What Is Hay Fever and Allergic Rhinitis?

Hay fever, also known as allergic rhinitis, is one of the most common allergic conditions in the UK, affecting around one in five people. It occurs when the immune system overreacts to airborne allergens, triggering a range of uncomfortable symptoms. OTC hay fever relief products — including antihistamine tablets, nasal sprays, and eye drops — are widely available without a prescription and can help manage these symptoms effectively.

Seasonal Hay Fever

Seasonal hay fever typically occurs during spring and summer when tree, grass, and weed pollen levels are at their highest. Symptoms often flare between March and September, depending on which pollen triggers your reaction. This is the most common form of allergic rhinitis in the UK.

Perennial (Year-Round) Allergic Rhinitis

Perennial allergic rhinitis occurs throughout the entire year and is usually triggered by indoor allergens such as dust mites, pet dander, and mould spores rather than seasonal pollen. Sufferers may find that OTC allergy relief tablets and nasal sprays provide consistent symptom control regardless of the season.

What Are the Symptoms of Hay Fever?

Hay fever symptoms can range from mildly irritating to seriously disruptive, affecting sleep, concentration, and quality of life. Recognising the signs early means you can begin treatment promptly and choose the most appropriate OTC hay fever relief for your needs.

  • Frequent sneezing and a runny or blocked nose
  • Itchy, red, or watery eyes
  • An itchy throat, mouth, or ears
  • Facial pressure or sinus pain
  • Fatigue and difficulty sleeping due to nasal congestion
  • Reduced sense of smell or taste during peak pollen season

How Do Hay Fever and Allergy Treatments Work?

OTC hay fever treatments work by targeting the body's allergic response in different ways, depending on the type of product used. Understanding how each treatment works can help you choose the right combination for your symptoms.

Antihistamine Tablets

Antihistamines block histamine receptors in the body. When you are exposed to an allergen, your immune system releases histamine, which causes the classic symptoms of hay fever. Antihistamine tablets — including non-drowsy antihistamine options such as cetirizine, loratadine, and fexofenadine — prevent histamine from binding to receptors, reducing sneezing, itching, and a runny nose. Older antihistamines such as chlorphenamine may cause drowsiness.

Nasal Sprays

Corticosteroid nasal sprays work by reducing inflammation in the nasal passages. They are particularly effective for nasal congestion and are most beneficial when started a few days before the pollen season begins. Decongestant nasal sprays offer faster but shorter-term relief and should not be used for longer than seven days continuously.

Antihistamine Eye Drops

Eye drops designed for allergic reactions work directly at the eye surface to relieve itching, redness, and watering caused by pollen or other airborne allergens. They are often used alongside antihistamine tablets for more complete symptom control.

Are There Any Side Effects?

Most OTC hay fever treatments are well tolerated, but some people may experience side effects. Older antihistamines can cause drowsiness and dry mouth. Nasal sprays may occasionally cause mild nasal irritation or nosebleeds with prolonged use. Always read the patient information leaflet and speak to a pharmacist or GP if you are concerned about any side effects.

Who Can Use Hay Fever and Allergy Treatments?

Most OTC hay fever treatments are suitable for adults and children over a certain age, which varies by product. Many non-drowsy antihistamine tablets are licensed for children aged two and above, while some nasal sprays are suitable from age six. Pregnant or breastfeeding women and those taking regular medication should always speak to a pharmacist before starting any new allergy treatment to ensure it is appropriate for their circumstances.

  1. Adults and children aged two and above (product-dependent)
  2. Those with seasonal or year-round allergic rhinitis
  3. People experiencing mild to moderate allergy symptoms
  4. Anyone who has previously used antihistamines without adverse reaction
