How Can I Treat A Peanut Allergy
Carrying adrenaline and avoiding allergens are important steps, but small traces of peanuts can be found in many products. To build a tolerance to the point where you can actually eat peanuts without risk, you would need to follow a course of oral immunotherapy treatment .
OIT requires an individual to consume gradually increasing amounts of peanuts over a period of around 612 months. This process builds tolerance, reducing the chances your immune system will react to any peanut proteins in your body. With ongoing maintenance, you can substantially limit the risk of peanuts to yourself or to your child.
What Will The Doctor Do
If your doctor thinks you might have a nut or peanut allergy, he or she will probably send you to see a doctor who specializes in allergies. The will ask you about past reactions and how long it takes between eating the nut or peanut and getting the symptoms, such as hives.
The allergist may also ask whether anyone else in your family has allergies or other allergy conditions, such as eczema or asthma. Researchers aren’t sure why some people have food allergies and others don’t, but they sometimes run in families.
The allergist may also want to do a skin test. This is a way of seeing how your body reacts to a very small amount of the nut that is giving you trouble. The allergist will use a liquid extract of the nut that seems to be causing you symptoms.
During skin testing, a little scratch on your skin is made . That’s how just a little of the liquid nut gets into your skin. If you get a reddish, itchy, raised spot, it shows that you may be allergic to that food or substance.
Skin tests are the best test for food allergies, but if more information is needed, the doctor may also order a blood test. At the lab, the blood will be mixed with some of the food or substance you may be allergic to and checked for antibodies.
Is There Currently A Cure For Peanut Allergy
There is no cure for peanut allergies. Palforzia is a type of oral immunotherapy that is approved for use in treating peanut allergies. It is a daily medication that may reduce symptoms in some people who have a peanut allergy.
If you or your child experience severe reactions, it’s important that you talk to your doctor about whether you should have an EpiPen, and that you learn how to use it.
There are a number of small studies focusing on the use of oral immunotherapy for the treatment of peanut allergy. In one study, for example, participants were given increasing amounts of peanut flour to swallow on a daily basis, for a period of weeks to months. After this time period, an oral challenge to peanut was used to determine how much peanut the person could then tolerate without experiencing an allergic reaction.
Reported results of immunotherapy for treating peanut allergy:
- A few studies have shown that after children had undergone oral immunotherapy to peanut for many months, they could eat a large number of peanuts without experiencing an allergic reaction.
- It’s important to note that almost all of these children experienced some form of allergic reaction during the course of the oral peanut immunotherapy.
- There are a growing number of reports of children developing eosinophilic esophagitis as a side effect of oral immunotherapy.
If you are interested in immunotherapy, you can contact your allergist to weigh your risks and benefits.

Keeping A Record Of Your Nut Allergy Symptoms
Diagnosing an allergy can be difficult. If you think you or a child in your care might have an allergy, keeping a record of symptoms can help you and your doctor to understand what is causing them. Keep a diary that describes the symptoms, and when and where they occur. Your diary could include information about whether the symptoms occur:
- inside your home, outside or both
- for a short time or longer
- at night, during the day or when you wake up
- after you have had a particular food or drink
- after you have taken a herbal medicine.
How Are Peanut Allergies Managed What Is The Treatment For A Peanut Allergy
Strict avoidance of peanuts and prompt treatment of accidental ingestions are the mainstays of management of peanut allergy. The goals of treatment are to minimize the risk of accidental ingestion while maintaining adequate nutrition and an acceptable quality of life.
Although there is significant research focused on oral immunotherapy and desensitization protocols for peanut allergy, these treatment options are still not ready for widespread clinical use. There is also significant research involving a peanut patch, also known as epi-cutaneous immunotherapy.
Early studies of this patch have shown that by applying a patch containing peanut protein to the skin, it may be possible to make peanut allergic individuals less sensitive to peanut protein and it may protect certain peanut-allergic individuals from experiencing a reaction to an accidental peanut exposure. There are still many questions regarding this possible form of therapy and it is still not ready for widespread clinical use.
Peanut is a common food in the Unites States, and strict avoidance requires constant awareness of food labels and food ingredients. United States legislation requires all food companies to identify on labels whether their products contain the most common food allergens, including peanuts.

