effexor liver disease

Tachycardia and QTc prolongation appear to occur in a dose-dependent manner. In one case report, venlafaxine (75 mg 3 times/day) may have contributed to an elevation in defibrillation threshold in a patient with nonischemic cardiomyopathy and an implantable effexor liver disease defibrillator. Symptoms can be minimized by slow tapering or switching to a drug with a longer half-life (e.g., fluoxetine). This increase was duration dependent over the study period and tended to be greater with higher doses. Although effexor liver disease 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. Hyponatremia tends to develop within the first few weeks of treatment (range 3 to 120 days) and typically resolves within 2 weeks (range 48 hours to 6 weeks) after therapy has been discontinued with some patients requiring treatment. Following discontinuation of therapy the amount of REM sleep tends to rebound. Although these events occurred during treatment with venlafaxine, causality has not been determined. Although rare, interstitial pneumonitis secondary to venlafaxine therapy has been reported. The authors state that it is possible that the anasarca was due to an allergic or delayed- type hypersensitivity reaction given the circumstances. There are numerous case reports of withdrawal symptoms following abrupt discontinuation of treatment, and a single case report of severe tinnitus associated with venlafaxine. Withdrawal effects occur upon abrupt discontinuation effexor liver disease treatment and the severity of symptoms appears to be dependent on length of therapy and dose (including low dose therapy).

Nevertheless, the physician who elects to use Effexor/Effexor XR for extended periods should periodically re-evaluate the long-term usefulness of the drug for the individual patient. Events are further categorized by body system and listed in order of decreasing frequency using the following definitions: frequent effexor liver disease events are defined as those occurring on one or more occasions in at least 1/100 patients; infrequent adverse events are those occurring in 1/100 effexor liver disease 1/1000 patients; rare events are those occurring in fewer than 1/1000 patients.
