![]() ![]() From there, they can evaluate if a corticosteroid injection is safe for the treatment of your TMJ symptoms. Nevertheless, there are reports inter-group cross-reactivity so caution is always advised.įortunately, your doctor can do allergy testing to confirm whether or not you have an allergy to a specific drug. Type B reactions, which account for the remaining 20, are subdivided into the far more frequent cross-reactive, non-immunological NSAID-HS (acronyms NERD NSAID exacerbated respiratory disease, NECD NSAID exacerbated cutaneous disease, NIUA NSAID-induced urticaria/angioedema) and the much rarer true drug allergies of type I and IV. 24 The rate of cross-reactivity between aminopenicillins and aminocephalosporins has been reported to be as high as 3040 in predominately European studies. Hydrocortisone and triamcinolone are classified in different groups, A and B respectively. Cross-reactivity is particularly seen with aminopenicillins (amoxicillin, ampicillin) and aminocephalosporins (cefalexin, cefaclor, cefadroxil, ceprozil). Topical corticosteroids are classified by strength and the risk of adverse effects such as atrophy, striae, rosacea, telangiectasias, purpura, and other cutaneous and systemic reactions. this was not counted as a long-term dosage increase. You are more likely to be allergic to corticosteroids in the same group. Cross-reactivity of both endogenous and exogenous corticosteroids has been. For example, the following corticosteroids are classified in Group A: A,B,C and D) based on their chemical structure. Most studies classify corticosteroids in groups (e.g. There have been a few studies that evaluated corticosteroid cross-reactivity. In general, medications in the same class should be avoided if possible, due to the chance that an individual allergic to one drug within the class might also have an allergic reaction to other drug with a similar chemical structure. Nevertheless, the chemical structure of triamcinolone and hydrocortisone are similar and there is a chance of cross-reactivity in terms of allergies. Triamcinolone, like hydrocortisone, is classified as a corticosteroid but is chemically different. One of the most commonly used corticosteroids for TMJ is triamcinolone. However, you will want to let your doctor know about the reaction you had to hydrocortisone so you can be appropriately evaluated. Answerīeing allergic to hydrocortisone doesn't necessarily mean that you will be allergic to other corticosteroids, such as the ones that given via injection for the treatment of pain associated with TMJ (temporomandibular joint disorders). If you got a rash from hydrocortisone cream 2.5mg on your hands, can you get a steroid shot in your jaw for TMJ symptoms? Thank you.
