Why do some people say they aren't allergic to poison ivy/oak/sumac? Are some people immune or just lucky?
Poison Ivy: Some people appear to be immune, others become immune. However, you can gain or lose immunity, so to assume you can't get it if you never have before is foolish. People change as they age. I would never assume that i was immune at any time no matter what my past experience was. ...Read more

All the same: Good question and many people ask me this. As far as the antigen that causes allergy goes all dogs are the same as remarkable as that may seem. This allergen is especially found in dog saliva and can spread from there. Dogs that salivate , lick or shed more are perhaps more likely to disperse the allergen. ...Read more
No one knows...: I hear ya. Allergies are common and increasing in frequency, but in truth still only occur in a minority of people. A very loud minority, given the complaints of pollen allergy in the spring. But it's not just environmental allergies; the prevalence of other allergic conditions are on the rise, too - notably food allergy. On the flip side, only those with strong immune systems get allergies! ...Read more
Not really: Bees generally don't make pollen allergies worse, but people can be allergic to bee stings. Bee sting allergy is due to an allergy to the insect venom injected during a sting. The pollens that bees transport while gathering nectar from flowers are from predominantly insect-pollinated plants, and these pollens don't cause allergy symptoms. Wind pollinated plants generally cause allergy symptoms. ...Read more
My son has seasonal outdoor allergies. Nothing too severe, but claritin (loratadine) doesn't seem to be doing much today.can i give allegra too?
Depends: Usually taking Claritin (loratadine) And Allegra in one day will not hurt but it depends on age of son and also depends on cause of symptoms. I would not give both in one day if under 6 years old. Also you might want to bring him to pediatrician or allergist to make sure he truly has a diagnosis of allergies and not something else! ...Read more
Saw many ents (sang opera). Chronic post nasal drip shown to have no cause, just an idiosyncrasy. Always 'saline/occasional afrin'. Anything better?

May not be: People with the form of apple allergy that causes mouth and throat itching, so called oral allergy, or pollen fruit oral allergy syndrome, is usually a cross reactivity with pollen allergies, and is usually due to a heat labile protein. Heating destroys the protein's effect. ...Read moreSee 2 more doctor answers
No: Generally no. If you are receiving allergy shots, it is important to have the correct tree pollen that is responsible in the shot, but otherwise the basic principles are the same. Knowing which tree pollens are responsible for your allergies can help plan desensitization (allergy shots) and might help you predict which seasons will be difficult for you. ...Read moreSee 1 more doctor answer
Yes: The lungs require humidified air to function at their best. Wood burning furnaces are both very dry heat and can sometimes produce irritating smoke or fumes that irritate the lung. Some are not as sensitive to this effect than others and some furnaces are better designed & produce less irritation than others. Many electrical furnaces have an attached humidifier to help with this issue. ...Read moreSee 1 more doctor answer
Some people aren't: Because some people are not allergic to it. Allergies depend on the response of several factors of the individual immune system. For different reasons, some people develop an allergy to something and others do not. Over time with more exposure, someone previously without a problem can develop it. Once there, it almost always remains though. ...Read more
Allergies: Allegra (fexofenadine) and other antihistamines work up to a certain point and do not cure allergies, just control the symptoms. Some patients need more than one medication to control their allergies and some no longer respond to meds. Shots from a board certified allergist can provide you long term relief and decrease your dependence on medications and can potentially cure you. ...Read more
Peanut allergy: It is thought to be related to environment and genes. A recent high profile study (LEAP study), suggests that delayed introduction of peanut to the diet, might contribute to the increase in peanut allergy. Age seems to be an important determinant. New treatments are under clinical trial evaluation. ...Read more
Good question: We still don't know for sure. There is definitely a strong hereditary component. When our immune surveillance encounters a potential invader it triages the type of response like branches of the military. But in this case they mistakenly sent the air force instead of the police. Co-factors are involved like diesel exhaust. Early antigen exposure seems to be protective. See Hygeine Hypothesis ...Read more
