"Here’s a brief and incomplete list of some of the medications that research indicates get screwed up by grapefruit: Benzodiazepines (Xanax, Klonopin, and Valium) Amphetamines (Adderall and Ritalin) Anti-anxiety SSRIs (Zoloft and Paxil) Cholesterol-lowering statins (Lipitor and Crestor) Erectile-dysfunction drugs (Cialis and Viagra) Various over-the-counter meds (Tylenol, Allegra, and Prilosec) And about a hundred others." https://www.atlasobscura.com/articl...oDIP8ek9YWZ2NxoYQnMWzZ6ZIYKKQ11fBGhCDicKJM_8Q
All those drugs may seriously mess up the potential good from grapefruit , juice, and other healthy foods and juices.
or it may be advantageous should someone use it as an adjuvant to their rx. if it boosts the bioavailability (as vitamin c usually does) then one could adjust their dosage to accommodate and take less.
My friend was warned not to eat foods like kale and other vitamin K rich foods after being put on meds. I want to know why they just didn't tell him to eat the kale instead of the meds.
First response from medical authorities and doctors using/prescribing dangerous mind changing drugs like zanacks is NO, NO, and NO. They are strongly trained in the protocol of such drugs, and not at all in adjusting the dose to use it as if safely with grapefruit , juice, or other natural helps. Two people each on zanachs prescriptions had a lot of trouble with the drugs, as prescribed, even without trying more helpful avenues. The interaction is too strong to risk , and the drugs are too strong at any dose to keep taking , but require either a miracle to stop, or six months to a year to get off the drugs under a doctor's supervision . It did surprise me very much in the last couple years how bad the interaction of grapefruit was/is/ with the drugs, but it apparently changes the absorbtion rate or amount so much that very serious things occur or are likely while taking those dangerous drugs. It is next to impossible to get off those dangerous drugs without the prescribers help , both legally and medically , to protect one's health.
Those specifically I don't know, but often have seen those type of warnings in order to mainly protect the druglords profits. They claim vitamin c , or claimed, could interfere with chemo for treatment of someone with naughty cells misbehaving. Actually , vitamin c when taken can eliminate the side effects totally, sometimes, and other times or most of the time if someone is learning about and using natural approaches with someone with experience , knowledge and training the vitamins too often make the problem /disease/ go away, and kemo is not needed nor desired - i.e. the long time known preventions and cures eliminate the need for druglords products most of the time.
That's a little hard for me to believe because paramedics even learn about drug-drug, drug-food, drug-herb, and drug-vitamin interactions. Just because some doctors or pharmacologists may not take the proper precautions, that doesn't mean that it wasn't included in their training. A significant percentage of medical calls with senior patients that we saw, as paramedics, were due to drug interactions with other drugs or other substances, and if we didn't flag it ourselves, the ER doctors were pretty darned good at it. It's a few years old now, but one book that I used in teaching paramedic classes was The People's Guide to Deadly Drug-Drug, Drug-Food, Drug-Vitamin Combinations. A more recent publication (but not one that I am personally familiar with) is Meded101 Guide to Drug Food Interactions.
They do not try to adjust the dose in order to be able to take grapefruit. They simply say do not take grapefruit, and not nearly all the patients are told this - so the medical staff does know sometimes, yes, when a food /juice/ has caused a problem, but they do not - and probably are told not to - attempt to adjust the dose to allow taking grapefruit with the dangerous drugs. EVEN the GOOD doctors, who never prescribe the dangerous drugs, do not try to adjust the doses of the dangerous drugs to be able to consume the grapefruit, etc, except maybe possibly in rare cases - the liability is so strong and expensive. The GOOD doctors take up to a year or two or more if needed, to ween someone OFF the dangerous drugs BEFORE saying okay to the good foods and juices .
If Democrats are the enemy, Republicans are collaborators. Has anyone found a politician in any party or independent who is even just willing to shut down the drug makers and sellers in their own city, state , or country ? The money involved makes it pretty much impossible, and the whistle-blowers/ truth-tellers get squashed, silenced, and 'disappear' often, like the micro-biologists the last two years who proved the pandemic is fake and the measures taken all harmful to people.
Depending on the drug, and particularly the expense of it and the ability of the patient to pay, some doctors will indeed recommend lower doses of specific drugs to be taken with grapefruit juice because the therapeutic effects of some drugs are enhanced by grapefruit juice; therefore, a lower dose will suffice. They may not do that for people who are fully insured or who can afford their medication but when they fear that a patient will underdose due to an inability to afford the medication, some doctors do that. Before you criticize the expertise of people in the medical professions, it would be a good idea to know what they actually do learn and are capable of.
