Allergies

Allergies can cause significant discomfort due to your body having a reaction to an allergen. An allergic reaction occurs when your body responds to typically harmless substances such as pollen, dust, or animal fur. Symptoms range from mild to severe and, for certain individuals,  can cause significant health problems. Generally, allergies are a long-lasting condition that can cause discomfort throughout the year. For many allergy sufferers, medication can help manage symptoms and improve their quality of daily life. If your allergies are severe, your GP can work with you to diagnose your allergies and offer a tailored treatment plan.

FAQ

What are common allergens?
Pollen allergies, known as hayfever or allergic rhinitis, occur when the immune system overreacts to pollen from trees, grasses, or weeds. It is a very common allergy that affects both children and adults. Symptoms may include sneezing, runny or stuffy nose, itchy eyes, and throat irritation. These allergies are most prevalent during specific seasons when plants release pollen into the air. Dust mite allergies are another common allergen that results from the immune system's reaction to microscopic creatures found in household dust. These tiny mites are often found in bedding, furniture and carpets. Dust mite allergies are particularly bothersome for those who spend significant time indoors. Animal dander allergies are another common allergen caused by hypersensitivity to proteins found in the skin cells, saliva, or urine of pets including cats, dogs, or rodents. When the allergy sufferer is exposed to these proteins, they may experience sneezing, coughing, skin rashes, itchy eyes, or asthma exacerbations. Managing animal dander allergies often involves minimising contact with pets or implementing allergen-reduction strategies in the home, for example frequent hoovering.
What are common allergy symptoms?
Allergy symptoms can vary widely depending on the allergen and the individual's reaction. Common symptoms include sneezing, itching, nasal congestion, runny nose, coughing, wheezing, shortness of breath, hives, and swelling. In severe cases, allergies can lead to anaphylaxis, a life-threatening allergic reaction. Anaphylaxis is a medical emergency and you must seek emergency medical assistance. Call 999 if you suspect someone is suffering from anaphylaxis.
When are allergy tablets most effective?

Allergy tablets like treatments like antihistamines start to work quickly and will help to relieve symptoms within an hour or two of being taken. The best time to take hayfever tablets and other allergy relief products is before you start to experience symptoms or come into contact with the substance that you're allergic to.

When should you not take antihistamines?

Antihistamines should not be taken alongside other prescription medications without first speaking with your GP. This includes antidepressants, indigestion treatments and cold remedies. You should also avoid drinking alcohol where possible, especially if your allergy tablets make you feel drowsy.

Are antihistamines safe?

There are multiple different types of antihistamine which can be taken safely by the majority of people, however, there are some circumstances in which you should consult with your GP first.

But speak to a pharmacist or GP for advice if you:

  • are pregnant or breastfeeding
  • need allergy treatment for a young child
  • are elderly or have an underlying health condition which may make you more vulnerable
  • are taking other medication 
Can I take two hayfever tablets in a day?

No, you should not take multiple antihistamines within a 24-hour period unless advised to do so by your GP.

Are hayfever tablets safe in pregnancy?

Certain allergy treatments should not be taken without a prescription while pregnant, including some antihistamines. You may be encouraged to try an alternate form of hayfever remedy instead, such as a nasal spray or eyerdrops. 

If you do require allergy tablets, Loratadine and Cetirizine are generally prescribed as these do not cause drowsiness.
