What preservatives are in allergy shots


An allergy can be defined as an abnormal physical reaction to substances, called allergens, that are harmless to most people. Pollens, home dust mites, mold spores, animal danders, foods, drugs, dyes, cosmetics, perfumes, and stinging insects are common sources of allergens. These allergens can enter the body in diverse ways: pollens, home dust, and mold spores are inhaled; food allergens are swallowed; poison ivy and cosmetics produce symptoms in allergic people by touch; certain drugs and insect venoms enter the body by being injected.

The immune system produces antibodies as a defense against infection and other diseases.

In allergic people, an excess of a certain antibody called IgE is often produced. These IgE antibodies, which are considered immediate hypersensitivity antibodies, react and release inflammatory chemicals when they contact allergens and then allergy symptoms are produced. Immediate hypersensitivity generally occurs within minutes or a hour of an exposure, and can be a life threatening emergency. Some types of allergic symptoms can happen with other antibodies such as IgA, IgG, and IgM.

These are considered delayed allergy and symptoms can happen up to 72 hours after exposure. The measurement of IgE, IgA, IgG, and IgM antibodies is the key to effective allergy diagnosis and treatment.


For an individual’s allergies to be appropriately treated and controlled, it is significant that the specific allergen(s) causing allergic symptoms be identified. The patient may select to do skin testing, a blood test, or both.

Skin tests can actually treat the symptoms of allergens that are breathed in and cannot be avoided as in molds, dust, mites, tree, grass and weed pollens. The blood test can measure a person’s IgG, IgM, IgE and IgA antibodies to a wide variety of allergens. A little sample of blood can be analyzed in the laboratory for a safe and precise diagnosis. Bloodspot testing available for some tests which is done by a simple finger stick at home. This test is extremely valuable especially for finding what foods the person may be allergic to.

At that point the person may select avoidance, skin testing for treatment and rotating the foods in the diet. Blood screening tests for allergies are available by clicking here. For further information you may call the office at 207-657-4325. Both skin tests and blood tests provide valuable information for keeping your allergies under control.


Here at Chelation Medical Middle we offer preservative free allergy testing using a specialized form of testing called Provocative / Neutralization. We are the only clinic in New England that offers preservative free allergy testing.

What preservatives are in allergy shots

This procedure for immunotherapy skin testing takes one or two days but it enables the patient to get immediate relief from their neutralizing doses and permits them to take their own allergy shots at home rather than coming to the office every week. If the patient comes from a distance, once testing is completed, antigens can be mailed to their home. We believe that preservatives in antigens can cloud the results of skin testing, and own taken the step to provide every of our antigens as preservative free. The normal preservative chemicals found in numerous other offices for testing, such as phenol and glycerin, is thus eliminated for our patients with chemical sensitivity.

The testing is exact and the benefits are great!

An allergy treatment program may include several phases for control of symptoms. Once the offending substance(s) own been identified, it may be possible to simply avoid those things in your environment that cause you to experience allergic symptoms.

Food allergies are commonly treated with avoidance. Numerous allergens are not avoidable as in the case of pollens, dust, mold spores, etc. Numerous symptoms can be controlled with «Allergy Shots». Allergy shots or «Immunotherapy» is prescribed when long-term protection against allergic reactions is needed to control symptoms. Immunotherapy consists of a series of injections which can be done at home generally once every four days. These injections contain little amounts of the offending allergen(s) which were identified by the skin tests.

This treatment is designed to neutralize the patients’ reactions against the substances to which they are allergic.


Allergic symptoms may take numerous diverse forms. Symptoms happen frequently:

In the Nose — Allergic Rhinitis or hay fever is associated with nasal itching, congestion, sneez­ing, post nasal drip and a runny, watery dis­charge. Every of these symptoms are cold-like and are sometimes not recognized as allergy.

Sinu­sitis is often a- complication of allergic rhinitis.

In the Eyes — Conjunctivitis symptoms are itch­ing, redness, swelling, and tearing.

In the Lungs — Asthma symptoms are shortness of breath, wheezing, tightness in the chest, and cough. Recurrent bronchial infections can be caused by allergies.

On the Skin — Hives (Urticaria) are itchy welts of varying sizes that may appear on the skin, lips, and inside the mouth and ears.

  1. Contact Dermatitis symptoms are a blistery rash and intense itching caused by substances such as poison ivy.

  2. Eczema appears as a dry, itchy rash often along creases of the skin but can also be found on most other parts of the body

In the Digestive Tract — With symptoms of stomach cramps, vomiting, and diarrhea (usually associated with sensitivity to foods).

In the Ears — As fluid in the middle ear or recurrent ear infections which can eventually result in some loss of hearing.

Foods maybe a culprit with chronic ear infections.

In the form of other disorders — Headaches, fatigue, hyperactivity, and depression can every be symptoms of allergy.

