How Urticaria antihistamines work?

If you have ever had a skin allergy due to mast cells and histamines, especially urticaria, then you will  have heard about antihistamines.

A urticaria antihistamine is a drug that counteracts the effects of the histamines that cause urticaria. However the urticaria antihistamines do not treat the underlying cause of urticaria. They just provide temporary relief to the patient from the itching or burning sensation and they are not considered to be a permanent urticaria treatment.

Though they relieve the patient of his itching, you still need to be careful about many things related to urtiacria antihistamines, read here to learn about these precautions in my article.

An urticaria antihistamine is a drug that counteracts the effects of histamines that cause urticaria. However, urticaria antihistamines do not treat the underlying causes of urticaria. They only provide temporary relief from the itching or burning sensation and are not considered to be a permanent urticaria treatment.

Histamines are released by the mast cells, which are widespread throughout the skin. When these mast cells are triggered by certain stimuli, they release histamines into the adjacent area of the skin. These histamines then cause rashes, itching, burning sensations, swelling, and other problems according to the nature of the stimulus. These skin problems are called urticaria.

There are four major types of histamines defined by medical science: H1, H2, H3, and H4. Furthermore, H3 and H4 antihistamines are not used in common clinical practice and are merely used for experimental purposes. H1 and H2 antihistamines are inverse agonists. H2 antihistamines are usually used to reduce the secretion of gastric acid and to treat other gastrointestinal conditions, including peptic ulcers and gastroesophageal reflux disease.

H1 antihistamines are used to treat allergic reactions, including different types of urticaria. Other uses of H1 antihistamines include reducing local inflammation that occurs due to various conditions, such as insect stings, even if there is no allergic reaction. Some antihistamines can cause drowsiness; therefore, activities that require mental and physical vigilance should be avoided after taking them.

Remember that antihistamines are used to provide the patient temporary relief, and patients should avoid their permanent use, as some of them are addictive.

An urticaria homeopathic remedy can be extremely helpful in many cases, especially when the patient is suffering from cold induced urticaria, physical urticaria, or chronic urticaria.

According to the homeopathic approach, urticaria must be looked upon as an external sign of the internal system dysfunction and should be treated in conjunction with a thorough assessment of the entire human system instead of just treating the skin. The homeopathic principles state that skin affections are typically a sign of an internal problem, usually, as a result of lowered immunity and are not treated only with external applications. Most of the homeopathic medicines work towards eliminating the basic sensitivity to the triggers that cause urticaria in the first place.

The homeopathic approach not only treats urticaria but also eliminates the tendency to this hypersensitivity by treating the underlying causes. After using homeopathic medicines and with the passage of time, the texture of the patient’s skin also improves.

Generally, urticaria can be characterized without extensive exploration; for example, wheals of physical urticaria usually last less than one hour, whereas those of ordinary urticaria typically last from two to twenty-four hours. Urticarial vasculitis should be determined by performing a skin biopsy if wheals last longer.

Most of the time, urticaria remains idiopathic after physical, infectious, allergic, and drug-related causes have been excluded. Nearly 30% of patients with the ordinary presentation of chronic urticaria appear to have an autoimmune trigger.

What is Urticaria?

Urticaria, commonly referred to as hives, is a dermatological disorder that appears as red, raised eruptions on skin. It is also characterized by itching. The eruptions are of various sizes.

Symptoms of Urticaria

Red and white eruptions appear on the skin. These patches can appear on any part of the body. The eruptions may disappear after some time and reappear on another part. They will be characterized by itching, burning, and stinging. The symptoms may also include problems with digestion, fever, and weakness. Sometimes, changes in voice may also occur.

Causes of Urticaria

Urticaria can manifest due to food allergies, such as fish, eggs, tomatoes, chocolate, strawberries, cow’s milk, and spinach. Drugs such as penicillin, codeine, NSAIDs, and aspirin can also lead to this condition. Respiratory infections, fungal infections, hepatitis, malaria, and HIV can also cause urticaria. The bites of insects, such as bees, bedbugs, mosquitoes, and caterpillars can also trigger outbreaks. Stress, exposing the skin to extreme heat or cold, latex exposure, and environmental factors, such as dust, chemicals, and pollen may also be responsible for urticaria outbreaks. Exercising and pregnancy may cause this condition as well. It can occur in any age group. Contact with metals, such as nickel, using gloves, rubber materials, silk, or wool can lead to this condition. Insect repellents, dyes, hair sprays, nail polish, hand cream, perfumes, and toothpaste represent many of the things that we use daily, which can also cause an outbreak. Inhaling house dust, aerosols, animal dander, and mold spores can trigger urticaria. Some preservatives used in food may also be responsible.

