RELGAABI

GABAPENTIN

Standard Dose
2 DOSAGE AND ADMINISTRATION Postherpetic Neuralgia ( 2.1 ) o Dose can be titrated up as needed to a dose of 1800 mg/day o Day 1: Single 300 mg dose o Day 2: 600 mg/day (i.e., 300 mg two times a day) o Day 3: 900 mg/day (i.e., 300 mg three times a day) Epilepsy with Partial Onset Seizures ( 2.2 ) Patients 12 years of age and older: starting dose is 300 mg three times daily; may be titrated up to 600 mg three times daily Patients 3 to 11 years of age: starting dose range is 10 to 15 mg/kg/day, given in three divided doses; recommended dose in patients 3 to 4 years of age is 40 mg/kg/day, given in three divided doses; the recommended dose in patients 5 to 11 years of age is 25 to 35 mg/kg/day, given in three divided doses. The recommended dose is reached by upward titration over a period of approximately 3 days Dose should be adjusted in patients with reduced renal function ( 2.3 , 2.4 ) 2.1 Dosage for Postherpetic Neuralgia In adults with postherpetic neuralgia, RELGAABI may be initiated on Day 1 as a single 300 mg dose, on Day 2 as 600 mg/day (300 mg two times a day), and on Day 3 as 900 mg/day (300 mg three times a day). The dose can subsequently be titrated up as needed for pain relief to a dose of 1800 mg/day (600 mg three times a day). In clinical studies, efficacy was demonstrated over a range of doses from 1800 mg/day to 3600 mg/day with comparable effects across the dose range; however, in these clinical studies, the additional benefit of using doses greater than 1800 mg/day was not demonstrated. 2.2 Dosage for Epilepsy with Partial Onset Seizures Patients 12 Years of Age and Above The starting dose is 300 mg three times a day. The recommended maintenance dose of RELGAABI is 300 mg to 600 mg three times a day. Dosages up to 2,400 mg/day have been administered in long-term clinical studies. Doses of 3,600 mg/day have also been administered to a small number of patients for a relatively short duration. Administer RELGAABI three times a day using 300 mg or 400 mg capsules. The maximum time between doses should not exceed 12 hours. Pediatric Patients Age 3 to 11 Years The starting dose range is 10 mg/kg/day to 15 mg/kg/day, given in three divided doses, and the recommended maintenance dose reached by upward titration over a period of approximately 3 days. The recommended maintenance dose of RELGAABI in patients 3 to 4 years of age is 40 mg/kg/day, given in three divided doses. The recommended maintenance dose of RELGAABI in patients 5 to 11 years of age is 25 mg/kg/day to 35 mg/kg/day, given in three divided doses. RELGAABI may be administered as capsule, or tablet, or using combinations of these formulations. Dosages up to 50 mg/kg/day have been administered in a long-term clinical study. The maximum time interval between doses should not exceed 12 hours. 2.3 Dosage Adjustment in Patients with Renal Impairment Dosage adjustment in patients 12 years of age and older with renal impairment or undergoing hemodialysis is recommended, as follows (see dosing recommendations above for effective doses in each indication): TABLE 1. RELGAABI Dosage Based on Renal Function TID = Three times a day; BID = Two times a day; QD = Single daily dose a For patients with creatinine clearance 30 to 59 400 to 1,400 200 BID 300 BID 400 BID 500 BID 700 BID > 15 to 29 200 to 700 200 QD 300 QD 400 QD 500 QD 700 QD 15 a 100 to 300 100 QD 125 QD 150 QD 200 QD 300 QD Post-Hemodialysis Supplemental Dose (mg) b Hemodialysis 125 b 150 b 200 b 250 b 350 b Creatinine clearance (CLCr) is difficult to measure in outpatients. In patients with stable renal function, creatinine clearance can be reasonably well estimated using the equation of Cockcroft and Gault: The use of RELGAABI in patients less than 12 years of age with compromised renal function has not been studied. image-04 2.4 Dosage in Elderly Because elderly patients are more likely to have decreased renal function, care should be taken in dose selection, and dose should be adjusted based on creatinine clearance values in these patients. 2.5 Administration Information Administer RELGAABI orally with or without food. RELGAABI capsules should be swallowed whole with water. If the RELGAABI dose is reduced, discontinued, or substituted with an alternative medication, this should be done gradually over a minimum of 1 week (a longer period may be needed at the discretion of the prescriber).

Warnings and cautions 5 WARNINGS AND PRECAUTIONS

Monitoring

  • 5 WARNINGS AND PRECAUTIONS Drug Reaction with Eosinophilia and Systemic Symptoms (Multiorgan hypersensitivity): Discontinue if alternative etiology is not established ( 5.1 ) Anaphylaxis and Angioedema: Discontinue and evaluate patient immediately ( 5.2 ) Driving Impairment; Somnolence/Sedation and Dizziness: Warn patients not to drive until they have gained sufficient experience to assess whether their ability to drive or operate heavy machinery will be impaired ( 5.3 , 5.4 ) Suicidal Behavior and Ideation: Monitor for suicidal thoughts/behavior ( 5.5 ) Abrupt or rapid discontinuation may increase the risk for seizures.
  • Withdrawal symptoms, or suicidal behavior and ideation have been observed after discontinuation ( 5.6 ) Respiratory Depression: May occur with RELGAABI when used with concomitant central nervous system (CNS) depressants, including opioids, or in the setting of underlying respiratory impairment.
  • Monitor patients and adjust dosage as appropriate ( 5.8 ) Neuropsychiatric Adverse Reactions in Children 3 to 12 Years of Age: Monitor for such events ( 5.9 ) 5.1 Drug Reaction with Eosinophilia and Systemic Symptoms (DRESS)/Multiorgan Hypersensitivity Drug Reaction with Eosinophilia and Systemic Symptoms (DRESS), also known as multiorgan hypersensitivity, has occurred with RELGAABI.
  • Some of these reactions have been fatal or life-threatening.

Interaction Notes

  • 7 DRUG INTERACTIONS Concentrations increased by morphine; may need dose adjustment ( 5.4 , 7.1 ) 7.1 Opioids Respiratory depression and sedation, sometimes resulting in death, have been reported following coadministration of gabapentin with opioids (e.g., morphine, hydrocodone, oxycodone, buprenorphine) [see Warnings and Precautions (5.8) ].
  • Hydrocodone Coadministration of RELGAABI with hydrocodone decreases hydrocodone exposure [see Clinical Pharmacology (12.3) ] .
  • The potential for alteration in hydrocodone exposure and effect should be considered when RELGAABI is started or discontinued in a patient taking hydrocodone.
  • Morphine When gabapentin is administered with morphine, patients should be observed for signs of CNS depression, such as somnolence, sedation and respiratory depression [see Clinical Pharmacology (12.3) ].
