Concerns related to adverse effects:
• Hypersensitivity: Hypersensitivity reactions (eg, angioedema, dyspnea, eye swelling, facial swelling, skin reactions, urticaria) have been reported; discontinue use if signs/symptoms occur.
• Hypopigmentation: A few cases of hypopigmentation after use have been reported; monitor for changes in skin color, especially in patients with dark complexions.
• Skin irritation: Skin irritation (eg, pruritus, burning, stinging) may occur, usually during the first few weeks of therapy. Discontinue use if severe skin irritation or sensitivity occurs.
Disease-related concerns:
• Asthma: Exacerbation of asthma has been reported.
Dosage form specific issues:
• Foam: Contains flammable propellants. Avoid fire, flame and smoking during and immediately following use.
• Gel: Reassess use if no improvement is seen after 12 weeks of therapy.
• 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.
Other warnings/precautions:
• Appropriate use: For external use only; not for oral, ophthalmic, or vaginal use; avoid contact with the eyes, mouth, and other mucous membranes. Use of occlusive dressings or wrappings should be avoided.
Some dosage forms may contain propylene glycol; in neonates large amounts of propylene glycol delivered orally, intravenously (eg, >3,000 mg/day), or topically have been associated with potentially fatal toxicities which can include metabolic acidosis, seizures, renal failure, and CNS depression; toxicities have also been reported in children and adults including hyperosmolality, lactic acidosis, seizures and respiratory depression; use caution (AAP 1997; Shehab 2009).
