Antihistamines: How Long Do They Take to Work and Do They Make You Drowsy?

Do you suffer from allergy symptoms like itchy eyes, sneezing, and a runny nose? If so, this article is for you. Read on to learn more about antihistamines!

Those who experience hayfever know how challenging it can be to manage symptoms daily. Fortunately, there are medications available to help relieve these symptoms, and antihistamines are one such example.

Widely used to alleviate allergy symptoms, antihistamines often raise questions among consumers: how do they work? Do they all cause drowsiness? In this article, we will clarify these and other questions for you!

How Do Antihistamines Work?

Antihistamines are medications used for allergy relief. They work by blocking histamine receptors in the body.

Histamine is a chemical released by the immune system in response to allergens such as pollen, dust, mites, or pet dander. When histamine binds to its receptors, it triggers allergy symptoms like sneezing, itching, watery eyes, and a runny nose.

By blocking these receptors, antihistamines prevent histamine from causing these symptoms, providing relief.

How Long Do Antihistamines Take to Work?

The onset time of antihistamines can vary depending on several factors, including the specific formulation of the medication and individual characteristics of the person taking it.

First-generation antihistamines generally begin to take effect within 30 minutes to one hour.

Second-generation antihistamines, such as Histallay, start to work within the first hour of use. This is due to how these medications are metabolised in the body and the time required to reach the necessary concentration in the bloodstream to alleviate allergy symptoms.

However, it is important to note that noticeable symptom relief can occur well before the maximum onset time. For example, many users report feeling relief from itching or a runny nose within the first 30 minutes after taking a second-generation antihistamine, especially when taken on an empty stomach or with a little water.

Do Antihistamines Cause Drowsiness?

Many people associate antihistamines with drowsiness. Indeed, some medications cause this side effect. These medications cross the blood-brain barrier and affect histamine receptors in the brain, resulting in sedation.

Therefore, they are often used at night to help with sleep while treating allergy symptoms.

On the other hand, second-generation antihistamines, such as Histallay, have been specifically developed to minimise this side effect. They are less likely to cross the blood-brain barrier, meaning they are less likely to cause drowsiness.

Clinical studies show that most patients using second-generation antihistamines do not experience sedation, making them a preferred choice for those who need relief during the day or who perform activities that require concentration and alertness.

What Makes Histallay Different?

Histallay is a second-generation antihistamine that blocks the action of histamine without causing significant side effects like drowsiness.

This is particularly important for individuals who need to remain alert and focused during the day, such as drivers, students, or professionals operating heavy machinery.

Histallay is designed to provide effective relief while aiming to minimize side effects. Research suggests that regular use of Histallay may not lead to tolerance, allowing it to maintain its effectiveness when used as recommended.

In fact, it can be used for up to a year as a preventive measure against allergy flare-ups.

Why Choose Second-Generation Antihistamines?

Second-generation antihistamines, like Histallay, are often recommended by doctors due to their effectiveness and lower incidence of drowsiness.

They are highly effective in relieving allergy symptoms without compromising patients' quality of life.

For those who suffer from seasonal or perennial allergies, the use of a non-sedative antihistamine allows for greater flexibility and convenience, especially when compared to first-generation medications.

Conclusion

Understanding the onset time and side effects of antihistamines is essential for selecting the most appropriate allergy treatment.

While first-generation antihistamines may offer quick relief, they tend to cause drowsiness and other side effects.

Second-generation antihistamines, such as Histallay, provide effective symptom relief with a significantly lower risk of drowsiness, making them an ideal choice for many people.

By choosing Histallay, consumers can be confident they are opting for a medication that is effective and respects their need to stay alert and active during the day.
