Allergy medicine when pregnant: what you need to know

Understanding allergies during pregnancy

Allergies occur when the immune system overreacts to a substance that is normally harmless, such as pollen, dust, or certain foods. During pregnancy, hormonal changes can affect the immune system, leading to changes in allergy symptoms. Some women may experience relief from allergies during pregnancy, while others may find their symptoms worsen.

Safe allergy management strategies

When it comes to managing allergies during pregnancy, it’s essential to prioritize safety for both the mother and the baby. Here are some strategies that pregnant women can consider:

Avoid triggers

One of the most effective ways to manage allergies during pregnancy is to avoid known triggers. Whether it’s pollen, pet dander, or certain foods, minimizing exposure to allergens can help reduce symptoms.

Use nasal saline sprays

Nasal saline sprays are a safe and effective way to alleviate nasal congestion and discomfort caused by allergies. These sprays work by moisturizing the nasal passages and flushing out allergens.

Try natural remedies

Many pregnant women turn to natural remedies to manage their allergy symptoms. Options such as honey, steam inhalation, and saline nasal rinses may provide some relief without the potential risks associated with medication.

Medication considerations

While some allergy medications are considered safe during pregnancy, others may pose risks to the developing fetus. It’s essential to consult with a healthcare provider before taking any medication during pregnancy. Here are some medications commonly used to treat allergies and their potential risks:


Antihistamines are commonly used to relieve allergy symptoms such as sneezing, itching, and runny nose. While certain antihistamines, such as loratadine and cetirizine, are generally considered safe during pregnancy, others, such as diphenhydramine, may have potential risks and should be used with caution.


Decongestants are often used to relieve nasal congestion caused by allergies. However, decongestants containing pseudoephedrine should be avoided during the first trimester of pregnancy due to the risk of birth defects. Phenylephrine, found in some over-the-counter decongestants, may be safer but should still be used with caution.

Nasal corticosteroids

Nasal corticosteroids are considered safe for use during pregnancy and are commonly prescribed to treat nasal congestion and inflammation associated with allergies. These medications work by reducing swelling in the nasal passages, making it easier to breathe.
Managing allergies during pregnancy requires careful consideration of the potential risks and benefits of various treatment options. While some medications may be safe for use during pregnancy, others should be avoided or used with caution. Pregnant women should work closely with their healthcare provider to develop a treatment plan that prioritizes the health and well-being of both the mother and the baby. By taking proactive steps to avoid triggers and exploring safe treatment options, pregnant women can effectively manage their allergies and enjoy a healthy pregnancy.
