Sertraline (Page 4 of 9)

6.2 Postmarketing Experience

The following adverse reactions have been identified during postapproval use of sertraline hydrochloride 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.

Bleeding or Clotting Disorders

Increased coagulation times (altered platelet function)

Cardiac Disorders

AV block, bradycardia, atrial arrhythmias, QT-interval prolongation, ventricular tachycardia (including Torsade de Pointes)

Endocrine Disorders

Gynecomastia, hyperprolactinemia, menstrual irregularities, SIADH

Eye Disorders

Blindness, optic neuritis, cataract

Hepatobiliary Disorders

Severe liver events (including hepatitis, jaundice, liver failure with some fatal outcomes), pancreatitis

Hemic and Lymphatic

Agranulocytosis, aplastic anemia and pancytopenia, leukopenia, thrombocytopenia, lupus-like syndrome, serum sickness

Immune System Disorders

Angioedema

Metabolism and Nutrition Disorders

Hyponatremia, hyperglycemia

Musculoskeletal and Connective Tissue Disorders

Trismus

Nervous System Disorders

Serotonin syndrome, extrapyramidal symptoms (including akathisia and dystonia), oculogyric crisis

Psychiatric Disorders

Psychosis, enuresis, paroniria

Renal and Urinary Disorders

Acute renal failure

Respiratory, Thoracic and Mediastinal Disorders

Pulmonary hypertension

Skin and Subcutaneous Tissue Disorders

Photosensitivity skin reaction and other severe cutaneous reactions, which potentially can be fatal, such as Stevens-Johnson Syndrome (SJS) and toxic epidermal necrolysis (TEN)

Vascular Disorders

Cerebrovascular spasm (including reversible cerebral vasoconstriction syndrome and Call- Fleming syndrome), vasculitis

7 DRUG INTERACTIONS

7.1 Clinically Significant Drug Interactions

Table 5 includes clinically significant drug interactions with sertraline hydrochloride [See Clinical Pharmacology ( 12.3)].

Table 5. Clinically-Significant Drug Interactions with Sertraline Hydrochloride
Monoamine Oxidase Inhibitors ( MAOIs )
Clinical Impact : The concomitant use of SSRIs including sertraline hydrochloride and MAOIs increases the risk of serotonin syndrome.
Intervention : Sertraline hydrochloride is contraindicated in patients taking MAOIs, including MAOIs such as linezolid or intravenous methylene blue [ See Dosage and Administration ( 2 . 5 ), Contraindications ( 4 ), Warnings and Precautions ( 5 . 2)].
Examples : selegiline, tranylcypromine, isocarboxazid, phenelzine, linezolid, methylene blue
Pimozide
Clinical Impact : Increased plasma concentrations of pimozide, a drug with a narrow therapeutic index, may increase the risk of QT prolongation and ventricular arrhythmias.
Intervention : Concomitant use of pimozide and sertraline hydrochloride is contraindicated [ See Contraindications ( 4)].
Other Serotonergic Drugs
Clinical Impact : The concomitant use of serotonergic drugs with sertraline hydrochloride increases the risk of serotonin syndrome.
Intervention : Monitor patients for signs and symptoms of serotonin syndrome, particularly during treatment initiation and dosage increases. If serotonin syndrome occurs, consider discontinuation of sertraline hydrochloride and/or concomitant serotonergic drugs [ See Warnings and Precautions ( 5 . 2)].
Examples : other SSRIs, SNRIs, triptans, tricyclic antidepressants, fentanyl, lithium, tramadol, tryptophan, buspirone, St. John’s Wort
Drugs that Interfere with Hemostasis ( antiplatelet agents and anticoagulants )
Clinical Impact : The concurrent use of an antiplatelet agent or anticoagulant with sertraline hydrochloride may potentiate the risk of bleeding.
Intervention : Inform patients of the increased risk of bleeding associated with the concomitant use of sertraline hydrochloride and antiplatelet agents and anticoagulants. For patients taking warfarin, carefully monitor the international normalized ratio [ See Warnings and Precautions ( 5 . 3)].
Examples : aspirin, clopidogrel, heparin, warfarin
Drugs Highly Bound to Plasma Protein
Clinical Impact : Sertraline hydrochloride is highly bound to plasma protein. The concomitant use of sertraline hydrochloride with another drug that is highly bound to plasma protein may increase free concentrations of sertraline hydrochloride or other tightly-bound drugs in plasma [ See Clinical Pharmacology ( 12 . 3 )].
Intervention : Monitor for adverse reactions and reduce dosage of sertraline hydrochloride or other protein-bound drugs as warranted.
Examples : warfarin
Drugs Metabolized by CYP2D6
Clinical Impact : Sertraline hydrochloride is a CYP2D6 inhibitor [ See Clinical Pharmacology ( 12 . 3)]. The concomitant use of sertraline hydrochloride with a CYP2D6 substrate may increase the exposure of the CYP2D6 substrate.
Intervention : Decrease the dosage of a CYP2D6 substrate if needed with concomitant sertraline hydrochloride use. Conversely, an increase in dosage of a CYP2D6 substrate may be needed if sertraline hydrochloride is discontinued.
Examples : propafenone, flecainide, atomoxetine, desipramine, dextromethorphan, metoprolol, nebivolol, perphenazine, thoridazine, tolterodine, venlafaxine
Phenytoin
Clinical Impact : Phenytoin is a narrow therapeutic index drug. Sertraline hydrochloride may increase phenytoin concentrations.
Intervention : Monitor phenytoin levels when initiating or titrating sertraline hydrochloride. Reduce phenytoin dosage if needed.
Examples : phenytoin, fosphenytoin
