We do not suppose it, but the grapefruit is the champion of the contraindication.
Grapefruit and cholesterol medications don’t mix
The consumption of grapefruit is strongly discouraged with many drugs because this citrus fruit contains substances which increase the absorption of certain molecules by the intestine leading to an overdose. The risks are great enough that the grapefruit juice, widely consumed at breakfast, has been the subject of specific warnings from the American and French drug authorities.
Take special care if you are taking any treatment to soothe irritation of the esophagus (cisapride), from immunosuppressants (tacrolimus, ciclosporin) or cholesterol-lowering drugs (simvastatin, atorvastatin). In combination with taking cisapride, grapefruit can cause a sharp increase in heart rate.
As to cholesterol-lowering drugs, their concentration in the blood can be multiplied by fifteen by the grapefruit and attack the muscles. This increased risk of liver and muscle damage can lead to kidney failure.
Like other citrus fruits, grapefruit reduces the effectiveness of aspirin.
Dairy products: not with antidepressants or antibiotics
If you are addicted to camembert and you take antidepressants or an antibiotic (such as linezolid), you may need to choose.
Fermented cheeses are in fact not recommended with the intake of antidepressants containing iproniazid. These cheeses contain a chemical compound, tyramine (which is also found in high concentrations in sauerkraut, soy sauce and even beer and red wine) which, when combined with these drugs, can cause hypertension attacks.
As for milk, it reduces the action of certain antibiotics (tetracycline, ciprofloxacin). It is suspected, in addition, of limiting the effectiveness of aspirin by promoting its elimination.
Vegetables and blood thinners: the mixture to avoid
Broccoli, cabbage, spinach, lettuce, avocado do not go well with oral anticoagulant treatments. Wealth in vitamin K (the coagulation vitamin) of these plants reduces the effectiveness of these drugs, to the point of being able to promote clots. Do not consume more than one serving per day of any of these vegetables if you are on treatment.
As togreen tea, it’s the opposite. True natural anticoagulant, its action reinforces that of anticoagulant drugs and is likely to trigger bleeding.
Finally, the broccoli, moreover so beneficial to health, greatly limits the effectiveness of paracetamol.
Caffeine and drugs: the wrong combination
Whether it comes from coffee, tea (theine) or cola drinks, caffeine increases the absorption of paracetamol, the overdose of which can cause hepatitis.
Caffeine consumption should also be avoided if you are taking certain antibiotics containing enoxacin, ciprofloxacin or norfloxacin.
In addition, if caffeine increases the effect of certain molecules, it reduces the effectiveness of treatments against osteoporosis.
Finally, it also goes very poorly with asthma medications that contain theophylline. Sweating, palpitations can appear if you combine the two.
