Managing Allergies During Pregnancy Safely

When Allergies and Pregnancy Overlap

Sneezing, stuffy nose, itchy eyes — allergies are never fun. But when you are pregnant, managing them feels even harder. You want relief, but you also want to keep your baby safe. You may wonder which medicines are okay to take, which ones to avoid, and whether your allergies will get worse during pregnancy. You are not alone in asking these questions.

The good news is that many pregnant people find safe ways to manage their allergy symptoms. The key is knowing what options are available and talking to a licensed provider before starting any treatment. This article will walk you through what you need to know about allergies during pregnancy, including safe relief options and when to seek care.

How Pregnancy Can Change Your Allergies

Pregnancy causes big changes in your immune system and hormone levels. These changes can affect how your body responds to allergens like pollen, pet dander, dust, and mold. Some people find that their allergy symptoms get better during pregnancy. Others find that they get worse. Some people even develop allergies for the very first time while pregnant.

Nasal congestion is very common during pregnancy on its own. It is sometimes called “pregnancy rhinitis.” This condition is caused by increased blood flow and hormonal changes, not by allergens. It can be easy to confuse pregnancy rhinitis with allergy symptoms. A healthcare provider can help you tell the difference between the two so you can get the right kind of relief.

It is also important to know that if you have asthma along with your allergies, pregnancy requires extra care. Uncontrolled asthma during pregnancy can affect your oxygen levels and your baby’s growth. Working closely with your provider is especially important if asthma is part of your picture.

Allergy Medicines to Approach With Caution

Not all allergy medicines are considered safe during pregnancy. Some over-the-counter options that you used before pregnancy may need to be avoided or used only under a provider’s guidance. This is why it is so important to check before you take anything, even products labeled as “natural” or “herbal.”

Decongestants like pseudoephedrine are generally avoided during the first trimester and used with caution later in pregnancy. Some studies suggest these medicines may carry risks early in fetal development. Nasal decongestant sprays that cause rebound congestion can also become a problem if used for more than a few days.

Certain antihistamines have been used during pregnancy with a relatively good safety profile, but the research varies depending on which one you choose. First-generation antihistamines like diphenhydramine (Benadryl) have been used for many years in pregnancy, while some second-generation options are also considered acceptable. However, no medicine should be assumed completely risk-free. Always talk to your provider before taking any antihistamine during pregnancy.

Safer Strategies for Allergy Relief

The safest first step in managing allergies during pregnancy is to reduce your exposure to the things that trigger your symptoms. This is called allergen avoidance, and it does not carry any risks for you or your baby. While it may not eliminate your symptoms completely, it can make a real difference.

Here are some practical steps you can take:

• Keep windows closed on high pollen days and use air conditioning when possible.
• Shower and change clothes after spending time outdoors to wash off pollen.
• Use allergen-proof covers on pillows and mattresses if dust mites are a trigger.
• Vacuum regularly and consider a vacuum with a HEPA filter.
• Keep pets out of the bedroom if pet dander triggers your symptoms.
• Check daily pollen counts and limit time outside when counts are high.

Saline nasal rinses or saline sprays are another helpful, non-medicine option. They help flush out allergens from your nasal passages and can reduce congestion naturally. Many providers recommend them as a safe first-line option during pregnancy. Make sure to use distilled or sterile water if you are doing a nasal rinse at home.

Allergy Shots During Pregnancy

Allergy shots, also called allergen immunotherapy, are a long-term treatment that slowly makes your immune system less reactive to allergens. If you were already getting allergy shots before becoming pregnant, your provider may recommend continuing them at your current maintenance dose. Most guidelines suggest it is safe to continue allergy shots during pregnancy if you have already reached a stable dose.

However, starting allergy shots for the first time during pregnancy is generally not recommended. The reason is that the build-up phase carries a higher risk of allergic reactions. These reactions could be harmful during pregnancy. If you were not already on immunotherapy when you became pregnant, it is typically recommended to wait until after delivery to begin this type of treatment.

When to Talk to a Provider

It can be tempting to just push through your allergy symptoms or grab whatever is on the pharmacy shelf. But during pregnancy, getting professional guidance is especially important. A provider can review your specific situation, consider how far along you are in your pregnancy, and recommend the most appropriate treatment plan for you.

You should reach out to a provider if your allergy symptoms are severe enough to affect your sleep, your breathing, or your daily life. You should also get care if you are unsure whether your symptoms are from allergies, a cold, or pregnancy rhinitis. Getting the right diagnosis means getting the right treatment.
