What to take for allergies when your pregnant

While it’s clear that a mother’s diet influences the health of her unborn kid, there’s a lack of evidence that eating specific foods can prevent certain illnesses and conditions in her kid.

Said Dr. Stephen Wasserman, an asthma and allergy specialist at UC San Diego, «There is not going to be one diet or one set of behaviors for every people.

People bring their genetics to the table and one person’s excellent is another person’s bad.»

Doctors consent that pregnant women should purpose for a well-balanced diet and make certain they get sufficient protein, which is the basis for a growing fetus’ cells and tissues. But some go beyond that:

Some obstetricians and others urge mothers to eat fish wealthy in the omega-3 fatty acids thought to promote development of a healthy nervous system in the fetus. Most include the caveat that they need to avoid going overboard, because fatty fish also tend to own higher levels of mercury, which is toxic to immature brains.

A limited number of studies propose a diet wealthy in vitamin D, the sunshine vitamin, may protect against allergies. Still, said Dr. Christian Pettker, medical director of labor and birth at Yale-New Haven Hospital, «we are actually learning that more and more women own vitamin D deficiency than we previously suspected For these reasons, more obstetricians are advocating a diet that accounts for a healthy quantity of vitamin D, and if vitamin D deficiency is suspected, this should be looked into.» However, said Dr.

Harvey Leo, a pediatric allergist at the University of Michigan’s Middle for Managing Chronic Disease, because vitamin D is predominantly made by sun exposure, «a mother’s diet may not make a difference at every. It may be the mother’s sun exposure.»

Both Omega-3 fatty acids and vitamin D decrease inflammation, and asthma and allergies are inflammatory disorders, so Dr. Katherine Sherif, Director of the Middle for Women’s Health and associate professor of internal medicine at Drexel University College of Medicine in Philadelphia, recommended pregnant women take Omega-3 supplements and vitamin D supplements daily.

Some studies propose a Mediterranean diet wealthy in unused fruits, vegetables, legumes and lean protein could protect against allergies. However, physicians who are sticklers for evidence, rather than anecdotes, tell the benefits to the unborn kid aren’t proven. «The Mediterranean diet is sort of love vitamin C: It’s probably not bad, but probably as numerous studies tell it’s beneficial as tell it’s not,» said Dr. Dana Wallace, an allergist in Fort Lauderdale and the incoming president of the American College of Allergy, Asthma and Immunology.

Probiotics, which urge excellent bacteria to take up residence in the digestive system, may discourage the development of allergies, said Dr. Leonard Bielory, an allergist and immunologist now at the Middle for Environmental Prediction at Rutgers University in New Jersey. Bielory was the primary investigator in a meta-analysis that suggested children may not be as allergic «if they own probiotics introduced into the diet or the mother’s diet while pregnant.»

Getting assist for allergies

See a GP if you ponder you or your kid might own had an allergic reaction to something.

The symptoms of an allergic reaction can also be caused by other conditions.

A GP can assist determine whether it’s likely you own an allergy.

If they ponder you might own a mild allergy, they can offer advice and treatment to assist manage the condition.

If your allergy is particularly severe or it’s not clear what you’re allergic to, they may refer you to an allergy specialist for testing and advice about treatment.

How to manage an allergy

In many cases, the most effective way of managing an allergy is to avoid the allergen that causes the reaction whenever possible.

For example, if you own a food allergy, you should check a food’s ingredients list for allergens before eating it.

What to take for allergies when your pregnant

There are also several medicines available to help control symptoms of allergic reactions, including:

  1. lotions and creams, such as moisturising creams (emollients) – these can reduce skin redness and itchiness
  2. decongestants – tablets, capsules, nasal sprays or liquids that can be used as a short-term treatment for a blocked nose
  3. antihistamines – these can be taken when you notice the symptoms of a reaction, or before being exposed to an allergen, to stop a reaction occurring
  4. steroid medicines – sprays, drops, creams, inhalers and tablets that can assist reduce redness and swelling caused by an allergic reaction

For some people with extremely severe allergies, a treatment called immunotherapy may be recommended.

This involves being exposed to the allergen in a controlled way over a number of years so your body gets used to it and does not react to it so severely.

What causes allergies?

Allergies occur when the body’s immune system reacts to a specific substance as though it’s harmful.

It’s not clear why this happens, but most people affected own a family history of allergies or own closely related conditions, such as asthma or eczema.

The number of people with allergies is increasing every year.

The reasons for this are not understood, but 1 of the main theories is it’s the result of living in a cleaner, germ-free environment, which reduces the number of germs our immune system has to deal with.

It’s thought this may cause it to overreact when it comes into contact with harmless substances.

