If youâre using B vitamins to help prevent hot flashes, be sure to use the form of niacin called niacinamide. Other forms of niacin dilate the blood vessels, which can cause flushing and worsen hot flashes, rather than relieve them. Folic acid helps the body manufacture and use estrogen.
Soliris wins the prize as the most expensive drug in the United States. Unlike many of the drugs on this list, at least Soliris can claim to be a very effective drug, treating paroxysmal nocturnal hemoglobinuria, a disorder affecting about 8,000 Americans.
The most expensive drug in the U.S. is Soliris, from Alexion (ALXN). It costs $409,500 a year, and treats a rare disorder in which the immune system destroys red blood cells at night. Many of the most expensive drugs -- such as Soliris -- treat rare diseases that only a few hundred people suffer from. Those drugs aren't the real problem. Rather, it's the drugs in the $20,000 to $100,000 range, which mainly treat cancer and multiple sclerosis. Those diseases are very common in the elderly population.
