever (over 38.5°C), facial pain not relieved by paracetamol, thick discoloured discharge for over 10 days, vision changes, or recurrent sinus infections. We may need to image (low-radiation sinus CT) and consider antibiotics safe in pregnancy.
For most women, sinus symptoms in pregnancy resolve within 1–2 weeks postpartum. The strategies above get you through.
