With the growing number of types of drugs, the occurrence of drug allergies who was also a growing trend. Had occurred once drug allergies, if you do not pay attention, it is prone second drug allergies. The second drug allergy symptoms, not only a serious than the first, but also may occur exfoliative dermatitis , epidermolysis bullosa psychosis serious life-threatening situation.
If you are allergic to a particular drug is known whether the future as long as the drug is no longer used, you can avoid a second drug allergies out? It is not. Because there is still a cross-allergy drug problem.
The so-called cross-allergy drug, refers to a particular drug, the patient has an allergic reaction occurs, another drug used later, although the first occurrence of drug allergy is different, but the first occurrence of allergy drug similar in chemical structure, it will also Drug hypersensitivity reactions occur.
If the patient has undergone some kind of allergy to sulfa drugs, other iodine amine drugs can not be used. Also note that some of the drugs, although not a sulfa, but may make people allergic to sulfa allergy cross appeared, such as sulfonylurea oral metformin drop, tolbutamide tablets, chlorpropamide tablets blood sugar drugs. Sulfa drugs containing a chemical group - right aminobenzenesulfonamide, these drugs also contain amino benzene sulfonamide group, it will happen cross-allergy drugs.
In another example, a patient has been sent and had penicillin allergy, it would not use amoxicillin capsules and other drugs. Cephalosporins in the chemical structure of penicillin drugs similarities. So, when using cephradine capsules or injections, ceftriaxone, Pioneer risperidone and other cephalosporins may occur when cross-allergy drug.
Common cross-allergy medications are:
promethazine, chlorpromazine, perphenazine, trifluoperazine and other phenothiazine antipsychotics cross allergies.
Erythromycin and Midecamycin cross, spiramycin and other macrolides cross allergy.
Tetracycline and minocycline, doxycycline and other drugs cross allergy.
Gentamicin and kanamycin, amikacin, tobramycin and other aminoglycoside antibiotics than cross allergies.
Also note that, to avoid cross-allergy drugs, in addition to taking care to avoid the use of chemical structure similar drugs, but also to avoid the use of the same drug-containing serum protein preparations. For example, injection of tetanus antitoxin allergic patients can not be used in future rabies serum injections, because these two drugs, contain serum proteins horses. Patients allergic to these drugs occurred, mostly for such drugs in animals horse serum protein allergy.
In addition to the two aspects mentioned above, the occurrence of drug allergies, but also to avoid the use of the first allergy medicines containing the same compound preparation.
