ECG Changes
In an analysis of ECGs obtained in 769 patients treated with Effexor and 450 patients treated with effexor xr refills in controlled clinical trials, the only statistically significant difference observed was for heart rate, ie, a mean increase from baseline of 4 beats per minute for Effexor. Although these events occurred during treatment with venlafaxine, causality has not been determined. Although these events occurred during treatment with venlafaxine, causality has not been determined.
Although rare, interstitial pneumonitis secondary to venlafaxine therapy has been reported. Although these events occurred during treatment with venlafaxine, causality has not been determined.
There have been a minimum of approximately fifteen cases of hyponatremia in which at least one was life effexor xr refills including at least one case of recurrent venlafaxine- induced hyponatremia after rechallenge.
A recent short-term study (6 weeks) has reported an average weight loss of 2 to 3 pounds in patients treated with venlafaxine.
Numerous cases of hyponatremia have been reported following treatment with a selective serotonin reuptake inhibitor (SSRI). Although these events occurred during treatment with venlafaxine, causality has not been determined.
Respiratory
Respiratory side effects have frequently included pharyngitis, sinusitis, and yawning.
Respiratory side effects reported in premarketing Phase 3 trials have included increased cough, dyspnea, asthma, chest congestion, epistaxis, hyperventilation, laryngismus, laryngitis, pneumonia, voice alteration, atelectasis, hemoptysis, hypoventilation, hypoxia, larynx edema, pleurisy, pulmonary embolus, and sleep apnea. Tests for potential dose relationships for these events (Cochran-Armitage Test, with a criterion of exact 2-sided p-value ≤ 0.05) suggested a dose-dependency for several adverse events in this list, including chills, hypertension, anorexia, nausea, agitation, dizziness, somnolence, tremor, yawning, sweating, and abnormal ejaculation.

Adaptation to Certain Adverse Events
Over a 6-week period, there was evidence of effexor xr refills to some adverse events with continued therapy (eg, dizziness and nausea), but less to other effects (eg, abnormal ejaculation and dry effexor xr refills Sign Changes
Effexor (venlafaxine hydrochloride) treatment (averaged over all dose groups) in clinical trials was associated with a mean increase in pulse rate of approximately 3 beats per minute, compared to no change for placebo. Although these events occurred during treatment with venlafaxine, causality has not been effexor xr refills coordination and balance have been reported in postmarketing studies.
Seizures have been reported in 0.26% of treated patients during premarketing testing. In a flexible-dose study, with doses in the range of 200 to 375 mg/day and mean dose greater than 300 mg/day, the mean pulse was increased by about 2 beats per minute compared with a decrease of about 1 beat per minute for placebo.
In controlled clinical trials, Effexor was associated with mean increases in diastolic blood pressure ranging from 0.7 to 2.5 mm Hg averaged over all dose groups, compared to mean decreases ranging from 0.9 to 3.8 mm Hg for placebo. 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.
In the tabulations that follow, reported adverse events were classified using a standard COSTART-based Dictionary terminology. Some of these drugs (i.e., bupropion, mirtazapine, nefazodone, trazodone, trimipramine) appear to have a modest or minimal effect on REM sleep.

In the tabulations that follow, reported adverse events were classified using a standard COSTART-based Dictionary terminology. Untoward events associated with this exposure were recorded by clinical investigators using terminology of their own choosing.
