title: Follow-up study of pseudoephedrine users.
abstract: A follow-up study of over 100,000 persons below age 65 years who filled a total of 243,286 prescriptions for pseudoephedrine indicated that there were no hospitalizations among users that could be attributed to the drug. There were no admissions within 15 days of filling a prescription for pseudoephedrine for cerebral hemorrhage, thrombotic stroke, or hypertensive crisis. There were a small number of hospitalizations for myocardial infarction, seizures and neuropsychiatric disorders, but the rate of such admissions among the pseudoephedrine users was close to the expected rate in the population at large.