Consuming a fruit-only diet for five days may be helpful in the treatment of this painful condition. After five days, it is important to eat a well balanced diet containing fruits, nuts, vegetables, grains, and plenty of water to treat Urticaria. Treatment using turmeric, rosewater, vinegar, and salt can be used to cure the eruptions. Oral antihistamines can be used to control the itching. Avoid using substances that may cause an allergic reaction, which could provoke an outbreak.

Does drinking cause Urticaria?

A doctor can give you many reasons for quitting alcohol. Let me add Urticaria to those reasons. You might not think  these two have any connection.

Urticaria from alcohol –actually, drinking alcohol, which has ethanol as a major facta, can have detrimental effects on  patients with urticaria.

Though not all the urticaria patients are troubled by alcohol,  patients of chronic urticaria should specifically consult a qualified doctor and seek advice about it.

If you are interested in this topic and want to learn more about urticaria alcohol,  read this detailed guide.

Urticaria from Alcohol is the result of an outbreak of urticaria in response to the consumption of alcohol. The ethanol contained in alcohol can provoke diverse responses in urticaria patients.Chronic urticaria patients should consult a doctor to seek advice on whether they should consume alcohol, as it can affect their skin problems.

Anaphylactic reactions to alcohol are rare, and most reactions to alcoholic beverages are secondary to other chemicals in the beverage, such as metabisulfite, papain, dyes, or yeast. However, in some cases, true allergic reactions occur, in which the stimulating agent is ethanol, which results in urticaria from alcohol.

Most of the time, the symptoms of anaphylaxis appear in such patients following the consumption of beer or wine. Many people experience urticaria rashes after ingesting ethanol. However, there are only a few known cases in which urticaria was triggered due to contact with ethanol. Therefore, patients who are already suffering from urticaria must be careful with their drinking habits because hives can be triggered after drinking alcohol. It is wise to consult a doctor and ask his advice regarding the routine and quantity of liquor that is safe to consume.

One of the most commonly opted for treatments is the intake of antihistamine. As the name suggests, antihistamine nullifies the effect of histamine, which is released by the mast cells as a result of stress or the allergic process. Unfortunately, antihistamine medication does not control the underlying causes of histamine release. Therefore, you feel better only when you take antihistamines, as the condition may reappear.

Is Stress Urticaria a common disease?

After reading this blog you might think that stress could cause all sorts of diseases. It might sound outlandish to you, but it is true that stress can even cause you Urticaria. In fact it is a major trigger for many urticaria patients.

Urticaria is a medical term for hives which usually results from an allergic process, but it can also be non-allergic. This   is the case with stress urticaria, also called stress induced urticaria.

Emotional stress can trigger some immunological changes in the mast skin which may lead to urticaria. Isn’t it an interesting topic? May be not for those who are suffering from it, though! Lets learn more about stress urticaria in my article here.

Urticaria is a medical term for hives, which usually result from an allergic process; however, it can also be non-allergic, which is the case with stress urticaria, also called stress induced urticaria. Emotional stress can trigger immunological changes in the mast cells, which may lead to urticaria. However, extreme stress may be responsible for chronic urticaria.

Patients with stress urticaria experience bumpy rashes on their skin, which may last for a few minutes to a few hours. Other symptoms include itch, pain, and difficulty in breathing if the lips and larynx are affected. In  rare cases, it can remain much longer, and if the rash remains over six weeks, it is called chronic urticaria.

Stress urticaria is usually caused by constant emotional stress and tension. If this occurs, and you develop a red, itchy rash, it is time to find ways to relax and relieve tension, or your skin problems are likely to worsen. However, you should also consider certain medical treatments.

Sometimes, people who suffer from stress can develop stress urticaria even when they are calm and relaxed. The reason is that emotional stress can provoke certain long lasting immunological changes, which may continue even when you are not stressed. When this occurs, you may get urticaria even when you are not currently under stress.

One of the most commonly opted for treatments is antihistamines. As the name suggests, antihistamines nullify the effect of histamine, which is released by the mast cells as a result of stress or the allergic process. Unfortunately, antihistamine medication does not control the underlying causes of histamine release. Therefore, you feel better only when you take antihistamines and the condition may reappear.

