medicines all do very different things and all have their own side effects. i would hope your doctor is not sending you the message that they are arbitrarily interchangeable. he or she should be telling you the pros and cons of each (what specific benefits if any can be expected from each) as they pertain to your specific symptoms and problems. it's not the patient's job to tell the surgeon what kind of sutures the surgeon should use.
i am afraid of medication side effects so my doctor gave me a list of drugs to look up and choose from. is this ok?
