What are the characteristics of antihistamines and anti-histamines?

 

"Antihistamine" used for allergies such as pollen allergies and skin itching. Did you know that antihistamines are divided into "first generation" and "second generation" due to their characteristics? This time, we will explain the characteristics of antihistamines, how to choose, and anti-allergy measures.

Characteristics and Selection of Antihistamines

How do antihistamines suppress allergic symptoms?

Allergic symptoms are caused by allergens such as pollen and dust sticking to cells and releasing a substance called histamine. Antihistamines improve allergic symptoms such as sneezing, runny nose, and urticaria by inhibiting the action of released histamine.

I heard that there are first and second generations of antihistamines. Please tell me the difference between each.

The first-generation antihistamine was used, and as it had a strong effect, side effects such as drowsiness and dry mouth were also strong. So the second-generation antihistamine is designed to prevent drowsiness and thirst. The second generation of pollen allergy drugs currently on the market are the mainstream because they are not only difficult to produce side effects but also have advantages such as continuing effects.

Should I use the second generation?

First-generation antihistamines have strong side effects such as drowsiness, but they have the advantage of being effective immediately. If the symptoms are strong and you want to stop right now, the first-generation antihistamine is suitable. Second-generation antihistamines have fewer side effects such as drowsiness and thirst, so if you are worried about side effects, it is recommended to use second-generation antihistamines.

Be careful when taking antihistamines

What are the side effects of taking medicine?

Drowsiness can occur or deteriorate without knowing the judgment or action of 'imbored performance'. In addition, people with prostate hypertrophy or glaucoma may suffer from worsening symptoms such as poor urine or poor eyesight with antihistamines. Depending on the medicine, there are precautions saying, "Do not use it if you have prostate hypertrophy or glaucoma." Please check and take it.

Why do you feel drowsy or have a bare performance?

Antihistamines inhibit the action of histamine and improve symptoms such as runny nose and sneezing. Histamine not only causes allergic symptoms but also improves concentration and learning ability. As the function of histamine is weakened by taking medicine, sleepiness and concentration decrease.

Please let me know what I should be careful about when using antihistamines.

Let's not drive a car because it's easy to get sleepy. In some cases, your judgment may deteriorate without noticing as above. Let's use something that doesn't make you sleepy when you drive a car on a daily basis. It is also effective to take measures such as taking them after driving and being careful about the timing of taking them until the next driving.

What can you do to prevent allergies such as pollen allergies?

I heard that it's better to take hay fever as soon as possible, is that true?

You can suppress the symptoms from getting worse by taking medicine before symptoms of hay fever appear. This is called initial therapy and what can be used in early therapy is a second-generation antihistamine. If you don't know what medicine to use, consult a doctor or pharmacist.

Is there any other way to improve the symptoms besides medicine?

Symptoms can be alleviated by avoiding or avoiding allergen contact. For example, in the case of pollen allergies, they can shake off pollen on clothes or protect it from pollen with a mask or glasses. If you are allergic to house dust, cleaning, ventilation, and using an air purifier are effective.

What should I do if I don't know the allergen?

You can check your allergen through blood tests at hospitals or clinics. A test called View 39 can check for allergens among 39 items, including pollen, house dust, animals, and food.

Even if you take commercial medicine and take measures against allergies, it doesn't improve much....

If your symptoms don't improve, you should see a doctor. On the market, drugs that suppress histamine are the main drugs, but if they are prescription drugs, anti-allergic drugs and steroids that suppress allergies are also included in the options. You will be able to get more optimal treatment because you choose the right medicine according to the severity.

arrangement

Antihistamines have "first generation" and "second generation," indicating that their effects vary depending on the type. When choosing a medicine, it is important to consider the strength of sleepiness, the effectiveness of the medicine, and diseases during treatment. Please be aware of not touching allergens along with taking medicine and skillfully take countermeasures against allergies.
