What Is Venlafaxine?
Venlafaxine is a prescription medication. It was approved by the U.S. Food and Drug Administration (FDA) in 1993. It was first developed by Wyeth Pharmaceuticals Inc., which was eventually bought by Pfizer. Except for the common use of Effexor for anxiety and major depressive disorder, it can also be used for generalized anxiety disorder, panic disorder, and social anxiety disorder.
Venlafaxine ER vs. Venlafaxine IR
Oral tablets of the venlafaxine trade name may be available in immediate-release (IR), and extended-release (ER) formulations in the tablets form only.
What are venlafaxine ER tablets? Venlafaxine HCl ER is an extended-release formulation of the drug. Venlafaxine HCL ER has fewer side effects than venlafaxine brand name; however, it has no advantage over immediate-release formulation in reducing Effexor withdrawal effects. Effexor half-life of the immediate-release formulation is five hours. While the extended-release formulation half-life is about 12 hours. Effexor cost is usually cheaper in immediate-release than extended-release formulation.
What is Effexor XR drug? Effexor XR is the sustained-released form of venlafaxine hydrochloride. Effexor XR capsules are only available as extended-release formulation. Effexor XR is characterized by extending the plasma-concentration time of the drug (while venlafaxine IR formulation usually takes about 4 to 6 weeks to appear its effects).
Why has Effexor been discontinued in the US? The original formula of Effexor was discontinued from the U.S. market because it was required for the patient to take 2 to 3 doses daily, while Effexor XR can be taken once daily. Moreover, Effexor XR causes less nausea than the original formula.
The plaintiffs continued to used Effexor during pregnancy. As a result, the plaintiff’s daughter Adelaide was born with severe cardiac defects due to Effexor use during pregnancy. The fatal malformations led to death after a girl was born by a few hours. Plaintiffs in venlafaxine lawsuits have claimed that Pfizer didn’t warn patients about the risks of birth defects. Since then, two more Effexor lawsuits against Pfizer for birth defects have been filed.
Venlafaxine also increases suicidal thinking among people under the age of 24. For this reason, it is not recommended to use it for younger patients. Several Effexor XR class-action lawsuits against the company were done. Effexor class-action lawsuits are being filed by those who were harmed either due to congenital disabilities or suicidal thoughts. These patients may be eligible to receive an Effexor lawsuit settlement from Pfizer.
