The idea behind the low-carb diet is that decreasing carbs lower insulin levels, which causes the body to burn stored fat for energy and ultimately leads to weight loss. In general, a low-carb diet focuses on proteins, including meat, poultry, fish and eggs, and some nonstarchy vegetables.
Your doctor will tell you how long you need to take warfarin for, and when you should stop taking it. Some people will take warfarin long term, for as long as their blood-clotting risk continues. Other uses (such as after surgery) are usually short term.
The antidote for a warfarin overdose is vitamin K, which can be given in tablet or injectable form. These treatments must be done carefully. If too much vitamin K is given, this can reverse the effect of warfarin so much that it is no longer effective for preventing blood clots.
