5 Warnings and Precautions

5.10 Increased Risk of Bleeding

Subsection title revised

Additions and revisions underlined:

SSRIs and SNRIs, including Fluvoxamine Maleate Tablets, may increase the risk of bleeding events. Concomitant use of aspirin, nonsteroidal anti-inflammatory drugs, warfarin, and other anticoagulants may add to this risk. Case reports and epidemiological studies (case-control and cohort design) have demonstrated an association between use of drugs that interfere with serotonin reuptake and the occurrence of gastrointestinal bleeding. Based on data from the published observational studies, exposure to SSRIs, particularly in the month before delivery, has been associated with a less than 2-fold increase in the risk of postpartum hemorrhage [see Use in Specific Populations (8.1)]. Bleeding events related to SSRIs and SNRIs have ranged from ecchymoses, hematomas, epistaxis, and petechiae to life-threatening hemorrhages.

Patients should be cautioned about the increased risk of bleeding associated with the concomitant use of Fluvoxamine Maleate Tablets and NSAIDs, aspirin, or other drugs that affect coagulation [see Warnings and Precautions (5.8)].

5.2 Serotonin Syndrome

Additions and revisions underlined:

Selective serotonin reuptake inhibitors (SSRIs), including Fluvoxamine Maleate Tablets, can precipitate serotonin syndrome, a potentially life-threatening condition. The risk is increased with concomitant use of other serotonergic drugs (including triptans, tricyclic antidepressants, fentanyl, meperidine, methadone, lithium, tramadol, tryptophan, buspirone, amphetamines, and St. John's Wort) and with drugs that impair metabolism of serotonin, i.e., MAOIs [see Contraindications (4), Drug Interactions (7.1)]. Serotonin syndrome can also occur when these drugs are used alone.

Serotonin syndrome signs and symptoms may include mental status changes (e.g., agitation, hallucinations, delirium, and coma), autonomic instability (e.g., tachycardia, labile blood pressure, dizziness, diaphoresis, flushing, hyperthermia), neuromuscular symptoms (e.g., tremor, rigidity, myoclonus, hyperreflexia, incoordination), seizures, and gastrointestinal symptoms (e.g., nausea, vomiting, diarrhea). Patients should be monitored for the emergence of serotonin syndrome.

The concomitant use of Fluvoxamine Maleate Tablets with MAOIs is contraindicated. In addition, do not initiate Fluvoxamine Maleate Tablets in a patient being treated with MAOIs such as linezolid or intravenous methylene blue. No reports involved the administration of methylene blue by other routes (such as oral tablets or local tissue injection). If it is necessary to initiate treatment with an MAOI such as linezolid or intravenous methylene blue in a patient taking Fluvoxamine Maleate Tablets, discontinue Fluvoxamine Maleate Tablets before initiating treatment with the MAOI [see Contraindications (4), Drug Interactions (7.2)].

Monitor all patients taking Fluvoxamine Maleate Tablets for the emergence of serotonin syndrome. Discontinue treatment with Fluvoxamine Maleate Tablets and any concomitant serotonergic agents immediately if the above symptoms occur, and initiate supportive symptomatic treatment. If concomitant use of Fluvoxamine Maleate Tablets with other serotonergic drugs is clinically warranted, inform patients of the increased risk for serotonin syndrome and monitor for symptoms.

6 Adverse Reactions

6.9 Postmarketing Reports

Additions and revisions underlined:

The following adverse reactions have been identified during post-approval use of Fluvoxamine Maleate Tablets. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure.

Voluntary reports of adverse reactions in patients taking Fluvoxamine Maleate Tablets that have been received since market introduction and are of unknown causal relationship to Fluvoxamine Maleate Tablets use include: acute renal failure, agranulocytosis, amenorrhea, anaphylactic reaction, angioedema, anosmia, aplastic anemia, bullous eruption, Henoch-Schoenlein purpura, hepatitis, hyposmia, ileus, pancreatitis, porphyria, Stevens-Johnson syndrome, toxic epidermal necrolysis, vasculitis, and ventricular tachycardia (including torsades de pointes).

7 Drug Interactions

7.2 CNS Active Drugs

Newly added information:

Other Serotonergic Drugs: The concomitant use of serotonergic drugs (including other SSRIs, SNRIs, triptans, tricyclic antidepressants, opioids, lithium, buspirone, amphetamines, tryptophan, and St. John's Wort) with Fluvoxamine Maleate Tablets increases the risk of serotonin syndrome. Monitor patients for signs and symptoms of serotonin syndrome, particularly during treatment initiation and dosage increases. If serotonin syndrome occurs, consider discontinuation of Fluvoxamine Maleate Tablets and/or concomitant serotonergic drugs [see Warnings and Precautions (5.2)].

8 Use in Specific Populations

8.1 Pregnancy

Newly added information:

Based on data from published observational studies, exposure to SSRIs, particularly in the month before delivery, has been associated with a less than 2-fold increase in the risk of postpartum hemorrhage [see Warnings and Precautions (5.10) and Clinical Considerations].

5 Warnings and Precautions

5.16 Sexual Dysfunction

(Newly added subsection)

Use of SSRIs, including Fluvoxamine Maleate Tablets, may cause symptoms of sexual dysfunction [see Adverse Reactions (6.4)]. In male patients, SSRI use may result in ejaculatory delay or failure, decreased libido, and erectile dysfunction. In female patients, SSRI use may result in decreased libido and delayed or absent orgasm.

It is important for prescribers to inquire about sexual function prior to initiation of Fluvoxamine Maleate Tablets and to inquire specifically about changes in sexual function during treatment, because sexual function may not be spontaneously reported. When evaluating changes in sexual function, obtaining a detailed history (including timing of symptom onset) is important because sexual symptoms may have other causes, including the underlying psychiatric disorder. Discuss potential management strategies to support patients in making informed decisions about treatment.

8 Use in Specific Populations

8.1     Pregnancy

(Pregnancy and Lactation Labeling Rule (PLLR) conversion; please refer to label)

8.2     Lactation

(Pregnancy and Lactation Labeling Rule (PLLR) conversion; additions and/or revisions underlined)

Data from published literature report the presence of fluvoxamine is in human milk. No adverse effects on the breastfed infant have been reported in most cases of maternal use of fluvoxamine during breastfeeding. However, there are reports of diarrhea, vomiting, decreased sleep, and agitation. There are no data on the effect of fluvoxamine on milk production. The developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for fluvoxamine and any potential adverse effects on the breastfed child from fluvoxamine or from the underlying maternal condition.

Clinical Considerations

Monitor infants exposed to fluvoxamine through breast milk for diarrhea, vomiting, decreased sleep, and agitation.

Data

Milk drug concentrations less than or equal to 425 ng/mL were observed following maternal dosing of fluvoxamine 25 mg/day to 300 mg/day in published case reports and case series.

8.3     Females and Males of Reproductive Potential

(Newly added subsection)

Infertility

Animal findings suggest fertility may be impaired while taking fluvoxamine.
