Luvox CR (fluvoxamine maleate) is a selective serotonin reuptake inhibitor (SSRI) antidepressant used to treat social anxiety disorder (social phobia), or obsessive-compulsive disorders involving recurring thoughts or actions. Common side effects of Luvox CR include nausea, vomiting, loss of appetite, upset stomach, drowsiness, dizziness, diarrhea, gas, trouble sleeping (insomnia), increased sweating, skin rash, weakness, yawning, anxiety, dry mouth, sore throat, heavy menstrual periods, muscle pain, decreased sex drive, abnormal ejaculation, or trouble having an orgasm. Tell your doctor if your depression worsens or if you have suicidal thoughts while taking Luvox CR.
The recommended starting dose of Luvox CR is 100 mg at bedtime, with weekly increases of 50 mg as tolerated to maximum therapeutic benefit, not to exceed 300 mg per day. Luvox CR may interact with medicines for pain, arthritis, fever, or swelling, aspirin and NSAIDs (nonsteroidal anti-inflammatory drugs), carbamazepine, clopidogrel, clozapine, diuretics (water pills), linezolid, lithium, methadone, mexiletine, omeprazole, phenytoin, propranolol, quinidine, ramelteon, St. John's wort, tacrine, tramadol, tryptophan, theophylline, blood thinners, sedatives, almotriptan, frovatriptan, sumatriptan, naratriptan, rizatriptan, zolmitriptan, triptans, medicine to treat psychiatric disorders, or other antidepressants. Tell your doctor all medications and supplements you use. Use Luvox CR only when prescribed during pregnancy. It may harm a fetus. Babies born to mothers who have used this drug during the last 3 months of pregnancy may infrequently develop withdrawal symptoms such as feeding/breathing difficulties, seizures, muscle stiffness, or constant crying. If you notice symptoms in your newborn, tell the doctor. Since untreated depression can be a serious condition, do not stop taking this medication unless directed by your doctor. This drug passes into breast milk and could have undesirable effects on a nursing infant. Breastfeeding is not recommended while using this drug.

Luvox CR FDA Prescribing Information: Side Effects
Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in clinical practice.
Clinical Trial Data Sources
LUVOX CR Capsules were studied in one 12-week controlled trial in patients with OCD (N = 124; mean exposure 66.6 days) and in two 12-week controlled trials for another condition (N = 279; mean exposure 59.2 days). Patients in these trials were initiated on 100 mg/day and were titrated in 50 mg increments over the first 6 weeks to within a range of 100 mg to 300 mg/day. The reactions listed in Table 2 show reactions from the two populations separately. Table 3 shows reactions from the three controlled studies combined.
Adverse Reactions Observed In Controlled Trials
Adverse Reactions Associated with Discontinuation of Treatment
Of the 124 patients with OCD and 279 patients in other studies treated with LUVOX CR Capsules in controlled clinical trials, 19% and 26% discontinued treatment due to an adverse reaction. The most common reactions ( ≥ 1%) associated with discontinuation and considered to be drug related (i.e., those reactions associated with dropout at a rate at least twice that of placebo) were anorexia (including, but not limited to, loss of appetite and decreased appetite) (1%), anxiety (3%), asthenia (3%), diarrhea (2%), dizziness (4%), headache (2%), insomnia (5%), nausea (7%), nervousness (1%), somnolence (5%), and thinking abnormal (1%).
Commonly Observed Adverse Reactions
LUVOX CR Capsules have been studied in one controlled trial in patients with OCD (N = 124) and two controlled trials for another condition (N = 279). In general, adverse reaction rates were similar in the two data sets as well as in a study of pediatric patients with OCD treated with immediate-release fluvoxamine maleate tablets. The most commonly observed treatment-emergent adverse reactions associated with the use of LUVOX CR Capsules and likely to be drug-related (incidence of 5% or greater and at least twice that for placebo) and derived from Table 2 were: abnormal ejaculation, anorexia, anorgasmia, asthenia, diarrhea, nausea, somnolence, sweating, and tremor. In the one controlled trial in patients with OCD, the following additional reactions occurred at an incidence of 5% or greater and at least twice that for placebo: anxiety, decreased libido, myalgia, pharyngitis, and vomiting. The following additional reactions occurred in another studied population: dyspepsia, dizziness, insomnia, and yawning. In a study evaluating immediate-release fluvoxamine maleate tablets in pediatric patients with OCD, the following additional reactions were identified using the above rule: agitation, depression, dysmenorrhea, flatulence, hyperkinesia, and rash.
Adverse Reactions Occurring at an Incidence of ≥ 2%
Table 2 enumerates adverse reactions that occurred in adults at a frequency of 2% or more, and were more frequent than in the placebo group, among patients treated with LUVOX CR Capsules in two short-term, placebo-controlled trials (12 weeks) in another population and one short-term placebo-controlled OCD trial (12 weeks) and in which patients were dosed once-a-day in a range of 100 to 300 mg/day. This table shows the percentage of patients in each group who had at least one occurrence of a reaction at some time during their treatment. Reported adverse reactions were classified using a COSTART-based Dictionary terminology.
The prescriber should be aware that these figures cannot be used to predict the incidence of side effects in the course of usual medical practice where patient characteristics and other factors may differ from those that prevailed in the clinical trials. Similarly, the cited frequencies cannot be compared with figures obtained from other clinical investigations involving different treatments, uses, and investigators. The cited figures, however, do provide the prescribing health care provider with some basis for estimating the relative contribution of drug and non-drug factors to the side-effect incidence rate in the population studied.

