We describe here a case of a female patient with a history of diabetes, diabetic neuropathy, and hypertension being prescribed both gabapentin and pregabalin concomitantly which led to adverse effects like drowsiness, dizziness, fatigue, and ataxia. Opioid cross-reactivity is the uncommon occurrence of having an allergic reaction to more than one opioid. Allergies to opioids present a unique challenge in pain management due to the limited The clinical cross-reactivity between the traditional aromatic AEDs, phenobarbital, PHT and CBZ is well known (Hyson and Sadler, 1997). There is less experience with the new generation of antiepileptic agents. The aim of this study was to assess cross-reactivity for skin reactions among current aromatic AEDs, including OXC and LTG. Thus, two-dimensional shape similarity of cross-reacting molecules and the target molecules of TDM immunoassays provides a fast chemoinformatics methods for a priori prediction of potential of cross-reactivity that might be otherwise undetected. This study confirmed the prevalence of neuropsychiatric ADRs associated with gabapentin or pregabalin. A high rate of death occurred with gabapentin in an obstetrical context. Other ASMs showing a high number of pairings with reactions to both medications were phenobarbital, lamotrigine, topiramate, gabapentin, and pregabalin. In general, the aromatic ASMs showed both greater reaction rates alone and with other ASMs at some point. Learn about the potential cross-reactivity between Lyrica and gabapentin and how it can affect patients who are prescribed these medications. The hypersensitivity syndrome is a potentially life-threatening adverse drug reaction with multiorgan involvement, and incidental reexposure must be strictly avoided. Patients and treating physicians must be informed and educated about the causal drug and its potential immunologic or toxicologic cross-reactivity with other compounds. One study analyzed data from phase 2 trials of gabapentin and pregabalin and created a pharmacodynamic model. 3 The authors found that in patients with postherpetic neuralgia, mean pain scores decreased as the dose of both gabapentin and pregabalin increased. Abstract Pregabalin is the first-line treatment for neuropathic pain. Cases of cutaneous hypersensitivity reactions caused by pregabalin generally occur within 2 weeks of initiating medication. We report a rare case of a delayed cutaneous hypersensitivity reaction caused by pregabalin, which was confirmed by a drug provocation test. There is no evidence of cross-reactivity with AEDs in patients with allergies to other aromatic structures such as sulfonamide medications. However, these patients may be more prone to allergic reactions in general. The important potential cross-reactivity between aromatic anticonvulsant and tricyclic antidepressant drugs should be brought to the attention of treating physicians. Prior to pregabalin therapy, the patient indicated that she had taken gabapentin for approximately 3 weeks for the pain, but had discontinued it due to adverse effects and perceived lack of Hypersensitivity syndrome has not been described in patients taking benzodiazepines or the newer anticonvulsants gabapentin or topiramate, and these appear to be safe substitutes for drugs that cause the reaction. Review detailed drug interaction details between Gabapentin and Pregabalin, including severity, interaction details, how to manage the interaction, and more. We study 262205 people who take Cross sensitivity reaction or have Lyrica. No report of Cross sensitivity reaction is found in people who take Lyrica. Using gabapentin together with pregabalin may increase side effects such as dizziness, drowsiness, confusion, and difficulty concentrating. Some people, especially the elderly, may also experience impairment in thinking, judgment, and motor coordination. Once again to your main question, yes, lyrica is contraindicated if you are allergic to gabapentin and you may try one of the other nerve pain pills mentioned above which are safe with gabapentin allergy. Please let me know if you have more questions. In general use, both gabapentin and pregabalin are associated with dose-dependent ADRs, mainly mild-to-moderate and transient in nature. Many recent meta-anal-yses have focused on the ADRs induced by these two drugs. Classical antiepileptic drugs may cause cross-hypersensitivity reactions. 23, 24 However, because of the different chemical structures of gabapentinoids and classic antiepileptic drugs, whether pregabalin and gabapentin have the potential to cause cross-hypersensitivity reactions remains unclear.
