Tous les traitements contre le rhume des foins sont-ils identiques ?

Heureusement, il existe de nombreux traitements disponibles pour soulager rhume des foins symptômes, mais tous les traitements contre le rhume des foins sont-ils identiques ? Et comment pouvez-vous choisir le right treatment pour vos allergies et symptômes ?

Dr Deborah Lee de Pharmacie en ligne Dr Fox explique les différences entre les médicaments contre le rhume des foins et comment choisir celui qui vous convient.

Up the ante

Hay fever is an allergy to pollen. When you breathe in pollen particles they get trapped in your nasal passage and airways and are recognised by the body as a foreign substance.

"Cela déclenche la cascade d'inflammation, de la même manière que lorsque votre corps rencontre d'autres organismes étrangers - tels que grippe, or respiratory viruses, for example," Dr Lee explains.

"Histamine is one of many molecules your body releases when it mounts a local inflammatory reaction. Histamine is a cell-signalling molecule that causes small blood vessels to dilate, which increases blood flow to the area.

"Blood vessels also become leaky, to facilitate white blood cells quickly reaching the site. In hay fever, histamine is the major cause of itching and irritation, as well as runny eyes and a runny nose."

There are three main types of hay fever treatment, Dr Lee says, all working in different ways to tackle the telltale symptoms. They include:

• Antihistaminiques - qui bloquent la libération d'histamine.

• Corticosteroids - powerful anti-inflammatories.

• Nasal decongestants - which reduce the swelling of blood vessels in the nose.

Pick of the bunch

So, how can you pick the right treatment for you? That depends entirely on your symptoms.

"When choosing a hay fever treatment, it's important to choose products that are most likely to benefit your specific symptoms," Dr Lee says. "However, as the central cause of hay fever is due to histamine release, most hay fever sufferers would be offered an antihistamine tablet to take by mouth."

Let's take a closer look at each medication and how they work.

Antihistaminiques

"Antihistamines generally benefit all hay fever symptoms, apart from nasal blockage. However, for best effect they need to be taken before symptoms develop," Dr Lee explains.

"You may choose to take them as and when. For example, if you know the pollen count is forecast to be high that day, you take the tablet before you go outside. However, most hay fever sufferers will take an antihistamine every day during the hay fever season to try to keep on top of their symptoms."

Le Dr Lee suggère de chercher antihistaminiques qui incluent acrivastine, bilastine, cétirizine, desloratadine, fexofénadine, loratadine, mizolastine ou rupatadine.

If you are pregnant or breastfeeding, you will not be able to take antihistamines.

Corticostéroïdes

Si vos symptômes ne sont pas contrôlés par un antihistaminique oral, vous pourriez bénéficier d'un stéroïde nasal spray.

"These products are often better than antihistamines if local symptoms are a problem, but they need to be started preferably before the hay fever season begins and used regularly," Dr Lee adds.

"Occasionally, if your symptoms are very severe, your GP may prescribe a short course of oral steroids in order to give you symptomatic relief.

"Un spray nasal combinant un antihistaminique et un stéroïde peut être très efficace." Dymista is an example of this.

Some nasal sprays should not be used for more than 2-4 weeks, including those containing betamethasone and fluticasone.

Nasal decongestants

Comme le nom l'indique, nasal decongestants sont des médicaments que vous inhalez par le nez.

"These cause the blood vessels lining your nose to shrink, relieving swollen nasal passageways. They should only be used for up to seven days at a time as with longer-term use you can develop a rebound, persistent nasal discharge," Dr Lee says.

Gouttes pour les yeux peut également être utilisé pour soulager les yeux qui coulent et démangent.

"A specific type of eye drops, called sodium cromoglycate, can be very effective for hay fever. These prevent the release of histamine and must be used regularly," Dr Lee adds.

"Otherwise, antihistamine eye drops are also very effective. These contain azelastine and olopatadine."

Plagued by pollen

If you find your hay fever treatment isn't working, there could be several reasons why.

Firstly, it's important to make sure you start using treatments before your hay fever actually kicks in, Dr Lee says.

"Pour de meilleurs résultats, commencez le traitement au moins deux semaines avant que le taux de pollen ne commence à augmenter. Le saison du rhume des foins généralement de mars à septembre, mais il peut être préférable de commencer le traitement à la mi-février", ajoute-t-elle. Cependant, il convient de souligner que le rhume des foins de nombreuses personnes n'est déclenché que par le pollen de graminées, dont les niveaux sont les plus élevés de mai à juillet.

"This may seem an alien concept, but the idea is to prime your body, so it is ready for action when the onslaught comes on."

You also need to make sure you are taking your treatment consistently - taking a 'once-a-day' antihistamine every couple of days isn't going to help your body keep your histamine levels under control.

Sometimes though, things are just out of your control. A bad pollen year can mean that while hay fever treatments have some impact, they're just not as effective.

"Some years the pollen count is particularly high. At present the pollen count is high, and many hay fever sufferers are having an especially bad time," Dr Lee says. "Tree pollen is high in the spring, grass pollen is high in the summer, and weed pollen is high in the autumn."

Si vous avez du mal avec vos symptômes et que vos traitements ne fonctionnent pas aussi efficacement, il existe plusieurs autres mesures que vous pouvez prendre pour vous aider ease hay fever.

• Wear a mask that fits snugly over your nose and mouth when you go outside - luckily, we're already doing that because of COVID.

• Wear wraparound sunglasses to keep pollen out of your eyes.

• Put a rim of Vaseline just inside your nose to trap pollen when you breathe in.

• Stay indoors with doors and windows closed as much as you can.

• Vacuum and dust at home regularly to get rid of pollen and other allergens.

• Buy a pollen filter for the air vents in your car.

• Change your clothes when you come in from outside and wash them, shower, and wash your face and hair.

• If you wear contact lenses, consider giving your eyes a break and wearing glasses for the time being to avoid eye irritation.

Snuff out the sniffles

Si vous n'êtes pas sûr de quel traitement vous convient, vous pouvez parler à votre local pharmacist concernant vos symptômes. Ils seront en mesure de vous conseiller et de vous fournir une gamme d'options contre le rhume des foins qui vous conviennent. Certains médicaments normalement disponibles uniquement sur ordonnance, comme Dymista, sont disponibles chez les pharmaciens grâce à Patient Access.

But if your symptoms are still not going away then you may need to consult your GP.

"You may need to consult the doctor if your hay fever isn't responding to treatment. This might be because the diagnosis is wrong, or because there are hay fever complications," Dr Lee says.

"Un diagnostic différentiel pour le rhume des foins pourrait être un autre type de la rhinite, ou une infection des voies respiratoires supérieures. Les complications peuvent inclure sinusite, un milieu infection de l'oreille, la conjonctivite ou, chez certaines personnes, être associé à une poussée de asthme symptômes.

"If hay fever is extreme and severe, the pharmacist may suspect you might need a course of oral steroids."
