Dosing in kidney impairment
Dosage Adjustment in Renal Impairment In patients with moderate renal impairment (creatinine clearance of 30 to 59 mL/min), administer SUSTOL on Day 1 of chemotherapy and not more frequently than once every 14 days. Avoid SUSTOL in patients with severe renal impairment (creatinine clearance of less than 30 mL/min) [see Use in Specific Populations] .

Important Administration Instructions For subcutaneous injection only. SUSTOL is intended for administration by a health care provider. SUSTOL is supplied as a refrigerated kit consisting of a single-dose, pre-filled, sterile syringe, a special thin walled 18 Ga 5/8" administration needle, two syringe warming pouches, and a Point Lok ® needle protection device.
See the SUSTOL Instructions for Use included in the kit for complete administration instructions with illustrations. Do not substitute non-kit components for any of the components from the kit for administration. Preparation At least 60 minutes prior to administration, remove the SUSTOL kit from refrigeration. Unpack the kit to allow the SUSTOL syringe and all other contents to warm to room temperature.
Activate one of the syringe warming pouches, and wrap the SUSTOL syringe in the warming pouch for 5 to 6 minutes to warm SUSTOL to body temperature. Prior to administration, inspect the SUSTOL syringe visually for particulate matter and discoloration. Note that the syringe is amber colored glass. SUSTOL should not be administered if particulate matter or discoloration is observed, the tip cap is missing or has been tampered with, or if the Luer fitting is missing or dislodged.
Administration Use standard aseptic technique when performing the injection. Administer SUSTOL as a single subcutaneous injection in the skin of the back of the upper arm or in the skin of the abdomen at least one inch away from the umbilicus. Avoid injecting SUSTOL anywhere the skin is burned, hardened, inflamed, swollen, or otherwise compromised [see Warnings and Precautions] .
Topical anesthetic may be used at the injection site prior to administration of SUSTOL. Due to the viscosity of SUSTOL, the time required for injection is greater than most medications administered subcutaneously. SUSTOL requires a slow, sustained injection which may take up to 20 to 30 seconds . Pressing the plunger harder will NOT expel SUSTOL faster.

7 DRUG INTERACTIONS
7.1 Serotonergic Drugs Serotonin syndrome (including altered mental status, autonomic instability, and neuromuscular symptoms) has been described following the concomitant use of 5-HT 3 receptor antagonists and other serotonergic drugs, including selective serotonin reuptake inhibitors (SSRIs) and serotonin and noradrenaline reuptake inhibitors (SNRIs). Monitor for the emergence of serotonin syndrome. If symptoms occur, discontinue SUSTOL and initiate supportive treatment [see Warnings and Precautions ( 5.4 )] .
Contraindications
4 CONTRAINDICATIONS SUSTOL is contraindicated in patients with hypersensitivity to granisetron, any of the components of SUSTOL, or to any of the other 5-HT 3 receptor antagonists [see Warnings and Precautions ( 5.3 ), Description ( 11 )] . Hypersensitivity to granisetron, any of the components of SUSTOL, or to any of the other 5-HT 3 receptor antagonists. ( 4 , 5.3 )

Pregnancy
8.1 Pregnancy Risk Summary There are no available data on the use of SUSTOL in pregnant women. Limited published data on granisetron use during pregnancy are not sufficient to inform a drug-associated risk. In animal reproduction studies, no adverse developmental effects were observed in pregnant rats and rabbits administered granisetron hydrochloride during organogenesis at intravenous doses up to 61 times and 41 times respectively the maximum recommended human dose (MRHD) of SUSTOL 10 mg/week [see Data] . The estimated background risk of major birth defects and miscarriage for the indicated population is unknown.
All pregnancies have a background risk of birth defect, loss, or other adverse outcomes. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2 to 4% and 15 to 20%, respectively.
Data Animal Data Reproduction studies with granisetron hydrochloride have been performed in pregnant rats following administration during the period of organogenesis at intravenous doses up to 9 mg/kg/day (approximately 61 times the maximum recommended human dose (MRHD) of SUSTOL 10 mg/week, based on body surface area) and oral doses up to 125 mg/kg/day (approximately 851 times the MRHD of SUSTOL 10 mg/week, based on body surface area).
Reproduction studies have been performed in pregnant rabbits in which granisetron hydrochloride was administered during the period of organogenesis at intravenous doses up to 3 mg/kg/day (approximately 41 times the MRHD of SUSTOL 10 mg/week, based on body surface area) and at oral doses up to 32 mg/kg/day (approximately 436 times the MRHD of SUSTOL 10 mg/week, based on body surface area). These studies did not reveal any evidence of impaired fertility or harm to the fetus due to granisetron hydrochloride.
Reproduction studies with the polymer vehicle for SUSTOL have been performed in pregnant rats and rabbits following administration of the polymer vehicle during the period of organogenesis at subcutaneous doses up to 0.295 and 1.18 g per day, respectively, (approximately 45 and 36 times, respectively the amount of polymer vehicle present in the maximum recommended /weekly single human dose of SUSTOL, based on body surface area). These studies did not reveal any evidence of impaired fertility or harm to the fetus due to the polymer vehicle.
A pre and postnatal development study with the polymer vehicle for SUSTOL in rats showed no evidence of any adverse effects on pre and postnatal development at subcutaneous doses (administered on gestation days…
