About Neo-Synalar

What is this medication? Neo-Synalar is a prescription topical medication that contains two primary active ingredients: fluocinolone acetonide and neomycin sulfate. Fluocinolone belongs to a class of drugs known as corticosteroids, which work by reducing the swelling, redness, and itching caused by various skin conditions. Neomycin is an aminoglycoside antibiotic that prevents or treats bacterial infections that may occur in irritated skin.

This medication is specifically used to treat inflammatory skin disorders such as eczema, psoriasis, and various types of dermatitis when a secondary bacterial infection is present or suspected. By combining an anti-inflammatory agent with an antibiotic, Neo-Synalar addresses both the underlying skin irritation and the complicating infection simultaneously. It is intended for external use only and should be applied to the skin exactly as directed by a healthcare provider to avoid potential side effects.

Prescribing information

From the FDA-approved label for Neo-Synalar. Official source: DailyMed (NLM) · Label effective Mar 18, 2026

Indications and usage
INDICATIONS AND USAGE NEO-SYNALAR ® cream is indicated for the treatment of corticosteroid-responsive dermatoses with secondary infection. It has not been demonstrated that this steroid-antibiotic combination provides greater benefit than the steroid component alone after 7 days of treatment (see WARNINGS section) .
Dosage and administration
DOSAGE AND ADMINISTRATION NEO-SYNALAR ® cream is generally applied to the affected area as a thin film from two to four times daily depending on the severity of the condition. Since NEO-SYNALAR ® cream is a water-washable vanishing cream, it is easily applied and leaves no traces.
Contraindications
CONTRAINDICATIONS Topical corticosteroids are contraindicated in those patients with a history of hypersensitivity to any of the components of the preparation. This product should not be used in the external auditory canal if the eardrum is perforated.
Warnings
WARNINGS If local infection should continue or become severe, or in the presence of systemic infection, appropriate systemic antibacterial therapy, based on susceptibility testing, should be considered. Because of the concern of nephrotoxicity and ototoxicity associated with neomycin, this combination product should not be used over a wide area or for extended periods of time. There are articles in the current medical literature that indicate an increase in the prevalence of persons sensitive to neomycin.
Adverse reactions
ADVERSE REACTIONS The following local adverse reactions are reported infrequently with topical corticosteroids. These reactions are listed in an approximate decreasing order of occurrence: Burning Hypertrichosis Maceration of the skin Itching Acneiform eruptions Secondary infection Irritation Hypopigmentation Skin atrophy Dryness Perioral dermatitis Striae Folliculitis Allergic contact dermatitis Miliaria The following adverse reactions have been reported with the topical use of neomycin: Ototoxicity Nephrotoxicity
Use in pregnancy
Pregnancy Corticosteroids are generally teratogenic in laboratory animals when administered systemically at relatively low dosage levels. The more potent corticosteroids have been shown to be teratogenic after dermal application in laboratory animals. There are no adequate and well-controlled studies in pregnant women on teratogenic effects from topically applied corticosteroids. Therefore, topical corticosteroids should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus. Drugs of this class should not be used extensively on pregnant patients, in large amounts, or for prolonged periods of time.