|1Events for which fluvoxamine maleate
incidence was equal to or less than placebo include the following for OCD
patients: abdominal pain, flu syndrome, infection, palpitation, flatulence,
increased appetite, weight gain, abnormal dreams, amnesia, hypertonia,
nervousness, paresthesia, increased cough, dyspnea, rhinitis, and ear pain. In
the other studied population the following events were seen: abdominal pain,
accidental injury, back pain, flu syndrome, infection, pain, flatulence,
pharyngitis, rhinitis, rash, and dysmenorrhea.
2Term includes body aches/pains, dental pain, pain from surgery, unspecified pain, and general pain secondary to injuries (sprains, fractures).
3Includes, but is not limited to, loss of appetite and decreased appetite.
Other Adverse Reactions In OCD Pediatric Population
In pediatric patients (N=57) treated with immediate-release fluvoxamine maleate tablets, the overall profile of adverse reactions was generally similar to that seen in adult studies, as shown in Table 2. However, the following adverse reactions, not appearing in Table 2, were reported in two or more of the pediatric patients and were more frequent with immediate-release fluvoxamine maleate tablets than with placebo: cough increase, dysmenorrhea, ecchymosis, emotional lability, epistaxis, hyperkinesia, manic reaction, rash, sinusitis, and weight decrease.
Male And Female Sexual Dysfunction With SSRIs
Although changes in sexual desire, sexual performance, and sexual satisfaction often occur as manifestations of a psychiatric disorder and with aging, they may also be a consequence of pharmacologic treatment. In particular, some evidence suggests that selective serotonin reuptake inhibitors (SSRIs) can cause such untoward sexual experiences.
Reliable estimates of the incidence and severity of untoward experiences involving sexual desire, performance, and satisfaction are difficult to obtain, however, in part because patients and health care providers may be reluctant to discuss them. Accordingly, estimates of the incidence of untoward sexual experience and performance cited in product labeling are likely to underestimate their actual incidence.
Table 3 displays the incidence of sexual side effects reported by at least 2% of patients taking LUVOX CR Capsules in placebo-controlled trials.
TABLE 3 : PERCENTAGE OF PATIENTS REPORTING SEXUAL
ADVERSE REACTIONS IN PLACEBO-CONTROLLED TRIALS
N = 403
N = 400
|Sexual Function Abnormal|
While it is difficult to know the precise risk of sexual dysfunction associated with the use of SSRIs, health care providers should routinely inquire about such possible side effects.
Weight And Vital Sign Changes
No statistically significant differences in weight gain or loss were found between patients treated with LUVOX CR Capsules or placebo. Comparisons of immediate-release fluvoxamine maleate tablets or LUVOX CR Capsules versus placebo groups in separate short-term trials on (1) median change from baseline on various vital signs variables and on (2) incidence of patients meeting criteria for potentially important changes from baseline on various measures of vital signs variables revealed no important differences between fluvoxamine maleate and placebo.
Comparisons of immediate-release fluvoxamine maleate tablets or LUVOX CR Capsules versus placebo groups in separate short-term trials on (1) median change from baseline on various serum chemistry, hematology, and urinalysis variables and on (2) incidence of patients meeting criteria for potentially important changes from baseline on various serum chemistry, hematology, and urinalysis variables revealed no important differences between fluvoxamine maleate and placebo.
Comparisons of immediate-release fluvoxamine maleate tablets or LUVOX CR Capsules and placebo groups in separate pools of short-term OCD and depression trials on (1) mean change from baseline on various ECG variables and on (2) incidence of patients meeting criteria for potentially important changes from baseline on various ECG variables revealed no important differences between fluvoxamine maleate and placebo.
Other Reactions Observed During The Premarketing Evaluation Of Fluvoxamine
During premarketing clinical trials conducted in North America and Europe, multiple doses of LUVOX CR Capsules or immediate-release fluvoxamine maleate tablets were administered for a combined total of 3219 patient exposures in patients suffering OCD or other studied disorders. These exposures include 482 patient exposures with LUVOX CR Capsules and 2737 patient exposures with immediate-release fluvoxamine maleate tablets. Untoward reactions associated with this exposure were recorded by clinical investigators using descriptive terminology of their own choosing. Consequently, it is not possible to provide a meaningful estimate of the proportion of individuals experiencing adverse reactions without first grouping similar types of untoward reactions into a limited (i.e., reduced) number of standard reaction categories.
In the tabulations that follow, a COSTART-based Dictionary terminology has been used to classify reported adverse reactions. If the COSTART term for a reaction was so general as to be uninformative, it was replaced with a more informative term when possible. The frequencies presented, therefore, represent the proportion of the total patient exposures to multiple doses of fluvoxamine maleate who experienced a reaction of the type cited on at least one occasion while receiving fluvoxamine maleate. Reactions are further classified within body system categories and enumerated in order of decreasing frequency using the following definitions: frequent adverse reactions are defined as those occurring on one or more occasions in at least 1/100 patients; infrequent adverse reactions are those occurring between 1/100 and 1/1000 patients; and Rare adverse reactions are those occurring in less than 1/1000 patients. It is important to emphasize that, although the events reported did occur during treatment with fluvoxamine maleate, a causal relationship to fluvoxamine maleate has not been established.
For LUVOX CR, all reported events are included in the list below, with the following exclusions: 1) those events already listed in Table 2 or previous sections of this prescribing information; 2) those events for which there is no basis to suspect a causal relationship; and 3) events that were reported in only one patient and judged not to be potentially serious.
