i feel a lot of psychiatrists don’t mention this crucial piece of information, so here it is: if you’re on a psychiatric medication (or other prescriptions meds), chances are you should NOT be eating grapefruit. you should also be careful to not eat other citrus fruits in large quantities.
Grapefruit juice blocks special enzymes in the wall of the small intestine that actually destroys many medications and prevents their absorption into the body. Thus, smaller amounts of the drugs get into the body than are ingested. When the action of this enzyme is blocked, more of the drugs get into the body and the blood levels of these medications increase. This can lead to toxic side effects from the medications.
the medications vary, but include especially psychiatric medications, and those mentioned here:
The list of medications that can interact with grapefruit is long and includes commonly prescribed medicines that fight infections, reduce cholesterol, treat high blood pressure and treat heart problems.
some more information from the cbc:
David Bailey, a clinical pharmacologist at the Lawson Health Research Institute in London, Ont., discovered the interaction between grapefruit and certain medications more than 20 years ago. Since then, he said, the number of drugs with the potential to interact has jumped to more than 85.
Of the 85 known drugs that interact with grapefruit, 43 can have serious side-effects, including sudden death, acute kidney failure, respiratory failure, gastrointestinal bleeding and bone marrow suppression in people with weakened immune systems.
The authors noted that all sources of grapefruit — the whole fruit or 200 mL of grapefruit juice — and other citrus fruit such as Seville oranges (often used in marmalade), limes and pomelos can lead to drug interactions.
& lastly, nps has a non-complete list of medications that do interact with grapefruit, that link is here.
if you’re on medication, especially psychiatric medication, i highly recommend you google your specific drug to find out about grapefruit interactions, or phone your pharmacy and ask the pharmacists.
please feel free to reblog, unfortunately a lot of doctors don’t warn patients about the danger of grapefruit and i want people to be aware.
