A voluntary nationwide recall of 3 different lots of the antidepressant venlafaxine (Effexor, Pfizer Inc) has been issued by the drug’s manufacturer owing to possible contamination with a heart drug and subsequent potentially fatal consequences.
As a precaution, Pfizer Inc is recalling 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.
According to Pfizer, the action is being taken because 1 bottle of Effexor XR contained a single capsule of dofetilide (Tikosyn, Pfizer Inc) 0.25 mg, an antiarrhythimic medication used to treat atrial fibrillation/atrial flutter and maintain normal sinus rhythm.
Pfizer says the probability that other bottles of Effexor XR have been similarly contaminated is low but that it has issued the recall as a precaution.
This recall involves Pfizer lot numbers V130142 and V130140, which both expire in October 2015, and Greenstone lot number V130014, which expires in August 2015.
