TIGLUTIK For PEG Tube Administration

TIGLUTIK is the only formulation of riluzole approved for use with a PEG tube. Both silicone and polyurethane PEG tubes can be used.1  TIGLUTIK conveniently allows patients to get their prescribed dose of riluzole, and it eliminates the risk of crushed tablets clogging their feeding tube. TIGLUTIK is administered by placing the tip of the oral syringe containing TIGLUTIK 10 mL into the PEG tube.  The plunger is slowly pushed until the oral syringe is empty.

PEG Tube Administration

A national survey of 887 people with ALS shows that 26% of patients have a PEG tube.2 Before the approval of TIGLUTIK, patients treated with riluzole had no other option but to crush their riluzole tablets. Crushed tablets are the most common cause of PEG tube occlusion occurring in up to 35% of patients.3 Clogged PEG tubes can lead to dehydration, malnutrition, and additional surgery.4  TIGLUTIK aligns with recommendations that patients with enteral feeding tubes should use liquid formulations of medication whenever possible.3

Important Safety Information


TIGLUTIK is contraindicated in patients with a history of severe hypersensitivity reactions to riluzole or to any of its components.

Warnings and Precautions

TIGLUTIK can cause liver injury and there have been cases of drug-induced liver injury, some of which were fatal, in patients taking riluzole. Asymptomatic elevations of hepatic transaminases have been reported and, in some patients, have recurred upon re-challenge with riluzole. Maximum increases in ALT occurred within 3 months after starting riluzole. Monitor patients for hepatic injury every month for the first 3 months of treatment, and periodically thereafter; TIGLUTIK should be discontinued if there is evidence of liver dysfunction, for example, elevated bilirubin. Use of TIGLUTIK with other hepatotoxic drugs may increase the risk for hepatotoxicity.

TIGLUTIK can cause neutropenia. Cases of severe neutropenia (absolute neutrophil count less than 500 per mm3) within the first 2 months of riluzole treatment have been reported. Advise patients to report febrile illnesses.

TIGLUTIK can cause interstitial lung disease, including hypersensitivity pneumonitis. Discontinue TIGLUTIK immediately if interstitial lung disease develops.

Adverse Reactions

The most common adverse reactions (incidence greater than or equal to 5% and greater than placebo) of TIGLUTIK were oral hypoesthesia (29%), asthenia (19%), nausea (16%), decreased lung function (10%), hypertension (5%), and abdominal pain (5%).

Coadministration of TIGLUTIK with strong or moderate CYP1A2 inhibitors, such as ciprofloxacin, enoxacin, fluvoxamine, methoxsalen, mexiletine, oral contraceptives, thiabendazole, vemurafenib, and zileuton, may increase the risk of TIGLUTIK-associated adverse reactions. 

Coadministration of TIGLUTIK with CYP1A2 inducers may result in decreased efficacy of TIGLUTIK.

Use in Specific Populations

Patients with mild or moderate hepatic impairment (Child-Pugh’s score A or B) had increases in AUC compared to patients with normal hepatic function. Thus, patients with mild or moderate hepatic impairment may be at increased risk of adverse reactions. Use of TIGLUTIK is not recommended in patients with baseline elevations of serum aminotransferases greater than 5 times the upper limit of normal or evidence of liver dysfunction.

Japanese patients are more likely to have higher riluzole concentrations, and thus may be at a greater risk of adverse reactions.