Weve Cracked How To Overcome Nut Allergies Claim Scientists
Cambridge team says it has developed breakthrough immunotherapy formula after five and a half years of trials on children
Scientists claim to have discovered a breakthrough treatment for nut allergies.
The team from Cambridge says it has developed an immunotherapy formula after five and a half years of trials on children.
The project resulted in a majority of youngsters allergic to peanuts being able to eat them without showing ill effects.
Researchers at the Wellcome Trust Clinical research facility at Addenbrookes Hospital, Cambridge, gave 99 children aged between seven and 16 a sample of peanut protein in powder form. They increased the dosage over six months until the youngsters were able to eat a whole nut without any adverse reactions.
Eighty-four per cent of patients could eat as many as five peanuts a day and more than 50 per cent managed 10.
Dr Andrew Clark and Dr Pamela Ewan hope the treatment will soon be available on the NHS.
Dr Clark said: This is a real first. Peanut allergies affect one million people in the UK. We have a large research group and we have been working on this for about 20 years.
So many people have this allergy and there are a number of deaths across the UK each year. Hopefully we can use this treatment in the NHS now.
One volunteer, Lena Barden, 11, of Histon, Cambs, said: I was nervous at first. I hated peanuts. Theyre disgusting and weird. But I was curious about what they tasted like.

Highly Purified Peanut Oil Contains Little Allergen
Refined peanut oils , have been shown to be safe in small studies. It is difficult to guarantee that an oil is sufficiently refined to remove all traces of peanut protein, which is the trigger for allergic reactions. Some restaurants use peanut oil for cooking, and peanut proteins may leach into the oil. Therefore, avoidance of peanut oil is advised. Little research has been done to prove safety of other nut oils, so avoidance is advised.

Symptoms Of Nut Allergies
Each persons immune system is different and peanut, tree nut and seed allergies can cause diverse signs and symptoms, ranging from mild to severe. Many food allergies do not cause severe symptoms, but they can be life threatening in some people and should be taken seriously.Some people have negative or adverse reactions to food that are not caused by allergies. These can be caused by factors such as food poisoning, toxic reactions or food sensitivities . Although these are not allergic reactions, they are often mistaken for allergies. Mild allergic symptoms that can occur before a severe allergic reaction include:
- raised red bumps of skin hives
- swelling of the lips
- tingling of the throat and mouth
- itchy skin and rash
- tightening of the throat
- digestive symptoms cramps, stomach pain, nausea or vomiting.
If you or a child in your care have experienced any of these symptoms after eating peanuts, tree nuts or seeds, the risk of having a severe reaction after eating that food is greater than usual. Ask your doctor to refer you to a clinical immunology or allergy specialist.
Do Allergies Reduce Life Expectancy
We found that allergic rhinitis patients had a decreased risk of heart attack, a decreased risk of stroke and, most strikingly, a decreased risk of all-cause mortality, said lead investigator Angelina Crans Yoon, MD, from the Department of Allergy and Clinical Immunology at the Kaiser Permanente Los Angeles Medical

Next Steps In Peanut Allergy Treatments
Ongoing treatment programs aim to refine the treatment process that grew from the LEAP study, says Dr. Hong. More than 50 children with an identified peanut allergy are in the program.
The minimal goal is to help these children achieve at least bite-proof tolerance to peanuts, meaning they can consume nearly two peanut kernels without a reaction, says Dr. Hong. That protects against an accidental nibble of a food with peanuts leading to a health emergency.
Many participants, however, see their immune system response change so much that they can eat peanut products, says Dr. Hong.
The key is the age of the participants, as reactions to food allergens typically are less severe in early childhood. Their immune system is so malleable, so flexible, that they can tolerate it, notes Dr. Hong. There is this narrow window where we can do this.
The series of peanut challenges given to participants involve tiny amounts of the food. In the initial treatment cycle, for example, the daily dose is 8 milligrams of peanut protein.
Small increases follow every two weeks if there are no setbacks, says Dr. Hong. The process takes at four to six months, with maintenance dosing then continuing for at least a year.
Every uptick in peanut butter dosage takes place in an allergists office in case theres a reaction. The child is monitored for an hour after the higher dose.
Learn About Food Allergy Desensitization
Food allergy desensitization is a specialized technique that is used to reduce the severity of food allergies. During this treatment, we will give you very small amounts of the foods that are triggering your allergies. Over time, we will gradually increase the amount of food that is included in your doses. This treatment will help you become used to these substances.
After you have completed your food allergy desensitization treatment, you will be less likely to experience a severe anaphylactic reaction if you are accidentally exposed to peanuts or other triggering substances. Reducing your risk of developing severe allergic symptoms will relieve your anxiety and worries. You will feel more confident about going to work, attending school, or participating in social events with your family members and friends.

