Allergies are a common health issue among millions of people around the globe, causing slight irritation through severe reactions. They arise when the immune system reacts to substances-things that otherwise are called allergens. These allergens include pollen, dust mites, pet dander, mould, and certain foods. There are no permanent cures for allergies, but several treatments have been proven to reduce or eradicate symptoms. This article discusses the best treatments for the most prevalent allergies.
Which Treatment Works Best?
-
Antihistamines
Antihistamines are one of the most commonly dispensed medications for allergies, and their mechanism is as a histamine antagonist. A histamine is a chemical whose reaction is an allergic reaction that is produced by the immune system during such an allergic reaction and provokes symptoms like itching, sneezing, and runny nose. It is available over the counter in pill, liquid, and nasal spray forms and prescription strengths. Some of the most common OTC antihistamines are cetirizine (Zyrtec), loratadine (Claritin), and diphenhydramine (Benadryl). Newer-generation antihistamines, such as Zyrtec and Claritin, are favoured as they are non-drowsy, so patients can still treat their allergies without sleepiness’s unwanted common side effects.
-
Decongestants
Nasal decongestants reduce the blockage and stuffiness of allergic rhinitis (hay fever) symptoms. Decongestants decrease the size of blood vessels in the nostrils, helping to quickly shrink the swollen tissues to open breathing passage. There are two types of decongestants: pills (pseudoephedrine) and nasal spray (oxymetazoline). Nasal sprays should be restricted to short-course use, lasting no more than three days, because extended use leads to rebound congestion, where symptoms worsen after the nasal spray is withdrawn. Oral decongestants can be used for longer periods but should be avoided by those with high blood pressure or heart disease since they may increase blood pressure.
-
Corticosteroids
Corticosteroids are a very effective class of drugs that help act to reduce the inflammation caused by an allergy. They are particularly good at treating nasal allergies and asthma. Nasal sprays containing types of nasal corticosteroids, such as fluticasone (Flonase) and mometasone (Nasonex), are often prescribed in the treatment of allergic rhinitis, and they are usually much better than antihistamines or decongestants at treating chronic allergies. Inhaled corticosteroids, including beclomethasone and budesonide, can reduce inflammation inside the lungs and airways, avoiding asthma attacks in individuals whose asthma is induced by allergens. Treatment usually requires long-term management and, thus, regular use for good benefits.
-
Immunotherapy (Allergy Shots)
It involves slowly administering small doses of the allergen to build tolerance and reduce allergic reactions. Environmental allergies like pollen, dust mites, and most insect sting allergies are treated with immunotherapy. Weekly to biweekly allergy shots are given for several months, followed by a maintenance period of less frequent shots for several years. This treatment requires commitment, but the long-term benefits are worth it, and regular medications are often no longer needed. SLIT, a new immunotherapy, recommends sublingual allergen tablets over intramuscular injections. Fans are increasing due to grass and ragweed pollen allergies.
-
Avoidance of Triggers
The best and most effective way to control allergies is by avoiding the allergen that triggers the symptoms. Of course, nobody can remove airborne allergens such as pollen and dust mites entirely from their lives, but the list of practical steps that one may take against such contact is rather long:
Pollen: Close windows, use air conditioning, and wear sunglasses and hats during peak pollen seasons. Showering after you have been outdoors will help shower them off your skin and hair.
Dust Mites: Cover mattresses, pillows, and box springs with allergen-proof bedding, wash bedding in hot water once a week, and vacuum using HEPA.
Pet Dander: If you have pets, avoid letting them in bedrooms or wash your hands immediately after touching any pet to prevent an encounter with allergens. Regular grooming of pets and household surface cleansing may also minimise dander.
Mould: The best way to control mould growth is to reduce the moisture levels in the house. This can be done in damp areas like basements and bathrooms by speeding up leak repairs, cleaning mouldy surfaces with bleach, or preventing mould allergies.
-
Saline Nasal Irrigation
Saline nasal irrigation is unblocking nasal allergy symptoms through a medical manoeuvre. This technique removes excessive mucus, allergens, and irritants from the nasal cavity by rinsing the nasal passages with a saline solution. Such irrigation devices include the neti pot, though squeeze bottles and battery-powered systems are other options available. Saline irrigation can be done daily during the allergy season or when outbreaks peak. It is safe for most individuals, except that distilled, sterile, or boiled water is required to prevent infections.
Natural Remedies
Some allergic individuals treat the allergy with natural remedies, but their efficiency might be minimal. One of the most popular is butterbur, a medication derived from a plant with anti-inflammatory properties. Scientific evidence shows that butterbur extract can combat allergic rhinitis like antihistamines, but there are no side effects related to drowsiness. The next is quercetin, a flavonoid found in fruits and vegetables. It can block the release of histamines and thus help alleviate allergic symptoms. This supplement is commercially available as an over-the-counter preparation to be taken as part of the allergy management plan. Another favourite home remedy is local honey, which has been proposed in some areas to treat pollen allergies. Eating small amounts of local pollen through honey is suggested to build tolerance to those allergens. Scientific evidence remains minimal for this remedy.
Allergy Testing
If allergy symptoms persist and are difficult to control, allergy testing is needed to identify the allergens. Several diagnostic tests are available whereby such allergens can be identified. The most common diagnostic tests are:
Skin prick tests: Small amounts of allergens applied to the skin
Blood tests: Examine the immune system’s reaction to such allergens.
Once the allergen is detected, a treatment program can then be devised. This could include medication, lifestyle adjustments, and strategies on avoiding allergens explicitly tailored to the individual’s allergen.
Allergies can have a pretty disruptive influence on quality of life. However, in many cases, suitable combinations of treatments enable people to manage and overcome even their worst symptoms. The most commonly used drugs for treatment include antihistamines, decongestants, corticosteroids, and immunotherapy, while natural remedies and avoiding allergy-causing elements also offer relief. However, immunotherapy can be an answer for long-term problems. It could help patients become desensitised to an allergen. All these aspects would be beneficial for finding a personalised treatment or treatment plan suited to the best interest of each patient. Moreover, should be followed with a consultation and testing by a healthcare provider.
