Across FDA labelling, products containing GABAPENTIN are most often described in connection with: gralise indicated, management postherpetic, gabapentin products, differing pharmacokinetic, frequency administration, neuralgia phn, important limitation, see warnings. Wording differs between labels, and the full indications section on this page takes precedence when it is present.

1 INDICATIONS AND USAGE GRALISE is indicated for the management of postherpetic neuralgia. GRALISE is not substitutable with other gabapentin products because of differing pharmacokinetic profiles that affect the frequency of administration. GRALISE is indicated for the management of Postherpetic Neuralgia (PHN). Important Limitation: GRALISE is not substitutable with other gabapentin products because of differing pharmacokinetic profiles that affect the frequency of administration (See Warnings and Precautions )

2 DOSAGE AND ADMINISTRATION GRALISE should be titrated to an 1,800 mg dose taken orally, once-daily, with the evening meal. GRALISE tablets should be swallowed whole. Do not crush, split, or chew the tablets. ( 2.1 ) If GRALISE dose is reduced, discontinued, or substituted with an alternative medication, this should be done gradually over a minimum of 1 week or longer (at the discretion of the prescriber). ( 2.1 ) Renal impairment: Dose should be adjusted in patients with reduced renal function. GRALISE should not be used in patients with CrCl less than 30 or in patients on hemodialysis. ( 2.2 ) 2.1 Postherpetic Neuralgia Do not use GRALISE as a substitute for other gabapentin products. Titrate GRALISE to an 1,800 mg dose taken orally once daily with the evening meal. GRALISE tablets should be swallowed whole. Do not split, crush, or chew the tablets. If GRALISE dosing is reduced, discontinued, or substituted with an alternative medication, this should be done gradually over a minimum of one week or longer (at the discretion of the prescriber). In adults with postherpetic neuralgia, GRALISE therapy should be initiated and titrated as follows: Table 1: GRALISE Recommended Titration Schedule Day 1 Day 2 Days 3-6 Days 7-10 Days 11-14 Day 15 Daily Dose 300 mg 600 mg 900 mg 1,200 mg 1,500 mg 1,800 mg 2.2 Patients with Renal Impairment In patients with stable renal function, creatinine clearance (C Cr ) can be reasonably well estimated using the equation of Cockcroft and Gault: For females C Cr =(0.85)(140-age)(weight)/[(72)(S Cr )] For males C Cr =(140-age)(weight)/[(72)(S Cr )] where age is in years, weight is in kilograms and S Cr is serum creatinine in mg/dL. The dose of GRALISE should be adjusted in patients with reduced renal function, according to Table 2. Patients with reduced renal function must initiate GRALISE at a daily dose of 300 mg. GRALISE should be titrated following the schedule outlined in Table 1. Daily dosing in patients with reduced renal function must be individualized based on tolerability and desired clinical benefit. Table 2: GRALISE Dosage Based on Renal Function Once-daily dosing Creatinine Clearance (mL/min) GRALISE Dose (once daily with evening meal) ≥ 60 1,800 mg 30 - 60 600 mg to 1,800 mg < 30 GRALISE should not be administered patients receiving hemodialysis GRALISE should not be administered

4 CONTRAINDICATIONS GRALISE is contraindicated in patients with demonstrated hypersensitivity to the drug or its ingredients. GRALISE is contraindicated in patients who have demonstrated hypersensitivity to the drug or its ingredients. ( 4 )

6 ADVERSE REACTIONS The following adverse reactions are described elsewhere in the labeling: Suicidal Behavior and Ideation [see Warnings and Precautions ( 5.1 )] Increased Risk of Adverse Reactions with Abrupt or Rapid Discontinuation [see Warnings and Precautions ( 5.2 )] Respiratory Depression [see Warnings and Precautions ( 5.3 )] Tumorigenic Potential [see Warnings and Precautions ( 5.4 )] Drug Reaction with Eosinophilia and Systemic Symptoms (DRESS)/Multiorgan Hypersensitivity [see Warnings and Precautions ( 5.5 )] Laboratory Tests [see Warnings and Precautions ( 5.6 )] The most common adverse reaction (greater than or equal to 5% and twice placebo) is dizziness.

A total of 359 patients with neuropathic pain associated with postherpetic neuralgia have received GRALISE at doses up to 1,800 mg daily during placebo-controlled clinical studies. In clinical trials in patients with postherpetic neuralgia, 9.7% of the 359 patients treated with GRALISE and 6.9% of 364 patients treated with placebo discontinued prematurely due to adverse reactions. In the GRALISE treatment group, the most common reason for discontinuation due to adverse reactions was dizziness. Of GRALISE-treated patients who experienced adverse reactions in clinical studies, the majority of those adverse reactions were either "mild" or "moderate". Table 4 lists all adverse reactions, regardless of causality, occurring in at least 1% of patients with neuropathic pain associated with postherpetic neuralgia in the GRALISE group for which the incidence was greater than in the placebo group. Table 4: Treatment-Emergent Adverse Reaction Incidence in Controlled Trials in Neuropathic Pain Associated with Postherpetic Neuralgia (Events in at Least 1% of all GRALISE-Treated Patients and More Frequent Than in the Placebo Group) Body System - Preferred Term GRALISE N = 359 % Placebo N = 364 % Ear and Labyrinth Disorders Vertigo 1.4 0.5 Gastrointestinal Disorders Diarrhea 3.3 2.7 Dry mouth 2.8 1.4 Constipation 1.4 0.3 Dyspepsia 1.4 0.8 General Disorders Peripheral edema 3.9 0.3 Pain 1.1 0.5 Infections and Infestations Nasopharyngitis 2.5 2.2 Urinary tract infection 1.7 0.5 Investigations Weight increased 1.9 0.5 Musculoskeletal and Connective Tissue Disorders Pain in extremity 1.9 0.5 Back pain 1.7 1.1 Nervous System Disorders Dizziness 10.9 2.2 Somnolence 4.5 2.7 Headache 4.2 4.1 Lethargy 1.1 0.3 In addition to the adverse reactions reported in Table 4 above, the following adverse reactions with an uncertain relationship to GRALISE were reported during the clinical development for the treatment of postherpetic neuralgia. Events in more than 1% of patients but equally or more frequently in the GRALISE-treated patients than in the placebo group included blood pressure increase, confusional state, gastroenteritis viral, herpes zoster, hypertension, joint swelling, memory impairment, nausea, pneumonia, pyrexia, rash, seasonal allergy, and upper respiratory infection. 6.2 Postmarketing and Other Experience with other Formulations of Gabapentin In addition to the adverse experiences reported during clinical testing of gabapentin, the following adverse experiences have been reported in patients receiving other formulations of marketed gabapentin. These adverse experiences have not been listed above and data are insufficient to support an estimate of their incidence or to establish causation. The listing is alphabetized: angioedema, blood glucose fluctuation, breast enlargement, bullous pemphigoid, elevated creatine kinase, elevated liver function tests, erythema multiforme, fever, hyponatremia, jaundice, movement disorder, Stevens-Johnson syndrome. There are postmarketing reports of withdrawal symptoms after discontinuation of gabapentin. Reported adverse reactions include, but are not limited to, seizures, depression, suicidal ideationand behavior, agitation, confusion, disorientation, psychotic symptoms, anxiety, insomnia, nausea, pain, sweating, tremor, headache, dizziness, and malaise [see Warnings and Precautions( 5.2 )] . There are postmarketing reports of life-threatening or fatal respiratory depression in patients taking gabapentin with opioids or other central nervous system (CNS) depressants, or in the setting of underlying respiratory impairment.
