What Are Allergies and Hay Fever?

Allergies occur when the immune system reacts abnormally to substances that are typically harmless, known as allergens. Hay fever, or allergic rhinitis, is one of the most common forms of allergy in the UK, triggered primarily by pollen from trees, grasses, and weeds. Allergy and hay fever tablets UK sufferers rely on are designed to reduce the body's overreaction to these triggers. Symptoms can range from mild irritation to more severe discomfort that affects work, sleep, and everyday activities.

Seasonal Allergic Rhinitis (Hay Fever)

Seasonal allergic rhinitis — commonly known as hay fever — typically flares between late March and September in the UK, coinciding with high pollen counts. Tree pollen tends to peak in spring, grass pollen in early summer, and weed pollen through late summer and autumn. Many people find their symptoms worse on warm, dry, and windy days.

Perennial Allergic Rhinitis

Perennial allergic rhinitis occurs all year round and is usually triggered by indoor allergens such as house dust mites, pet dander, and mould spores. People with this form of allergy may benefit from long-term allergy medicine available online in the UK rather than purely seasonal treatments.

What Are the Symptoms of Hay Fever and Allergies?

Recognising the symptoms of hay fever and allergies can help you choose the most appropriate treatment. Symptoms are caused by the release of histamine in the body following allergen exposure, and they can vary in severity from person to person.

  • Frequent sneezing and a runny or blocked nose
  • Itchy, red, or watery eyes
  • An itchy throat, mouth, nose, or ears
  • Loss of smell
  • Headaches and facial pressure
  • Fatigue and difficulty sleeping due to nasal congestion

How Do Allergy and Hay Fever Treatments Work?

Most allergy and hay fever tablets UK pharmacies supply work by blocking histamine receptors in the body. When you are exposed to an allergen, your immune system releases histamine, which triggers allergy symptoms. Antihistamines prevent histamine from binding to receptors and causing this reaction, reducing sneezing, itching, and a runny nose. Other treatments such as corticosteroid nasal sprays work by reducing inflammation in the nasal passages over time.

Antihistamine Tablets and Liquids

Antihistamines are the most widely used hay fever relief treatment in the UK. Newer, non-drowsy formulas such as cetirizine, loratadine, and fexofenadine are suitable for daytime use and typically provide relief within one to two hours. Older antihistamines such as chlorphenamine may cause drowsiness but can be helpful at night.

Nasal Sprays and Eye Drops

Corticosteroid nasal sprays, such as those containing beclometasone or fluticasone, are recommended when nasal congestion is the primary symptom. They are most effective when used regularly from the start of the pollen season. Antihistamine eye drops are ideal for relieving itchy and watery eyes caused by allergic reactions.

Combination and Barrier Products

Some products combine an antihistamine with a decongestant to address both runny nose and congestion simultaneously. Barrier balms applied around the nostrils can also help trap pollen before it enters the nasal passages, complementing other hay fever relief products.

Are There Any Side Effects?

Like all medicines, allergy and hay fever treatments can cause side effects. Non-drowsy antihistamines may occasionally cause headaches, a dry mouth, or mild gastrointestinal discomfort. Older antihistamines are more likely to cause drowsiness, so you should avoid driving or operating machinery after taking them. If side effects persist or concern you, speak to a pharmacist or your GP for personalised advice.

Who Can Use Allergy and Hay Fever Treatments?

Most antihistamines and nasal sprays are suitable for adults and children over a certain age, though this varies by product. Some formulations are specifically designed for children, while others are intended for adults only. Pregnant or breastfeeding women, people with liver or kidney conditions, and those taking other medications should always speak to a pharmacist or GP before starting any new allergy medicine. If you are unsure whether a product is right for you, professional guidance is readily available.

How quickly do hay fever tablets work?

Are hay fever tablets safe to take every day?

However, you should always follow the dosage instructions on the patient leaflet and speak to a pharmacist if you plan to use them long-term, especially if you have any underlying health conditions or take other medications.
