What Are the Most Common Side Effects of Allergy Shots?
Drug allergies, also called drug allergies, are allergic reactions caused by medication (including oral, injection and topical topical medications). There are two necessary factors for the development of drug allergies: allergies and exposure to drugs.
Drug allergy
- Drug allergy is also called
- Drug allergy is also called
- The clinical manifestations of drug-induced allergies are diverse and can belong to any type of allergies, and in many cases are a combination of polymorphic allergies.
- (1) Drug fever. The fever caused by a drug allergy is called drug fever, and it is often the earliest manifestation of a drug allergy. Drug fever is different from general infectious fever. If it is the first time, fever can occur after a sensitization period of about 10 days; if it is re-administered, the fever can occur quickly because the human body has been sensitized. Drug fever is generally a persistent high fever, often reaching 39 degrees or even 40 degrees or more.
- (2) Drug rash. Drug allergies can often cause a rash, which we call a drug rash. Drug rashes usually follow drug fever, but they can occur before drug fever. The rash can take many forms, such as measles-like, scarlet-like, eczema-like, urticaria-like, purpuric-like, herpes-like, etc.
- (3) Serum disease-like reactions. Serum disease is an allergic reaction that occurs after the first application of serum (such as horse serum) in about 10 days. Clinical manifestations include fever, lymphadenopathy, joint swelling and pain, and liver and spleen enlargement.
- (4) Other systemic damage. Severe drug allergic reactions can cause systemic damage such as anaphylactic shock, reduced blood cells, hemolytic anemia, etc .; respiratory symptoms such as rhinitis, asthma, alveolitis, etc .; digestive symptoms such as nausea, vomiting, abdominal pain, diarrhea, etc .; liver damage Such as jaundice, bile stagnation, etc .; kidney damage such as hematuria, proteinuria, renal failure; nervous system damage such as migraine, epilepsy, etc.
- (1) Drugs that can cause rashes such as urticaria include: penicillin, streptomycin, sulfa drugs, aspirin, pentamidine, butepine, and barbiturin procaine. Vaccinations, diphtheria and tetanus antitoxins.
- (2) Drugs that can cause angioedema include: penicillin, sulfa drugs, aspirin, butazone, oxytetracycline, chloramphenicol, diethylstilbestrol, vaccination, diphtheria and tetanus antitoxin.
- (3) Drugs that can cause exfoliative dermatitis include: penicillin, streptomycin, sulfa drugs, butapine, barbiturates, diethylstilbestrol, etc.
- (4) The drugs that can cause anaphylactic shock are: epimycins, adrenocorticotropic hormones, oxytetracycline, chloramphenicol, streptomycin and so on.
- Drugs have both therapeutic effects and toxic side effects. The most common is an allergic reaction. The following measures can be taken to prevent drug allergies.
- (1) Strictly control the use of allergenic drugs. There are many clinically susceptible drugs, such as penicillin sodium, streptomycin, lincomycin (infusion), gentamicin (infusion), vitamin gelatin, Bupleurum needles, safflower needles, penetrating needles, Vitamin K, etc. should be strictly controlled for use.
- (2) Prepare rescue drugs before use. Even a drug that has never had an allergic reaction does not mean that it does not occur. People with allergies may be allergic to any medicine. Rescue drugs such as epinephrine, nicosamite, dexamethasone, annaka, and oxygen must be prepared before medication. It is too late to prepare rescue drugs after an allergic reaction occurs.
- (3) Take medicine strictly according to requirements. Read the instructions carefully to fully understand the side effects, precautions, and contraindications of the drug, and strictly follow the medication route and dosage of the drug. Such as vitamin B1 can only be injected intramuscularly, anaphylactic shock will occur when intravenous injection; Shi Ning overdose can cause spasm.
