Vasoconstriction

Definition

Vasoconstriction is the narrowing (constriction) of blood vessels. When blood vessels constrict, the flow of blood is restricted or slowed.

Vasoconstriction may be slight or severe. It may result from disease, medication, or psychological conditions. Medications that cause vasoconstriction include:

• Antihistamines and decongestants
• Cough and cold combinations
• Pseudoephedrine
• Caffeine

Medications may be used to treat vasoconstriction.
