The normal range for a healthy person not using warfarin is 0.8–1.2, and for people on warfarin therapy an INR of 2.0–3.0 is usually targeted, although the target INR may be higher in particular situations, such as for those with a mechanical heart valve. If the INR is outside the target range, a high INR indicates a higher risk of bleeding ...
Many studies showed a relation between the two; however, they were limited to short-term alcohol ingestion. The first human study to assess the long-term effects of alcohol ingestion on cortisol was conducted in 1966 (Mendelson et al.). They found heightened cortisol levels in both alcoholics and non-alcoholics while actively drinking.
Interestingly, in patients that are defined as "heavy drinkers" (defined as consuming >30g of alcohol/day) decreased alcohol consumption to moderate levels has been shown to be an effective treatment; in fact [12] A retrospective cohort study analyzed data collected from over 3.8 million patients, and categorized patients as either abstinent ...
Enzymes. Women have lower levels of two enzymes—alcohol dehydrogenase and aldehyde dehydrogenase—that metabolize (break down) alcohol in the stomach and liver. As a result, women absorb more alcohol into their bloodstreams than men. Hormones. Changes in hormone levels during the menstrual cycle may also affect how a woman metabolizes alcohol.
Excessive use of alcohol is known to affect the metabolism of warfarin and can elevate the INR, and thus increase the risk of bleeding. [100] The U.S. Food and Drug Administration (FDA) product insert on warfarin states that alcohol should be avoided. [101]

III. For people who consumed 6 or more drinks per day, reduction rate on blood pressure was the strongest when they reduced alcohol consumption close to abstinence. IV. The effect of alcohol reduction on blood pressure is still unclear for women and hypertensive patients who consume less than three drinks per day due to limited clinical trials.
Alcohol tolerance is increased by regular drinking. [1] This reduced sensitivity to the physical effects of alcohol consumption requires that higher quantities of alcohol be consumed in order to achieve the same effects as before tolerance was established. Alcohol tolerance may lead to (or be a sign of) alcohol dependence. [1]
