Hi,How many use Sensipar? Have you had problems?Before starting NxStage the doctors tried to put my husband on Sensipar twice. He started this and then I saw on the Sensipar site their safety notice. We then refused to take it since his calcium was never higher than 8.3 (usually lower). The "for health professional" part of their site has the following warning.Important Safety InformationSensipar® lowers serum calcium; therefore, it is important that patients have a serum calcium ≥ 8.4 mg/dL when initiating therapy. Significant reductions in calcium may lower the threshold for seizures. Secondary hyperparathyroidism patients, particularly those with a history of a seizure disorder, should be carefully monitored for the occurrence of low serum calcium or symptoms of hypocalcemia. The most commonly reported side effects were nausea and vomiting. The doctors said to ignore this. I am wondering what results others have had using Sensipar.RoadrunnerEDITED: Fixed topic title error-kitkatz,moderator
