Urinary hesitancy and retention during treatment with sertraline

Urinary retention triggered by dimenhydrinate: A case report

The antihistamine dimenhydrinate as the trigger of acute urinary retention has not been reported. A 35-year-old female with a long-term history of depression treated with sertraline (150 mg/d) since years developed acute urinary retention after having received 100 mg dimenhydrinate intravenously for excessive, postural vertigo. Urinary retention required placement of a disposable catheter, which halted 1.6 liter of urine. Since urinary retention persisted, she received a permanent catheter, which initially halted another 1.2 liter of urine. Urinary retention resolved spontaneously within 48 hours, and the patient was discharged with her previous medication. This case shows that intravenous dimenhydrinate can trigger the development of acute urinary retention in patients under long-term treatment with sertraline, which is why it should be given with caution in this group of patients.

The anxiolytic sertraline reduces the impact of psychological stress on bladder function in mice

AIMS

To determine if treatment with the selective serotonin reuptake inhibitor (SSRI) sertraline reduces the bladder dysfunction caused by water avoidance stress in mice.

MAIN METHODS

Adult female mice were randomly allocated to (1) Unstressed, (2) Stressed or (3) Stress + Sertraline experimental groups. Stressed mice were subjected to water avoidance for 1 h/day for 10 days and received sertraline or vehicle in drinking water, starting 10-days prior to the first stress exposure. Age matched control/unstressed mice were house under normal conditions without stress exposure. Voiding behaviour was assessed throughout the experimental protocol. After the final stress exposure, a blood sample was taken to measure plasma corticosterone levels and bladders were removed, catheterised and intravesical pressure responses recorded during distension and in response to pharmacological agents.

KEY FINDINGS

Plasma corticosterone levels in sertraline-treated animals were equivalent to unstressed controls and significantly decreased compared to the stressed group. Voiding frequency was significantly increased in the stressed group, and treatment with sertraline significantly decreased voiding frequency, however, this remained elevated compared to unstressed control animals. Bladders from stressed mice displayed enhanced maximal contractile response to the muscarinic agonist carbachol and greater release of ACh in the serosal fluid, which was reduced to control levels by sertraline treatment. Spontaneous phasic contractions were not altered by stress but were significantly reduced in bladders from sertraline treated animals, relative to controls.

SIGNIFICANCE

These results indicate that management of voiding dysfunction caused by psychological stress may be aided by the addition of an SSRI such as sertraline.

Serotonin syndrome presenting as surgical emergency: A report of two cases

Serotonin syndrome (SS) is an iatrogenic, drug-induced clinical syndrome caused by serotoninergic hyperstimulation. The diagnosis of SS is easily overlooked as most physicians (up to 85%) are unaware of this syndrome as a clinical entity. Diagnosis is also difficult due to its protean manifestations which can mimic a variety of medical conditions. Herein, we describe two cases of SS, who initially presented to the Surgical Department as surgical emergencies. The first case developed urinary retention after the administration of sertraline. The second case developed features mimicking acute intestinal obstruction. Both cases responded to the removal of offending agents and administration of cyproheptadine. There is a need to increase the awareness of SS among physicians because of the widespread use of serotonergic agents all around the world.

A review of antidepressant-induced urinary hesitancy: a focus on levomilnacipran ER including two case presentations(5633)

INTRODUCTION

Levomilnacipran ER was recently FDA approved as Fetzima® for the treatment of MDD. Urinary hesitancy can be an adverse event associated with levomilnacipran treatment.

AREAS COVERED

This manuscript details the longitudinal course of levomilnacipran-induced urinary hesitancy in 2 cases that were in a pivotal clinical trial, examining possible predisposing factors and treatment issues. This manuscript also reviews the literature comparing urinary hesitancy associated with levomilnacipran versus other antidepressants. Antidepressants that are potent norepinephrine reuptake inhibitors like levomilnacipran, may have increased rates of associated urinary hesitancy. The latter can cause significant discomfort and a compromised quality of life. Occasionally, it can progress to urinary retention necessitating an emergency medical intervention.

EXPERT OPINION

All patients being treated with antidepressants should be carefully monitored for this side effect. Discontinuation of treatment or reduction of the dose of antidepressant frequently relieves urinary hesitancy; alternatively, treatment with an alpha1A antagonist, e.g., tamsulosin may relieve antidepressant-induced urinary hesitancy within hours to days; such strategies allow for continued antidepressant treatment without urinary hesitancy recurring. Thus, with appropriate clinical care, the benefits using levomilnacipran outweigh its risks.

