Can taking an antihistamine stop itching?

Yes. Usually a wheal response, also known as swelling is caused by your body producing a histamine. What this does is allow fluid to pass from small blood capillaries into the surrounding tissue. This allows the fluid to surround or envelope an irritant such as a scratch or insect bite. The final result is an irritating itch.

By taking an antihistamine, you reduce the amount of histamine your body produces resulting in the lessening of the itch. This can be taken orally such as benadryl tablets or as a topical ointment (outside the body applied to the affected area). Please take the time to ask a doctor or nurse how this may have an adverse effect upon you as some people who take antihistamines get a energy burst while others feel sedated or sleepy.

Do chihuahuas affect allergies or asthma?

Yes! They do! It is a miricle!

Yes. Not in the way you think. If you are allergic to dogs, getting a chihuahua will make your allergies and your ASTHMA WORSE. This is a myth that they take away asthma. Be sure to have yourself tested for allergies first. If you are not allergic to dog dander, then you will be fine and have a cute active pet.

Can one be allergic to the tomato seeds and not the tomato itself?

My Gradfather was. He could eat the flesh of the tomato but not the seeds. He was also alergic to the seeds on strawberries. I'm sorry that I do not have more of a technical answer.

How can you tell what allergy you have?

Blood tests can be done to look for elevated white blood cell counts, level of particular antibodies, or for reactions with allergen extracts. Blood tests are not 100% reliable and, to get good results, must be done by highly trained lab technicians. Some doctors use these tests, while others prefer not to. The patient will need to have blood drawn for this, which may be a drawback for testing children.

"Scratch" test involves scratching the skin, then dropping liquid allergen on the scratch. It's done on the arm or (for very small children) the back. It seems to hurt a little, but may be scary to little ones. Each slate has up to 6 tests, plus positive (histamine) and negative controls. Bumps/weals for a reaction appear immediately or several minutes later. The patient must remain in the office in case of severe reaction (rare).

A positive reaction is reliable, but a negative reaction may not be; that is, you may be allergic but not react. Skin tests are more reliable for airborne allergies than for foods.

Elimination diets are the only guaranteed way to determine food allergies. The patient goes on a *very* restricted diet, composed only of foods that rarely cause allergy problems. A new food is added each week. If the patient does not have any allergic symptoms to the new food during that week, then it is not considered an allergen. A new food can be added the next week. If the patient has a reaction to the food, the food is considered an allergen and removed from the diet. The patient then goes back to the previous diet until all symptoms are gone for three days; then a new food can be added. This is a very slow way to build up much of a varied diet, but it is certain. In adding foods, you must be careful that it is only one food that is being added. This means no processed foods (may have additives), no pre-packaged foods (may have additives), no seasonings (except salt), etc. This can be very difficult to follow if you eat out for any meals. Generally safe, non-allergenic foods usually include apricots, peaches, pears, beets, sweet potato, rice, distilled or spring water, cane sugar, salt, tapioca, olive oil, lamb and chicken. (Not very exciting..) Your doctor may give a different list, based on your personal situation. It is fairly easy to put a young baby on an elimination diet, but it gets harder as the child gets older. For very young children, this should only be done under a doctor's supervision (unless the child is exclusively breastfed) to ensure a balanced diet.

If the original allergic reaction was moderate or worse, you must challenge test when adding a suspected new food. That is, you start with a pea-sized piece. If no reaction, on day 2 try a 3-pea-sized piece. No reaction, day 3 try a 9-pea-sized piece. Discuss this with your doctor. ALWAYS get instructions beforehand (and medicine, if necessary) on what to do for a severe reaction. If the original reaction was severe, your doctor will want to do this at his office or at the hospital.

How do you take down swelling in the face?

It depends on where the swelling is. If it's on the skin put ice on it for like 30 minutes. If swelling has not gone down in 2 days go to the doctor.

How do you apply salt water for skin allergy?

Rinse off the salt water first thing. If the rash itches, take an antihistamine (ie benadryl). You may be able to calm the rash with a cool low fat milk compress (helps the rash heal) or by using a non-fragrant cream like aloe or diaper rash cream.

Can your breastfed baby have an allergic reaction from something you ate?

YES!!!!

Although it's extremely rare! In case a baby shows an allergic reaction to breast mik, it is more likely that it reacts to foods which the mother eats, as they pass through the breast milk into the baby's digestive system. On many sites (especially on forums) you read that "babies are never allergic to breast milk". This is NOT true! It is very rare though. There is a genetic disease called methylmalonic acidaemia (MMA). This condition means that the baby is unable to breakdown protein and thus the protein in the milk is poisoning the whole body. This is a very serious situation and can eventually result in the babies death, if the breastfeeding continues (see http://www.itv.com/Lifestyle/ThisMorning/Health/AllergictoBreastMilk123/default.html). More info here: http://children-allergy.com/is-your-baby-allergic-to-your-breastmilk

In very rare cases a mother's immune system can create antibodies (transmitted through the breast milk) that can be harmful to her baby. In that rare case, the baby cannot continue breastfeeding and the mother will be offered a shot by her medical doctor to prevent this kind of immune response in future childbearing. Again that's very rare, and the number one symptom of that is SEVERE jaundice. If you suspect that your child is suffering from food-allergy you should consult with your pediatrician. Unfortunately many pediatricians are reluctant to conclude that a child is allergic to food. Your may have to fight your corner. Also many are hesitant to tell a mother to drop things from her diet, because they're concerned about her nutrition. Stand your ground and if your pediatrician refuses to listen to your concerns, you can ask to be referred to an allergist.

