I have always wondered about the grapefruit juice warning with medications, but I have been to lazy to actually read why it's dangerous.
There's some kind of enzyme that increases the effect of a multitude of drugs, including blood pressure and cholesterol medications.
I first learned this when caring for my elderly grandmother, doling out her daily medications. She always liked to eat half a grapefruit with breakfast, and I told her to stop until we could clear it with her doctor.
For that particular medication at that dosage, and with my grandmother specifically, it was okay to eat half a grapefruit a day for her. It might not be the same for everyone.
That exact scenario played through my mind and made me shudder. It's one thing if you're drinking and taking it, you know you're getting fucked up big time. Someone eating a grapefruit is prime for a potential sneak attack. Scary thought
Hm, now that I think on it... I can't recall the last time I've received a medication from a doctor and been warned about anything listed on the bottle.
Dirty secret of the medical industry... so I was a pharmacy technician for a while. Most doctors don't know shit about the medications they are prescribing. They don't understand how it affects the body, long-term effects, interactions, etc..
In the USA, we call them "pharmacists", but most of the world knows them as "chemists". These are the people who studied the effects of chemicals on the human body. These are the people that often catch POTENTIALLY LETHAL mistakes made by doctors.
It would terrify you if I told you how many times I went to fill a prescription, saw the list of meds the patient was on, and immediately realized "Holy shit if this guy takes this he might die". Then I tell the pharmacist, he/she confirms this, calls the doctor and tells him/her they are a dumbass, and find an alternative. This is like 50% of the job of a pharmacist, fixing doctor's fuck-ups.
