menopause effexor
In the event that therapy is not reintroduced, withdrawal symptoms may last from 5 to 7 days before resolving spontaneously.
In one case report, withdrawal- induced full mania developed menopause effexor a 33- year- old patient following abrupt termination of treatment with venlafaxine extended-release (150 mg daily for 10 weeks).
Hepatic
Hepatic side effects menopause effexor included toxic hepatitis. Additional data are required to confirm this finding.
Cardiovascular side effects have frequently included vasodilatation, hypertension, palpitation, postural menopause effexor and tachycardia.
Cardiovascular side effects reported in premarketing Phase 3 menopause effexor have menopause effexor angina pectoris, arrhythmia, bradycardia, extrasystoles, hypotension, peripheral vascular disorder (mainly cold feet and/or cold hands), syncope, thrombophlebitis, aortic aneurysm, arteritis, first-degree atrioventricular block, bigeminy, bundle branch block, capillary fragility, cerebral ischemia, coronary artery disease, congestive heart failure, heart arrest, hematoma, cardiovascular disorder (mitral valve menopause effexor circulatory disturbance), mucocutaneous hemorrhage, myocardial infarct, pallor, and sinus arrhythmia. The conditions and duration of exposure to venlafaxine in both development menopause effexor 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 menopause effexor Clinically relevant increases in serum cholesterol, defined as 1) a final on-therapy increase in serum cholesterol ≥50 mg/dL from baseline and to a value ≥261 mg/dL or 2) an average on‑therapy increase in serum cholesterol ≥50 mg/dL from baseline and to a value ≥261 menopause effexor were recorded in 5.3% of venlafaxine-treated patients and 0.0% of placebo-treated patients.
ECG Changes
In an analysis of ECGs obtained in 769 patients treated with Effexor and 450 patients treated with placebo 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. In the event that therapy is not reintroduced, withdrawal symptoms may last from 5 to 7 days before resolving spontaneously.
In one case report, withdrawal- induced full mania developed in a 33- year- old patient following abrupt termination of treatment with venlafaxine extended-release (150 mg menopause effexor for 10 weeks).
Hepatic
Hepatic side effects have included toxic hepatitis. The reduction in REM sleep is greatest early in treatment, but gradually returns towards baseline during long-term therapy; however, ROL remains long. Dyskinesia has also been reported.
Venlafaxine has been reported to increase the pain tolerance threshold to electrical sural nerve stimulation and the threshold at which pain increases (pain summation).
One case of serotonin syndrome has been reported which is believed to have been precipitated by the combination of venlafaxine and trazodone.
One small study has suggested menopause effexor venlafaxine may improve attention, concentration, memory, and reaction time performance after single oral doses.
Nervous system side effects reported in premarketing Phase 3 trials have included amnesia, confusion, depersonalization, hypesthesia, abnormal thinking, trismus, vertigo, akathisia, apathy, ataxia, circumoral paresthesia, central nervous system (CNS) stimulation, hostility, hyperesthesia, hyperkinesia, hypotonia, incoordination, myoclonus, neuralgia, neuropathy, menopause effexor abnormal speech, stupor, adjustment disorder, akinesia, alcohol abuse, aphasia, bradykinesia, buccoglossal syndrome, cerebrovascular accident, feeling drunk, loss of consciousness, dementia, dystonia, increased energy, facial paralysis, abnormal gait, Guillain-Barre Syndrome, hyperchlorhydria, hypokinesia, hysteria, impulse control difficulties, increased libido, motion sickness, neuritis, nystagmus, paresis, decreased or increased reflexes, and torticollis. Although these events occurred during treatment with venlafaxine, causality has not been determined.
Although rare, interstitial pneumonitis secondary to venlafaxine therapy has been reported. This increase was duration dependent over the study period and tended to be greater with higher doses. Symptoms resolved following discontinuation of therapy.
Genitourinary side effects have frequently included male and female sexual dysfunction menopause effexor as abnormal ejaculation in up to 16% of male patients, decreased libido (13%), impotence (13%), and organic dysfunction (anorgasmia or abnormal orgasm) in up to 8% of female patients.

In a flexible-dose study, with doses in the range of 200 to 375 menopause effexor and mean dose greater than 300 mg/day, the mean change in heart rate was 8.5 beats per minute compared with 1.7 beats per minute for placebo.
Other Events Observed During the Premarketing Evaluation of Venlafaxine
During its premarketing assessment, multiple doses of Effexor were administered to 2897 patients in Phase 2 and Phase 3 studies. The frequencies presented, therefore, represent the proportion of the 5356 patients exposed to multiple doses of either formulation of venlafaxine who experienced an event of the type cited on at least one occasion while receiving venlafaxine. Tests for potential dose relationships for these events (Cochran-Armitage Test, with a menopause effexor 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 adaptation to some adverse events with continued therapy (eg, dizziness and nausea), but less to other effects (eg, abnormal ejaculation and dry mouth).
Vital 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 menopause effexor per minute, compared to no change for placebo. The reduction in REM sleep is greatest early in treatment, but gradually returns towards baseline during long-term therapy; however, ROL remains long. Although these events occurred during treatment with venlafaxine, causality has not been determined.
Musculoskeletal
Musculoskeletal side effects have included rhabdomyolysis.
Musculoskeletal side effects reported in premarketing Phase 3 menopause effexor have included arthralgia, arthritis, arthrosis, bone spurs, bursitis, leg cramps, myasthenia, tenosynovitis, bone pain, pathological fracture, muscle cramp, muscle spasms, musculoskeletal stiffness, myopathy, osteoporosis, osteosclerosis, plantar fasciitis, rheumatoid arthritis, and tendon rupture. The onset of venlafaxine- associated interstitial menopause effexor has ranged from 1 to 18 months after initial exposure to the drug and symptomatic improvement occurred after discontinuation of venlafaxine and treatment menopause effexor corticosteroids.

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. Dermatologic side effects reported in premarketing Phase 3 trials have included pruritus, acne, alopecia, contact dermatitis, dry skin, eczema, maculopapular rash, psoriasis, menopause effexor brittle nails, erythema nodosum, exfoliative dermatitis, lichenoid dermatitis, hair discoloration, skin menopause effexor furunculosis, hirsutism, leukoderma, miliaria, petechial rash, pruritic rash, pustular rash, vesiculobullous rash, seborrhea, skin atrophy, skin hypertrophy, skin striae, and decreased sweating.
