Patient Medication Information: uses, side effects, how to take - Viaderm Kc Crm
WARNINGS AND PRECAUTIONS
General
Patients should be advised to inform subsequent physicians of the prior use of corticosteroids. Viaderm K.C.® Cream and Viaderm K.C.® Ointment should not be used under occlusive dressings (see ADVERSE REACTIONS).
Cardiovascular
Topical corticosteroids should be used with caution in patients with stasis dermatitis and other skin diseases associated with impaired circulation. If a symptomatic response is not noted within 7 days, the patient should be re-evaluated. Prolonged use of topical antibiotics should be avoided.
Endocrine and Metabolism
Although adrenal suppression and other systemic adverse effects are rare with topical corticosteroid preparations, their possible occurrence must be kept in mind, particularly when these preparations are used over large areas or for an extended period of time. Prolonged use may lead to steroid withdrawal when the medication is discontinued.
Because of the potential hazard of nephrotoxicity and ototoxicity, avoid prolonged use or the use of large amounts in the treatment of skin infections following burns, tropic ulceration and other conditions when absorption of neomycin is possible.
Gramicidin absorption following topical administration is unlikely; however, hemolysis may occur should the drug enter the blood. If gramicidin is allowed in close proximity to the sub-arachnoid space, a chemical arachnoiditis may occur (see ADVERSE REACTIONS).
Ophthalmologic
Topical corticosteroids should be used with caution on lesions close to the eye. Posterior subcapsular cataracts have been observed following systemic corticosteroid therapy (see ADVERSE REACTIONS).
Sensitivity
Hypensitivity of nystatin is extremely uncommon. Sensitivity reactions following the topical use of gramicidin or triamcinolone acetonide are rarely encountered. Burning, itching, irritation, dryness, erythema, folliculitis, hypertrichosis, acnelform eruptions, tinnitus, deafness and hypopigmentation have been reported with topical corticosteroids.
An increase in the incidence of patients allergic to neomycin has been reported in literature.
Neomycin itself may cause an allergic otitis extema. Systemic neomycin toxicity has occurred rarely following topical administration; tinnitus and deafness have been reported (see ADVERSE REACTIONS).
Susceptibility/Resistance
Development of Drug Resistant Bacteria: Prescribing Viaderm K.C. ® Cream and Viaderm K.C. ® Ointment in the absence of the authorized indications is unlikely to provide benefit to the patient and risks the development of resistant organisms.
Potential for Microbial Overgrowth: As with any antibiotic preparation, prolonged use may result in overgrowth of nonsusceptible organisms, including fungi other than candida. Constant observation of the patient is essential. Should superinfection due to non-susceptible organisms occur, Viaderm K.C.® Cream and Viaderm K.C.® Ointment should be discontinued and appropriate therapy instituted.
Skin
When steroid preparations are used for long periods in intertriginous areas or under occlusive dressings, striae may occur. Damage to collagen, which constitutes a middle layer of the tympanic membrane, may occur. Delayed healing and systemic effects, including adrenal suppression and subcapsular cataracts, may occur if absorbed in appreciable amounts.
If local irritation or sensitization develops, Viaderm K.C.® Cream and Viaderm K.C.® Ointment should be discontinued and appropriate therapy instituted. Prolonged use of corticosteroids may produce atrophy of the skin and subcutaneous tissues, particularly on flexor surfaces and on the face. If this is noted, discontinue the use of the product.
The use of occlusive dressings is not recommended with products containing anti-infective agents (see ADVERSE REACTIONS).
Special Populations
Pregnant Women: The safety of Topical Corticosteroid preparations during pregnancy and lactation has not been established. The potential benefit of the use of topical corticosteroids during pregnancy should be weighed against possible hazards to the fetus.
Nursing Women: It is not known whether Topical Corticosteroids are excreted in human milk. Topical Corticosteroids should not be used during breast feeding unless the potential benefit justifies the potential risk to the nursing infant.
ADVERSE REACTIONS
Adverse Drug Reaction Overview
The following adverse skin reactions have been reported with the use of topical corticosteroids: dryness, itching, burning, local irritation, skin atrophy, striae, atrophy of subcutaneous tissue, folliculitis, acneiform eruptions, hypertrichosis, change in skin pigmentation and telangiectasia. Adrenal suppression has also been reported following topical corticosteroid therapy. Posterior subcapsular cataracts have been observed following systemic corticosteroid therapy. Hypersensitivity reactions to neomycin, gramicidin, and nystatin have been reported. Systemic neomycin toxicity has occurred rarely following topical administration; tinnitus and deafness have also been reported. Overgrowth of non-susceptible organisms has occurred.
DOSAGE AND ADMINISTRATION
Recommended Dose and Dosage Adjustment
Viaderm K.C.® Cream: Each gram contains triamcinolone acetonide 1 mg, nystatin 100,000 units, neomycin base (as sulphate) 2.5 mg, and gramicidin 0.25 mg.
Viaderm K.C.® Ointment: Each gram contains triamcinolone acetonide 1 mg, nystatin 100,000 units, neomycin base (as sulphate) 2.5 mg, and gramicidin 0.25 mg.
Apply a small quantity two or three times daily. Do not apply more than prescribed by physician. For external use only.
OVERDOSAGE
For management of a suspected drug overdose, contact your regional Poison Control Centre.
Percutaneous absorption of corticosteroids can occur, especially if used over a large area for prolonged periods of time. If large amounts of corticosteroids are absorbed, toxic effects may include mild reversible suppression of adrenal function, ecchymoses of the skin, peptic ulceration, hypertension, aggravation of infections, hirsutism, acne, edema and muscle weakness due to protein depletion. Prolonged use of large amounts of Viaderm K.C.® Cream and Ointment would likely increase the absorption of neomycin which in turn would enhance the potential for nephrotoxicitiy and ototoxicity as well as ulceration.
No specific antidote is available, treatment should be primarily symptomatic and administration of the cream or ointment discontinued.
ACTION AND CLINICAL PHARMACOLOGY
Viaderm K.C.® Cream and Viaderm K.C.® Ointment (Triamcinolone Acetonide, Nystatin, Neomycin Sulfate and Gramicidin) provide relief from the itching and burning associated with secondarily infected inflammatory conditions by virtue of:
- the anti-inflammatory antipruritic and vasoconstrictive properties of triamcinolone acetonide;
- the broad spectrum anti-bacterial activity of neomycin and gramicidin;
- the anti-candidal activity of nystatin.
