Interactions with Dietary Supplements
Magnesium
One double-blind study showed that giving magnesium intravenously before surgery dramatically
reduced the amount of fentanyl needed to control pain during and after an
operation.1 Further research is needed to determine whether people using fentanyl
patches might benefit from supplementing with oral magnesium.
Interactions with Foods and Other Compounds
Alcohol
Drinking alcoholic beverages while using fentanyl patches increases the likelihood of side
effect, such as drowsiness, dizziness, and poor coordination.2 Therefore, people
using fentanyl patches should avoid drinking alcohol, especially when they must stay alert.
People who chronically consume alcohol require larger amounts of fentanyl to achieve adequate
levels of anaesthesia.3 Further research is needed to determine whether chronic
alcohol consumption increases the amount of fentanyl needed to relieve pain.
