Urticaria is a type of skin rash caused by an allergic reaction that can last from a few minutes to a few days and develops for a wide variety of allergens. If you are predisposed to this disorder, try to avoid it by learning to prevent it.

Learn how  to prevent urticaria

1) Avoid known allergens.
This is the first and simplest approach to prevent hives; this means staying away from situations where you could export to allergy-causing factors or learn to adapt to the inevitable ones.

For example, if you are allergic to some food that causes hives, you should avoid eating it; when you go to a restaurant or someone’s home, say you suffer from some food allergy and ask which dishes do not contain that specific ingredient.
If you are subject to solar urticaria, you must be cautious when you go out in the open; wearing a hat and long-sleeved shirts, in addition to applying the protective cream. Avoid staying too long exposed to direct sunlight and try to stay in the shade.
If you suffer from a pressure urticaria, do not wear excessively tight clothing.
To prevent cold weather, do not swim in cold water and if you do, make sure you are not alone. Put a scarf around your nose and head when you walk outdoors in winter; dressed in warm clothing and in layers when the weather is hostile.
When you are in a situation where you can not avoid skin rashes, you can learn how to handle them.

2) Subject to allergy tests.
It is possible to identify some allergens responsible for the disorder through a series of skin tests. There are basically two main types of tests: some substances are applied to the newly scratched skin or injected in minimal doses under the epidermis; they are not very painful procedures, but they can create a bit of discomfort, especially if you react to the substance.
Most positive reactions develop within a short time, usually within 20 to 30 minutes; any late replies may occur within 24-48 hours.
For small children and infants, a blood sample is usually taken to test the sample.
We also proceed with the withdrawal for people who run the risk of anaphylaxis, who are taking certain drugs or who suffer from some serious skin disorder, such as eczema or psoriasis, in order to avoid serious skin reactions.
Skin tests can be repeated for a wide variety of substances, but keep in mind that a specific allergen that causes a reaction may not be included in the screening panel; it is, therefore, possible that even after performing the test you do not yet know what element you need to avoid.

3) Keep a diary of skin rashes.
If you do not detect the substances you are allergic to, you can keep a diary to narrow down the possibilities. Take note of all the little things that can cause hives, even if you do not know for sure if they are really responsible. In particular, pay attention if the reactions occur in similar circumstances or if you notice them only when you expose yourself to specific situations.
Write down what you eat, the medicines you take and the environmental allergens you are exposed to; among these considers the hair of animals, dust and plants.
Keep track of any sudden changes in temperature or physical injury, such as scratches or abrasions that could cause hives.
Even the vibrations can provoke this disturbance, so take note of the vibrating objects that touch, like loudspeakers with very intense bass, the mower or the pneumatic hammer.

Treat the Urticaria

4) Soak up the suffering areas.
When the urticaria is mild, the most common and effective way to treat it is to soak the skin in warm water or apply a fresh compress; in any case, you should always avoid rubbing or scratching the outlets, because you could aggravate the situation.
Put a cloth in lukewarm water and place it on the affected areas. If the urticaria has hit the whole body, put yourself in the bathtub full of warm water and soak for 10-20 minutes.
Wet a cloth in cold water or place one wet in the refrigerator before applying it to the itchy and painful areas.

5) Take antihistamines.
They are often recommended in case of moderate urticaria since they are specific to block the histamines responsible for the rash. They are available in pharmacies for free sale or on prescription; among the main drugs suitable for this purpose there are:
Sedative antihistamines such as brompheniramine, chloramine (Trimeton) and diphenhydramine (Benadryl);
Non-sedating antihistamines, such as cetirizine (Zyrtec), clemastine (Tavegil), fexofenadine (Telfast) and loratadine (Claritin);
Bench-top corticosteroids in nasal sprays, such as triamcinolone acetonide (Kenacort) and prescription ones such as prednisone, prednisolone, hydrocortisone and methylprednisolone;
Mast cell stabilizers, such as sodium cromoglycate;
Leukotriene inhibitors, such as montelukast (Singulair);
Immunomodulatory substances for topical use, such as tacrolimus (Protopic) and pimecrolimus (Elidel).

