| Abstract: | □ A systematic questionnaire was found to be a feasible method of facilitating patients to report symptoms they perceived to be potential adverse effects of drugs □ Although 89 per cent of patients who had taken tramadol and venlafaxine reported at least one symptom in questionnaires, only 58 per cent of these claimed to have reported their symptoms to their doctor □ Only 22 per cent of symptoms reported by a sample of patients were found to be recorded in medical records and only 23 yellow card reports were submitted to the CSM for the same period □ Low reporting rates to GPs and low recording rates would appear to be contributory factors to low rates of reporting to the CSM. |