Will A Mild Peanut Allergy Become More Severe
It is commonly believed that each exposure to peanuts makes any subsequent allergic reaction increasingly worse. In reality, this belief is not completely accurate. As with all food allergies, how your immune system reacts is not entirely predictable. You could experience mild reactions for many years, and then suffer a severe reaction without any apparent reason. Conversely, a severe allergic reaction could be followed by a more moderate response.
Its a fact that food allergies are incredibly unpredictable, and no allergy sufferer should become comfortable with a series of mild reactions. And whats more, adults should also be cautious when it comes to food allergies. While children are more likely to suffer from allergies, an estimated 20% of adults with peanut allergies developed them after the age of 18.
What Is Tree Nut Desensitization
A tree nut allergy is one of the eight most common food allergies within the United States. From the almond, walnut, pecan, cashew, pistachio, and hazelnut to the lesser-known pine nuts, tree nuts come in a variety of shapes and sizes. Along with peanuts and shellfish, tree nuts are some of the more common food allergens that are linked to anaphylaxis as a result of consumption. It is important to be aware of what treatment or management options are available to you. Dr. Chacko and his staff are proud to offer tree nut desensitization as a new treatment option for those who suffer from tree nut allergies.

Treatment For Nut Allergies
The only treatment for food allergies is to avoid the food that causes your allergy. Even if you are careful, it is difficult to avoid all contact with a specific food. If you are at risk of a severe allergic reaction and you have been prescribed an adrenaline autoinjector , ASCIA recommends that you have an action plan for anaphylaxis. If you are not at high risk and have not been prescribed an adrenaline autoinjector, ASCIA recommends that you have an ASCIA action plan for allergic reactions. To assist with food avoidance, people with food allergies need to become familiar and comfortable with reading food labels. ASCIA has fact sheets to help you understand how to read food labels and what to avoid if you have a peanut, tree nut or seed allergy. Inaccurate diagnosis can lead to expensive and ineffective treatments, and unnecessary food avoidance, which can lead to malnutrition and food aversion, especially in children. Always speak to your doctor about your food allergy diagnosis and treatment options.
Reverse Your Food Allergies
You shouldnt let allergies prevent you from traveling, attending social events, and participating in other activities with your friends. Receiving food allergy desensitization treatments will decrease the severity of your allergies. Over time, this treatment will reduce your risk of experiencing an extreme allergic reaction.

Unproven Methods To Test For Allergies
A number of methods claim to test for allergies but have not been medically or scientifically proven. They can be costly and could lead to dangerous avoidance of certain foods. The Australasian Society of Clinical Immunology and Allergy , the organisation representing allergists in Australia, recommends that you do not use certain methods to have potential allergies tested. These methods include:
- cytotoxic food testing
- Vega testing.
Always speak with your doctor if you are thinking of using a complementary medicine or therapy to test for allergies.
What Is Peanut Oral Immunotherapy
Dr. Chacko is using a process known as oral immunotherapy, or OIT, to gradually desensitize patients to their allergens, so they no longer suffer allergic reactions. This therapy has been used to desensitize hundreds of patients.
The process is similar to that used to treat environmental allergies, such as hay fever. Instead of avoiding peanuts, children are given carefully measured amounts of peanut protein mixed with pudding, yogurt, or applesauce. The starting dose is typically around 0.1 mg. The dose is gradually increased to approximately 6 mg over several hours. If the patient is able to tolerate the protein, they are sent home with individual containers of the dose, which they must take every day. Patients must return to the clinic every couple of weeks where they receive ever-increasing doses. Eventually, patients graduate to eating peanut M& Ms or whole peanuts. Patients are considered desensitized when they can eat about 10 peanuts a day without a reaction. . Patients are required to continue on
OIT for food allergies is not without its critics. OIT has not been approved by the Food and Drug Administration . There are also questions regarding the long-term effectiveness of the treatment. The process is currently being evaluated in several clinical trials.
When Do Tree Nut Allergies Usually Develop
Tree nut allergies typically develop by age two, and a voluntary US allergy registry shows that 68 percent of children have reactions on their first known exposure. However, to become allergic to tree nuts, kids must first be exposed to them in some way. Experts are unsure of all the ways in which this could happen, but eating trace amounts or being exposed through broken skin are possibilities.
Kim says its unlikely but possible that a baby could have a reaction to breastmilk with nut protein in it if the mother is consuming a lot of nuts. The symptoms would be similar, he says. Sometimes infants are more likely to become lethargic.
What Is Nut Allergy
An allergy occurs when your body’s immune system, which normally fights infection, overreacts to a substance called an allergen. Most allergens are not obviously harmful and they have no effect on people who are not allergic to them. Allergic reactions to allergens can vary from mild to life-threatening.
Both peanuts and tree nuts can act as allergens, and can cause an allergic reaction in some people. When you come into contact with something that you are allergic to , a group of cells in your body, called mast cells, release a substance called histamine. Histamine causes the tiny blood vessels in the tissues of your body to leak fluid which causes the tissues to swell. This results in a number of different symptoms.
Strictly speaking, peanuts are not nuts, they are legumes, in the same family as peas and beans. Peanuts grow underground whereas other nuts grow on trees. The word nut in this leaflet can mean either tree nuts or peanuts.
