Got to be so careful with drugs interacting but I never knew about the grapefruit thing for a long time. Always best to read the advice in the packages given and pharmacists should be a good point of call. I’ve had those question in the past drugs I’ve been prescribed, which is good. GPs don’t know everything understandably, many follow nhs guidance (blanket statin good example thereof) so need to ensure we don’t blindly accept drugs but do need to ensure we don’t rule stuff out for fear too. Statins May be needed for some people, But as I said, blanket prescription I don’t feel comfortable withI stand corrected. This is 2007 and I think things have now improved.
Here are examples of some types of drugs that grapefruit juice can cause problems with (interact): Some statin drugs to lower cholesterol, such as Zocor (simvastatin) and Lipitor (atorvastatin). Some drugs that treat high blood pressure, such as Procardia and Adalat CC (both nifedipine).1
Interestingly it seems it’s not just grapefruit but potentially other citrus fruits can also interact
