Yes. The furanocoumarins in grepefruit inhibit the CYP3A4 enzyme and some others to amplify the action of the drug so can mess with lots of drugs incl statins, blood thinners, gout, calcium blockers etc. Better to avoid.
Had my Abbott ILR implanted today. Easy procedure, now linked to my phone. Extremely boring Bluetooth app! Doesn’t show me anything but reports to the centre if an issue.