6) Test of plants and supplements with anti-inflammatory properties.
There are several herbs and food supplements that have these anti-inflammatory characteristics and which you can take every day to prevent outbreaks of hives; be sure to follow the instructions on the package regarding the dosage and do not give these remedies to children who are less than five years old, without the favorable opinion of the pediatrician.
Rutin is a natural bioflavonoid present in citrus fruits and buckwheat, can help reduce inflammation and swelling by limiting the leakage of blood from the blood vessels; always comply with the manufacturer’s instructions regarding the dosage.
Also, quercetin, which is produced in the body starting from rutin, is able to actively reduce inflammation and swelling; it has also been found that it is much more effective than sodium cromoglycate in blocking the release of histamine. Also, in this case, follow the instructions on the package to assume the correct quantity.
Bromelain is an enzyme present in pineapple and helps reduce swelling due to urticaria; you can take it as a supplement by following the manufacturer’s instructions for how to use it.
Coleus forskohlii is an ancient plant used in Ayurvedic medicine, has been shown to reduce the histamines and leukotrienes of mast cells; remember to respect the methods of use indicated on the package.
Nettle is traditionally used to treat hives; its scientific name is “Urtica dioica” and the term urticaria derives from this plant. You can prepare a herbal tea by infusing a teaspoon of this dried herb in 250 ml of boiling water and letting it cool; you can drink all the cups you want, usually three or four a day.

7) Take epinephrine if you have an anaphylactic shock caused by a severe form of hives.
It is a dangerous allergic reaction, sometimes even fatal, which can develop concomitantly with urticaria; in rare cases, the rash may also cause swelling in the throat and trigger an emergency situation that requires the intake of this active ingredient. Epinephrine can be administered through EpiPen to individuals who have a severe allergy to a particular substance and who need this drug to avoid anaphylactic shock.
Among the symptoms of anaphylaxis you can see:
Skin rashes that also include hives and can cause itching and —
– reddened or pale skin;
-A sense of warmth;
– The sensation of a knot in the throat;
– Dyspnoea or other breathing difficulties;
– Swelling of tongue or throat;
– Tachycardia and accelerated pulse;
– Nausea, vomiting or diarrhoea;
– Vertigo or fainting.
If you or someone you know is experiencing some of these symptoms, seek medical attention immediately.
If EpiPen was prescribed for your child or another loved one, make sure you know where it is and how to use it; Ask your doctor or pharmacist to teach you how and when to use it.

8) Talk to your doctor regarding chronic urticaria.
If it becomes a lasting or chronic problem, you should ask the family doctor to send you to a specialist. An allergist can perform tests to determine, if possible, the causes of your allergic reactions.
Allergy tests cover food, plants, chemicals, insects and their bites.

To know the Urticaria

9) Identify the disorder.
It consists in the development of swollen, reddened and itchy skins on the skin that become white at the pressure. In most cases, it is roundish config, although the different lesions sometimes seem to merge together and form a large one with irregular edges.
Hives can develop on any area of the body, even if it often manifests on or around the area that has been exposed to the allergen.
It can last for a few minutes or even days and, even in very rare circumstances, even several months and years.
Anyone can be affected; about 20% of the population suffers at some time in their lives; boys, seniors, men and women can have it indiscriminately.

10) Recognize the triggers and learn How to prevent urticaria
Urticaria is a reaction to an allergen. The allergic response occurs when the immune defences are activated in an excessive and uncontrolled way against any element that is identified as “foreign” to the organism.
Allergens are found everywhere in the surrounding environment; those that trigger urticaria may be food, over-the-counter or prescription drugs, insect bites and bites, chemicals, polymers such as latex, an infection, animal hair or dandruff, pollen, some plants and even physical stimuli, like a pressure, a scratch, temperature and even exposure to the sun.

11) Recognize the urticaria.
Usually, it is rather easy to diagnose, because it has a well defined and characteristic appearance that can be identified with a simple observation; instead, identify the cause and avoid future recurrences can be more complex.
Unless you know it from experience, have not seen the insect or spider that has bitten you or do not know exactly which food or drug causes hives, you may need to perform allergy tests to observe skin reactions to different substances.
Sometimes, a blood test is required and in some situations even a skin biopsy to examine the skin under a microscope.
