What is hay fever?

What is hay fever

Hay fever is a common allergy that affects many people in the UK. It’s like an allergic reaction to pollen, which is the fine powder from flowers, plants, and trees that floats in the air, especially during spring and summer. 

Moreover, if you have hay fever, your body thinks pollen is a troublemaker, so it triggers an immune response. This makes the lining of your nose and eyes swell and release chemicals to protect you from what it sees as a threat. This can lead to symptoms like sneezing, a runny nose, and itchy eyes.

Common hay fever symptoms 

Common hay fever symptoms are a result of the immune response, affecting the nose, throat, and eyes, which share interconnected tubes. These symptoms include:

  1. Runny nose.
  2. Itchy nose.
  3. Blocked nose.
  4. Itchy throat.
  5. Itchy eyes.
  6. Watery eyes.
  7. Sneezing.
  8. Exacerbation of asthma symptoms, including breathlessness and wheezing for individuals with asthma, as hay fever can worsen their condition.

The Importance of Hay Fever Tablets

  1. Effective Symptom Relief: Hay fever tablets, known as antihistamines, are a fast-acting and highly effective solution for alleviating most hay fever symptoms. They work by blocking the body’s immune response to pollen, particularly the release of histamine, which triggers these symptoms.
  2. Improved Quality of Life: Many individuals with it experience disruptions in their daily lives due to symptoms. Hay fever tablets can help enhance the quality of life by addressing issues like sleep disturbances, tiredness, irritability, and practical problems.
  3. Protection Against Infection: Untreated hay fever, or allergic rhinitis, can cause mucus in the nose to stagnate, increasing the risk of infections.
  4. Protection Against Asthma: For people with asthma, unmanaged by it can worsen their condition. Moreover, inhaling pollen into the lungs can also increase the risk of developing asthma. 

Both conditions often coexist, with a significant percentage of patients having both allergic rhinitis and asthma. Therefore, treating it is essential to safeguard against the worsening of asthma and potential asthma development

When to Begin Taking Hay Fever Tablets

Hay fever tablets are most effective when used as a preventive measure in addition to immediate symptom relief. If you’re a regular hay fever sufferer and know the season when your symptoms usually start, it’s advisable to commence taking hay fever tablets in advance. 

Margaret Kelman suggests beginning this regimen ideally one to two weeks before the hay fever season, although predicting this precisely can be challenging.

In addition, this proactive approach is crucial because once your allergic response to pollen is triggered, it becomes more challenging to control. A cascade of inflammatory cells heads to your nose where the pollen is causing the irritation, leading to worsening symptoms.

Starting antihistamines, such as hay fever tablets, a few weeks in advance effectively helps block this reaction before it commences. For some individuals, this proactive approach may even prevent symptoms entirely, while for others, it can, at the very least, reduce discomfort and potentially lower the risk of an asthma exacerbation.


It also known as acetaminophen in some regions, is a widely used over-the-counter medication for relieving pain and reducing fever. It comes in various forms, including tablets, capsules, liquid suspensions, and suppositories, making it easily accessible to a variety of users.

Key points about paracetamol:

Pain Relief and Fever Reduction: Paracetamol is primarily employed to alleviate different types of pain, such as headaches, muscle aches, toothaches, and discomfort associated with conditions like arthritis. It’s also effective in reducing fever during illnesses.

Mechanism of Action: While the precise mechanism isn’t fully understood, it’s believed that it works by reducing the production of prostaglandins in the brain, which are substances that contribute to pain and fever.

Dosage and Usage: Proper usage involves adhering to the recommended dosage instructions on the product’s packaging or as advised by a healthcare provider. It’s essential not to exceed the recommended dose to avoid potential adverse effects, especially on the liver.

Safety and Precautions: Further, it is generally considered safe when taken within the recommended dose. However, individuals with preexisting liver conditions, a history of heavy alcohol consumption, or those taking specific medications should consult a healthcare professional before use. It’s also crucial to avoid taking multiple products containing paracetamol simultaneously to prevent accidental overdose.

Potential Side Effects: While most people tolerate paracetamol well, some may experience mild side effects, such as nausea or stomach discomfort.

Interactions with Other Medications: It can interact with certain medications, making it important to consult a healthcare provider to ensure its safe use alongside other drugs.

Special Considerations:  Generally considered safe for use by pregnant or breastfeeding individuals with guidance from a healthcare provider. Children’s paracetamol formulations are available and should be administered following age-specific dosing recommendations.

Over-the-Counter Availability: Lastly, it is widely accessible without a prescription and is a common ingredient in many over-the-counter pain relief medications.
