- thallous chloride, tl-201
- vasopressin
Interactions between your drugs
vasopressin thallous chloride Tl-201
Applies to: vasopressin, thallous chloride, tl-201
MONITOR: Coadministration of certain drugs may alter the myocardial uptake of thallous chloride Tl-201 and interfere with results of myocardial imaging studies. Drugs that increase or decrease coronary blood flow or potassium uptake may alter the biodistribution of thallous chloride Tl-201. Use of these drugs with thallous chloride TI-201 during imaging studies may result in a decrease in the number and size of perfusion defects, the appearance of false myocardial defects, and a decrease in myocardial localization and an increase in liver localization.
MANAGEMENT: Clinicians should be aware of possible diagnostic interference by these drugs.

Drug and food interactions
vasopressin food
Applies to: vasopressin
MONITOR: Alcohol may decrease the antidiuretic effect of vasopressin. Clinical studies found that plasma vasopressin levels often decrease during alcohol consumption and increase upon cessation of consumption. In addition, alcoholics were found to have a more pronounced decrease in plasma vasopressin levels when drinking and suppressed vasopressin levels even during alcohol withdrawal as compared to non-alcoholic individuals. The mechanism of this interaction is not fully understood.
MANAGEMENT: Patients should be advised to abstain from alcohol during vasopressin treatment. Hemodynamic monitoring is suggested for patients known to drink alcohol while receiving vasopressin.
