(2) Systemic Treatment:
Systemic treatment is often required so as to cure tinea capitis within the shortest time possible. The drug most commonly used in this category is Griseofulvin. Physicians recommend doses of 10-20 mg/kg.
Just like with topical treatments, Griseofulvin should be used for a minimum of 8 weeks, though your physician may dictate otherwise depending on severity of your infection. There are two main reasons why Griseofulvin is the most preferred systemic drug:
- It’s the only licensed drug, besides being easily available in most dermatological clinics
- It can be converted into a syrup, perfect for children
However, Griseofulvin is gradually being replaced by more recent, safer options because of the following reasons:
- It must be taken for relatively longer time periods compared to more recent options
- The drug is not appropriate for pregnant women
- It has its own side effects that can cause additional stress and social disruption among users
The other systematic treatments that have been introduced include:
- Terbafine – Besides being associated with less severe side effects, terbafine only needs to be applied for up to 4 weeks. These factors have elevated it above griseofulvin in terms of effectiveness. The recommended dosage is 5 mg/kg of body weight.
- Fluconazole – It is given in the dosage of 6 mg/kg body weight and treatment takes just 4 weeks
Among all the drugs we’ve looked at, Griseofulvin remains the only licensed drug.
