Allergic rhinitis control in pregnancy

Overview

Allergic rhinitis is a condition where the inside of your nose becomes inflamed and irritated because of an allergy. It is often called hay fever. In pregnancy, many women find their symptoms change – they may get worse, stay the same, or even improve. The good news is that there are safe ways to manage it so you and your baby stay comfortable.

Yes, allergic rhinitis is very common, affecting around 1 in 5 people. It is also common in pregnancy, partly because hormones can affect your nasal passages.

It affects people of all ages, including pregnant women. If you already had hay fever before pregnancy, your symptoms might change. Some women develop it for the first time while pregnant.

Symptoms

Common symptoms

• Sneezing, especially after waking up
• Runny or stuffy nose
• Itchy nose, roof of the mouth, or throat
• Itchy, red, or watery eyes
• Coughing from postnasal drip (mucus dripping down the back of your throat)

Symptoms in children

• Children can have the same symptoms as adults, but they may also rub their nose a lot (called the allergic salute) or have dark circles under their eyes.
• They may have trouble sleeping, which can affect their mood and learning.

Symptoms in older adults

• Older adults may have less obvious symptoms, like a long-term stuffy nose or postnasal drip that causes a chronic cough.
• They might be more prone to sinus infections because of the congestion.

Causes

Main causes

• Allergic rhinitis happens when your immune system overreacts to harmless substances like pollen, dust mites, pet dander, or mould.
• During pregnancy, hormonal changes can make the inside of your nose more sensitive and swollen, which can worsen allergic reactions.

Risk factors

• Having a family history of allergies or asthma
• Having other allergic conditions like eczema or food allergies
• Living in areas with high pollen counts or indoor allergens

When to see a doctor

See a doctor urgently if:

• If your symptoms are severe and not responding to simple non-medication measures
• If you have difficulty breathing or signs of a sinus infection (fever, facial pain, coloured mucus)
• If you are concerned about any medicine you are using or considering

Book a routine appointment if:

• If you have hay fever that bothers you during the day or keeps you awake at night
• If you want to discuss safe treatment options during pregnancy
• If your symptoms started for the first time during pregnancy

Diagnosis

Your doctor will listen to your symptoms and ask about your history. They usually diagnose allergic rhinitis based on your symptoms, especially if they come at certain times of the year or after exposure to a trigger.

Tests that may be done

• You may not need any tests. If the diagnosis is unclear, your doctor might refer you for a skin prick test or a blood test to check for allergy antibodies. These tests are generally safe in pregnancy, but talk to your doctor first.

What to expect at your appointment

Your doctor will want to know your symptoms, your triggers, and what you have tried. They will also ask about your pregnancy and any other health conditions. The visit is meant to reassure you and find a plan that works for you and your baby.

Treatment

Treatment for allergic rhinitis during pregnancy focuses on safety for you and your baby. Many options are available, but the first choice is usually non-medication methods. If needed, your doctor can recommend medications that are considered low-risk during pregnancy. Never start or stop any medication without checking with your healthcare provider first.

Self-care at home

• Avoid your triggers as much as possible (for example, close windows when pollen counts are high, use dust-mite covers on your mattress and pillow, keep pets out of the bedroom).
• Use a saline nasal spray or rinse to keep your nasal passages moist and wash away allergens.
• Use a cool-mist humidifier in your bedroom to reduce dryness.
• Try a saline eye rinse if your eyes are itchy and watery.
• Get plenty of rest and drink enough water.

Medical treatments

If self-care is not enough, your doctor may suggest a type of antihistamine that is considered safe during pregnancy, or a nasal spray that contains a corticosteroid. These medications work by calming the allergic reaction and reducing inflammation. Your doctor will choose the one that has the best safety record in pregnancy. Some older antihistamines are also used. Do not use any over-the-counter allergy medicine without asking your doctor or pharmacist first.

When is surgery considered?

Surgery is not usually needed for allergic rhinitis, especially during pregnancy. It is only considered in very rare cases for severe problems like nasal polyps that block breathing, and it is usually postponed until after the baby is born.

Living with this condition

Living with allergic rhinitis in pregnancy means finding a routine that keeps your symptoms under control so you can focus on your health and your baby. Keep a diary of your symptoms and what makes them better or worse. Talk to your doctor if your plan stops working.

Lifestyle tips

• Check pollen forecasts and stay indoors when counts are high, especially in the early morning and evening.
• Shower and change your clothes after being outdoors to remove pollen.
• Use an air purifier with a HEPA filter in your bedroom.
• Wear sunglasses to protect your eyes from pollen.

Diet and exercise

A healthy, balanced diet rich in fruits and vegetables can support your immune system. Regular gentle exercise, such as walking or swimming, is fine as long as you avoid triggers – for example, exercise indoors on high-pollen days. Always stay hydrated.

Mental health and emotional wellbeing

Constant sneezing, congestion, and poor sleep can be frustrating and may affect your mood. It is normal to feel bothered by these symptoms. If you feel sad, anxious, or overwhelmed, talk to your midwife or doctor. They can connect you with support. If you have thoughts of harming yourself or your baby, please call your local emergency number or crisis line immediately.

Prevention

It is not always possible to prevent allergic rhinitis, especially if you have a family tendency. But you can reduce the impact by avoiding your known triggers as much as possible. Many women find that symptoms improve after pregnancy, but they might return in later seasons.

Complications

If left untreated

• Poor sleep quality, which can add to pregnancy fatigue
• Sinus infections (sinusitis) from blocked nasal passages
• Ear infections or hearing problems
• Worsening of asthma, if you have it

Long-term outlook

The outlook for allergic rhinitis in pregnancy is generally very good. Most women can find a safe and effective way to manage their symptoms. The condition does not harm your baby, and it often improves after you give birth. With the right support, you can stay comfortable throughout your pregnancy.
