Antihistamines: What They Are and How Many You Can Take

For those who suffer from hayfever, the symptoms can significantly impact their quality of life. Runny or blocked nose, itchy or watery eyes, skin rashes, sneezing, and even coughing are just a few examples. Fortunately, antihistamine medications, like Histallay®, can relieve these symptoms.

Antihistamines are widely used to ease allergy symptoms. They work by blocking the action of histamine, a substance released by the immune system in response to allergens. Histamine is primarily responsible for the symptoms mentioned above.

But are all antihistamines the same? Do they all have the same effects? The answer is no. These medications can vary widely. In this article, we will explore this topic further.

First-Generation Antihistamines

First-generation antihistamines were the first to be developed and are effective in relieving allergy symptoms. However, they often come with strong side effects.

Medications such as diphenhydramine and chlorpheniramine are rapidly absorbed by the body and easily cross the blood-brain barrier, which can lead to drowsiness and sedation. This means they are not safe for those who need to drive, operate machinery, or simply take the medication during the day.

These medications are also short-acting, meaning they do not last 24 hours in the body, requiring multiple doses throughout the day. This can be quite inconvenient. Despite this, they continue to be widely used around the world.

Second-Generation Antihistamines

Second-generation antihistamines, like Histallay®, overcome the limitations of first-generation medications. Histallay® does not cause drowsiness after use, making it suitable for daytime consumption.

This is because it was formulated not to cross the blood-brain barrier, meaning it does not cause drowsiness or sedation.

Furthermore, Histallay® offers prolonged relief from allergy symptoms, lasting up to 24 hours. This means just one tablet per day is enough for full control of hayfever symptoms. There is no drowsiness, nor the inconvenience of having to take multiple pills throughout the day.

Its effects are comprehensive: Histallay® works against sneezing, nasal congestion, runny nose, itchy eyes, and throat irritation. As a result, Histallay® has a direct impact on the individual's quality of life.

How to Take Histallay® - Dosage and Duration

Since Histallay® has a prolonged effect on the body, it is advised to take one tablet per day. Choose the most convenient time, and you will be free from hayfever symptoms for up to 24 hours. It can be taken daily for up to a year, depending on the patient's needs and medical advice.

Moreover, Histallay® can be used as a preventive treatment. For example, when the pollen season begins, it is possible to take Histallay® even before symptoms appear, preventing attacks and improving your quality of life.

How Many Antihistamines Can We Take Per Day?

For first-generation antihistamines, it is important to follow the leaflet instructions and be aware of the medication's duration in the body.

As mentioned earlier, when it comes to second-generation antihistamines like Histallay®, the recommended dosage is one tablet per day. This dosage provides 24-hour symptom relief. In case of doubt or specific situations, always consult your doctor.

Other Measures to Prevent and Alleviate Hayfever

In addition to using second-generation antihistamines like Histallay®, there are several measures to prevent - and even alleviate - hayfever symptoms:

• Pollen:

  During spring and summer, pollen released by trees and plants is one of the main triggers of hayfever. This is the reproductive season for many plants in the UK, making pollen highly abundant. To avoid triggering an allergic reaction, keep windows closed during peak pollen times, use air filters, and avoid outdoor activities in the early morning and late afternoon when pollen levels are highest. Wearing sunglasses can also help by preventing pollen from coming into contact with your eyes.

• Mould:

  Mould thrives in humid environments, so controlling humidity and keeping surfaces clean and dry is essential, whether at home or at work. Use dehumidifiers and ensure good ventilation in the areas where you spend most of your time.

• Pet Dander:

  Unfortunately, those who suffer from hayfever triggered by contact with animals need to minimize this exposure. If you have pets, you can, for example, designate certain areas of your home, such as your bedroom, bathroom, and kitchen, as pet-free zones.

• Dust Mites:

  Dust mites are a common cause of hayfever. The issue is significantly reduced when the environment is kept clean. Change your bed linens regularly and wash them in hot water. Do the same with towels, and consider using anti-allergy covers for your mattress and pillows.
