Allergies are a common phenomenon that many people have experienced, such as food allergies, pollen allergies …… but actually did you know? Drug allergy is also one of them. Generally speaking, drug allergy refers to some allergic reactions that occur when using commonly used or lower than commonly used amount of drugs, which may cause itchy skin, rash, fever in mild cases, or even life threatening anaphylaxis in severe cases.


Why do drug allergies occur?


The causes and mechanisms of allergies are generally complex and varied, and drug allergies are the same. For example, the same drug, such as aspirin, can cause severe allergic reactions in some people, while others do not experience any discomfort after using it. This is actually because of the different body types.


These 3 groups of people are prone to drug allergies


1,Long-term users of multiple drugs


In terms of risk, the likelihood of drug allergy is greatly increased for people who take multiple drugs for a long time, and the more types of drugs they take, the more likely it is to cause drug allergy.


2,People with allergies


There are two types of allergic people, one is congenital, i.e., acquired through heredity, and the other is acquired, caused by the excess and deficiency of various endocrine hormones or enzymes in the body, as well as the imbalance between hormones or enzymes. Both of these allergies are the most important internal causes of drug allergy.


3,People who are frequently exposed to drugs


Health care workers in pharmacies, hospital pharmacies, and workers in pharmaceutical companies and factories are often exposed to drugs and often inhale drug volatiles or dust, so the chance of drug allergy increases accordingly.

How to prevent drug allergy?


Medication under the guidance of a physician


It is often said that “medicine is three parts poison”, which is not without reason. If you need to use drugs, it is best to do so under the guidance of a physician and try to use drugs scientifically, reasonably and safely.


Drug dosage needs to be careful


There is a good saying, “to put aside the dose to talk about toxicity is a rogue”, the right amount, the drug is a life-saving antidote, and once the overdose of drugs, may be a deadly poison. In the process of medication, do not use too many drugs, too chaotic, too mixed, while the dose of drugs should not be too large, the same drug should not be taken for too long.


Pay attention to drug allergies


If you want to stay away from drug allergy, you must first have the awareness and common sense of drug allergy. If you have unexplained fever, rash with itching, or sudden chest tightness, palpitation, dizziness, cold sweat, nausea, vomiting, etc. during the first or second application of the same drug, you should promptly consider drug allergic reactions and ask your doctor to make a diagnosis and treatment.


Stay away from allergic drugs


It is important to keep in mind the drugs to which you are easily allergic to avoid repeated allergies. In addition, since many new drugs are compound preparations or compound preparations of Chinese and Western medicines, it is important to read the instructions carefully before applying these drugs and understand the composition of the drugs to prevent the components of the drugs from containing drugs that have caused allergies before.


At the same time, it is important to pay attention to the cross-allergy and polyvalent allergy phenomenon of drugs. For example, people who are allergic to penicillin. Oral administration of amoxicillin is contraindicated because of the cross-allergy phenomenon between the two.
