I have been concerned about the possibility of grapefruit interacting with the medication I am currently taking: letrozole, zoladex and zometa. I had my flu jab at my local pharmacy this afternoon, so I asked the pharmacist, and he didn't know. He even looked it up and could not find anything about it. He suggested I ask my oncologist or oncology nurses, so I did. I called, and again, she did not know. So she told me she would ask the hospital pharmacist. The pharmacist called me back and said that it is safe to eat grapefruit. Now I am waiting to hear back to find out if it's safe to eat soya products, as the oncology nurse forgot to mention that to the pharmacist. My concern is introducing plant oestrogens into my body, as I am oestrogen receptor-positive.
I just thought this might be of interest to others in the same boat as me.
