Hi @ralphcramden, I emphatically underline what @pacathy said and strongly recommend that you do NOT nebulize with peroxide and iodine. These products are not to be used internally and nebulizing will not reach the infected area. Rather that could cause irreversible damage to her lungs.

Ralph, I see that you are very concerned for you mom and cannot imagine that she has to take penicillin for the rest of her life, which causes other disagreeable side effects. I understand.

I moved your question to the Digestive Health and the Heart & Blood Health support groups in case any one else has experienced such an infection.

Has she talked with a GI specialist? Might a second opinion be possible?
