Cautions
- Neomycin sensitization, including itching, reddening, edema, and failure to heal may occur; discontinue therapy if it occurs
- The solution does not penetrate quite as well as the suspension does
- Systemic absorption of topical corticosteroids may cause hypothalamic-pituitary-adrenal axis suppression, which may lead to adrenal crisis, especially in children and in patients receiving large doses for prolonged periods
- Prolonged use of corticosteroids may increase the incidence of secondary infection, mask acute infection, and may also prolong or exacerbate viral infections
- Development of Kaposi sarcoma-associated with prolonged treatment with corticosteroids; discontinue therapy if it occurs
- Neomycin can induce permanent sensorineural hearing loss due to cochlear damage, including the destruction of hair cells in the organ of Corti; the risk of ototoxicity is greater with prolonged use
- Percutaneous absorption of topical corticosteroids may occur, which may cause manifestations of hyperglycemia, Cushing syndrome, or glycosuria; use of occlusive dressings, application of denuded skin, or application to large surface areas may increase the risk of absorption
Pregnancy and Lactation
- Use with caution if the benefits outweigh the risks during pregnancy.
- Lactation
- Unknown whether a drug is excreted in the milk; use with caution
