QuarterWatch® Reports

Perspectives In This Issue - January 2013

In this QuarterWatch™ report, we analyze a signal for persistent sexual side effects reported by men who have taken finasteride (PROPECIA) for male pattern baldness or for an enlarged prostate (PROSCAR).

We also review product problems with the DAYTRANA methylphenidate patch used in young children to treat ADHD.

In addition, we update our coverage of anticoagulant drugs with new perspectives on adverse events reported for dabigatran (PRADAXA) and rivaroxaban (XARELTO).

QuarterWatch™ is an independent publication of the Institute for Safe Medication Practices (ISMP). We analyze computer excerpts from the US Food and Drug Administration (FDA) Adverse Event Reporting System (FAERS). These reports (best known as MedWatch reports) are a cornerstone of the nation’s system for monitoring the safety of prescription drugs after FDA marketing approval.
