Be sure to get your doctors advice about any medication before you start. Always read the the instructions and check the label to ensure you are not allergic to any of the ingredients. Unwanted or unexpected symptoms or feelings that occur when you take medicine are called side effects. If you experience side effects, write them down so you can report them to your doctor accurately. Call your doctor right away if you have any problems with your medicines or if you are worried that the medicine might be doing more harm than good.