Is it an allergy, sensitivity or intolerance?

Immunotherapy and influenza vaccine

Allergen immunotherapy (allergy shots) is often effective for those patients in whom symptoms persist despite optimal environmental control and proper drug therapy.

Allergen immunotherapy can be carefully continued during pregnancy in patients who are benefiting and not experiencing adverse reactions.

What to take for allergies when your pregnant

Due to the greater risk of anaphylaxis with increasing doses of immunotherapy and a delay of several months before it becomes effective, it is generally recommended that this therapy not be started during pregnancy.

Patients receiving immunotherapy during pregnancy should be carefully evaluated. It may be appropriate to lower the dosage in order to further reduce the chance of an allergic reaction to the injections.

Influenza (flu) vaccine is recommended for every patients with moderate and severe asthma.

There is no evidence of associated risk to the mom or fetus.


Where a substance causes unpleasant symptoms, such as diarrhoea, but does not involve the immune system.

People with an intolerance to certain foods can typically eat a little quantity without having any problems.

Here are answers to some of the most common questions pregnant patients enquire their allergist.


A reaction produced by the body’s immune system when exposed to a normally harmless substance.


The exaggeration of the normal effects of a substance.

For example, the caffeine in a cup of coffee may cause extreme symptoms, such as palpitations and trembling.

Can allergy medications safely be used during pregnancy?

Antihistamines may be useful during pregnancy to treat the nasal and eye symptoms of seasonal or perennial allergic rhinitis, allergic conjunctivitis, the itching of urticaria (hives) or eczema, and as an adjunct to the treatment of serious allergic reactions, including anaphylaxis (allergic shock).

With the exception of life-threatening anaphylaxis, the benefits from their use must be weighed against any risk to the fetus. Because symptoms may be of such severity to affect maternal eating, sleeping or emotional well-being, and because uncontrolled rhinitis may pre-dispose to sinusitis or may worsen asthma, antihistamines may provide definite benefit during pregnancy.

Chlorpheniramine (ChlorTrimeton®), and diphenhydramine (Benadryl®) own been used for numerous years during pregnancy with reassuring animal studies. Generally, chlorpheniramine would be the preferred choice, but a major drawback of these medications is drowsiness and performance impairment in some patients..

What to take for allergies when your pregnant

Two of the newer less sedating antihistamines loratadine (Claritin®), and cetirizine (Zyrtec®) own reassuring animal and human study data and are currently recommended when indicated for use during pregnancy.

The use of decongestants is more problematic. The nasal spray oxymetazoline (Afrin®, Neo-Synephrine® Long-Acting, etc.) appears to be the safest product because there is minimal, if any, absorption into the blood stream. However, these and other over-the-counter nasal sprays can cause rebound congestion and actually worsen the condition for which they are used.

Their use is generally limited to extremely intermittent use or regular use for only three consecutive days.

Although pseudophedrine (Sudafed®) has been used for years, and studies own been reassuring, there own been recent reports of a slight increase in abdominal wall defects in newborns. Use of decongestants during the first trimester should only be entertained after consideration of the severity of maternal symptoms unrelieved by other medications. Phenylephrine and phenylpropanolamine are less desirable than pseudophedrine based on the information available.

A corticosteroid nasal spray should be considered in any patient whose allergic nasal symptoms are more than mild and final for more than a few days.

These medications prevent symptoms and lessen the need for oral medications. There are few specific data regarding the safety of intranasal corticosteroids during pregnancy. However, based on the data for the same medications used in an inhaled form (for asthma), budesonide (Rhinocort®) would be considered the intranasal corticosteroid of choice, but other intranasal corticosteroids could be continued if they were providing effective control prior to pregnancy.

When women with asthma and allergies get pregnant, one-third discover their asthma and allergies improved, one-third discover they worsen and one-third remain unchanged.

Should I continue my allergy shots during pregnancy?

It is appropriate to continue allergy shots during pregnancy in women who are not having reactions to the shots, because they may lessen your allergic or asthma symptoms.

There is no evidence that they own any influence on preventing allergies in the newborn. It is not generally recommended that allergy shots be started during pregnancy.

To summarize: It is extremely significant to monitor closely any asthma or allergic problems during your pregnancy. In the vast majority of cases, you and your kid can glance forward to a excellent outcome, even if your asthma is severe, so endless as you follow your doctor’s instructions carefully. At the extremely first signs of breathing difficulty, call your doctor.

Remember the harm of providing an inadequate supply of oxygen to your baby is a much greater risk than taking the commonly used asthma medications.

The best way to take control of your allergies and own a healthy pregnancy is to speak with an allergist.

