What happens if allergy serum isnt refrigerated
Many people benefit from allergy shots for many years after going through a full course of shots. Sublingual allergy drops are safer than allergy shots, more convenient, and offer long-term protection for both allergies and asthma. Allergy shots and allergy drops are safe, and side effects are usually mild. Common side effects of allergy shots include: Itching, swelling, and redness at the place where the shot was given.
How long will it take to feel better on allergy shots? Some patients will notice an early improvement of symptoms within several weeks during the build up phase, but it may take as long as 6 to 12 months on the maintenance dose to see a significant improvement.
Severe pain at the injection site. Blistering at the injection site. Muscle aches. Skin rash, severe itching, or hives. How do I get started on sublingual immunotherapy? Your Raleigh Capitol ENT doctor will take a medical history, complete a focused physical examination, and then order specific allergy testing, usually in the form of allergy skin tests.
Once the evaluation and testing are completed, your physician will discuss specific treatment options with you and guide you in your treatment decisions. If you choose to begin sublingual immunotherapy, your specific treatment kit will be prepared, usually within one week.
You will come to the clinic and complete your consent form, then take the first oral dose in the clinic. You may then take your treatment vials with you for administration of daily doses at home. Our allergy department staff will provide you with complete dosing instructions and renewal instructions.
The staff will be available during routine office hours for phone advice concerning your sublingual immunotherapy. The Raleigh Capitol ENT physicians are available for emergency consultation after hours and on weekends. Is there a minimum age for use of SLIT? There are no age restrictions for sublingual immunotherapy, although it is rare to begin any form of immunotherapy before age two. How will the dosing proceed? At the week point, you will begin a once-a-day dosing regimen with three drops as the standard maintenance dose.
This three drop-per-day dose will be continued for control of your allergies. The usual treatment course is three to four years, at which time a re-evaluation will be recommended. If you are doing well on maintenance immunotherapy, Your Raleigh Capitol ENT physician will want to see you in the clinic about every six to 12 months for a brief follow-up visit.
How will the drops be administered? The allergen extract is provided in convenient amber-glass bottles with a dropper mechanism that allows easy dosing under the tongue. Dosing should be done in the morning. Drops are placed under the tongue and held there for two minutes, then swallowed. However, I am afraid there may not be a definitive answer for you.
There is no question that heating does diminish the allergen content of extracts. I have copied below a scientific abstract from the Journal of Allergy and Clinical Immunology addressing this issue. We have known that this effect occurs, but from a practical standpoint, it may be an impossible problem to solve.
It is common practice to mail extracts. Our guidelines 1 recognize this, and state: "In many cases, it might be necessary to administer allergen immunotherapy extract in another physician's office meaning a physician other than the one who prepared the extract.
This is done realizing that there may be a diminishment of the potency of the extract due to the fact that it is not cooled during the mailing. And, the same guidelines quite clearly state that "allergen immunotherapy extract should be stored at 4 degrees centigrade to reduce the rate of potency loss. They cite a study undertaken by the American Academy of Allergy, Asthma, and Immunology Immunotherapy and Allergy Diagnostic Committee designed to study the stability of a mixture of standardized extracts in four conditions of storage.
They did this with and without intermittent room temperature exposure with extracts diluted in normal saline or human serum albumin. They found different degrees of deterioration depending on the allergen as well as allergen mixture.
Thus the standard rate of deterioration could not be calculated. With these observations in mind, from a practical standpoint, the best advice that we can offer you is to do your best to assure that the extract is refrigerated as soon as you receive it, and maintain it in refrigerated storage until the patient arrives and the shot is administered. Since data looking at the rate of deterioration varies considerably between extracts and can even vary to a greater extent when allergens are mixed, we cannot tell you with any accuracy at this time how much potency is lost.
Of course, it would depend upon the degree of temperature, and we certainly do not know the temperatures during shipping. Joint Task Force on Practice Parameters.

A 3 , 4 , 5 , 6 The allergens for which immunotherapy is known to be effective are A 5 , 6 , 8 , 10 Hymenoptera venom, pollens, cat dander, dust mites, cockroach, and fungi. B 7 , 9 In patients who had received three to four years of immunotherapy, a marked reduction in allergy symptom scores and antiallergic medication usage, as well as an alteration in the natural course of allergic disease, was demonstrated.
A 11 Immunotherapy for allergic rhinitis may reduce the risk for later development of asthma in children. B 12 , 13 Early treatment with allergen immunotherapy in children who were sensitive only to house dust mites reduced development of sensitivity to other allergens.
C 14 Patients with severe, poorly controlled asthma are at higher risk for systemic reactions to immunotherapy injections than patients with stable, well-controlled asthma.
Strength of Recommendations Key clinical recommendation SOR labels References Allergen immunotherapy is effective in patients with allergic rhinitis, allergic conjunctivitis, allergic asthma, and allergic reactions to Hymenoptera venom.
Selection of Patients To make a definitive diagnosis of allergy, IgE-mediated, type I, immediate-hypersensitivity skin testing typically is performed by scratching diluted allergen into the skin surface or by injecting it intradermally. TABLE 1 Best Indications for Immunotherapy Allergic rhinitis, conjunctivitis, or allergic asthma History of a systemic reaction to Hymenoptera and specific IgE antibodies to Hymenoptera venom Patient wishes to avoid the long-term use or potential adverse effects of medications Symptoms are not adequately controlled by avoidance measures or medications Cost of immunotherapy will be less than cost of long-term medications.
Benefits Durham and colleagues 11 conducted a randomized, double-blind, placebo-controlled trial to look at effects in patients who had received three to four years of immunotherapy.
Standardization, Storage, and Mixing of Allergen Vaccines Ideally, vaccines should be standardized with a defined potency and labeled with a common unit.
Vaccine Administration The maintenance concentrate is the dose of vaccine that is considered to be therapeutically effective for each of its constituent components.
The risk of anaphylaxis is increased if the patient: Has a fever, is acutely ill, or has a newly reported illness. Document any adverse reactions. Safety Issues Allergen immunotherapy is safe, but the potential for an adverse reaction is always present. Figure 1 Example of informed consent form for allergen immunotherapy.
