Warnings
Contraindications
Hypersensitivity to drug or excipients
Cautions
Liver disease
Protect patch from sunlight
May prolong QT interval; coadministration with drugs known to prolong QT interval may result in serious arrhythmias
Mild application site reactions have occurred; remove patch if severe reactions or generalized skin reaction occur
Avoid exposing granisetron patch and surrounding area to direct external heat sources, such as heating pads; plasma concentration continues to increase during period of heat exposure
Gastrointestinal disorders
- Hospitalization due to constipation or fecal impaction reported; monitor patients for development of constipation while receiving treatment taking into consideration the extended-release properties of the injection formulation over at least 5 to 7 days, particularly in patients receiving opioid medications; consider optimizing bowel regimens in patients receiving injection formulation
- Therapy may mask a progressive ileus and/or gastric distention; this should be particularly considered before use in patients who have had recent abdominal surgery; monitor for decreased bowel activity, particularly in patients with risk factors for gastrointestinal obstruction
Injection site reactions (ISRs)
- Infections at the injection site may occur; in cancer patients; patients with infection treated with antibiotics have had complete resolution
- Bruising and/or hematomas at the injection site reported; bruising and/or hematomas (eg, greater than 4 cm bruise or hematoma) with a delayed onset also reported; severe bruising or hematoma reported in 3% of patients; patients receiving concomitant anticoagulant and antiplatelet medications reported to be at greater risk for severe injection site bruising and hematomas
Bleeding at injection site and for longer than 5 days reported
- Pain and/or tenderness severe enough to require taking pain medication, interfere with patient activity level, or cause significant discomfort at rest reported; among all patients who reported pain and/or tenderness, the median duration was 5 days; pain lasting longer than 7 days reported in some patients
- Nodules at injection site reported; nodules persisting for a median of 15 days and patients that had nodules with durations longer than 21 days reported
Management of injection site reactions
- Monitor patients for ISRs following injection; some ISRs (infections, bruising, and hematoma) may occur up to 2 weeks or more after injection administration.
- In patients receiving antiplatelet agents or anticoagulants, consider increased risk of bruising or severe hematoma prior to use of this medication
- In patients with ongoing or unresolved ISRs, administer at a site away from areas affected by ISRs
Hypersensitivity
- Hypersensitivity reactions, including anaphylaxis, reported in granisetron-treated patients who have exhibited hypersensitivity to other 5-HT3 receptor antagonists; avoid therapy in patients who have had hypersensitivity reactions to other 5-HT3 receptor antagonists
- Due to extended-release properties of the subcutaneous formulation, exposure to granisetron may continue for 5 to 7 days following administration; hypersensitivity reactions may occur up to 7 days or longer following administration this formulation and may have an extended course
- Inform patients of signs and symptoms of anaphylaxis, and instruct them to seek immediate medical care should signs and symptoms occur; if hypersensitivity reactions occur, administer appropriate treatment and monitor patients until signs and symptoms resolve
Serotonin syndrome
- Serotonin syndrome reported with 5-HT3 receptor antagonists; most reports have been associated with concomitant use of serotonergic drugs (eg, selective serotonin reuptake inhibitors (SSRIs), serotonin and norepinephrine reuptake inhibitors (SNRIs), monoamine oxidase inhibitors, mirtazapine, fentanyl, lithium, tramadol, and intravenous methylene blue); some of the reported cases were fatal
- Serotonin syndrome occurring with overdose of another 5-HT3 receptor antagonist alone also reported; the majority of reports of serotonin syndrome related to 5-HT3 receptor antagonist use occurred in a post-anesthesia care unit or an infusion center
- Symptoms associated with serotonin syndrome may include the following combination of signs and symptoms, mental status changes (eg, agitation, hallucinations, delirium, and coma), autonomic instability (eg, tachycardia, labile blood pressure, dizziness, diaphoresis, flushing, hyperthermia), neuromuscular symptoms (eg, tremor, rigidity, myoclonus, hyperreflexia, incoordination), seizures, with or without gastrointestinal symptoms (eg, nausea, vomiting, diarrhea)
- Patients should be monitored for emergence of serotonin syndrome, especially with concomitant use of this medication and other serotonergic drugs; if symptoms of serotonin syndrome occur, discontinue therapy and initiate supportive treatment; patients should be informed of increased risk of serotonin syndrome, especially if this medication is used concomitantly with other serotonergic drugs
Pregnancy & Lactation
Pregnancy
There are no available data on use in pregnant women; limited published data on granisetron use during pregnancy are not sufficient to inform a drug-associated risk
Animal data
- In animal reproduction studies, no adverse developmental effects were observed in pregnant rats and rabbits administered granisetron hydrochloride during organogenesis
Lactation
There are no data on presence of the drug in human milk, effects on breastfed infant, or on milk production; the lack of clinical data during lactation precludes a clear determination of the risk of the drug to an infant during lactation; therefore, developmental and health benefits of breastfeeding should be considered along with mother’s clinical need for therapy and any potential adverse effects on breastfed infant from the drug or from the underlying maternal condition
Pregnancy Categories
A: Generally acceptable. Controlled studies in pregnant women show no evidence of fetal risk.
B: May be acceptable. Either animal studies show no risk but human studies not available or animal studies showed minor risks and human studies done and showed no risk. C: Use with caution if benefits outweigh risks. Animal studies show risk and human studies not available or neither animal nor human studies done. D: Use in LIFE-THREATENING emergencies when no safer drug available. Positive evidence of human fetal risk. X: Do not use in pregnancy. Risks involved outweigh potential benefits. Safer alternatives exist. NA: Information not available.Pharmacology

Syringe: dexamethasone sodium phosphate, methylprednisolone sodium succinate
Y-site (partial list): allopurinol, amphotericin B cholSO4, ampicillin, butorphanol, carboplatin, cisplatin, cytarabine, dactinomycin, docetaxel, diphenhydramine, etoposide, famotidine, fluorouracil, furosemide, fluconazole, heparin, hydromorphone, linezolid, lorazepam, MgSO4, meoperidine, morphine, metoclopramide, metronidazole, paclitaxel, KCl, prochlorperazine, promethazine, Na-bicarb, thiotepa, vincristine, vancomycin
IV Preparation
IV infusion: dilute to 20-50 mL with D5W or NS
IV Administration
IVP undiluted over 30 sec, or
IV infusion over 5 min after dilution to 20-50 mL with D5W or NS
SC Preparation (Sustol)
At least 60 minutes before administration, remove kit from refrigerator
Unpack the kit to allow the Sustol syringe and all other contents to warm to room temperature
Activate 1 of the syringe warming pouches, and wrap the syringe in the warming pouch for 5-6 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
Do not administered if particulate matter or discoloration observed, the tip cap is missing or has been tampered with, or if the Luer fitting is missing or dislodged
SC Administration (Sustol)
For SC injection only
Intended for administration by a health care provider
Use standard aseptic technique when performing the SC injection
Administer as a single SC injection in the back of the upper arm or in the skin of the abdomen at least 1-inch away from the umbilicus
Avoid injecting anywhere the skin is burned, hardened, inflamed, swollen, or otherwise compromised
Topical anesthetic may be used at the injection site prior to administration
Due to the viscosity of the liquid, the time required for injection is greater than most medications administered SC; requires a slow, sustained injection which may take up to 20-30 seconds
Pressing the plunger harder will NOT expel the viscous liquid faster