3, 2010— — Sitting below to a meal can be daunting for an expectant mom weighing conflicting recommendations about which foods are excellent for her unborn kid — and which might subject that kid to long-term ills love allergies to peanuts and other foods.

«We own a tendency to beat pregnant women over the head with ‘do this, don’t do this,'» said obstetrician-gynecologist Dr. Laura Riley, medical director of labor and delivery at the Harvard-affiliated Massachusetts General Hospital.

«We always desire people to own a balanced diet that includes protein, fat and carbohydrates. We don’t ponder pregnant women should take any one thing out of their diet.»

But just as dietary advice for weight loss changes as new scientific information becomes available, so, too, does dietary advice for moms-to-be about how their eating shapes their future sons’ and daughters’ health.

The advice has been particularly tricky with honor to peanut allergy, a potentially fatal condition that affects an estimated 1 percent to 2 percent of children.

The incidence has gone up in the final decade, although scientists can’t tell why.

From 1998 to 2000, the American Academy of Pediatrics and the British Committee on Toxicology recommended that in families where parents or siblings own allergies, women avoid peanuts during pregnancy and breast-feeding. But the data for these recommendations was scant and scientific studies yielded conflicting findings: Some said early exposure might be protective, others, harmful.

In 2008, the AAP reversed its position. Similarly, the European panel reversed its recommendation to stay away from peanuts during pregnancy and breastfeeding.

It now appears that in families with lots of allergies, it makes some sense for mothers-to-be to go simple on the peanuts, because of new research suggesting heavy consumption, particularly tardy in pregnancy, might set the stage for peanut allergies.

But for most families, doctors tell there’s no evidence that pregnant moms’ peanut eating will produce an allergic baby — or that avoiding peanuts will guarantee a healthier one.

To assist clarify the issues, the Consortium of Food Allergy Research studied the relationship between maternal diet and childhood allergies. The researchers, led by Dr. Scott H.

What to take for allergies when your pregnant

Sicherer of the Jaffe Food Allergy Institute at Mount Sinai School of Medicine in New York, followed 512 infants with food allergies to see if they became allergic to peanuts over time.

The investigators from Mount Sinai, Duke University in Durham, N.C., Johns Hopkins in Baltimore, National Jewish Health in Denver and Arkansas Children’s Hospital in Little Rock, also asked the mothers about their prenatal eating.

In results published online Oct. 29 in the Journal of Allergy and Clinical Immunology, which will appear in the December print issue, they reported that the more that a mom consumed peanuts in the third trimester of her pregnancy, the greater the chances her baby would test positive for sensitivity to peanuts.

However, sensitivity doesn’t equate to peanut allergy, «just an increased risk,» Sicherer said.

At enrollment, the children were ages 3 months to 15 months, too young for food challenges typically used to establish allergies.

The study authors said the youngsters would own to be monitored over time to determine if they developed peanut allergies later.

Sicherer also qualified the findings by saying the study involved only families with allergy histories, so the findings might not apply to the general population. Also, he said the study is observational, which means it doesn’t prove cause and effect.

Nevertheless, several experts called the results significant, but not practice-changing.

«This is an area that deserves more investigation and more studies,» said Dr. Neeta Ogden, an adult and pediatric allergist in private practice in Closter, N.J. «I’ve suspected in my own clinical practice, based on anecdotal evidence, that there has been some association. A study love this puts it on our radar for pregnant women that perhaps they should be consuming peanuts with caution, especially when they’re in their third trimester.»

Symptoms of an allergic reaction

Allergic reactions generally happen quickly within a few minutes of exposure to an allergen.

They can cause:

  1. a red, itchy rash
  2. red, itchy, watery eyes
  3. sneezing
  4. a runny or blocked nose
  5. wheezing and coughing
  6. worsening of asthma or eczema symptoms

Most allergic reactions are mild, but occasionally a severe reaction called anaphylaxis or anaphylactic shock can happen.

This is a medical emergency and needs urgent treatment.

Common allergies

Substances that cause allergic reactions are called allergens.

The more common allergens include:

  1. latex – used to make some gloves and condoms
  2. insect bites and stings
  3. grass and tree pollen – an allergy to these is known as hay fever (allergic rhinitis)
  4. animal dander, tiny flakes of skin or hair
  5. food – particularly nuts, fruit, shellfish, eggs and cows’ milk
  6. medicines – including ibuprofen, aspirin and certain antibiotics
  7. dust mites
  8. mould – these can release little particles into the air that you can breathe in
  9. household chemicals – including those in detergents and hair dyes

Most of these allergens are generally harmless to people who are not allergic to them.
