Can Benadryl stop a peanut reaction?
Yes, Benadryl can help relieve peanut allergy symptoms associated with a mild reaction to peanuts. These symptoms include mild stomach discomfort, sneezing, itchiness of the mouth or nose, or a mild rash. However, Benadryl will not help with a severe allergic reaction such as anaphylaxis.
Peanut-containing Food Products
First, an injection of epinephrine (EpiPen or EpiPen Jr) should be given to reduce the severity of the reaction. Second, taking liquid diphenhydramine (Benadryl) at a dose of 5 mg for every 10 lb of body weight, up to a maximum dose of 75 mg, also is recommended.
Administer the antihistamine diphenhydramine (Benadryl, adults: 25 to 50 mg; children: 1 to 2 mg per kg), usually given parenterally. If anaphylaxis is caused by an injection, administer aqueous epinephrine, 0.15 to 0.3 mL, into injection site to inhibit further absorption of the injected substance.
There is actually no evidence that taking a daily non-sedating antihistamine masks the symptoms of anaphylaxis. The concern most allergists have about antihistamines is the cases in which they are used inappropriately to treat severe allergic reactions, or anaphylaxis, instead of epinephrine.
The only way to prevent a reaction is to avoid peanuts and peanut products altogether. But peanuts are common, and despite your best efforts, you're likely to come into contact with peanuts at some point. For a severe allergic reaction, you may need an emergency injection of epinephrine and to visit the emergency room.
Epicutaneous immunotherapy involves attaching an adhesive patch to the skin that contains a tiny dose of peanut protein. Similar to OIT, EPIT works by desensitizing patients to peanut and increasing tolerance. The patches contain very small quantities of peanut allergen – approximately 1/1000 of a peanut on it.
It normally takes about 30 minutes to work. Common side effects include feeling sleepy, dizzy or unsteady on your feet. You may also have difficulty concentrating and have a dry mouth.
Take a non-drowsy antihistamine, such as loratadine (Claritin), to treat mild symptoms. Be safe with medicines. Read and follow all instructions on the label. Mild symptoms include sneezing or an itchy or runny nose; an itchy mouth; a few hives or mild itching; and mild nausea or stomach discomfort.
In most people with peanut allergy, symptoms develop after substantially less than 1 peanut is ingested, and highly allergic people can react to trace amounts.
Mythbuster: Benadryl® can be used instead of epinephrine to treat anaphylaxis. FACT: NO, epinephrine is the first-line treatment for anaphylaxis. Antihistamines, like Benadryl®, do not reverse the symptoms of anaphylaxis and should not be used instead of epinephrine.
Why will antihistamines not stop anaphylaxis?
Although histamine is involved in anaphylaxis, treatment with antihistamines does not relieve or prevent all of the pathophysiological symptoms of anaphylaxis, including the more serious complications such as airway obstruction, hypotension, and shock.
Minor Allergic Reaction
In these cases, OTC or prescribed antihistamines such as diphenhydramine (Benadryl) may help reduce symptoms. These drugs can be taken after exposure to an allergy-causing food to help relieve skin redness, itching, or hives. However, antihistamines cannot treat a severe allergic reaction.
In hospital
an oxygen mask may be used to help breathing. fluids may be given directly into a vein to help increase blood pressure. additional medicines such as antihistamines and steroids may be used to help relieve symptoms. blood tests may be carried out to confirm anaphylaxis.
Symptoms of anaphylaxis can be mild, and they may go away on their own (most anaphylactic reactions will require treatment). But it's difficult to predict if or how quickly they will get worse. It's possible for symptoms to be delayed for several hours.
Treatment for severe allergic reaction at our ER
People with allergies are usually prescribed epinephrine autoinjectors to help control symptoms if they're exposed to an allergen. If you're with someone experiencing anaphylaxis, use the autoinjector and still seek medical help.
Currently, there is no cure for peanut allergies, but there are some therapies that can diminish the effects in some people, as well as emergency treatments for severe anaphylaxis.
