How Do You Treat An Allergic Reaction?

Allergic reactions can be caused by various factors, making it challenging to determine which treatments will work best. Nevertheless, home remedies and over-the-counter medications can effectively reduce the severity of symptoms.

Approximately one-third of adults in the EU have an allergy, whether it's related to the environment or food. As such, allergic reactions are a frequent occurrence.

This article examines the different treatments available for allergies and allergic reactions, depending on the cause and symptoms. Treatments range from over-the-counter medications to Anaphylaxis. If you experience a severe allergic reaction, it is essential to seek immediate medical attention.

What Is An Allergic Reaction?

When an allergen enters the body, the immune system views it as a potential threat and responds by releasing histamine. This chemical triggers an allergic reaction, resulting in symptoms such as inflammation, sneezing, and coughing.

Treating Allergic Reactions

Various treatments can be used to ease the symptoms of an allergic reaction. These include home remedies, such as:


Antihistamines are effective in treating most mild allergic reactions, regardless of their source. These medications suppress the body's histamine production, thus alleviating symptoms such as sneezing, runny eyes, and skin irritation.

Antihistamines are available in various forms, such as tablets, liquids, and nasal sprays, which are designed to deliver the medication closer to the source of the allergic reaction or make it easier to swallow:

  • Nasal sprays

  • Liquids

  • Oral pills

  • Eye drops

  • Dissolvable tablets

Claritin (loratadine) and Zyrtec (cetirizine), second-generation antihistamines, are less likely to cause drowsiness than first-generation antihistamines like Benadryl. However, pregnant individuals, those with a heart condition, or those with a liver disorder should seek medical advice before taking any antihistamines.

Nasal Decongestants

Decongestant medications can help reduce sinus discomfort and symptoms such as a sore throat or coughing. However, long-term use of decongestant medicines should be avoided, as they can have undesired side effects. It is essential to follow the dosage instructions provided on the product label, and generally, decongestants should not be used for more than a week.

Anti-Inflammatory Medication

Allergies can cause discomfort, such as pain, swelling, and cramping, and taking nonsteroidal anti-inflammatory medications (NSAIDs) can temporarily relieve these symptoms.

Avoid The Allergen

Knowing what substances can trigger them, especially food allergens, is essential to avoid allergic reactions. When avoiding allergens is not an option, taking antihistamines or decongestants can help reduce allergic reaction symptoms. Taking preventive measures is critical to managing allergies.

Use A Saline Sinus Rinse.

Allergens can often trigger sinus issues, but rinsing the nasal cavities with a saline solution can help remove these allergens and open the airways.

Treating Environmental Allergies

To tackle airborne allergens such as pollen, dust, and mould spores., other treatment methods are available, including:

  • Menthol, honey, and ginger throat lozenges soothe sore throats

  • If you have been exposed to an allergen, you should wash all your clothing afterwards

  • Reduce nasal congestion with a few minutes of exercise

Treating Allergies On The Skin

When suffering from allergies that cause skin symptoms due to allergens found in animal saliva, poisonous plants, drugs, chemicals, and metals, additional treatments may include:

  • Cold compresses

  • Topical corticosteroid creams or tablets

  • Moisturising creams

Treating Severe Allergies

Individuals suffering from severe or chronic allergies should consult a healthcare professional for proper diagnosis and treatment.

Allergy treatment options include:

  • Immunotherapy is commonly known as allergy shots.

  • Prescription asthma medications, including bronchodilators and inhaled corticosteroids.

  • Oral cromolyn is utilised for managing food allergies.

  • Drug desensitisation therapy is designed for specific allergens.

Natural Remedies For Allergic Reactions

Despite a lack of scientific backing, many people turn to herbal supplements and extracts as a form of traditional medication to treat and prevent allergic reactions, particularly seasonal ones. Some individuals may find that some natural remedies can help to reduce their symptoms.

  • Dietary Changes: Thus, a low-fat diet may be an effective way to manage allergies.

  • Bioflavonoids: These chemicals, known as flavonoids, are thought to help block the release of histamines, which are the chemicals responsible for causing the symptoms of allergies.

  • Supplements: Allergy sufferers may benefit from consuming flaxseed oil, zinc, and vitamins A, C, and E, as these substances may help to reduce symptoms.

  • Acupuncture: Acupuncture has been known to relieve specific symptoms for some individuals.

Identifying And Treating Anaphylaxis

Anaphylaxis is a severe and life-threatening allergic reaction that can cause the body to go into shock. The symptoms appear suddenly and may include difficulty breathing, swelling of the throat and tongue, hives, and dizziness. If not treated promptly, Anaphylaxis can lead to coma, organ failure, and even death. It is essential to seek medical attention immediately if you experience symptoms of Anaphylaxis.

The following symptoms characterise Anaphylaxis:

  • Swollen Tongue, Throat, Mouth, and Face

  • Tingling in the palms of the hand, Soles of the feet, and Lips

  • Rapid but weak pulse

  • Difficulty breathing

Administer an EpiPen, a self-injectable dose of epinephrine, into the person's thigh immediately if available, as it is the most effective treatment for Anaphylaxis.

In the event of Anaphylaxis, the following steps should be taken:

  • Encourage the individual to stay calm and composed.

  • If vomiting occurs, gently turn them onto their side and ensure their mouth remains clear.

  • Guide the person to lie flat on their back, elevating their feet approximately one foot above the ground.

  • Ensure loose clothing or remove any constricting garments.

  • Refrain from providing food or drink, even if requested.

  • If the person is not breathing, perform CPR with approximately 100 firm chest compressions per minute until emergency services arrive.

This is usually enough to reverse the symptoms of Anaphylaxis. Epinephrine or adrenaline can also help reduce the airway's swelling and make breathing more accessible for the patient.


For more severe cases, a doctor may recommend corticosteroid or immunotherapy treatments. It is also important to avoid triggers and allergens as much as possible.

People should also seek medical attention if they experience difficulty breathing, chest pain, or dizziness. They should also be aware of any triggers that may have caused the reaction and try to avoid them in the future.
