In a Canadian study which found 32 cases in 2002, it was noted that databases like that used in the study tended to include only a small proportion of suspected drug reactions.Protocols are that nefazodone should not be used in patients who have a pre-existing liver condition. Prior to treatment liver enzymes should be tested to make sure there is not an underlying liver condition. If serum AST or serum ALT levels are more than 3 times the upper limit of normal (ULN) should be permanently withdrawn from the drug. Regular enzyme labs should be done every 6 months. Due to liver issues Nefazodone should not be a first line treatment. Common and mild side effects of nefazodone reported in clinical trials more often than placebo include dry mouth (25%), sleepiness (25%), nausea (22%), dizziness (17%), blurred vision (16%), weakness (11%), lightheadedness (10%), confusion (7%), and orthostatic hypotension (5%). Rare and serious adverse reactions may include allergic reactions, fainting, painful/prolonged erection, and jaundice.Nefazodone is not especially associated with increased appetite and weight gain. Interactions
Nefazodone is a potent inhibitor of CYP3A4, and may interact adversely with many commonly used medications that are metabolized by CYP3A4. Pharmacology
Pharmacodynamics
Nefazodone acts primarily as a potent antagonist of the serotonin 5-HT2A receptor and to a lesser extent of the serotonin 5-HT2C receptor. It also has high affinity for the α1-adrenergic receptor and serotonin 5-HT1A receptor, and relatively lower affinity for the α2-adrenergic receptor and dopamine D2 receptor.
Acneiform eruptions are a group of dermatoses including acne vulgaris, rosacea, folliculitis, and perioral dermatitis. Restated, acneiform eruptions are follicular eruptions characterized by papules and pustules resembling acne. The hybrid term acneiform, literally, refers to an appearance similar to acne.The terminology used in this field can be complex, and occasionally contradictory. Some sources consider acne vulgaris part of the differential diagnosis for an acneiform eruption. Other sources classified acne vulgaris under acneiform eruption. MeSH explicitly excludes perioral dermatitis from the category of "acneiform eruptions", though it does group acneiform eruptions and perioral dermatitis together under "facial dermatoses". See also