More studies hint that it's possible to “train” the immune system to tolerate peanuts even if it doesn't want to by giving children with peanut allergies small amounts of peanuts over a period of time. But researchers now report that it may be possible to prevent peanut allergies altogether.
Dissolve ¼ teaspoon salt in one cup of warm or room temperature water for flushing out allergens and mucus and for adding moisture to the sinuses. Dissolve ½ teaspoon salt in one cup of warm or room temperature water to draw fluid and inflammation out of the nasal membrane. This will help relieve stuffiness.
Higher hygiene levels in modern society may cause the immune system to develop inappropriate reactions to some food proteins, and the fact that peanut oil is used in a lot of infant skin creams may prime the immune system early on. Roasting peanuts also seems to increase the concentration of some of the allergens.
Do not take more than 6 doses in 24 hours. Use only as directed. 2 to 4 chewable tablets (25 mg to 50 mg) every 4 to 6 hours or as directed by a doctor. 1 to 2 chewable tablets (12.5 mg to 25 mg) every 4 to 6 hours or as directed by a doctor.
Should you take Benadryl before or after an allergic reaction?
Instead, we should be taking the medicine before we have symptoms. Call it allergy pretreatment. “We always tell people to start taking medicine before the allergy season begins,” says Jonathan A. Bernstein MD, an allergist and professor of clinical medicine at the University of Cincinnati.
Anaphylaxis symptoms usually occur within minutes of exposure to an allergen. Sometimes, however, anaphylaxis can occur a half-hour or longer after exposure. In rare cases, anaphylaxis may be delayed for hours.
Antihistamines are recommended for treatment of mild and moderate allergic reactions, including allergic rhinitis (hay fever), but have no role in treating or preventing respiratory and cardiovascular symptoms of anaphylaxis.
Studies show that an estimated 20–25% of children experiencing a peanut allergy will outgrow it. Of those that outgrow their allergy, 80% do so by the age of eight. While this data offers relief to many parents, it still means a large proportion of individuals will need to manage their condition.
An allergic response to peanuts usually occurs within minutes after exposure. Peanut allergy signs and symptoms can include: Skin reactions, such as hives, redness or swelling. Itching or tingling in or around the mouth and throat.
Symptoms of peanut allergy can range from mild to severe. If you have a mild reaction, you may get: A stomach ache. A runny nose.
When an individual with IgE mediated food allergy accidentally eats a food that contains their offending allergen (e.g. peanut), a reaction will usually happen within minutes, but can take up to 2 hours. Anaphylaxis often begins within minutes after a person eats a problem food.
There is no substitute for epinephrine, which is the only first-line treatment for anaphylaxis. Neither antihistamines nor glucocorticoids work as quickly as epinephrine, and neither can effectively treat the severe symptoms associated with anaphylaxis.
If you believe someone near you is suffering from anaphylactic shock, call 911. Do this first if the person doesn't have an EpiPen. Perform CPR. If the person suffering the allergic reaction does not have an EpiPen and loses consciousness, you may have to perform CPR.
Q: What do you do if someone goes into anaphylactic shock without an EpiPen? A: Make sure that you've called 911. If antihistamines are on-hand, these can be administered and may provide some relief, but antihistamines are never a suitable medication for fully treating anaphylactic shock.
What is the difference between allergic reaction and anaphylaxis?
Allergic reactions are common in children. Most reactions are mild. A severe allergic reaction (i.e. anaphylaxis) involves a person's breathing and/or circulation. Anaphylaxis is the most severe form of an allergic reaction and is life threatening.
- Call 911 immediately.
- See if they have an epinephrine (adrenaline) auto-injector (EpiPen) and help them, if needed.
- Try to keep the person calm.
- Help the person lie on their back.
- Raise their feet about 12 inches and cover them with a blanket.
Diphenhydramine is an antihistamine used to relieve symptoms of allergy, hay fever, and the common cold. These symptoms include rash, itching, watery eyes, itchy eyes/nose/throat, cough, runny nose, and sneezing. It is also used to prevent and treat nausea, vomiting and dizziness caused by motion sickness.
