Take the prescription and over-the-counter medicines, vitamins, and/or additional supplements as your doctor prescribes. Do NOT stop taking a prescription medication without first discussing it with your doctor. If you disagree with your doctor about some course of treatment, ask him/her to explain the reasons for the treatment.
You are perfectly entitled to seek another opinion from a second doctor or, if, you are really dissatisfied, you can find another doctor. Some women have difficulty finding a doctor they feel comfortable with and who will listen to them. If you are unhappy with your medical care, shop around. Don't ever settle for second best!
