The risks associated with longer-term Venlafaxine hydrochloride extended release capsules use were assessed in an open-label study of children and adolescents who received Venlafaxine hydrochloride extended release capsules for up to six months. The children and adolescents in the study had increases in weight that were less than expected based on data from age- and sex-matched peers.

Venlafaxine and ODV are potent inhibitors of neuronal serotonin and norepinephrine reuptake and weak inhibitors of dopamine reuptake.

Such complications can arise immediately upon delivery. Reported clinical findings have included respiratory distress, cyanosis, apnea, seizures, temperature instability, feeding difficulty, vomiting, hypoglycemia, hypotonia, hypertonia, hyperreflexia, tremor, jitteriness, irritability, and constant crying.

In general, the adverse reaction profile of venlafaxine in placebo-controlled clinical studies in children and adolescents ages 6 to 17 was similar to that seen for adults. Store at room temperature away from moisture and heat. In pediatric clinical studies, the adverse reaction, suicidal ideation, was observed. Suicide is a known risk of depression and certain other psychiatric disorders, and these disorders themselves are the strongest predictors of suicide. There has been a long-standing concern, however, that antidepressants may have a role in inducing worsening of depression and the emergence of suicidality in certain patients during the early phases of treatment. Pooled analyses of short-term placebo-controlled studies of antidepressant drugs SSRIs and others showed that these drugs increase the risk of suicidal thinking and behavior suicidality in children, adolescents, and young adults ages 18 to 24 with MDD and other psychiatric disorders. Short-term studies did not show an increase in the risk of suicidality with antidepressants compared to placebo in adults beyond age 24; there was a reduction with antidepressants compared to placebo in adults aged 65 and older.

In patients receiving antidepressants with pharmacological properties similar to venlafaxine in combination with an MAOI, there have also been reports of serious, sometimes fatal, reactions. For a selective serotonin reuptake inhibitor, these reactions have included hyperthermia, rigidity, myoclonus, autonomic instability with possible rapid fluctuations of vital signs, and mental status changes that include extreme agitation progressing to delirium and coma.

Venlafaxine and ODV exhibited linear kinetics over the dose range of 75 to 450 mg total dose per day administered on a q8h schedule. Plasma clearance, elimination half-life and steady-state volume of distribution were unaltered for both venlafaxine and ODV after multiple-dosing. Eli Lilly and Company, Cornell University, and the Michael J. Fox Foundation.

XR were also administered to 1381 patients in Phase 3 GAD studies, 819 patients in Phase 3 Social Anxiety Disorder studies, and 1314 patients in Phase 3 panic disorder studies. In addition, in premarketing assessment of Effexor, multiple doses were administered to 2897 patients in Phase 2 to Phase 3 studies for major depressive disorder. The conditions and duration of exposure to venlafaxine in both development programs varied greatly, and included in overlapping categories open and double-blind studies, uncontrolled and controlled studies, inpatient Effexor only and outpatient studies, fixed-dose, and titration studies. Untoward events associated with this exposure were recorded by clinical investigators using terminology of their own choosing. Consequently, it is not possible to provide a meaningful estimate of the proportion of individuals experiencing adverse events without first grouping similar types of untoward events into a smaller number of standardized event categories. And it voted 24-13 to limit the maximum acetaminophen dosage in over-the-counter products -- an action Kweder says the FDA isn't yet ready to take.

Antidepressants increased the risk compared to placebo of suicidal thinking and behavior suicidality in children, adolescents, and young adults in short-term studies of Major Depressive Disorder MDD and other psychiatric disorders. Anyone considering the use of Effexor or any other antidepressant in a child, adolescent, or young adult must balance this risk with the clinical need. Short-term studies did not show an increase in the risk of suicidality with antidepressants compared to placebo in adults beyond age 24; there was a reduction in risk with antidepressants compared to placebo in adults aged 65 and older. Depression and certain other psychiatric disorders are themselves associated with increases in the risk of suicide.

Given the decrease in clearance and increase in elimination half-life for both Venlafaxine and ODV that is observed in patients with hepatic cirrhosis and mild and moderate hepatic impairment compared to normal subjects see CLINICAL PHARMACOLOGY it is recommended that the total daily dose be reduced by 50% in patients with mild to moderate hepatic impairment. Since there was much individual variability in clearance between subjects with cirrhosis, it may be necessary to reduce the dose even more than 50%, and individualization of dosing may be desirable in some patients.

Case reports and epidemiological studies case-control and cohort design have demonstrated an association between use of drugs that interfere with serotonin reuptake and the occurrence of gastrointestinal bleeding. Bleeding events related to SSRIs and SNRIs use have ranged from ecchymoses, hematomas, epistaxis, and petechiae to life-threatening hemorrhages.
