BACKGROUND
Sympathomimetic-related intracerebral hemorrhage is well-documented. Most cases are associated with phenylpropanolamine use.
METHODS
We report a case of intracerebral hemorrhage occurring in a middle-aged man who suffered from chronic sinusitis and had been ingesting pseudoephedrine daily
BACKGROUND
Dextran sodium sulfate (DSS) induces submucosal arteriolar constriction that reduces blood flow to the intestine, and the relevance of this decrease in flow needs further investigation. In the present study we examined the effects of a vasoconstrictor (pseudoephedrine) and a vasodilator
Intraventricular hemorrhage (IVH) occurred in a 32-year-old man following the use of both ephedrine and pseudoephedrine. Cerebral angiography and transcranial Doppler studies showed changes suggestive of vasculitis. We describe the management and investigations of a unique case of IVH. This patient
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 is a nasal vasoconstrictor and is contained in many cough and cold medications. It is generally harmless when used in recommended doses. Hypertensive crisis, psychosis, hemorrhagic stroke, and intracranial hemorrhage have been reported as severe complications. We report a 4-year-old
OBJECTIVE
To determine the efficacy and safety of decongestant prophylaxis among first-time underwater divers in the prevention of barotitis media (middle ear squeeze).
METHODS
Randomized, double-blind, prospective clinical trial.
METHODS

We report two cases of serious intracerebral haemorrhage occurring in young women following their first use of oral medications containing catecholaminergic agents (phenylpropanolamine in combination with ephedrine or pseudoephedrine). Both women were previously well, and there was no evidence for
Background: Primary intraventricular hemorrhage is an uncommon cause of stroke and is often associated with longstanding, uncontrolled hypertension. Reversible cerebral vasoconstriction is also an uncommon condition characterized by
Pseudoephedrine is contained in decongestants such as the Sudafed line of products. It is an alpha-adrenergic receptor agonist, which causes blood vessel constriction, including the therapeutic effect of reducing airflow resistance in the nasal cavity. Pseudoephedrine is one of the most commonly
OBJECTIVE
Phenylpropanolamine (PPA) and pseudoephedrine are sympathomimetics contained in over-the-counter cold preparations. A case-control study linked PPA use with hemorrhagic stroke in women. Twenty-two patients with stroke associated with use of these drugs are described.
METHODS
In a
Over-the-counter stimulants (phenylpropanolamine hydrochloride, ephedrine, pseudoephedrine, caffeine) are used widely as decongestants, anorectic agents, amphetamine substitutes, and "legal stimulants." Toxic effects may result from overdose, drug interactions, or diseases that increase sensitivity
BACKGROUND
The use of ephedra alkaloids in over-the-counter preparations has been associated with potentially serious cerebrovascular events. Because of its potential association with hemorrhagic strokes, phenylpropanolamine has been largely substituted for by pseudoephedrine, but it is not clear
Ephedrine is a long-studied stimulant available both as a prescription and over-the-counter medication, as well as an ingredient in widely marketed herbal preparations, and is also used as a precursor for the illicit synthesis of methamphetamine. Ephedrine is related to phenylpropanolamine, a