A Michigan State University researcher has found that a common food additive may be linked to a rise in food allergies.

Cheryl Rockwell, an assistant professor of pharmacology and toxicology in the College of Human Medicine, began studying the possible link between the synthetic food additive tert-butylhydroquinone, or tBHQ, nine years ago.

Now she has received an award from the National Institute of Environmental Health Sciences to continue her work.

The Outstanding New Environmental Scientist, or ONES, award comes with a $1.5 million, five-year grant to support her research.

Rockwell has dreamed of winning the award since she was a postgraduate student. She recently was notified that she was among only five researchers this year to be selected.

Approved by the U.S. Food and Drug istration in 1972, tBHQ is a preservative in numerous foods, such as cooking oil, nuts, crackers, waffles and breads. Often tBHQ is not listed on the label, Rockwell said.

Her research has shown that tBHQ causes T cells, a critical part of the body’s immune system, to release a set of proteins that can trigger allergies to such foods as nuts, milk, eggs, wheat and shell fish.

“I ponder of the immune system as a military force,” Rockwell said.

“Its occupation is to protect the body from pathogens, such as viruses. The T cells are the generals.”

Normally, the T cells release proteins, known as cytokines, that assist fight the invaders, she said, but when tBHQ was introduced in laboratory models, the T cells released a diverse set of cytokines that are known to trigger allergies to some foods.

Her studies showed that when tBHQ was present, the T cells started behaving differently.

“The T cells stopped acting as soldiers in the defense against pathogens and started causing allergies, Rockwell said.

“What we’re trying to discover out now is why the T cells are behaving this way.”

The expanded use of tBHQ, she said, parallels a rise in food allergies and an increase in the severity of some allergic reactions.

With her ONES grant, Rockwell plans to study a signaling pathway she has identified in cells that appears to frolic a role in causing the food allergies when tBHQ is present. She hopes to identify other chemicals that trigger that same signaling pathway.

“We ponder there could be fairly a few,” she said, including lead and cadmium.

The National Institute of Environmental Health Sciences created the ONES program to support researchers early in their careers and conduct innovative research to study how the environment influences human health.

“This project is my baby,” she said.

“I need to hold it going.”

There are 2 types of contact dermatitis.

Irritant dermatitis: This is the most common type. It is not caused by an allergy, but rather the skin’s reaction to irritating substances or friction. Irritating substances may include acids, alkaline materials such as soaps and detergents, fabric softeners, solvents, or other chemicals. Extremely irritating chemicals may cause a reaction after just a short period of contact.

Milder chemicals can also cause a reaction after repeated contact.

People who own atopic dermatitis are at increased risk of developing irritant contact dermatitis.

Common materials that may irritate your skin include:

  1. Long-term exposure to wet diapers
  2. Hair dyes
  3. Pesticides or weed killers
  4. Cement
  5. Rubber gloves
  6. Shampoos

Allergic contact dermatitis: This form of the condition occurs when your skin comes in contact with a substance that causes you to own an allergic reaction.

Common allergens include:

  1. Nail polish, hair dyes, and permanent wave solutions.
  2. Fragrances in perfumes, cosmetics, soaps, and moisturizers.
  3. Nickel or other metals (found in jewelry, watch straps, metal zips, bra hooks, buttons, pocketknives, lipstick holders, and powder compacts).
  4. Antibiotics, such as neomycin rubbed on the surface of the skin.
  5. Adhesives, including those used for untrue eyelashes or toupees.
  6. Fabrics and clothing, including both materials and dyes.
  7. Rubber or latex gloves or shoes.
  8. Balsam of Peru (used in numerous personal products and cosmetics, as well as in numerous foods and drinks).
  9. Preservatives commonly used in prescription and over-the-counter topical medicines.
  10. Poison ivy, poison oak, poison sumac, and other plants.
  11. Formaldehyde, which is used in a wide number of manufactured items.

You will not own a reaction to a substance when you are first exposed to the substance. However, you will form a reaction after future exposures. You may become more sensitive and develop a reaction if you use it regularly. It is possible to tolerate the substance for years or even decades before developing allergy. Once you develop an allergy you will be allergic for life.

The reaction most often occurs 24 to 48 hours after the exposure. The rash may persist for weeks after the exposure stops.

Some products cause a reaction only when the skin is also exposed to sunlight (photosensitivity). These include:

  1. Sulfa ointments
  2. Sunscreens
  3. Some perfumes
  4. Shaving lotions
  5. Coal tar products
  6. Oil from the skin of a lime

A few airborne allergens, such as ragweed, perfumes, vapor from nail lacquer, or insecticide spray, can also cause contact dermatitis.

In recent years, however, as consumer demand for natural foods has risen, food manufacturers own been replacing synthetic additives with natural ones derived from plants, insects and other animal products.

