Is It Safe To Take An Antihistamine During Pregnancy
Antihistamines halt allergic reactions by preventing the action of histamines. Histamines are released by the immune system in response to what it interprets as attacking organisms. They cause cells to expand and leak fluid, and also cause capillaries to dilate. Antihistamines prevent histamines from binding with cells and causing these reactions, though histamines will still be produced.
There are both over-the-counter and prescription antihistamines available. It is safe to take both kinds of antihistamine during pregnancy as long as a health care provider has been consulted. Other allergy products may not be safe to take. Patients with high blood pressure during pregnancy may not be able to use antihistamines.
Even patients who do not usually take antihistamines might find the need to take an antihistamine during pregnancy. Some women report a worsening of allergy symptoms while pregnant. Many women experience nasal congestion during pregnancy, which can make allergies seem worse. It is not uncommon for women to develop new allergies while pregnant.
Can Pregnancy Make Me More Sensitive To Hay Fever
Yes during pregnancy you may find that you are more sensitive to your allergy triggers and that they are more troublesome. While the exact reasons for this are not clear, it may be due to hormonal changes that occur during pregnancy, and because during pregnancy your blood volume increases to support your growing baby.
If you do not have a history of allergy or hay fever and suddenly find you have symptoms, see your doctor to check for other conditions that may need to be treated.
Hay fever should not lead to serious breathing difficulties. If you feel you cant get enough air, your chest feels very tight, you are breathless, or you feel like youre being suffocated, seek medical advice immediately.
If you have unexplained breathing problems, especially if they are severe and come on quickly, call triple zero for an ambulance.
Avoid Certain Allergy Medicine While Pregnant
There are a number of medications that are not safe to take during pregnancy. First among them are oral decongestants.
Oral decongestants are best avoided altogether during the first trimester because of an uncertain risk of several rare birth defects, says Ciara Staunton, a family nurse practitioner and owner of Staunton Primary Care in Cincinnati. However, Sudafed , which is locked up behind the pharmacy counter, can be used in the second and third trimesters in women without hypertension.
But Staunton warns that Sudafed-PE , the over-the-counter option, should never be taken during pregnancy. It is less effective than pseudoephedrine. But more importantly, its safety for pregnant women is questionable.
Ms. Staunton also recommends against using any herbal therapies during pregnancy. In the United States and most other countries, herbal medicines are minimally regulated and not monitored for adverse events.

Diagnosis Of Allergy During Pregnancy
The diagnosis of allergy in pregnant women should focus on a detailed medical history and symptom analysis. For diagnosis, a diary of allergy symptoms and avoidance of suspected allergens accompanied by monitoring of changes of allergic symptoms may be helpful. It has to be emphasized that it is important not to put the mother on a rigid elimination diet for diagnosis of food allergy, as this could negatively influence the nutritional status of both the mother and the growing infant.
In vitro diagnostic tools such as serologic tests for allergen-specific IgE, e.g. ImmunoCAP or radioallergosorbent test , or the lymphocyte transformation test for type IV allergy diagnosis are preferred to skin and provocation tests, which should be postponed until after birth because of possible, though rare, anaphylactic reactions . The same applies to food and other challenge tests. Despite the fact that there are no harmful effects of patch testing during pregnancy or lactation known, most physicians deter testing as general precaution, and furthermore because test results can interfere with immunological changes due to pregnancy .
Testing For Allergies During Pregnancy
Skin testing is usually the go-to for doctors to test for allergies, but they dont typically do it when youre pregnant because of the theoretical risk for an allergic reaction, Kleva says. Instead, your doctor will give you a blood test, which Kleva says is almost as good as a skin test. If youre struggling with shortness of breath or asthma symptoms, your doctor may also recommend a breathing test called spirometry or pulmonary function tests , Parikh says.

Howpregnancy Affects Allergies And Asthma
Seasonalallergies occur when the bodys immune system overreacts to certain otherwisecommon environmental substances, such as pollen and dust. When people withallergies breathe in such a substance which for them is an allergen theirbodies see it as a foreign invader and mounts an immune response. When thishappens, the body produces multiple inflammatory chemicals which can causeclassic allergic reactions, such as:
Inflammation and swellingof the sinuses
Itchy, watery eyes
Sore, itchy throat
Runny nose
Antihistaminesand saline nasal spray can help can help control mild symptoms, while moderateto severe allergies require other therapies, such as nasal steroid sprays.
Asthma and seasonalallergy symptoms may worsen, improve, or remain unchanged during pregnancy.

For example, pregnancy induces swelling of the nasal mucosa, the innerlining of the nose. Inflammation can lead to pregnancy rhinitis, or nasalcongestion and a runny nose during pregnancy.

Some oral antihistamines, like Allegra , Benadryl , Chlor-Trimeton , Claritin , and Zyrtec appear to be safe after the first trimester, safe meaning they have caused no known harm in studies that have been done. Avoid antihistamines combined with a decongestant.

Dont start allergy shots during pregnancy. If women are already taking them when they become pregnant, they can continue.

Are My Allergies A Risk To My Baby
Allergies can affect your baby, but rarely directly. Because the placenta works like a filter, your blood never enters your babys body.
This is good news because it means your baby will not get your allergy this way, will likely not be affected if you eat something they are allergic to, and will not be affected by all the white blood cells racing around your body.
Eating certain foods during pregnancy will not increase your childs risk of an allergy. The idea that eating peanuts will give your baby a peanut allergy isnt just an old wives tale its the opposite of the truth .
Eating a varied diet during pregnancy, including common allergy triggers, reduces your babys chance of allergies.
Some people maintain overeating of a food type during pregnancy could cause a food aversion or intolerance, but this has not been confirmed. If you are in doubt or worried your baby will not be able to handle some of your favorite foods after birth, just remember to eat a varied diet.
When it comes to allergic reactions, these can absolutely affect your baby, though. If you suffer an anaphylactic shock, the lack of oxygen can affect your baby as well as you. The same goes for asthma and other breathing reactions .
IMPORTANT
If you suffer a food reaction, the loss of water and nutrients could hurt your baby. Vomiting, diarrhea, and just plain discomfort could all be a sign you are not digesting foods well.
