5 Warnings and Precautions

5.1 QT Prolongation

Additions and/or revisions underlined:
EGATEN prolongs the QTc interval [see Clinical Pharmacology (12.2)]. The magnitude of QTc prolongation can increase with increasing treatment duration of EGATEN. Administration of EGATEN concurrently with CYP1A2 inhibitors and use in patients with hepatic impairment may result in increased exposures of triclabendazole and/or its metabolites, and, therefore, may increase the risk for QT prolongation.

Monitor electrocardiogram (ECG) in patients with a history of prolongation of the QTc interval or a history of symptoms compatible with a long QT interval or with electrolyte imbalance like hypokalemia, or when EGATEN is used in patients who receive drugs that are known to prolong the QTc interval, or patients taking CYP1A2 inhibitors, or in patients with hepatic impairment. If signs of cardiac arrhythmia occur during treatment with EGATEN, stop the treatment and monitor ECG.

6 Adverse Reactions

6.2 Postmarketing Experience

Additions and/or revisions underlined:

The following adverse reactions have been identified during post-marketing use of EGATEN. 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.

Resistance to triclabendazole has been reported [see Microbiology (12.4)].

PATIENT COUNSELING INFORMATION

QT Prolongation

Additions and/or revisions underlined:

Advise patients with a history of prolongation of the QTc interval or a history of symptoms compatible with a long QT interval or with electrolyte imbalance like hypokalemia or when EGATEN is used in patients who receive drugs that are known to prolong the QTc interval or on CYP1A2 inhibitors or have hepatic impairment that their ECGs will need to be monitored [see Warnings and Precautions (5.1)].
