What are allergy medications and where to buy them?

Allergies are an abnormal immune reaction to normally safe environmental exposures. A person can develop an allergic reaction in response to what his immune system considers a foreign substance. Such allergy-triggering substances are called allergens. A universal allergen does not exist, so everyone responds individually to different incitants. A particular allergy-causing agent that can provoke a severe allergic reaction in one person will go completely unnoticed by another.

While they all have different triggering factors, the way allergies develop is always the same. It all starts with an allergen getting into the human body via being inhaled, touched, or ingested. Once inside, allergens that the human body falsely recognizes as dangerous cause a prompt immune reaction and make our B-cells release allergen-specific antibodies, which then tie to mast cells. Further destruction of mast cells leads to repair chemicals like histamine being released and causes an allergic response.

The most commonly observed allergic symptoms include eye irritation, stuffy or runny nose, itching, sneezing, and mild skin rash. Swelling of the throat or tongue and trouble breathing can indicate a more severe allergic reaction that requires immediate medical aid.

Various allergy pills from India are growing highest demand in the UK, USA, Australia and other countries.

How does various allergy medications work and where to buy it?

Antihistamines

A group of medications indicated for the treatment of allergy-induced symptoms is called antihistamines. All of them can be divided into two categories: sedating and non-sedating antihistamines, depending on which generation of drugs they belong to. Sedating antihistamines are older generation medications that, while effectively relieving allergy symptoms, also cause sleepiness, dryness of the mouth, nausea, and even confusion. Newer generation non-sedating antihistamine drugs are much less likely to cause any of these symptoms, though some of them might have a mild sedation effect.

Antihistamines work by either preventing the development of an allergic reaction or by reducing the severity of its symptoms. The drugs target the histamine receptors and do not let them be activated by the released histamine.

Antihistamines come in a variety of forms, such as pills, creams, liquids, nasal sprays, and antihistamine eye drops. Some of these medicinal drugs are available on prescription only, while others allergy pills can be easily purchased OTC in your local pharmacy or online.

Corticosteroids

Corticosteroids are drugs designed to subdue inflammation caused by an allergy. Available as oral tablets, lotions, nasal sprays, and ophthalmic drops, corticosteroids are effective in treating nasal blockage, itching or running nose, and sneezing.

Mast cell stabilizers

These medications can prevent the development of an allergic reaction to common allergens by steadying mast cells and inhibiting the release of histamine. For mast cell stabilizers to be of benefit, a person taking them has to adhere to a frequent-dosing schedule.

Leukotriene inhibitors

Histamines aren’t the only chemicals released from mast cells in response to an allergen, there are also leukotrienes, which are inflammation-causing agents responsible for the production of excess mucus and airway constriction. The drugs can block the production of leukotrienes or their binding to their corresponding receptors.

Nasal anticholinergics

Nasal anticholinergics are medications used to treat such a symptom of hay fever as a runny nose. While anticholinergic nasal sprays effectively help to decrease watery secretions, they do not work to remove the nasal congestion.

Decongestants

Decongestants that come in the form of oral pills, nasal drops and sprays are intended to relieve nasal congestion by narrowing swollen blood vessels in the nose. However, decongestants cannot treat other symptoms of an allergy.

Immunomodulatory drugs

These topical drugs are designed to change the way our immune system behaves in response to an allergen. They are used mostly as second-line therapy for treating skin allergies in cases where other medications proved to be ineffective or unsuitable.

Epinephrine autoinjections

Injections of epinephrine are administered when a person develops a sudden and severe allergic reaction – anaphylaxis – and requires emergency treatment. Food allergens, insect bites, or medicinal drugs may cause such unexpected and acute reactions.

Levocetirizine

Levocetirizine is a new-generation non-sedating selective antihistamine medication that alleviates such allergic symptoms as running or itching nose, sneezing, and watery eyes, which are characteristic of hay fever.

Levocetirizine blocks the binding of histamine to its receptors and prevents the production of other allergy chemicals that would otherwise cause elevated blood flow to the site and inflammation. By doing this, Levocetirizine offers quick relief of the common hay fever symptoms.

Adult patients are recommended to swallow one whole pill of Levocetirizine with some water once daily, right before or after meals. Taking a pill every day is necessary for people who are exposed to an allergy-causing agent. For example, when the hay fever season is underway, and pollen counts are high, patients should use a pill Levocetirizine every single day until it is over.

Even though Levocetirizine represents the non-sedating selective class of antihistamine medications, it can still produce a mild sedating effect on some people and sometimes cause drowsiness and weakness.

Statistically, 10% to 30% of the world’s adult population, and around 40% of children have allergic rhinitis. This is caused by their immune system being overprotective and mistakenly recognizing pollen, house dust mites, or pet dander as life-threatening substances. As a way to protect itself, our immune system releases certain chemicals, including histamine, designed to destroy the allergen.

Currently, there is no treatment for allergic rhinitis that could ensure a life-long recovery. People affected by it are also more susceptible to developing other serious health problems such as allergic maxillary sinusitis and inflammation of the middle ear.

There are a few things that you can do to help yourself survive through a hay fever season:

  • always wear sunglasses when outside

  • close the windows in your room to prevent any pollen from getting in

  • get your clothes changed and have a shower every time you come home from the street

If you need something to relieve your hay fever symptoms, do not rush to your doctor for a prescription, some of the best antihistamine medications might be available over-the-counter in your local pharmacy or online.
