raw lips from effexor
In premarketing trials, treatment with Effexor tablets was associated with a mean final on-therapy increase in total cholesterol of 3 mg/dL.
Patients treated with Effexor tablets for at least 3 months in placebo-controlled 12-month extension trials had a mean final on-therapy increase in total cholesterol of 9.1 mg/dL compared with a decrease of 7.1 mg/dL among placebo-treated patients. Symptoms resolved following treatment with IV steroids and antidepressant therapy was safely switched to paroxetine. There are not sufficient data with the use of venlafaxine extended-release at doses above 300 raw lips from effexor to determine the incidence of sustained increases in blood pressure at these high doses.
One study has reported average systolic blood pressure increases of 1.7 to 3.4 mm Hg and average diastolic pressure increases of 0.4 to 2.6 mm Hg. There have been reports of increases in prothrombin time, partial thromboplastin time, or INR when venlafaxine was given to patients receiving warfarin therapy.

Side Effects by Body System
Gastrointestinal
Gastrointestinal side effects have frequently included nausea (up to 35%), dry mouth (14% to 18%), constipation (12%), anorexia (12% to 23%), vomiting, diarrhea (5% to 12%), eructation, abdominal pain, and flatulence.
Gastrointestinal side effects reported in premarketing Phase 3 trials have included increased appetite, bruxism, colitis, dysphagia, tongue edema, esophagitis, gastritis, gastroenteritis, gastrointestinal ulcer, gingivitis, glossitis, rectal hemorrhage, hemorrhoids, melena, oral moniliasis, stomatitis, mouth ulceration, abdominal distention, biliary pain, cheilitis, cholecystitis, cholelithiasis, esophageal spasms, duodenitis, hematemesis, gastroesophageal reflux disease, gastrointestinal hemorrhage, gum hemorrhage, hepatitis, ileitis, jaundice, intestinal obstruction, liver tenderness, parotitis, periodontitis, proctitis, rectal disorder, salivary gland enlargement, increased salivation, soft stools, and tongue discoloration.
Nervous system
Nervous system side effects have frequently included dizziness (16%), somnolence (up to 14%), insomnia (11% to 25%), fatigue (11%), nervousness (9%), abnormal dreams, sleep abnormalities, tremor, depression, paresthesia, decreased libido, agitation, hypertonia, anxiety, delirium, and twitching. The reduction in REM sleep is greatest early in treatment, but gradually returns towards baseline during long-term therapy; however, ROL remains long. In addition, in premarketing assessment of Effexor XR (the extended release form of venlafaxine), multiple doses were administered to 705 patients in Phase 3 major depressive disorder studies and Effexor raw lips from effexor administered to raw lips from effexor patients. Although these events occurred during treatment with venlafaxine, causality has not been determined.
Although rare, interstitial pneumonitis secondary to venlafaxine therapy has been reported. 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 mg/dL, 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 raw lips from effexor 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 raw lips from effexor 4 beats per minute for Effexor. Symptoms resolved following discontinuation of therapy.
Genitourinary side effects have frequently included male raw lips from effexor female sexual dysfunction such 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.
Genitourinary side effects reported in premarketing Phase 3 trials have included prostatic disorder (prostatitis, enlarged prostate, and prostate irritability), impaired urination, albuminuria, amenorrhea, cystitis, dysuria, hematuria, leukorrhea, menorrhagia, metrorrhagia, nocturia, breast pain, polyuria, urinary incontinence, urinary retention, urinary urgency, vaginal hemorrhage, vaginitis, abortion, anuria, breast discharge, breast engorgement, balanitis, breast enlargement, endometriosis, female lactation, fibrocystic breast, calcium crystalluria, cervicitis, orchitis, ovarian cyst, bladder pain, prolonged erection, gynecomastia (male), hypomenorrhea, mastitis, menopause, oliguria, salpingitis, urolithiasis, uterine hemorrhage, uterine spasm, and vaginal dryness. Withdrawal symptoms were reported to include brief bursts of dizziness associated with headache, anxiety, irritability, agitation, insomnia, paresthesias, nausea, vomiting, diarrhea, tremor, fatigue, sweating, and worsening of depression (similar to symptoms reported after withdrawal from selective serotonin raw lips from effexor inhibitors). The rule for including events was to enumerate those that occurred at an incidence of 5% or more for at least one of the venlafaxine groups and for which the incidence was at least twice the placebo incidence for raw lips from effexor least one Effexor group. Although these events occurred during treatment with venlafaxine, causality has not been determined.
There is a single case report of breast pain associated with venlafaxine therapy.
Dermatologic
At least 3 cases of venlafaxine- induced alopecia have been reported. The onset of withdrawal symptoms ranges from 14 to 48 hours after the last dose of venlafaxine extended-release and symptoms tend to resolve rapidly (range, within 2 to 24 hours) after resumption of therapy. Experience with the immediate-release venlafaxine showed that sustained hypertension was dose-related, increasing from 3% to 7% at 100 to 300 mg/day to 13% at doses above 300 mg/day. In a flexible-dose study, with raw lips from effexor in the range of 200 to 375 mg/day 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. Tachycardia and QTc prolongation appear to occur in a dose-dependent manner.
In one case report, venlafaxine (75 mg 3 times/day) may raw lips from effexor contributed to an elevation in defibrillation threshold in a patient with nonischemic cardiomyopathy and an implantable cardioverter- defibrillator. The onset of venlafaxine- associated interstitial pneumonitis has ranged from 1 to 18 months after initial exposure to the drug and symptomatic improvement occurred after discontinuation of venlafaxine and treatment with corticosteroids.
