| Important Safety Information for Savella Savella is a selective serotonin and norepinephrine reuptake inhibitor (SNRI), similar to some drugs used for the treatment of depression and other psychiatric disorders. Antidepressants increased the risk compared to placebo of suicidal thinking and behavior (suicidality) in children, adolescents, and young adults in short-term studies of major depressive disorder (MDD) and other psychiatric disorders. Anyone considering the use of such drugs in a child, adolescent, or young adult must balance this risk with the clinical need. Short-term studies did not show an increase in the risk of suicidality with antidepressants compared to placebo in adults beyond age 24; there was a reduction in risk with antidepressants compared to placebo in adults aged 65 and older. Depression and certain other psychiatric disorders are themselves associated with increases in the risk of suicide. Patients of all ages who are started on Savella should be monitored appropriately and observed closely for clinical worsening, suicidality, or unusual changes in behavior. Families and caregivers should be advised of the need for close observation and communication with the prescriber. Savella is not approved for use in the treatment of major depressive disorder. Savella is not approved for use in pediatric patients. Savella is contraindicated in patients taking monoamine oxidase inhibitors (MAOIs) concomitantly or within 14 days of discontinuing treatment with an MAOI or in patients with uncontrolled narrow-angle glaucoma. Development of a potentially life-threatening serotonin syndrome may occur with agents that inhibit serotonin reuptake, including Savella, particularly with concomitant use of serotonergic drugs (including triptans and tramadol) and with drugs that impair metabolism of serotonin (including MAOIs). The concomitant use of Savella with serotonin precursors is not recommended. Blood pressure and heart rate should be monitored prior to initiating treatment with Savella and periodically throughout treatment. SNRIs, including Savella, have been associated with reports of increases in blood pressure and heart rate. Pre-existing hypertension, tachyarrhythmias and other cardiac diseases should be treated before starting therapy with Savella. Savella should be used with caution in patients with significant hypertension or cardiac disease. For patients who experience a sustained increase in blood pressure or heart rate while receiving Savella, either dose reduction or discontinuation should be considered. Savella should be prescribed with caution in patients with a history of a seizure disorder, mania, or controlled narrow-angle glaucoma. Savella has been associated with mild elevations of ALT and AST. Rarely, fulminant hepatitis has been reported in patients treated with milnacipran. Savella should be discontinued in patients who develop jaundice or other evidence of liver dysfunction and should not be resumed unless another cause can be established. Savella should ordinarily not be prescribed to patients with substantial alcohol use or evidence of chronic liver disease.
As with other SNRIs and SSRIs,
withdrawal symptoms have been observed following discontinuation
of milnacipran. A gradual dose reduction
is recommended.
Hyponatremia may occur as a result of treatment with SSRIs and SNRIs, including Savella. Discontinuation should be considered for patients with symptomatic hyponatremia.
Male patients with a history of obstructive uropathies may experience higher rates of genitourinary adverse events. Savella is unlikely to be involved in clinically significant pharmacokinetic drug interactions. Pharmacodynamic interactions of Savella with other drugs can occur.
The most frequently occurring adverse reactions (≥5% and greater than placebo) were nausea, headache, constipation, dizziness, insomnia, hot flush, hyperhidrosis, vomiting, palpitations, heart rate increased, dry mouth, and hypertension. Prescribing Information |