How could I develop Pruritic Urticaria?

How about getting a skin problem known as Prutric Urticaria, during pregnancy?

Of course it will give you pain and make your life a misery. It is a chronic hives-like skin rash that strikes some women usually in the third trimester of their pregnancy. It was formally identified and described in 1979. It can add to the suffering caused by pregnancy due to itching and swelling.

Though it does not threaten the mother or the unborn child, it can be extremely annoying due to the itching and pain. Let us try to learn more about it and how you can avoid or treat it in my comprehensive article about Prutric Urticaria.

Affecting about one in two hundred pregnant women, pruritic urticaria was formally identified and described in 1979. It is a chronic hives-like skin rash that strikes some women during pregnancy. It is commonly known in the United States as pruritic urticarial papules and plaques of pregnancy (PUPPP), and in the United Kingdom, it is usually referred to as polymorphic eruption of pregnancy (PEP).

Pruritic Urticaria has many other names, including late-onset prurigo of pregnancy and toxemic rash of pregnancy. Some people may confuse it with toxemia of pregnancy, which is another term for pre-eclampsia.

There is no long-term risk for the mother or the unborn child; however, itchiness can create a lot of the problems for the patient. In most cases, PUPPP begins on the stomach and spreads to other body parts, such as the legs, feet, arms, chest, and neck.

In various cases, the symptoms are different, and the appearance of the condition changes with the passage of time. In nearly 98% of cases, it starts with pruritic urticarial papules, which are itchy wheals – small, solid elevations of the skin. However, over half of the patients develop multiple forms of polymorphic redness, small blisters, and targetoid and eczematous lesions.

For temporary relief, the patient may apply topical moisturizing creams, aqueous, or emollient ointments on the affected area. Patients with serious conditions may apply class I or II corticosteroid creams and ointments. However, to treat extremely severe cases, oral corticosteroids can be used.

As your body is going through many chemical changes during pregnancy, abnormalities like pruritric urticaria are no surprise. However, you should take care when dealing with it, as it can affect your life as well as your baby’s life. Therefore, it is advisable to consult your doctor for proper treatment.

Learning about Treatment for Solar Urticaria.

You must have heard about ultraviolet radiation and its severe effect on humans skin. However, it is quite possible that you may not have heard about solar urticaria, a disease that can be caused by UV radiation. This disease is one example of how severely UVs can affect humans!

Luckily solar urticaria treatment is not as bad as many people think it is.

Solar urticaria is a uncommon subtype of physical urticaria, caused by exposure to sunlight, ultraviolet radiations or sometimes even visible light. For complete details about solar urticaria treatment read this detailed article.

First identified by P. Merklen at the start of the 20th century, solar urticaria is a type of physical urticaria caused by exposure to the sun. Before explaining the details of solar urticaria treatment, let us find out what it actually is and which symptoms characterize solar urticaria.

Solar Urticaria

Solar urticaria has many different names, including solar rash, sun rash, and sun allergy, etc. It is an uncommon skin problem in which exposure to ultraviolet radiation or sometimes even visible light causes urticaria. Solar urticaria can appear on both covered as well as uncovered areas of the skin.

The agent in the human body that is responsible for the reaction to ultraviolet radiation is known as the photoallergen. Owing to its similarity to other dermatological disorders, such as polymorphic light eruption or PMLE, solar urticaria can be difficult to diagnose.

Solar Urticaria Symptoms

The skin areas that are constantly exposed to the sun have a lesser chance of experiencing an outbreak of solar urticaria than do parts of the body that are thinly covered. The most obvious symptom of solar urticaria is a rash that appears within a few minutes after exposure to ultraviolet radiation. The patient may suffer from constant itching and pain. The urticarial reaction instigates in the form of pruritus, later progressing to erythema and edema in the exposed areas of the skin. In more severe cases, the patient may be subject to light-headedness, headache, nausea, and vomiting. Though it has been reported in only a few cases, patients have experienced bronchospasm.

Treatment of Solar Urticaria

Ultraviolet radiation causes mast cells to release histamines and blood enters the vessels, which causes inflammation. Taking antihistamines can suppress the activity of histamines. Fexofenadine is quite useful for patients with a low potency solar urticaria. However, Terfenadine, an H1 receptor antagonist, or medicine that combats the H1 receptor has been reported to be the most potent antihistamines for solar urticaria.

Some simple remedies include avoiding sun/ultraviolet exposure, washing the affected area with cool water, and using corticosteroid cream.
