There is little. To no clinical information on this topic. As far as the DVT itself is concerned, I doubt there's any help or harm. The issue would be problems with medication. Alcohol should be avoided when on Heparin. Patients on warfarin can probably have a couple of drinks a day with no problem. There is no evidence that alcohol affects treatment with factor/thrombin inhibitors (Xarelto, Pradaxa, etc).
Dvt. No data to support that however small amounts may be of benefit to prevent coronary and pad.
No. Alcohol can interfere with other medications for the DVT. Please avoid for now.
