Venlafaxine alprazolam

Pregabalin produced anxiolytic effects similar to lorazepam, alprazolam, and venlafaxine in acute trials. Sedation and dizziness were the most common adverse effects, and the dose should be tapered over 1 week upon discontinuation.

A metaanalysis showed that SSRIs, TCAs, and CBT are similarly effective. Alprazolam, clonazepam, sertraline, paroxetine, and venlafaxine are... 

The effects of venlafaxine on the pharmacokinetics of alprazolam have been investigated in 16 healthy volunteers. Steady-state venlafaxine 75 mg bd did not inhibit CYP3A4 metabolism of a single dose of alprazolam 2 mg (33).

Single-dose venlafaxine does not alter the single-dose pharmacokinetic profile of drugs metabolized by CYP3A4 (alprazolam and diazepam). When milnacipran was administered with lorazepam in healthy volunteers, no changes in the pharmacokinetics of any drug were detected. 

Alprazolam at a daily dose of 0.25 mg twice a day up to 0.5 mg three times a day during the luteal phase or buspirone at continuous dosing are considered second-line treatment. Venlafaxine has also been reported to exert significant efficacy at doses of 50-200 mg/day. 

Fluvoxamine inhibits liver drug-metabolizing enzymes. Dosages of alprazolam, theophylline, and warfarin must be reduced if any of these drugs are given concomitantly with fluvoxamine. Nefazodone may also decrease the metabolism of benzodiazepines, and venlafaxine may inhibit haloperidol metabolism. The answer is (B). 

Visual hallucinations have been seen in one patient given zolpidem and venlafaxine. No important interaction normally appears to occur between venlafaxine and alprazolam or diazepam. The pharmacokinetics of duloxetine were not affected by lorazepam or temazepam. 

The studies suggest that no special precautions are necessary during the concurrent use of venlafaxine and diazepam or alprazolam, or between duloxetine and lorazepam or temazepam. Similarly, the manufacturer of duloxetine reports that its pharmacokinetics were not affected by lorazepam or temazepam under steady state conditions. ... 

Venlafaxine can increase the serum levels of haloperidol. This is consistent with an isolated report, which describes a man who developed urinary retention when venlafaxine was added to a previously well-tolerated regimen of haloperidol and alprazolam. 

A study in 24 healthy subjects found that steady-state venlafaxine 75 mg every 12 hours reduced the renal clearance of a single 2-mg dose of haloperidol by 42%, resulting in a 70% rise in the AUC and an 88% rise in its maximum serum levels. " This rise in haloperidol levels would seem to be consistent with an isolated report of a 75-year-old man taking haloperidol 1 mg and alprazolam 500 micrograms daily, who suddenly developed urinary retention when venlafaxine 37.5 mg daily was added.
