AbstractThere is limited information on potentially adverse lisinopril ingestions reported to poison control centers. Using adult lisinopril ingestions reported to Texas poison control centers during 1998-2005, the proportion of cases involving serious outcomes was determined for selected variables and evaluated for statistical significance by calculating the rate ratio (RR) and 95% confidence interval (CI). Of 468 cases identified, 43 (9%) involved serious outcomes. The severity of the outcome associated with adult lisinopril ingestions depended on the dose and the circumstances of the ingestion. Thus, serious outcomes were significantly more likely to occur with a maximum dose >80 mg (RR 5.69, CI 2.43-13.33) or, if the dose was unknown, > or =3 tablets (RR 9.57, CI 2.39-54.97), where the circumstances of the exposures involved self-harm or malicious intent (RR 6.96, CI 3.65-13.31), or the patient was already at or en route to a health care facility when the poison control center was contacted (RR 7.33, CI 3.09-17.85) or referred to a health care facility by the poison control center (RR 23.76, CI 10.62-55.67). The management of patients with severe outcomes was more likely to involve health care facilities. Such information is useful for creating of triage guidelines for the management of adult lisinopril ingestions.
