For topical dermatologic use only. Not for ophthalmic, oral, or intravaginal use.
Wash hands before and after application. Use gloves if required by universal precautions. Apply sparingly in a thin film and rub gently into affected area(s) of clean, dry skin. Restrict application to the affected areas and try to avoid normal surrounding skin.
Patients who fail to respond to topical treatment after 1—4 weeks should be re-evaluated.
Topical preparations containing steroids generally should not be used with occlusive dressings. Instruct patients not to bandage, cover, or wrap area in any way that may be occlusive, unless directed by prescriber.

Nystatin and triamcinolone are used together topically for short-term (< 2 weeks) treatment of candidal skin infections. Nystatin is an antifungal agent and triamcinolone is a corticosteroid used for its antiinflammatory, vasoconstrictive, and antipruritic properties. Compared to nystatin or triamcinolone alone, the combination has been shown to provide faster and more pronounced clearing of erythema and pruritus, especially in the first few days of treatment.

Mechanism of Action:•Nystatin: Nystatin binds to sterols in fungal cell membranes. As a result of this binding, membrane integrity of fungal cells is impaired, causing the loss of intracellular potassium and other cellular contents. Nystatin is ineffective against bacteria because they do not contain sterols in their cell membranes. Nystatin is also ineffective against protozoa, trichomonads, and viruses.•Triamcinolone: At the cellular level, corticosteroids induce peptides called lipocortins. Lipocortins antagonize phospholipase A2, an enzyme which causes the breakdown of leukocyte lysosomal membranes to release arachidonic acid. This action decreases the formation and release of endogenous inflammatory mediators including prostaglandins, kinins, histamine, liposomal enzymes and the complement system. Early anti-inflammatory effects of topical corticosteroids include the inhibition of macrophage and leukocyte movement and activity in the inflamed area by reversing vascular dilation and permeability. Later inflammatory processes such as capillary production, collagen deposition, keloid (scar) formation also are inhibited by corticosteroids. Clinically, these actions correspond to decreased edema, erythema, pruritus, plaque formation and scaling of the affected skin.

Nystatin; triamcinolone is applied topically to the skin.
 
Nystatin: Nystatin is not systemically absorbed from intact skin or mucous membranes.
Triamcinolone: Any triamcinolone that reaches the systemic circulation is metabolized by the liver to inactive metabolites. These inactive metabolites, as well as a small portion of unchanged drug, are excreted in the urine

There are no adequate and well-controlled studies regarding use of nystatin; triamcinolone topical formulations during human pregnancy, and it is unknown if the drug causes fetal harm or affect reproductive capacity. Some potent topical corticosteroids have been shown to be teratogenic in laboratory animals; therefore, the drug should not be used in large amounts, on large areas, or for prolonged periods of time in pregnant women. Administer during pregnancy only if the benefit to the mother justifies the potential risk to the infant.

Although corticosteroids are known to be excreted in breast milk, data regarding use of nystatin; triamcinolone during breast-feeding are limited. Recommendations from the American Academy of Pediatrics (AAP) on the use of triamcinolone in lactating women are not available; however, the AAP considers other corticosteroids, such as prednisone and prednisolone, to be usually compatible with breast-feeding. The manufacturer advises caution if administering the drug to breast-feeding women. To limit a nursing infants potential exposure, instruct women not to apply on the breast immediately prior to nursing. Consider the benefits of breast-feeding, the risk of potential infant drug exposure, and the risk of an untreated or inadequately treated condition. If a breast-feeding infant experiences an adverse effect related to a maternally administered drug, health care providers are encouraged to report the adverse effect to the FDA.
