A&D Ointment is NOT Appropriate First-Line Treatment for Perianal Candidiasis
A&D ointment should not be used as first-line treatment for perianal candidiasis in patients with fecal incontinence—topical azole antifungals (clotrimazole or miconazole) applied 2-3 times daily are the evidence-based first-line therapy. 1
Why A&D Ointment is Inadequate
A&D ointment is a petroleum-based barrier product containing vitamins A and D, but it lacks antifungal properties. While barrier ointments play a supportive role in managing incontinence-associated dermatitis, they do not treat the underlying fungal infection. 1, 2
- Candida requires antifungal therapy: Perianal candidiasis is caused by Candida albicans overgrowth, which necessitates specific antifungal treatment rather than simple moisture barriers. 3, 4
- Barrier creams alone are insufficient: While moisture control is critical for managing candidal skin infections, barrier products without antifungal activity will not eradicate the infection. 1
Correct First-Line Treatment Algorithm
Step 1: Confirm Clinical Diagnosis
Look for these classic signs of perianal candidiasis:
- Beefy-red erythema with white plaques
- Satellite lesions (small pustules or papules surrounding the main area)
- Maceration of perianal skin 1
Step 2: Initiate Topical Antifungal Therapy
- Apply topical azole antifungals (clotrimazole or miconazole cream) to the affected perianal area 2-3 times daily. 1, 2
- Alternative option: Nystatin cream can be used if azoles are unavailable or not tolerated. 1, 2
- Treatment duration: Continue for a minimum of 14 days and at least 2-4 weeks after clinical resolution to prevent recurrence. 2
Step 3: Critical Adjunctive Measures
- Keep the perianal area dry: Moisture control is essential for treatment success—change incontinence products frequently and allow air exposure when possible. 1
- Gentle cleansing: Use mild, pH-balanced cleansers rather than harsh soaps. 5
- Barrier protection after antifungal application: Once the antifungal cream has been absorbed, a barrier ointment (like A&D) may be applied over it to protect against ongoing fecal exposure—but this is adjunctive, not primary treatment. 6, 5
When to Escalate to Systemic Therapy
Consider oral fluconazole (100-200 mg daily for 7-14 days) if:
- No clinical response after 7-10 days of adequate topical therapy 1
- Extensive involvement beyond the perianal region to inguinal folds or buttocks 1
- Immunocompromised status with severe perianal candidiasis 1
Common Pitfalls to Avoid
- Do not use systemic antifungals as first-line for uncomplicated perianal candidiasis—topical agents are highly effective and avoid unnecessary systemic exposure. 1
- Do not confuse with pressure ulcers: IAD presents with color changes, superficial erosions, and lacks the depth and necrotic tissue seen in pressure ulcers. 5
- Do not rely solely on barrier products: Incontinent patients have increased Candida colonization rates (43% perianal colonization versus 28% in continent patients), requiring active antifungal treatment, not just barriers. 4
The Role of Barrier Products
Barrier creams like A&D ointment serve as adjunctive therapy to protect skin from ongoing fecal exposure during treatment, but they must be combined with antifungal therapy to address the infection itself. 6, 5 Think of barrier products as protective shields that prevent further damage while antifungals eliminate the pathogen—neither works optimally without the other in this clinical scenario.
