allergies and pregnancy


Any parent having a kid allergic to peanuts would know how difficult their lives could get along with their children’s’. Shopping food items could take hours as every label on the food packet needs to be checked before the purchase is made so that it is ensured that there is no trace of peanuts. Peanut free food needs to be arranged with such children’s school in later course of time and also in case of the child’s birthday party. Such things could at times become more than just a night mare. Peanut allergies are quite common and sometimes prove as fatal allergies for the child. Few kids are very sensitive to peanuts and can get the same just by coming into contact with some other’s skin that has the allergy. Peanut allergies could lead to things like anaphylactic shock which could be a severe allergic reaction proving fatal.

Until the child reaches around the age of two or sometimes three, peanut allergies are not diagnosed. Parents having history of peanut allergies in their family are advised to wait for at least until the time when the child reaches the age of three, before peanuts and items containing peanuts, can be given to them. Pregnant mothers are often advice about not eating peanuts, especially in their third trimester despite the fact of hereditary allergy of peanuts existing or not.

The main reason for any allergy relating to peanuts to develop is by getting into contact with small traces of peanuts. This makes the child to later have severe allergic reactions when peanuts are consumed. Initial sensitizations could occur right from the time of pregnancy. It has been seen that very little amount of peanut protein could cross the placenta. Recent studies have revealed that in case of consuming peanuts or items consuming peanuts during pregnancy could develop the allergy in the child in the later years. This was compared to women who consumed peanuts and those who did not.

It doesn’t mean that you need to totally ignore peanuts at all costs, especially when there are no instances of nut allergies in your family. Factually, peanuts and items with peanut factor are quite beneficial to yourself and your baby. Peanuts are sources of proteins and folic acid, which is significant to a growing baby. Peanut butter or standalone peanuts are said to help in getting rid of morning sickness during the first trimester of pregnancy tenure. Every woman should know that, many women who had no instances of peanut related allergies in their families and hence consumed excessive amounts of peanuts and related food stuff, later delivered babies who were prone to peanut allergies.

Before saying a stern no to jelly sandwiches and peanut butter, ensure that you have a word with your doctor. Your doctor would be helpful in creating a well balanced and healthy eating plan for you for your entire tenure. You would have to mention about your family history of peanuts allergies and matters concerning the same. If any woman is uncomfortable eating peanuts, she need not change her mind about the same as event woman for that matter has the rights to make decisions about her child and her body.

allergies and pregnancy


Rhinitis during pregnancy can be due to allergic rhinitis, sinusitis, or non-allergic rhinitis. If the woman has had allergic rhinitis prior to pregnancy, this could worsen, stay the same, or even improve. This change in symptoms may be dependent upon many factors, including the presence of seasonal allergens and increase in pregnancy hormones.

Non-allergic rhinitis in pregnancy may also be due to an increase in pregnancy hormones, leading to nasal congestion, runny nose and post nasal drip. This is called “rhinitis of pregnancy”. The symptoms may mimic allergies, but since they are non-allergic in nature, do not respond to anti-histamines.

The pregnant woman with rhinitis may be concerned about the safety of medications during pregnancy, and therefore avoid taking medications.

If avoidance of allergic triggers is not possible or successful, medications may be needed to control symptoms.

Diagnosis of Allergic Rhinitis During Pregnancy

Allergy testing includes skin testing or blood tests, called a RAST. In general, allergy skin testing is not done during pregnancy, given the small chance of anaphylaxis which may occur. Anaphylaxis during pregnancy, if severe, could result in a decrease in blood and oxygen to the uterus, possibly harming the fetus. Therefore, allergy testing is usually deferred during pregnancy, although a RAST would be a safe alternative if the results are needed during pregnancy.

Safety of Allergy Medications During Pregnancy

According to the Food and Drug Administration (FDA), no drugs are considered completely safe in pregnancy. This is because no pregnant woman would want to sign up for a medication safety study while she is pregnant. Therefore, the FDA has assigned risk categories to medications based on use in pregnancy.

Pregnancy category “A” medications are medications in which there are good studies in pregnant women showing the safety of the medication to the baby in the first trimester. There are very few medications in this category, and no asthma medications.

Category “B” medications show good safety studies in pregnant animals but there are no human studies available.

Pregnancy category “C” medications may result in adverse effects on the fetus when studied in pregnant animals, but the benefits of these drugs may out weight the potential risks in humans.

Category “D” medications show clear risk to the fetus, but there may be instances in which the benefits outweigh the risks in humans. And finally, category “X” medications show clear evidence of birth defects in animals and/or human studies and should not be used in pregnancy.

Before any medication is taken during pregnancy, the doctor and patient must have a risk/benefit discussion. This means that the benefits of the medication should be weighed against the risks – and the medication should only be taken if the benefits outweigh the risks.

Treatment of Rhinitis During Pregnancy

Nasal saline. Rhinitis of pregnancy tends not to respond to anti-histamines or nasal sprays. This condition seems to respond temporarily to nasal saline (salt water), which is safe to use during pregnancy (it is not actually a drug). Nasal saline is available over the counter, is inexpensive, and can be used as often as needed. Generally 3 to 6 sprays are placed in each nostril, leaving the saline in the nose for up to 30 seconds, and then blowing the nose.

Anti-histamines. Older anti-histamines, such as chlorpheniramine and tripelennamine, are the preferred agents to treat allergic rhinitis during pregnancy, and are both category B medications. Newer anti-histamines such as over-the-counter loratadine (Claritin/Alavert and generic forms) and prescription cetirizine (Zyrtec) are also pregnancy category B medications.

Decongestants. Pseudoephedrine (Sudafed, many generic forms) is the preferred oral decongestant to treat allergic and non-allergic rhinitis during pregnancy, although should be avoided during the entire first trimester, as it has been associated with infant gastroschisis. This medication is pregnancy category C.

Medicated nasal sprays. Cromolyn nasal spray (NasalCrom, generics) is helpful in treating allergic rhinitis if it is used before exposure to an allergen and prior to the onset of symptoms. This medication is pregnancy category B and is available over the counter. If this medication is not helpful, one nasal steroid, budesonide (Rhinocort Aqua), recently received a pregnancy category B rating (all others are category C), and therefore would be the nasal steroid of choice during pregnancy.

Immunotherapy. Allergy shots can be continued during pregnancy, but it is not recommended to start this treatment while pregnant. Typically the dose of the allergy shots is not increased, and many allergists will cut the dose of the allergy shot by 50 percent during pregnancy. Some allergists feel that allergy shots should be stopped during pregnancy, given the risk of anaphylaxis and possible danger to the fetus as a result. Other than anaphylaxis, there is no data showing that the allergy shots themselves are actually harmful to the fetus.
