No.: Caffeine has been shown to help with bronchodilation (relaxation of the small tubes in your lungs) which helps with air movement. Asthmatics have noted slight symptomatic benefit after ingesting caffeine. This may help your "allergies" depending on what those symptoms may be. Your dose of caffeine would also have to be taken into consideration.

Allergies (Definition)

Allergies occur when your immune system is triggered by envirionmental factors it should ignore--for example, pollen in the air, or dander on a cat or dog--and creates cells to fight against them. An allergic reaction typically causes itching, congestion, or drainage, and ...Read more

What are the symptoms of a caffeine allergy?

What are the symptoms of a caffeine allergy?

Not "allergy": Caffeine acts more like a chemical and not l ike an allergen, it does not cause immune reactions, but as a chemical has numerous effects on the cardiac and nervous systems such as jitteriness, nervousness, increased intestinal motility, and so on.

Very unlikely.: I hesitate to say impossible, but caffeine allergy is very highly unlikely. Allergy is typically to a protein. There are some exceptions, however I do not know of a case of proven caffeine allergy.

What is the definition or description of: Caffeine allergy?

Extremely rare: There are 2 case reports of caffeine allergy published and both are from Spain. One patient had hives and the other had anaphylaxis. There is a higher likelihood of workers in the coffee bean industry developing work related asthma from the inhaling the dust of coffee beans before they are roasted.

If a person has an allergy towards coffee is it normally the coffee itself or the caffeine?

If a person has an allergy towards coffee is it normally the coffee itself or the caffeine?

Unlikely: Coffee allergy is rare if ever existed. You will need to tell us the symptoms from drinking coffee. There had been reports that occasionally coffee beans were contaminated with castor bean which can cause a contact allergy. Caffeine is not an allergen.

How would I go about confirming a caffeine allergy/ intolerance? When I consume caffeine I have what seems to be an anaphylactic reaction.

How would I go about confirming a caffeine allergy/ intolerance? When I consume caffeine I have what seems to be an anaphylactic reaction.

Distinctly Unusual: Caffeine allergy is unusual but has been reported in the literature. After speaking to your allergist and clarifying your history, there are several options that could be explored. Skin testing could be done but there is no standardized skin test reagents for caffeine thus the results must be interpreted with care. Oral challenges could be considered but only with your physicians supervision.

I have anxiety. Is it possible to have an allergy to caffeine? If I only have 1 cup of coffee a day I've noticed an increase in shakiness and headrush

I have anxiety. Is it possible to have an allergy to caffeine? If I only have 1 cup of coffee a day I've noticed an increase in shakiness and headrush

Sensitivity: Is likely a better term for it. And it is not an "essential nutrient" (despite what some folks may tell you), so if it causes you distress then it is best avoided completely. Discuss in more detail with your Dr at next visit.

Why after a cup of tea I felt cold flu and restless accompany by dizziness. Am I allergy to caffeine or tea leave?

Perhaps the caffeine: Is causing you anxiety. Some people experience this and it's not a true allergy, but the response of being overstimulated from the Caffeine. Try and cut back or go decaf.

Allergy, intolerance, or viral? I get vertigo when I eat nuts, chocolate and caffeine, and basic dizziness from other foods. Started after shingles.

Allergy, intolerance, or viral? I get vertigo when I eat nuts, chocolate and caffeine, and basic dizziness from other foods. Started after shingles.

Inner ear issues?: If the nerves related to your inner ear get swollen they could easily result in feelings of vertigo/dizziness. Perhaps the foods are causing the nerves to swell? Post nasal drip and eustachian tube dysfunction might do it. Chinese medicine or cranial osteopathy might help. Diazepam is a western medication that would effectively treat symptoms.

Is it more likely to have an allergy to caffeine, or stimulants in general? Skin rashes appear on lower face and upper chest. Testing for this?

Is it more likely to have an allergy to caffeine, or stimulants in general? Skin rashes appear on lower face and upper chest. Testing for this?

Quite rare: I don' recall ever seeing someone allergic to caffeine. As each stimualnt drug is quite different chemically from others an allergy to all stimulants is even less likely. There is also no skin or blood test for such an allergy but that doesn't mean it can't be done. A double-blind challenge is the method used to establish a relationship between a cause & an effect. Your local allergist can help.

I took an allergy pill and got sleepy. I drank caffeine to wake up and I just used chew tabacco. My heart had a pinching feeling and I'm shaking bad!?

Substance&med abuse: You shouldn't do what you just did. All of what you just took cause your heart to beat fast or even arrhythmia or irregular heart beats. If you see any signs of dizziness, light headedness, you should seek medical attention by going to the er immediately. Those are signs that your brain does not get perfused sufficiently due to arrhythmia.

Whend I drink coffee I get visibly shaky, By Gerd is awful, my stomach gets sharp pains and I get so anxious, Is it caffeine? An allergy?

Intolerance: Intolerance NOT allergy. The symptoms you describe are all classic signs of an intolerance to caffeine. It seems like you are more sensitive than most to its effects. Coffee can also aggravate GERD. To limit these symptoms either avoid coffee entirely or only drink small amounts. This is not a true allergy to caffeine, is not life-threatening, and does not require an epinephrine injector.

When I drink caffeine, even weak tea, I get massive headaches/migranes and abdominal cramps and need the loo a lot. Is this an allergy or an intollerce or something else? And can you recomend alternatives for quick pick-me-ups?

When I drink caffeine, even weak tea, I get massive headaches/migranes and abdominal cramps and need the loo a lot. Is this an allergy or an intollerce or something else? And can you recomend alternatives for quick pick-me-ups?

Caffeine side effect: Those symptoms are side effects of the world's most-consumed stimulant; avoid it if intolerant to it. In our fast-paced society, there's a tendency to want a push-button quick-fix; I've had patients request a med to wake up, one to sleep, one to calm down, one to feel energetic, all at same appointment. Natural pick-me-up: exercise (my wife loves running in place for about 15 to 30 seconds).

Avoid Caffeine & Tea: It appears from your symptoms that you are very intolerant of tea itself at least and perhaps also caffeine. Caffeine is one of the biggest risk factors and causes of migraines and their recurrence. Avoidance is best option. As far as pick me ups try hydrating with more water as this always helps and get plenty of sleep. Perhaps a little chocolate if caffeine isn't the cause? ;-) be careful!

Undetermined: At federal level - marijuana is still illegal. At state level - legalized in some, not so in others. Therefore, physicians at this time are legally bound to not recommend marijuana for routine use. More importantly, marijuana has not been studied for treatment of chronic pain and we do not know if it truly helps. Jury is still Out there..
