What’s the difference between true food allergy and food intolerance?
A true food allergy affects your immune system. Even a small amount of food may trigger a range of symptoms such as an itchy sensation inside the mouth, throat, or ears, a raised itchy red rash, swelling of the face, around the eyes, lips, tongue, and roof of the mouth, or vomiting. These symptoms can be life-threatening. In comparison, food intolerance often affects your digestive system.

When does hay fever season start?
Hay fever is usually worse between late March and September, especially when it's warm, humid, and windy. This is when the pollen count is at its highest.

What is the influence of climate change to pollen patterns in the UK?
A climate change may lengthen the UK pollen season and potentially make pollen concentrations higher. It’s possible that climate change can lead to changes in the strength of pollen. The UK is also facing a threat from changes in the geographical distribution of allergenic plants, due to climate change, with invasive species such as ambrosia being on the watch list. A single ragweed plant can produce a billion grains of pollen per season and its pollen causes strong allergic reactions.

Antihistamines and Histallay®

How are Second-generation Antihistamines different from First-generation Antihistamines?
As the name suggests, First-generation antihistamines, such as chlorpheniramine and diphenhydramine were the first kind to get approved by the Food and Drug Administration (FDA), and became available on the market in the early 1940s. Second-generation antihistamines, like fexofenadine (the active ingredient in Histallay), became available for general use in the 1980s. One of the key attributes of first-generation antihistamines that differentiate them from second-generation antihistamines is that they cross your blood-brain barrier (BBB) that results in drowsiness.

What exactly is the blood-brain barrier (BBB)?
Your brain is the control center of your body and it needs to be protected from the entry of unwanted substances such as toxins, harmful bacteria and viruses. The blood-brain barrier (BBB) is a protective layer that acts like a gatekeeper and keeps these harmful substances out and only allows the transfer of useful substances such as nutrients, oxygen and essential molecules.
First-generation antihistamines, while effective in blocking the action of histamine, also have a significant drawback. They can cross your blood-brain barrier (BBB) and enter your brain. This leads to the feeling of drowsiness, sedation and sometimes can make you feel dizzy or confused. In simple terms, they make you feel sleepy and tired because they affect the normal functioning of the brain.
On the other hand, Second-generation antihistamines, like Histallay, were designed to have less impact on the brain. They are more selective in their action, and have limited ability to cross the blood-brain barrier (BBB). As a result, they cause minimal or no drowsiness, making them more suitable for daytime use.
