Concerns related to adverse effects:
• CNS effects: May cause drowsiness and/or blurred vision, which may impair physical or mental abilities; patients must be cautioned about performing tasks which require mental alertness (eg, operating machinery or driving).
• Diarrhea: May be a sign of incomplete intestinal obstruction; discontinue treatment if this occurs.
• Heat prostration: May occur in the presence of increased environmental temperature; use caution in hot weather and/or exercise.
• Cardiovascular disease: Use with caution in patients with coronary artery disease, tachyarrhythmias, heart failure, or hypertension.
• Hepatic impairment: Use with caution in patients with hepatic impairment.
• Hiatal hernia: Use with caution in patients with hiatal hernia with reflux esophagitis.
• Hyperthyroidism: Use with caution in patients with hyperthyroidism.
• Neuropathy: Use with caution in patients with autonomic neuropathy.
• Renal impairment: Use with caution in patients with renal impairment.
• Ulcerative colitis: Use with caution in patients with ulcerative colitis; large doses may suppress intestinal motility.
Concurrent drug therapy issues:
• Drug-drug interactions: Potentially significant interactions may exist, requiring dose or frequency adjustment, additional monitoring, and/or selection of alternative therapy. Consult drug interactions database for more detailed information.
• Elderly: Use with caution.
Dosage form specific issues:
• Polysorbate 80: Some dosage forms may contain polysorbate 80 (also known as Tweens). Hypersensitivity reactions, usually a delayed reaction, have been reported following exposure to pharmaceutical products containing polysorbate 80 in certain individuals (Isaksson 2002; Lucente 2000; Shelley 1995). Thrombocytopenia, ascites, pulmonary deterioration, and renal and hepatic failure have been reported in premature neonates after receiving parenteral products containing polysorbate 80 (Alade 1986; CDC 1984). See manufacturer’s labeling.
• Propylene glycol: Some dosage forms may contain propylene glycol; large amounts are potentially toxic and have been associated with hyperosmolality, lactic acidosis, seizures and respiratory depression; use caution (AAP 1997; Zar 2007). See manufacturer’s labeling.

Animal reproduction studies have not been conducted.
• Discuss specific use of drug and side effects with patient as it relates to treatment. (HCAHPS: During this hospital stay, were you given any medicine that you had not taken before? Before giving you any new medicine, how often did hospital staff tell you what the medicine was for? How often did hospital staff describe possible side effects in a way you could understand?)
• Patient may experience fatigue, dizziness, headache, nausea, vomiting, dry mouth, loss of strength and energy, change in taste, anxiety, or insomnia. Have patient report immediately to prescriber muscle weakness, tachycardia, abnormal heartbeat, confusion, bloating, vision changes, sexual dysfunction, diarrhea, urinary retention, lack of sweat, or severe constipation (HCAHPS).
• Educate patient about signs of a significant reaction (eg, wheezing; chest tightness; fever; itching; bad cough; blue skin color; seizures; or swelling of face, lips, tongue, or throat). Note: This is not a comprehensive list of all side effects. Patient should consult prescriber for additional questions.

This information is intended to serve as a concise initial reference for health care professionals to use when discussing medications with a patient. You must ultimately rely on your own discretion, experience, and judgment in diagnosing, treating, and advising patients.