Epinephrine (EpiPen, EpiPen Jr, Adrenaclick, Auvi-Q)
Epinephrine is the drug of choice for the treatment of anaphylaxis.

Between 1 percent and 15 percent of the population of the United States can be considered at risk for having an anaphylactic reaction when exposed to one or more allergens. Of those people who experience anaphylaxis, up to 1 percent die.
- feeling lightheaded or faint.
- breathing difficulties – such as fast, shallow breathing.
- wheezing.
- a fast heartbeat.
- clammy skin.
- confusion and anxiety.
- collapsing or losing consciousness.
If you do not receive the proper treatment, anaphylaxis can turn deadly in less than 15 minutes. The hospital staff will want to monitor you closely. They may give you another injection. In the case of severe reactions, one injection is sometimes not enough.
Allergies to food, insect stings, medications and latex are most frequently associated with anaphylaxis. A second anaphylactic reaction, known as a biphasic reaction, can occur as long as 12 hours after the initial reaction.
"If you have a simple rash, and you're itching, you can probably go to urgent care. But if you have a rash and vomiting, you should go to the ER." An anaphylactic allergic reaction can be life-threatening and requires immediate medical treatment.
Can you survive anaphylaxis without treatment?
Anaphylaxis requires immediate medical treatment, including an injection of epinephrine and a trip to a hospital emergency room. If it isn't treated properly, anaphylaxis can be fatal.
Skin rashes, itching or hives. Swelling of the lips, tongue or throat. Shortness of breath, trouble breathing or wheezing (whistling sound during breathing) Dizziness and/or fainting.
Keeping epinephrine on hand at all times should be just part of your action plan. It's also a good idea to carry an over-the-counter (OTC) antihistamine as this can help treat mild allergy symptoms.
“While the use of antihistamines might help some allergic symptoms such as rash or itching, those medications will not prevent death from anaphylaxis,” Dr.
Antihistamines DO NOT stop the progression of an anaphylaxis. Antihistamines only help to decrease itching and reduce mild/moderate swelling of the face, lips and eyes.
Diphenhydramine has been commonly used as the antihistamine of choice for acute food allergic reactions given its prompt onset of action (15–60 minutes)1 and ready availability, though epinephrine is still the first-line therapy for anaphylaxis.
What to Expect. Benadryl is absorbed quickly in the body. You'll probably notice the effects within about 20 to 30 minutes. The medicine should continue to work for about four to six hours.
Today the U.S. Food and Drug Administration approved Palforzia [Peanut (Arachis hypogaea) Allergen Powder-dnfp] to mitigate allergic reactions, including anaphylaxis, that may occur with accidental exposure to peanuts.
Sometimes people outgrow some food allergies over time (like milk, egg, soy, and wheat allergies), but peanut and tree nut allergies are lifelong in many people.
Anaphylaxis symptoms usually occur within minutes of exposure to an allergen. Sometimes, however, anaphylaxis can occur a half-hour or longer after exposure. In rare cases, anaphylaxis may be delayed for hours.
Can anaphylaxis occur 12 hours later?
Allergies to food, insect stings, medications and latex are most frequently associated with anaphylaxis. A second anaphylactic reaction, known as a biphasic reaction, can occur as long as 12 hours after the initial reaction.
Interactions between your drugs
No interactions were found between Benadryl and EpiPen. However, this does not necessarily mean no interactions exist. Always consult your healthcare provider.
There is no substitute for epinephrine, which is the only first-line treatment for anaphylaxis. Neither antihistamines nor glucocorticoids work as quickly as epinephrine, and neither can effectively treat the severe symptoms associated with anaphylaxis.
The ER medical personnel will monitor the patient and provide additional medications ensuring the allergic symptoms are under control. Many allergic reactions can be managed with the right medical care. However, for the more severe ones you need to visit the ER especially if you suspect anaphylaxis.
