Have a patient with tinea capitis (ringworm of the scalp)? This is caused by a fungi that has invaded the scalp tissue.
Topical agents are ineffective because they do not penetrate sufficiently into the hair shaft.
Patients who present with Tinea Capitis should be given oral anti-fungals. My go to is either terbinafine or griseofulvin.
Both medication courses need to last for 4-6 weeks.
Also ensure that patients take these medications with food that are high in fat concentration, it will help aid in better drug absorption!
