I receive enzyme replacement therapy (an orphan drug) for a super rare disorder called gaucher disease.I get home infusions and use the iflow 400ml/100ml per hour pump (lot #0202219871).I receive ert every two weeks.My past infusion on (b)(6) 2015 the iflow malfunctioned.The pump stopped flowing leaving about 75% of my drug in it.Not having my full dose of drug has negative effects on my symptoms including bone pain and chronic debilitating fatigue.
