What is loratadine?
I believe that many "allergic stars" are no strangers to this
This is a kind of specialized for:
Allergic rhinitis, acute or chronic urticaria,
Allergic conjunctivitis, hay fever
and other antihistamines for allergic skin diseases
recently
The topic #loratadine# rushed to the hot search
Many netizens were puzzled
What happened to my life-saving medicine?
It can take effect within half an hour of consumption
However, it cannot completely block allergies
Recently, catkins have been flying
To fight allergies
There are quite a few people when they go out
Always have loratadine on your body
Loratadine is widely popular
This is because it works within half an hour of taking it
It immediately relieves the body's allergic reactions
Why does it work?
▼
Wang Huiying, chief physician of the Department of Allergy of the Second Hospital of Zhejiang University, said that when our body has an allergic reaction to allergens (such as pollen, dust mites, etc.), it will release a chemical called histamine, which binds to specific immune cells and triggers typical allergy symptoms such as itching, runny nose or sneezing. Loratadine acts as an antihistamine and can help the body reduce histamine release, which can alleviate symptoms.
After some netizens saw that loratadine was on the hot search on Weibo, they left a message saying: "My life-saving medicine is on the hot search, and I take loratadine for less than 1,000 yuan every year, and the medicine will not leave my hand." I suddenly decided today that I would not be taboo or pay attention to it in the future, but I would like to see how precious my body is. ”
The practice of not tabooing and not carrying out standardized treatment
Is it feasible?

Director Wang said that the side effects of loratadine are actually very few, and if it is symptomatic, it is no problem to temporarily use it to help relieve symptoms, but it cannot completely block allergies. Contraindication and long-term standardized treatment are aimed at the cause and can fundamentally solve the problem of allergies.
Cetirizine and loratadine
What's the difference, exactly?
Except loratadine
Many netizens pointed out in the Weibo comment area
"Cetirizine" can also be anti-allergic
This also caused some netizens to wonder
Loratadine and cetirizine are two medicines
What's the difference?
What do I need to pay attention to when taking medication?
Cetirizine and loratadine are both commonly used second-generation antihistamines, but they are different classes of compounds, although there is not much difference in efficacy and safety.
There have been some small studies that have found that cetirizine improves symptoms better than loratadine in allergic rhinitis and mosquito bite relief treatments, but is more likely to have sedative effects (such as drowsiness) than loratadine.
There are no data to suggest which drug is more effective for acute urticaria, and several studies of chronic urticaria suggest that cetirizine and levocetirizine may be slightly more effective than other agents.
How to choose different antihistamines?
Do not take while driving!
In fact, the development of antihistamines has also undergone some evolution: from first-generation antihistamines such as chlorpheniramine (chlorpheniramine) to second-generation loratadine and cetirizine, and now there is a third-generation fexofenadine. How do allergic people choose the right antihistamine for themselves?
Director Wang said that loratadine and fexofenadine are metabolized by the liver, and cetirizine is metabolized by the kidneys. Cetirizine is recommended if liver function is poor, and loratadine and fexofenadine are recommended if renal function is poor. Different drugs have different adverse reactions, drug conflicts and applicable populations, please follow your doctor's advice on which one to choose.
Many netizens also mentioned that they were very drowsy after taking loratadine, and they felt very sleepy not long after taking it. Director Wang said that whether there is a drowsiness reaction depends on individual differences, and each person's situation is different. But it is advisable not to take antihistamines when you are going to drive.
