If the mechanism is fairly focused but the dosing schedule is poorly chosen, the observed effects may reflect protocol strain, cumulative exposure patterns, or handling inconsistencies rather than the peptides intended pharmacology
Administration routes vary: subcutaneous injections for systemic peptides, oral forms when bioavailability allows, and topical or intra-vaginal formulations when local delivery reduces systemic exposure

SJS can occur even without a precipitating medication Infection can set it off especially in patients with risk factors including HIV, lupus, underlying malignancy, and genetic factors SATAN for the most common drugs Sulfa, Allopurinol, Tetracyclines, Anticonvulsants, and NSAIDS Anti-epileptics include carbamazepine, lamictal, phenobarb, and phenytoin Can have a curious course Hypersensitivity reaction can develop while taking medication, or even one to four weeks after exposure In pediatric population, mycoplasma pneumonia and herpes simplex have been identified as precipitating infections Patients often have a prodrome 1-3 days prior to the skin lesions appearing May complain of fever, myalgias, headaches, URI symptoms, and malaise Rash may be the sole complaint Starts as dark purple or erythematous lesions with purpuric centers that progress to bullae Skin surrounding the lesions detaches from the dermis with just light pressure (Nikolsky Sign) Up to 95% of patients will have mucous membrane lesions ~85% will have conjunctival lesions Symptoms: Burning or itching eyes, a cough or sore throat, pain with eating, pain with urinating or defecating Source: JAMA Dermatol