How is histamine related to allergies?

An allergy is a hypersensitivity to an environmental antigen (allergen). If a person has a hypersensitivity to an antigen they will have a patholigic (disease) response when exposed to that antigen. When the hypersensitive individual is initially exposed to the antigen, they will produce allergen specific antibodies, primarily immunoglobulin E (IgE), that will during subsequent exposures bond with membrane proteins on the mast cell membrane. This bonding allows degranulation (the release of stored chemicals) of the mast cell. Mast cells manufacture and store chemicals, including histamine, that are responsible for the affects of inflamation.

Can you take clindamycin if allergic to neomycin?

Yes. Clindamycin is not a penicillin-like antibiotic, so it may be used if allergic to penicillin. However, this does not mean you cannot be allergic to this drug also.

What is chronic urticaria and how long does it last?

It really depends. I've had mine since I was fourteen. Many people have different time spans in which cold urticaria occurs. Mine has been relatively mild but is getting worse with age. I carry an epinephrine injector (epi-pen) and take Xyzol for the reactions. It is not an easy condition to live with and is usually pretty embarrassing, to tell you the truth. It's not very fun having an extremely bad break out of hives all over your legs because you stood in the ocean. This incident happened a week before I was diagnosed so I had no medication and had to take benedryl for the reaction. Anyone that knows me never gives me benedryl because it gives me symptoms like I'm on drugs. Not a great thing when you are on a trip with your youth group.lol. I not only have cold urticaria but I also have CU Aka exercise urticaria. Where I live, It is often cold. And being in a military organization, I have to do a lot of running in the cold. Very embarrassing to be the only girl out of 30 guys and have a completely swollen and blotchy face and hands. Just take medication BEFORE doing anything even remotely cold. And unlike me, DON'T FORGET YOUR MEDICATION. Big mistake on my part.

Define anaphylactic shock?

AnswerAnaphylactic reactions are general, dramatic reactions that can result in collapse and possibly death. It is caused by a sudden release of histamines and other chemicals that overwhelm the body. The onset is usually quite rapid and symptoms occur within minutes. Death can potentially occur immediately or within two hours.

The first sign may be tightness of throat, swelling and redness of the skin or may be a non-visible internal reaction such as swelling of the airway, a drop in blood pressure, shock, or nausea. The allergic person may also have a feeling of great anxiety.

Immediate action is needed. Persons who know they are prone to these reactions (allergies to peanuts, shellfish, and insect stings can be of this type), should consult with their doctor about a small emergency kit to carry with them. This kit will usually have antihistamines and Epinephrine [The most common Epinephrine is the UK Epipen]. For this type of reaction, call for medical help [ambulance] immediately. Minutes are vital.

Standard treatments used to control the reaction are epinephrine, oxygen, and intravenous fluids. Antihistamines and corticosteroids can also be used. The person needs to be under medical supervision until the reaction is under control.

In other words, when you have an anaphylactic reaction(as a sufferer of one as well) it is when several reactions happens such as hives, wheezing rashes and suffercation. The person having the anaphylactic reaction will be in great pain but should be carrying an Eppipen which is a spring loaded shot of adrenaline.

Is there gluten in potato?

No, there is no gluten in potato. However, for people strictly avoiding gluten, for processed foods you may need to check for cross-contamination with gluten. Traces can creep in during the manufacturing process, particularly on shared manufacturing lines. Also note that some french fries are made with a wheat (gluten-containing) coating. Other fried products may be cooked in oil that is used for gluten-containing products.

Nausea dizziness stomach pain?

Well, for starters, if you have a problem with the heat, than you can have some sort of disorder.

It's also common among young people so, if I were you just look up your symptoms on google.

What is the difference in wheat free and gluten free?

Vital Wheat Gluten is a wheat flour protein material that has been seperated from the starch then dried rapidly with a minimum amount of heat in order to preserve its vitality. ( functional characteristics including extensibility.) Used o improve dough strength at levels from 1 to 4 % for most yeast - raised products to as much as 10 % in high fiber breads. ( percent based on flour weight.) Vital Wheat Gluten contains a minimum of 75 % protein, dry weight basis.

Gluten - A compbination of two groups of proteins, gliadin and glutenin. These two compounds interact when wheat flour is mixed with water, forming rubber-like strands that provide bread doughs with elasticity and extensibility.

Both Definations are based upon the American Institute of Baking- Science of Baking- Correspondence course - Ingredient Technology Glossary.

- from an experienced baker. Gluten is naturally occuring in wheat. its rubbery strands that occur when gliadin and glutenin are hydrated and mixed riggerously. It is what gives dough its strength. Sometimes, when flour doesnt contain enough protein... ie Gluten (gliadin, and glutenin) the baker will add VITAL WHEAT GLUTEN give the dough additional strength. Gluten is natural in wheat... vital wheat gluten is a supplimental additive. It is more potent, and more pure than the gluten found in wheat.

Is it a cold the flu or allergies?

The flu (full name influenza) is caused by a virus. You can differentiate between an allergic reaction like hay fever and infection with the flu by watching for fever, hot and cold chills and muscle aches - all of these are common with the flu but uncommon in an allergic reaction.
