Medical Video: Miami's Chest Rash? Guess This Rash?
When your allergic reaction recurs, it's not very comfortable, right? The skin becomes itchy, redness, swelling, or feels hot and sore. In addition, allergic reactions that often occur are sneezing, itchy and runny nose, or itchy and runny eyes. At times like this, you certainly need medication to deal with itchy skin, eyes, or nose. At present there are several types of allergic itching drugs in pharmacies, for example cetirizine or loratadine. To understand more about the drug itching due to allergies, see the following review.
How it works for allergic itching drugs
An itchy allergy medication is an antihistamine which functions to relieve allergic symptoms. When you eat or come into contact with allergens that are actually harmless, histamine produced by the body's immune system will overreact. Histamine also commands the body to fight allergens. This is what causes allergic reactions or symptoms, namely the skin, nose, and eyes itch.
To relieve allergic symptoms, itching drugs function to stop or limit histamine activity in the body. However, allergic itching drugs cannot be used to prevent allergic reactions or treat severe allergic reactions such as anaphylactic.
The choice of an itchy drug due to allergies
If your allergies are recurrent, there are now many medicines to treat allergic itching that can be purchased without a doctor's prescription. Here are the most common types of allergic itching drugs.
Cetirizine
Cetirizine is a generic name for second generation antihistamine drugs. This drug can fight allergic symptoms without causing drowsiness. Cetirizine is available in tablets, syrups and drops (drop it) Like most other second generation antihistamines, these drugs only need to be taken once a day or according to the dosage recommended by your doctor or pharmacist.
Loratadine
This itching drug is similar to cetirizine. Loratadine is also a second generation antihistamine drug that does not cause drowsiness and is taken enough once a day. Various studies have revealed that cetirizine and loratadine are equally effective in overcoming allergy symptoms, namely hives. However, for a faster antihistamine effect, cetirizine is still superior to loratadine.
Fexofenadine
Compared to other second generation antihistamine drugs, fexofenadine is the least side effect. According to various surveys conducted by experts, some people still feel sleepy after drinking cetirizine or loratadine. Meanwhile, fexofenadine at least causes drowsiness. However, according to a 2001 study, cetirizine and loratadine were still faster in stopping histamine.
Diphenhydramine
Unlike other itching drugs, diphenhydramine is a first generation antihistamine drug. So, this drug causes drowsiness and weakness. If you want to take this medicine, make sure you are not driving or operating the machine. However, many people report that its efficacy to relieve itching is faster compared to second generation antihistamines.
