The human body has an immune system and an allergy is a reaction of this immune system to some allergen. The allergen might be either in the environment or food products. These allergens might be otherwise harmless to people in general. These may vary from being as general as dust, pollen, animal dander or some food products. This might be season specific and at times even location specific. This is largely due to the environmental conditions specific to a certain season or area. An exposure to these triggers off an allergic reaction which again manifests in various ways. Some of these manifestations are mere, sneezing, water from the eyes, sniffling, sore throat , to as serious as rashes and in extreme cases even anaphylactic shock. Anaphylactic shock can result only in case the allergy is left untreated and the exposure to the allergen which irritates your immune system continues undeterred. Therefore medical advice must be sought for allergies during pregnancy.
Allergies during pregnancy might be pre existing or in some cases might have been pregnancy induced. Allergies are commonly associated with pregnancies. If you are battling allergy problems from before getting pregnant and have been on medication for it, make sure to consult your physician whether or not you can continue taking them. This is relevant to both over the counter drugs as well as homeopathic medication. Most of the over the counter medicines if being taken from before conception are considered safe. However one must not take the risk of taking them without consulting your physician. Anti- allergy shots are also considered safe again if they are being taken from before your getting pregnant. Most physicians believe that starting a new anti- allergic medication or shot to cure allergy during pregnancy is not a very good idea. Such introductions may lead to reactions of the immune system that might be for the worse. Some anti- allergy drugs contain pseudoephedrine. You must avoid taking these medications especially in the first trimester of your pregnancy since they might affect the baby.
Medication can be taken once clinical advice has been sought, meanwhile symptomatic relief of rhinitis , that is watering nose, nasal decongestion and sneezing can be sought. One can use normal saline nasal drops. However it is best to avoid having an allergy problem in the first place. Any allergens that have been identified to be cause of your allergic reaction must be avoided.
