It depends how you define safe. Different drugs affect different people in different ways. Just as one person can eat peanuts without risk, they can prove fatal to another. Many medical treatments have unwanted side effects and sometimes these side effects are not discovered, identified or acted upon for many years. It is really down to your medical professionals and yourself to judge the risk and the potential benefit. Cancer treatments, for example, can make you sick and cause your hair to fall out, but they can cure cancer so the potential benefits often outweigh the costs.
“Attention-deficit drugs increase concentration in the short term, which is why they work so well for college students cramming for exams. But when given to children over long periods of time, they neither improve school achievement nor reduce behavior problems. The drugs can also have serious side effects... Many parents who take their children off the drugs find that behavior worsens, which most likely confirms their belief that the drugs work. But the behavior worsens because the children's bodies have become adapted [because the drugs are habit-forming] to the drug. Adults may have similar reactions if they suddenly cut back on coffee, or stop smoking.”
“Depression and anxiety sort of run in my family but I always said I didn't have that affliction. Eventually my grandmother told me she could tell from some of the things I said that I did have some degree of depression. I wasn't convinced. Then I started taking Flavay and Flavay Plus and I felt a new positive psychological outlook. Sometimes I would take 2 capsules of each and sometimes 4 capsules of each since I had read online that some people like taking 4 of each better. When I ran out of Flavay and Flavay Plus I didn't reorder because I was feeling so good.
