Similarly, the dose should be reduced by half in those taking strong CYP2D6 inhibitors. Vortioxetine can be discontinued abruptly without tapering, but it is recommended that at doses of 15 to 20 mg/day it be tapered first to 10 mg/day one week prior to full discontinuation if possible. Available forms
Vortioxetine is available in the form of 5, 10, and 20 mg immediate-release, film-coated oral tablets. Contraindications
Vortioxetine is contraindicated in those with hypersensitivity to vortioxetine or to any other components of vortioxetine tablets. It is also contraindicated in those taking monoamine oxidase inhibitors (MAOIs) due to the possibility of serotonin syndrome. Adverse effects
The most common side effects reported with vortioxetine are nausea, vomiting, constipation, and sexual dysfunction, among others. With the exceptions of nausea and sexual dysfunction, these side effects were reported by less than or equal to 10% of study participants given vortioxetine. Significant percentages of placebo-treated participants also report these side effects. Discontinuation of treatment due to adverse effects in clinical trials was 8% with vortioxetine versus 3% with placebo.Sexual dysfunction, such as decreased libido, abnormal orgasm, delayed ejaculation, and erectile dysfunction, are well-known side effects of SSRIs and serotonin–norepinephrine reuptake inhibitors (SNRIs). In clinical trials, sexual dysfunction occurred more often with vortioxetine than with placebo and appeared to be dose-dependent. The specific incidences of treatment-emergent sexual dysfunction as measured with the Arizona Sexual Experience Scale (ASEX) were 14 to 20% for placebo and 16 to 34% for vortioxetine over a dosage range of 5 to 20 mg/day.
There is also interest in vortioxetine for the potential treatment of social phobia, neuropathic pain, and for cognitive enhancement in major depression. References
