What’s on this page?
Desloratadine provides a quick relief from hay fever symptoms, remaining active for 24 hours after consumption. The success rate and efficiency of this medicine make it very popular among those affected. Within the United Kingdom alone, more than 10 million people are affected by hay fever each year. This allergic reaction occurs once a person is exposed to fine pollen particles. As such, it occurs during the period of year when certain plant species enter the reproductive phase of their annual cycle. Naturally, not everybody will react to pollen and those who do can be allergic to different plant species, meaning they will notice the symptoms at different times of the year.
The common symptoms of hay fever include:
- Runny nose
- Itching of the mouth and throat
- Itchy, red and irritated eyes
Taken as a whole, the typical symptoms of hay fever are usually called rhinitis or allergic rhinitis.
What causes hay fever?
On a bio-chemical level, the symptoms of hay fever are brought on by the reaction of the immune system to the presence of allergens. Once body detects the presence of a substance that is perceived as an irritant, it tries to deal with it the same way as it would if it was a typical infection – releasing histamine and increasing the blood flow to the affected region of the body. This is what leads to typical signs of inflammation and swelling.
However, as of now, scientists have yet to explain why hay fever manifests in some individuals and not in other. As is often the case, there are strong indications that genetics play a prominent role. At the same time, other experts hypothesised that so-called early conditioning plays a part too – exposure to certain irritants, including second-hand tobacco smoke during early childhood may be at a much greater risk.
Hay fever treatment and prevention
For most people, spring is the time when the symptoms of hay fever peak, coinciding with the highest levels of pollen in the air. Preventive measures are often recommended in order to decrease the chances of experiencing the symptoms. These include:
- Staying indoors during days when pollen concentration is especially high
- Limiting prolonged exposure to pollen
However, it’s unlikely that you would be able to completely avoid presence of pollen in your environment no matter which precautions you take. And if your symptoms are persistent and are causing you considerable discomfort, then treatment might be the best option.
