Examination revealed hypertension (155/100 mmHg), tachycardia (95 beats per minute), abdominal pain and leucocytosis with neutrophilia, hyponatraemia and hypokalaemia. Urine was positive for nitrites, elevated bilirubin and cannabinoids. The patient was diagnosed with acute intermittent porphyria (AIP) and immediately treated. After initial treatment, the patient improved. However, he subsequently relapsed after initiating treatment with oseltamivir for a flu-like illness. Treatment was discontinued and the patient progressed favourably. AIP recurrence could have been mediated by oseltamivir; an association not previously described in the literature. %U https://www.rcpjournals.org/content/clinmedicine/22/3/280.full.pdf
