Patients hospitalised for a severe headache or migraine can be treated safely and effectively with intravenous aspirin, US researchers have found.
They examined the records of 168 patients admitted and treated for severe headache with aspirin intravenously. Patients were given 1g doses of aspirin, receiving on average five doses.
More than 25 per cent of the time patients reported a significant reduction in pain, and 40 per cent of the time they reported a moderate effect. Six per cent of patients experienced side effects, none of which were severe.
