More than anything I fear the antibiotics. I nearly died from taking a drug I had taken in the past. There are other drugs that are not deadly to me, but they seem to have an excessive effect. I am a small elderly woman and yet I am given a dosage for a large man. If I can convince a physician to prescribe a half sized dose I do better. I have a policy of not taking drugs that make me feel worse than I did before. Some of my family members have trouble with dosage as well. The doctor is either not tuned into my fear or he thinks he can handle whatever comes. He has been my gynecologist for a number of years and I trust his skills except in this area. How often are antibiotics needed? I have worked in a hospital and seen healthy people come in for a simple procedure only to develop sepsis and have the worst results. I have read on this procedure which is why I am deeply concerned about a negative result.
