From the Guidelines
A ringworm treatment plan typically takes 4-8 weeks to cure the infection, but it may take up to 12 weeks in some cases 1. It's essential to complete the full treatment course, even if symptoms improve before finishing the medication.
Treatment Duration
The treatment duration may vary depending on the individual's condition, age, and the affected area. For example, the treatment duration for griseofulvin is typically 6-8 weeks 1, while terbinafine may require a shorter course of treatment, typically 2-4 weeks 1.
Medication Dosage
The medication dosage may also vary depending on the individual's condition and age. For instance, the recommended dose of griseofulvin is 15-20 mg/kg per day for individuals weighing less than 50 kg, and 1 g per day for individuals weighing more than 50 kg 1.
Importance of Completing Treatment
It's crucial to consult a healthcare professional for a proper diagnosis and personalized treatment plan. Completing the full treatment course is essential to ensure that the infection is fully cured, and to prevent recurrence.
Additional Measures
In addition to medication, it's essential to practice good hygiene, such as keeping the affected area clean and dry, and avoiding sharing personal items like towels and clothing. In some cases, additional measures like screening and treating family members and close contacts may be necessary, especially if the infection is caused by T. tonsurans 1.

From the Research
Treatment Duration for Dermatophytosis (Ringworm)
The typical duration of a treatment plan for dermatophytosis (ringworm) can vary depending on the specific treatment and the causative organism.
- For oral antifungal drugs such as fluconazole, griseofulvin, itraconazole, and terbinafine, treatment duration can range from 8 to 12 weeks 3.
- A study on the use of 2% ketoconazole shampoo as monotherapy for the treatment of tinea capitis found that daily treatment for 8 weeks resulted in clinical healing in 93% of patients 4.
- Once-weekly oral doses of fluconazole 150 mg have been shown to be effective in the treatment of tinea corporis/cruris and cutaneous candidiasis, with a mean of 2.6 doses administered 5.
- In children, once-weekly fluconazole has been found to be effective in the treatment of tinea capitis, with treatment durations ranging from 8 to 16 weeks 6.
- A comparative study of griseofulvin and terbinafine for the treatment of paediatric tinea capitis found that 12 weeks of griseofulvin treatment had a statistically significant better cure rate than 4 weeks of terbinafine 7.
Factors Affecting Treatment Duration
The duration of treatment for dermatophytosis can be influenced by various factors, including:
