What are the symptoms of drug allergy when taking an intravenous drip?

Symptoms of drug allergies: a. Drug eruption, that is, drug dermatitis, is a drug reaction with the eruption of the mucous membrane as the main manifestation, and it is a major component of drug allergy.

Two. Anaphylactic Diseases: 1

Anaphylactic shock: This is a severe and critical allergic reaction to a drug, often manifested by dyspnea, circulatory failure, and coma, sometimes life-threatening. Such as penicillin-induced anaphylactic shock.

2.Blood-like reactions: are drug-induced hematologic abnormalities, including granular leukopenia or deficiency, aplastic anemia, and thrombocytopenia.

3.Serum sickness-like reactions: usually manifested as fever, joint swelling and pain, "rubella" on **, swollen lymph nodes, and sometimes myocardial damage.

4.Hepatitis-like reactions: most of the manifestations are jaundice, liver dysfunction, elevated aminotransferases, often accompanied by fever and rash, most of the disease can be reversed, and severe patients can develop acute liver necrosis.

5.Drug fever: is fever caused by a drug reaction and in many cases is the only systemic symptom.

Sometimes fever is present without rash, and it is difficult to distinguish for a while. 6.Other reactions:

Drug allergies can also cause asthma, induce or aggravate lupus erythematosus, or damage important organs such as the heart, kidneys, and central nervous system, as well as vital organs such as the eyes, eyes, and ears.

Cramps in the hands and feet, chest tightness and discomfort, paleness, itching, long grains, rubella, severe allergic reactions can kill people. It is recommended that if there is discomfort or similar symptoms during the drip, the needle must be removed for a while, the infusion should be stopped, and the next visit should also clearly tell the doctor what drugs you have used before, and what symptoms you have had before, so as to cure your disease as quickly and effectively as possible for your safety.

Depending on what the allergy is, the allergic reaction to each drug is different.

The medical advice you provided is very irregular, and I can't say anything about it, but according to your description, your son should have had laryngeal edema caused by a drug allergy, so he had difficulty breathing, not an infusion reaction.

As for responsibility, as long as the doctor rescued in a timely manner and handled it properly, the hospital did not need to be responsible. (e.g., changing fluids, replacing allergy medications; Dexamethasone intravenously relieves laryngeal edema and reduces dyspnea, etc., which are in place).

Most people don't understand much about doing a skin test, but in fact, the skin test is just a primary gatekeeper, and a negative skin test does not necessarily mean that there will be no allergies when taking the drug, and there may also be a delayed reaction, which is a situation that may occur with many drugs, but the severity is different, and your son's situation is obviously heavier. And if the skin test is positive, of course, it is even more unlikely to take medication. For the same person, for the same drug, the skin test results will also be different according to different batch numbers and different physical states.

Therefore, the results of the skin test have reference value for predicting anaphylactic shock reactions, so the results can be used only if the results are negative, but it should be noted that some patients will have a false negative reaction (that is, in your case, the skin test has nothing to do with the infusion), and a small number of people can have severe allergic reactions during the ** test (this is more unlucky, and a strong reaction occurs during the skin test).

ps：1.I haven't seen your son's original medical advice, and I don't comment on what you wrote.

2.Your family**, I haven't heard of the method you said about doing a skin test. I'm sorry, but I'm from a ravine. It's okay to do it just once.
