Summary
Heavy or acute alcohol intake impairs platelet function and can injure the gastric mucosa, and so may raise bleeding risk in patients on low-molecular-weight heparin. Intoxication also increases the risk of falls and trauma.
What this interaction means in plain words
Dalteparin and Ethanol can affect each other. The combination is often manageable, but it may need a change of dose, a change of timing, or extra checks while both are taken.
Why it happens
Additive pharmacodynamic effects of alcohol on platelet function and mucosal integrity; no direct effect on dalteparin kinetics is established.
What to do
Counsel patients to avoid binge or heavy alcohol use during dalteparin therapy. Monitor for bleeding, especially gastrointestinal, in patients who drink.
