The recall affects 30-count and 90-count bottles of Effexor XR 150-milligram extended release capsules and 90-count bottles of Greenstone-branded Venlafaxine 150-milligram extended release capsules.
According to a press release, a pharmacist had reported that a bottle of Pfizer's Effexor XR contained one capsule of Tikosyn. There have been no other reports, but three lots that were packaged on the same line are being voluntarily recalled as a precaution.
The use of Tikosyn by someone taking Effexor or Venlafaxine could have "serious adverse health consequences that could be fatal," the press release states.
Patients should watch out for signs of abnormal heartbeat and contact their doctors if they have any problems.