Linking the evidence between urinary retention and antipsychotic or antidepressant drugs: A systematic review

AIMS

Urinary retention (UR) occurs in patients on antipsychotic and antidepressant medication despite no apparent underlying urological cause. This review was undertaken to ascertain which of these medications are associated with UR and how often.

METHODS

A systematic literature search for evidence on antipsychotic and antidepressant medications and UR was completed in June 2015 using Scopus, Pubmed, Web of Science, and the Cochrane library. Search terms included urinary retention, antidepressants and antipsychotics as well as individual drug names. Filters used were: humans and English language. PRISMA guidelines were employed.

RESULTS

Out of 614 articles initially identified, one meta-analysis, five RCT's, five cohort studies and 27 case reports were finally included. There was a wide range of definitions of UR. Studies which appropriately defined UR revealed it occurred in 1/21 patients on ziprasidone (an atypical antipsychotic), 17.6% of those on imipramine but only 0.1% of those on all tricyclic antidepressants analysed together. It was not reported in any of the 1,139 patients given duloxetine (a combined serotonin and noradrenaline reuptake inhibitor). It was reported in 0.025% of patients on selective serotonin reuptake inhibitors. UR was also reported in patients on typical antispychotics, selective noradrenaline reuptake inhibitors but the studies did not define UR. The majority of case reports reported an improvement in UR on discontinuation or dose reduction.

CONCLUSION

Antipsychotics and antidepressants interact with the urinary system in many ways. Clinicians treating acute UR need to keep in mind the role of antipsychotic and antidepressants as a precipitating cause. Neurourol. Urodynam. 35:866-874, 2016. © 2015 Wiley Periodicals, Inc.

Escitalopram-associated acute urinary retention

New-onset urinary retention can typically be explained by the use of the routine normally suspected medications (e.g., anticholinergics, antihistamines). However, selective serotonin-reuptake inhibitors are not typically presumed as the cause of acute urinary retention (AUR). The following case describes the introduction of escitalopram in a patient and the subsequent development of AUR. Medical causes of urinary retention had been ruled out, and ipratropium was initially suspected to be the cause of urinary difficulties and was discontinued. However, the retention persisted four days after suspending the ipratropium. Normal micturition resumed only after stopping the escitalopram without further need for catheterization. Escitalopram may cause rare cases of AUR and may often times be overlooked possibly because of the paucity of reporting.

Are commonly used psychoactive medications associated with lower urinary tract symptoms?

PURPOSE

Lower urinary tract symptoms (LUTS) such as urinary frequency and urgency are bothersome and associated with reduced quality of life. Atypical antipsychotics (AAPs) have been implicated in increasing the risk of urinary incontinence. In a large community-based sample of men and women, we examined the associations of AAP and selective serotonin reuptake inhibitor (SSRIs) use with LUTS.

METHODS

Data were collected (2002-2005) from a generalizable sample of Boston, MA, USA, residents aged 30-79 (N = 5503). LUTS were assessed using the American Urologic Association Symptom Index (AUA-SI). The prevalence of clinically-significant LUTS was estimated using a cutoff AUA-SI score of 8+ to indicate moderate-to-severe symptoms. Confounder-adjusted odds ratios (ORs) and 95% confidence intervals (CI) were calculated from multivariate logistic regression to estimate the associations for psychoactive drugs used in the previous month (SSRIs, AAPs, both) and LUTS.

RESULTS

Among women, AAP users had a higher prevalence of LUTS (46.2%) compared with SSRI users (23.5%) and those with depressive symptoms not using SSRIs or AAPs (26.3%). Corresponding prevalence estimates among men were 32.7%, 29.8%, and 33.3%. In multivariate models, AAP use was significantly associated with LUTS among women when used either with (OR = 2.72, 95% CI:1.45-5.10) or without (OR = 3.05, 95% CI:1.30-7.16) SSRIs, but SSRI use without AAP use was not associated with LUTS compared with nonusers without depressive symptoms. No associations were observed among men.

CONCLUSIONS

In our study, AAPs but not SSRIs were associated with increased prevalence of LUTS among women only. Further prospective research is needed to determine time sequence and cause and effect.

Female voiding dysfunction: prevalence and common associations

The understanding of voiding dysfunction has been greatly assisted by the current introduction of clear definitions for its diagnosis and for the abnormalities of urine flow rates and postvoid residuals that are its basis. Its prevalence in women with symptoms of pelvic floor dysfunction is up to 40%. Most of the recent research has centered on the associations of voiding dysfunction with age, pelvic organ prolapse, and prior continence surgery. The effects of parity, medications, and pelvic tumors have also been explored.
