Often, people discover medications prescribed by their doctor, or more likely doctors, have contraindications. They visit one physician and then, upon recommendations from a friend, visit a totally different one.
Neither doctor is aware of the other and each may prescribe meds separately…a dangerous combination! But, what is a contraindication? My grandfather would have referred to it as one of those big, 50 cent words. It simply means meds in conflict with other meds. Some are harmless but some put you 6 feet under.
