Pharmaceutical company Pfizer, Inc. has announced a voluntary recall of the antidepressant drug Effexor XR (venlafaxine HCI).

The recall affects 1 lot of 30-count Effexor XR (venlafaxine HCI) 150 mg extended-release capsules, 1 lot of 90-count Effexor XR (venlafaxine HCl) 150 mg extended-release capsules, and 1 lot of 90-count Greenstone LLC-branded venlafaxine HCl 150 mg extended-release capsules.

Lot numbers in the recall are: Pfizer V130142 and V130140 expiring in October, 2015 and Greenstone V130014 expiring in August, 2015.

Pfizer says the action is being taken due to a report from a pharmacist that one bottle of Effexor XR contained a single capsule of the antiarrhthmic medication Tykosin.

“The use of Tikosyn by an Effexor XR/Venlafaxine HCl patient, where the contraindications and drug-drug interactions with Tikosyn have not been considered by the prescribing physician, could cause serious adverse health consequences that could be fatal,” according to the Pfizer press release.

For questions regarding the recall, consumers can call Pfizer Medical Information at 1-800-438-1985.
