  "abstract": "A man in his 40s presented to the dermatology clinic with a pedal rash and the patient was diagnosed as having tinea pedis. He was prescribed oral terbinafine (250 mg once daily), aiming for a course of up to three months. Three days after starting terbinafine, he described generalised muscle weakness, weak grip strength, and difficulty standing from sitting. He did not describe any preceding intense exercise or dehydration. On urgent review in clinic, he had 5/5 power in his upper and lower limbs, bar 4/5 grip strength bilaterally. A urinalysis was not performed because it was not available at the clinic. Table 1 presents the blood test results, which showed increased creatine kinase levels and normal results for liver function tests.",
