Pregnancy and its Effects on Asthma & Allergies

Pregnancy and its Effects on Asthma & Allergies

Pregnancy and its associated changes may affect either your asthma or rhinitis, or both. Should you become pregnant please notify your OAAC physician as soon as possible. This will allow us to work closely with the physician providing your obstetrical care. A team approach to the assessment and care of the pregnant allergic patient will result in the best care for your condition.

Remember, the final decisions on your medications and treatments are always made by the physician providing the obstetrical care. However, your OAAC physician should follow your asthma closely during the pregnancy. We can provide advice about continuation or discontinuation of treatments you are already on for your allergy/asthma prior to the pregnancy.

Allergy Immunotherapy (Shots)

There is no reason to discontinue immunotherapy during pregnancy. It does not pose a risk to the development of your baby. However, we do not want to present an increased risk for systemic reaction during the pregnancy.

Therefore all immunotherapy during a pregnancy must be at a stable or maintenance dose. We do not build or increase the dose of your shots during pregnancy. If you are on build-up of your immunotherapy and you become pregnant, contact your OAAC provider immediately to discuss how to proceed. If you are on your maintenance dose and are having symptoms from the injections or other concerns, contact your OAAC provider.

Rhinitis (Nasal Symptoms)

Your nasal allergy symptoms may improve (15%), worsen (34%) or stay unchanged (46%) during your pregnancy. Some patients develop unrelated non-allergic nasal congestion (rhinitis of pregnancy) during the second half of their pregnancy. If you are having problems please contact your OAAC physician. Some medications are considered safer than others during pregnancy. Non-medical approaches like saline nasal rinses and external nasal dilator strips are very safe.

Asthma

Asthma symptoms during pregnancy appear to worsen, improve or remain unchanged in roughly equal proportions (1/3, 1/3, 1/3). This means that some patients with even very mild asthma may develop more severe symptoms when pregnant. The period of greatest increased incidents of increased symptoms is the third trimester (2436 weeks).

Since the well-being of the baby depends on the severity of the asthma in the mother, close monitoring is necessary. We want to work with your obstetrical physician to maintain your asthma control with the least amount of medications possible. However, because uncontrolled asthma presents the greatest risk to the baby (versus drug side effects) it is imperative not to discontinue or change your asthma medications without the consultation of your OAAC physician. Inhaled steroids for example are considered safe and effective in pregnancy.

Asthma, Allergies and Pregnancy

 

If you are pregnant and have asthma or allergies, you may feel uneasy about taking medications, but it is very important to keep your symptoms under control.

How do you stay healthy and know which medications are best for you during your pregnancy?

An allergist / immunologist, often referred to as an allergist, can tell you which asthma and allergy medications are the safest and most effective to take throughout pregnancy. Make an appointment with an allergist soon after you discover you are pregnant to develop or review your personal treatment plan and to give you peace of mind.

In the meantime, here are answers to some common questions.

Can women with asthma have safe pregnancies?
Yes. With good asthma management, you can keep your asthma under control and have a healthy baby.

How does uncontrolled asthma affect the fetus?
Uncontrolled asthma symptoms can cause a decrease in the amount of oxygen in your blood supply. The fetus gets its oxygen from your blood. Since a fetus needs a constant supply of oxygen for normal growth and development, managing asthma symptoms is very important to allow you and your baby to get enough oxygen.

Is it safe to take my asthma medications?
The risks of asthma flare-ups are greater than the risks of taking necessary asthma medications. Studies show that most inhaled asthma medications are safe for women to use while pregnant. However, oral medications (pills) should be avoided unless necessary to control symptoms. Knowing which medications to take is a good reason to stay in close contact with your allergist so he or she can monitor your condition and alter your medications or dosages if needed.

Will being pregnant affect my asthma symptoms?
Pregnancy may affect the severity of your asthma symptoms. One study showed that asthma symptoms were worse in 35% of pregnant women, improved in 28% and remained the same in 33% of pregnant women. Asthma has a tendency to get worse in the late second and early third trimesters.

Can I continue to get allergy shots during pregnancy?
Allergy shots (a form of immunotherapy) are safe to take while you are pregnant. As always, your allergist will monitor your dose to reduce the risk of an allergic reaction to the shots. These reactions are rare; however, a reaction could be harmful to the fetus. Allergy shots are not started on patients who are pregnant but can be continued on patients who become pregnant while receiving it. Although current immunotherapy doses can be maintained during pregnancy, doses should not be increased until after delivery.

What should I avoid if I have asthma or allergies?
Whether you are pregnant or not, you should stay away from things that trigger your symptoms. This might include dust mites and animal dander, and irritants such as cigarette smoke.

Can women with asthma perform Lamaze?
Most women with asthma are able to do Lamaze breathing techniques without any problems. Asthma symptoms are rare during labor and delivery in women whose asthma has been managed during pregnancy.

Can I breastfeed if I am taking medications for my asthma or allergies?
Breastfeeding is a good way to increase your child's immunity, and it is strongly recommended. Medications recommended for use during pregnancy can be continued while nursing, because the baby gets less maternal medicine through breast milk than in the womb. Your allergist can discuss with you the best treatments while nursing.

Healthy Tips
Although these are common questions during pregnancy, each patient's individual treatment varies. It is best to visit your allergist regularly during pregnancy so that any worsening of asthma can be countered by appropriate changes in your asthma management plan. Make sure to discuss any specific concerns with your physician to ensure the healthiest pregnancy for your well being and that of your baby.

• You can have a healthy pregnancy if you have asthma or allergies.
• Managing your symptoms is very important during pregnancy.
• Do not stop taking your medications.
• An allergist has special training to develop or review a treatment plan that is right for you while you are pregnant.
