From the Guidelines
The recommended treatment for oral candidiasis in a 4-month-old infant is nystatin oral suspension, with a typical dosage of 1 ml (100,000 units) applied to each side of the mouth four times daily after feeds for 7-14 days. This treatment is based on the evidence from the escmid guideline for the diagnosis and management of candida diseases 2012, which suggests that oral nystatin can reduce the burden of Candida in the gut and therefore the probability of translocation into the bloodstream 1. The guideline recommends oral nystatin, 1 mL 100 000 IU Q8 h, with a grading of B-II, indicating a reasonable amount of data to support its use in neonates 1.
When administering nystatin oral suspension, it is essential to apply the medication directly to the affected areas using a clean finger or cotton swab, ensuring it contacts all white patches. Treatment should continue for 48 hours after symptoms resolve to prevent recurrence. For breastfed infants, mothers should also apply nystatin cream to their nipples to prevent reinfection. If the infection is severe or doesn't respond to nystatin, fluconazole oral suspension at 3-6 mg/kg once daily for 7-14 days may be prescribed by a physician 1.
It is crucial to note that good hygiene practices, such as sterilizing bottles, pacifiers, and toys that go into the baby's mouth, can help prevent recurrence of oral candidiasis. If symptoms worsen or don't improve after a few days of treatment, parents should consult their pediatrician promptly. The use of miconazole oral gel is not recommended due to concerns regarding the generation of triazole resistance 1.
Key points to consider when treating oral candidiasis in a 4-month-old infant include:
- Using nystatin oral suspension as the first-line treatment
- Applying the medication directly to the affected areas
- Continuing treatment for 48 hours after symptoms resolve
- Practicing good hygiene to prevent recurrence
- Consulting a pediatrician if symptoms worsen or don't improve after a few days of treatment.
From the FDA Drug Label
Oropharyngeal candidiasis: The recommended dosage of fluconazole tablets for oropharyngeal candidiasis in children is 6 mg/kg on the first day, followed by 3 mg/kg once daily. Treatment should be administered for at least 2 weeks to decrease the likelihood of relapse Experience with fluconazole in neonates is limited to pharmacokinetic studies in premature newborns. Based on the prolonged half-life seen in premature newborns (gestational age 26 to 29 weeks), these children, in the first two weeks of life, should receive the same dosage (mg/kg) as in older children, but administered every 72 hours. After the first two weeks, these children should be dosed once daily.
For a 4-month-old infant with oral candidiasis, the recommended treatment is 6 mg/kg of fluconazole on the first day, followed by 3 mg/kg once daily. Since the infant is more than 2 weeks old, the dose should be administered once daily. The treatment should be continued for at least 2 weeks to decrease the likelihood of relapse 2.

Treatment Options for Oral Candidiasis in Infants
The treatment of oral candidiasis in infants, particularly those as young as 4 months, requires careful consideration of the available antifungal agents and their efficacy in this age group.
- Fluconazole: A study comparing fluconazole and nystatin oral suspensions for the treatment of oral candidiasis in infants found that fluconazole was superior to nystatin, with a clinical cure rate of 100% compared to 32% for nystatin 3.
- Nystatin: Although nystatin is commonly used for oral candidiasis, its efficacy in infants is lower compared to fluconazole. A systematic review and meta-analysis found that nystatin suspension was not superior to fluconazole in treating oral candidiasis in infants 4.
- Other Antifungal Agents: Other antifungal agents such as miconazole, itraconazole, and amphotericin B may also be effective in treating oral candidiasis, but their use in infants may be limited due to potential side effects or lack of data on their safety and efficacy in this age group 5, 6, 7.
Considerations for Treatment
When selecting a treatment for oral candidiasis in a 4-month-old infant, it is essential to consider the potential risks and benefits of each antifungal agent.
- Efficacy: The chosen treatment should be effective in eradicating the infection.
- Safety: The treatment should have a favorable safety profile, with minimal risk of adverse effects.
- Age and Weight: The treatment should be appropriate for the infant's age and weight, with careful consideration of the dosage and potential interactions with other medications.
Recommendations
Based on the available evidence, fluconazole appears to be a effective treatment option for oral candidiasis in infants, including those as young as 4 months 3, 7. However, the decision to use fluconazole or another antifungal agent should be made in consultation with a healthcare professional, taking into account the individual infant's needs and medical history.
