Will Benadryl help a food allergic reaction?
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.
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.
There is very little data comparing the oral forms of Zyrtec and Benadryl. One study compared the two medications for food allergies. The study concluded that Zyrtec was similar to Benadryl's effectiveness and took the same amount of time to start working. Zyrtec also had a longer duration of action (lasted longer).
There are two main types of medication that can be used to relieve the symptoms of an allergic reaction to foods: antihistamines – used to treat mild to moderate allergic reaction. adrenaline – used to treat severe allergic reactions (anaphylaxis)
- Epinephrine (for example, EpiPen® or Auvi-Q), a lifesaving emergency medication that immediately begins reversing symptoms of anaphylaxis.
- Antihistamines, medications that reduce itching or congestion.
- Corticosteroids to reduce swelling if you have a severe allergic reaction.
"While your body is purging the allergen food from it is system, the best thing you can do is drink plenty of fluids," Zeitlin says. Water is always a good idea, but you can also sip on low calorie sports drinks to replenish the electrolytes you're likely losing, Zeitlin says.
For mild allergy symptoms in adults and children ages 12 years and older, 25 mg to 50 mg of Benadryl is recommended every 4 to 6 hours. The most you should take in a 24-hour period is 300 mg. For children ages 6 to 11 years, the recommended dose is 12.5 mg to 25 mg every 4 to 6 hours as needed.
Allergy to foods is commonly reversible. Symptoms often clear following 3-6 months of avoidance and nutritional therapy.
With or without treatment, the itching will go away in 1 to 2 hours. The mouth swelling will also go away quickly.

How much antihistamine should I take for food allergy?
Adults and teenagers—25 to 50 milligrams (mg) every four to six hours as needed. Children 6 to 12 years of age—12.5 to 25 mg every four to six hours. Children 4 to 6 years of age—6.25 to 12.5 mg every four to six hours. Children and infants up to 4 years of age—Use is not recommended .
An antihistamine pill, such as diphenhydramine (Benadryl), isn't enough to treat anaphylaxis. These medications can help relieve allergy symptoms, but they work too slowly in a severe reaction.
Many people with food allergies wonder whether their condition is permanent. There is no definitive answer. Allergies to milk, eggs, wheat and soy may disappear over time, while allergies to peanuts, tree nuts, fish and shellfish tend to be lifelong.
1 to 2 chewable tablets (12.5 mg to 25 mg) every 4 to 6 hours or as directed by a doctor. Do not use unless directed by a doctor. Do not use. Do not take more than 6 doses in 24 hours.
Benadryl is recommended only as a short-term treatment for people with symptoms of allergies or other conditions that the drug treats. If you take Benadryl long term, you may develop long-term side effects of the medication. Which side effects you experience can determine how long your side effects last.
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.
While there's ongoing research to find better treatments to reduce food allergy symptoms and prevent allergy attacks, there isn't any proven treatment that can prevent or completely relieve symptoms. One treatment currently being studied as a treatment for food allergy is oral immunotherapy.
Maybe you've moved and are being exposed to different allergens, which trigger your immune system. A viral or bacterial infection could also flip that switch. Hormones can be a catalyst, too, especially in women. It's not uncommon to develop food allergies during puberty, pregnancy or menopause.
For example, if you ingest something that causes your body to produce an allergic reaction, water can essentially help dilute the irritant and again, assist in regulating an appropriate histamine response. It's important to note again however that water can't prevent or interrupt serious allergic reactions.

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.
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. An important aspect of allergy and anaphylaxis management is prevention by avoiding the cause.
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.
With or without treatment, the itching will go away in 1 to 2 hours. The mouth swelling will also go away quickly.
However, most people recover quickly without treatment, and symptoms are usually gone within 12 to 24 hours. Home treatment for mild to moderate symptoms includes taking over-the-counter antihistamines such as diphenhydramine (Benadryl®) and drinking fluids to prevent dehydration.
Your GP may suggest taking antihistamines to reduce swelling when it occurs. Antihistamines work by blocking the effects of histamine, one of the chemicals responsible for the swelling.
Stomach acid will destroy the raw food allergens so the symptoms usually stop when you swallow the food. The allergy rarely progresses to a systemic reaction. Cooking the food will also destroy the allergen protein so canned and cooked fruits or vegetables rarely cause symptoms.
How does the ER treat food poisoning?
Different treatments include: Rehydration with intravenous fluids and electrolytes for severe dehydration. Monitoring for complications such as kidney or nerve damage. Antibiotics for severe food poisoning from bacteria, such as E.
Gradually begin to eat bland, low-fat, easy-to-digest foods, such as soda crackers, toast, gelatin, bananas and rice. Stop eating if you feel sick to your stomach again. Avoid certain foods and substances until you're feeling better.
In some cases, adults can take over-the-counter medicines such as loperamide link (Imodium) and bismuth subsalicylate link (Pepto-Bismol, Kaopectate) to treat diarrhea caused by food poisoning.
