Allergy & pregnancy – what needs to be considered

A running nose, itchy eyes and a sore throat – allergy sufferers are not unfamiliar with these symptoms. Many allergy sufferers then resort to antihistamines or other antiallergic drugs or nasal sprays. However, this is often not possible during pregnancy. In general, allergy sufferers should pay attention to a few things during pregnancy .

What to do with allergies during pregnancy?

Even during pregnancy, women do not simply have to endure the symptoms of their allergy . There are various measures to deal with an allergy during pregnancy . There are various medications that can be used in consultation with the doctor. The first precautionary measure, however, is: Pregnant women should avoid the allergens they are familiar with as much as possible.

The windows should remain closed when pollen is flying. Dust and pollen catchers such as carpets and curtains should be removed from the home by the affected women during pregnancy. Since stress can increase the symptoms of the allergy, pregnant women should ensure that their daily routine is as stress-free as possible.

Only if it no longer works: medication & nasal sprays

If these simple tricks are not enough to relieve allergy symptoms, allergy can be treated with medications even during pregnancy. In most cases, treatment of allergic diseases with oral antihistamines is well tolerated by mother and child. However, it should only be taken after consultation with the doctor treating you.

Nasal sprays may only be used briefly and only after careful risk-benefit analysis. The soothing decongestant effect of the nasal sprays is based on a narrowing of the vessels. However, this is not only limited locally to the nose, but affects the entire body. The vessels of the placenta also contract.

Long-term use of decongestant nasal sprays and nose drops can result in a reduced supply of blood and nutrients to the unborn child. An alternative are nose drops that only contain a saline solution. Nasal rinses with saline solutions can also provide relief from hay fever .

Desensitization: continue or stop?

Hyposensitization must not be restarted during pregnancy. Otherwise, in rare cases, allergic shock reactions could occur that could endanger both mother and child. Women who started hyposensitization before birth and who tolerated it well can continue treatment during pregnancy. Here, however, the doctor or allergist treating you should carefully weigh up the risk-benefit ratio.

asthma during pregnancy

Many pregnant women with asthma are particularly concerned during pregnancy and wondering whether or not they can continue taking their medication. In one third of all pregnant women with asthma, the symptoms improve during pregnancy.

In one third of the pregnant women, the disease worsens, in the last third nothing changes. However, well-controlled asthma is not associated with an increased risk for the mother, the child and the course of the pregnancy. Uncontrolled asthma attacks, on the other hand, endanger the well-being of the child and the mother. Asthmatics should therefore, if possible, consult their doctor for a consultation before becoming pregnant.

What to do if you have an asthma attack?

Pregnant women with asthma preferably receive short-acting betamimetics for inhalation as on-demand or emergency medication. These cause the bronchi to expand quickly so that air can flow in and out more easily. The substance salbutamol in particular is used for this.

So far, no connections between the intake of bronchodilator agents and damage to the unborn child are known. In the case of very severe asthma attacks, administration of cortisone in tablet form may be necessary. Some studies show that this slightly increases the risk of a cleft lip and palate in children. However, the connection is not yet fully secured.

However, since not taking the required cortisone usually poses a greater risk to the well-being of the child, pregnant women should not do without the tablets if they are administered by the doctor.

Allergy inhibitors while breastfeeding?

During the breastfeeding period, the child absorbs the substances that the mother previously supplied through breast milk. As a result, the antiallergic drugs also get into the child’s blood. There are antiallergic drugs that can be taken while breastfeeding. However, women should avoid combined preparations if possible.

These often burden the baby unnecessarily. However, it should be noted that first-generation antihistamines in particular can cause extreme fatigue in both mother and child. However, newer antihistamines do not have this side effect.

This is how you prevent allergies in your child

In particular, children whose parents both suffer from atopic diseases have an increased risk of allergies. Allergy sufferers should therefore take preventive measures during pregnancy in order to enable their child to live as allergy-free a life as possible.

A major factor in the development of allergies and asthma in children is active and passive smoking during pregnancy, breastfeeding and, of course, after childbirth. Cigarette smoke should therefore be strictly avoided. However, a diet during pregnancy in which the mother avoids certain allergy triggers has not proven to be effective.

On the other hand, exclusive breastfeeding for at least four months and then the slow introduction of supplementary food has a positive effect on the development of allergies in children.
