What is Jornay PM?
Jornay PM is a brand name for a specific extended-release formulation of venlafaxine hydrochloride, designed for once-daily administration [1]. It is prescribed for the treatment of major depressive disorder [1]. The "PM" in its name indicates that it is intended to be taken in the evening.
How does Jornay PM work?
Jornay PM contains venlafaxine, which is a serotonin-norepinephrine reuptake inhibitor (SNRI). It works by increasing the levels of serotonin and norepinephrine in the brain, which are neurotransmitters thought to play a role in mood regulation [1]. The extended-release formulation is designed to gradually release the medication over a 24-hour period, providing a more consistent therapeutic effect [1].
What are the uses for venlafaxine extended-release?
Venlafaxine extended-release, including formulations like Jornay PM, is primarily used to treat major depressive disorder [1]. It may also be prescribed for other conditions, such as generalized anxiety disorder, social anxiety disorder, and panic disorder, depending on the specific formulation and prescribing physician's judgment [1].
What are common side effects of venlafaxine extended-release?
Common side effects associated with venlafaxine extended-release formulations can include nausea, dry mouth, insomnia, somnolence, dizziness, and sweating [1]. Patients should consult with their healthcare provider for a complete list of potential side effects and to discuss any concerns [1].
Can other companies make generic versions of venlafaxine extended-release?
Once patents and exclusivity periods expire, other pharmaceutical companies can seek approval to manufacture and market generic versions of venlafaxine extended-release [2]. The availability of generic versions can increase accessibility and potentially lower costs for patients.