These natural substances are more likely to provoke an allergic reaction because they contain proteins that our immune systems might react to, said Dr. Ronald Simon, an allergist and immunologist at Scripps Clinic Carmel Valley in San Diego, who reviewed the literature for UpToDate, a clinical information resource used by doctors.

These natural additives include substances love a red food dye called carmine or cochineal extract, which is made from insects; a yellow dye made from the fruit of the annatto tree; psyllium, a source of dietary fiber derived from seed husks; and guar gum, which is made from a bean and is used as a binder and emulsifier in food and drugs.

Every of these own been implicated in rare cases of anaphylaxis.

Allergic reactions own also been reported from carrageenin, a thickener derived from seaweed; the jelling agent pectin; gelatin; and Mycoprotein, a fermented fungus used as a meat substitute and marketed under the brand name Quorn.

Our immune system recognizes these natural proteins, Dr. Simon said, “because it evolved to protect us against invading organisms and to recognize protein structures in fungi and bacteria or cancer cells.” He said the immune system is less likely to recognize a synthetic additive.

(Dr. Simon acknowledged he has served as a consultant on food additives for the International Association of Color Manufacturers.)

Dr. Swerlick, the dermatologist who treated Ms. Eisenberg, agreed that reactions to synthetic additives are rare and not well understood, making them even more hard to identify. In a 2013 paper, he described 11 patients he had seen over a five-year period, every of whom came in with chronic skin disorders that cleared up significantly when drugs containing coloring were replaced by dye-free medications. (Skeptics tell that hives generally come and go and there is no proof that the removal of dyes caused the patients’ skin to clear.)

Each of Dr.

Swerlick’s cases was slightly diverse, he said, so it was “a bit of detective work.” One 61-year-old patient had chronic skin problems on his hand, but the rash flared up suddenly, shortly after he refilled a prescription for diabetes pills and noticed that the color had changed from off-white to dark purple. The new pills, it turned out, contained a blue dye. Another patient, a 42-year-old man, had suffered from a rash for almost a year but noticed it resolved when he went on vacation and left his toothpaste, which contained a blue dye, at home.

Many of the patients had “a drug allergy list that’s 20 drugs long,” Dr.

Swerlick said. “You realize they can’t be allergic to every these medications. It must be something common to every of them, love a dye. That’s one of the clues.”

Thimerosal (Ethylmercury) Frequently Asked Questions


What is thimerosal?
Thimerosal is a mercury-based preservative that has been used for decades in the United States in multi-dose vials (vials containing more than one dose) of medicines and vaccines.

Why is thimerosal used as a preservative in vaccines?
Thimerosal is added to vials of vaccine that contain more than one dose to prevent the growth of bacteria and fungi in the event that they get into the vaccine.

This may happen when a syringe needle enters a vial as a vaccine is being prepared for istration. Contamination by germs in a vaccine could cause severe local reactions, serious illness or death. In some vaccines, preservatives are added during the manufacturing process to prevent microbial growth.

How does thimerosal work in the body?
Thimerosal does not stay in the body a endless time so it does not build up and reach harmful levels.

When thimerosal enters the body, it breaks below, to ethylmercury and thiosalicylate, which are easily eliminated.

Is thimerosal safe?
Thimerosal has a proven track record of being extremely safe. Data from numerous studies show no convincing evidence of harm caused by the low doses of thimerosal in vaccines.

What are the possible side-effects of thimerosal?
The most common side-effects are minor reactions love redness and swelling at the injection site. Although rare, some people may be allergic to thimerosal. Research shows that most people who are allergic to thimerosal will not own a reaction when thimerosal is injected under the skin (Wattanakrai, 2007; Heidary, 2005).

Does thimerosal cause autism?
Research does not show any link between thimerosal in vaccines and autism, a neurodevelopmental disorder.

Although thimerosal was taken out of childhood vaccines in 2001, autism rates own gone up, which is the opposite of what would be expected if thimerosal caused autism.

Do MMR vaccines contain thimerosal?
No, measles, mumps, and rubella (MMR) vaccines do not and never did contain thimerosal. Varicella (chickenpox), inactivated polio (IPV), and pneumococcal conjugate vaccines own also never contained thimerosal.

Do every flu vaccines contain thimerosal?

Influenza (flu) vaccines are currently available in both thimerosal-containing and thimerosal-free versions. The entire quantity of flu vaccine without thimerosal as a preservative at times has been limited, but availability will increase as vaccine manufacturing capabilities are expanded. In the meantime, it is significant to hold in mind that the benefits of influenza vaccination outweigh the theoretical risk, if any, of exposure to thimerosal.

How can I discover out if thimerosal is in a vaccine?
For a finish list of vaccines and their thimerosal content level, you may visit the U.S.

Food and Drug istration. Additionally, you may enquire your health care provider or pharmacist for a copy of the vaccine package insert. It lists ingredients in the vaccine and discusses any known adverse reactions.
