Which foods need to be taboo during medication?

It's your habit to finish the medicine and eat it. But all the drugs involved in the digestive process may interact with the cigarette you smoked, the juice you drank, and the food you eat. Therefore, it is necessary to understand what kind of taboos you are taking for the drug and prevent the drug efficacy from being compromised or even adverse reactions.

Smoke - any drug

Do not smoke for 30 minutes after taking any medication. Because nicotine accelerates the rate at which the liver degrades drugs.

Nicotine reduces blood concentration

Dr. Wei Minji of the Institute of Clinical Pharmacology at Peking University said that in recent years, a large number of medical workers have proved that smoking not only harms health but also interferes with drug metabolism, reduces drug efficacy, and even delays disease progression.

Nicotine contained in cigarettes will have an impact on the metabolic enzyme system in the liver after entering the human body, which will speed up or slow down the process of drug metabolism, resulting in a decrease in the effective concentration of the drug in the blood and failing to exert its due effect. Nicotine can release antidiuretic hormone, so that metabolites can not be discharged in time, leading to drug accumulation poisoning. In addition, smoking excessively depletes the minerals and essential nutrients needed to synthesize vitamin C, vitamin B6, and vitamin B12, which indirectly adversely affects the drug treatment process.

It is best to quit smoking during medication

Of course, not all medicines are obviously affected by smoking. Medical research shows that drugs that are significantly affected by smoking include antipyretic analgesics, drugs, antiasthmatic drugs, anti-angina pectoris drugs, antiplatelet drugs, lipid-lowering drugs, hypoglycemic drugs, diuretics, antacids, and gastric mucosal protection. Drugs, birth control pills, etc., common are theophylline, caffeine, propranolol, antipyrine, imipramine, phenacetin, analgesic new, propoxyphene, furosemide and so on.

Therefore, Dr. Wei suggested that special care should be taken when taking these drugs. First, it is best to quit smoking during medication, especially in patients with diabetes, cardiovascular disease, peptic ulcer, lung disease, allergic disease and cancer. Because smoking has the greatest impact on the incidence and efficacy of these diseases. Second, do not smoke within 30 minutes after taking the medicine. Experiments have confirmed that if the patient smokes within 30 minutes after taking the drug, the plasma concentration will be reduced to 1/20th of the time when he does not smoke, resulting in the failure of the drug to work properly.


Wine, Juice - Aspirin

Aspirin is a common antipyretic analgesic, and one of its main side effects is gastric mucosal injury. If you drink alcohol after taking aspirin, this side effect is often “magnified”. This is because: On the one hand, drinking itself can cause gastric mucosal damage, on the other hand, drinking can increase gastric acid secretion, increase aspirin on the gastric mucosal damage, light can cause gastric capillary hemorrhage, fecal occult blood positive, serious can Causes bleeding in the stomach. Therefore, when taking aspirin, it is necessary to “clear the boundaries” with alcohol. Patients with stomach ulcers and stomach hemorrhage should pay special attention.

In addition to aspirin, the wine is also a “family” of other antipyretic analgesics such as paracetamol, aminopyrine, and indomethacin. Wine not only reduces the efficacy of drugs such as paracetamol, but more seriously, it can cause severe liver and kidney damage, and even severe cases are life-threatening. This should be kept in mind for patients with hepatitis, cirrhosis, liver insufficiency, nephritis, and renal insufficiency.

Drinking fruit juice with aspirin will exacerbate the gastric mucosal irritation of aspirin and induce gastric bleeding.

Milk, Juice - Antibiotics

Do not drink milk or fruit juice within 2 hours before and after taking antibiotics. Because milk will reduce the antibiotic activity, so that the efficacy can not be fully exerted; and fruit acids (especially fresh fruit juice) rich in acid will accelerate the dissolution of antibiotics, not only reduce the efficacy, but also may generate harmful intermediates, increase toxic side effects.

Spinach - calcium tablets

Spinach contains large amounts of potassium oxalate, and the oxalate ions that are electrolyzed after entering the body will precipitate calcium ions, which not only prevents the body from absorbing calcium, but also easily generates calcium oxalate stones. Experts recommend that you do not eat spinach within 2 hours before or after taking calcium tablets, or boil the spinach first, and dissolve the potassium oxalate in water, then pour out the water before eating.

Cheese, meat products - anti-allergic drugs

Avoid eating foods rich in histidine such as cheese and meat during anti-allergic drugs. Because histidine in the human body will be converted to histamine, and anti-allergic drugs inhibit the decomposition of histamine, resulting in the accumulation of histamine in the body, induce dizziness, headache, palpitation and other symptoms.

Shrimp - Vitamin C

Do not eat shrimp within 2 hours before and after taking vitamin C. Because the rich copper in shrimp will oxidize vitamin C and make it ineffective; at the same time, the pentavalent arsenic component in shrimp will react with vitamin C to produce toxic “trivalent arsenic”.

Tea - Berberine

The tea water contains about 10% tannin. The tannin is decomposed into tannic acid in the human body. Tannic acid will precipitate alkaloids in berberine and greatly reduce its efficacy. Therefore, you cannot drink tea within 2 hours before and after taking berberine.

Milk - Antidiarrheal

Taking antidiarrheal medicine, you cannot drink milk. Because milk not only reduces the efficacy of antidiarrheal drugs, its lactose content also easily aggravates the symptoms of diarrhea.

Sweets - bitter stomach medicine

Bittersweet stomach medicine relies on bitterness to stimulate the secretion of saliva, gastric juice and other digestive juices, promoting appetite and aiding digestion. Sweet ingredients on the one hand mask the bitter taste, reduce the efficacy, and on the other hand also complex reactions with many ingredients in stomach medicine, reducing its active ingredient content.

Bananas, Oranges - Diuretics

During the diuretics, potassium is retained in the blood. If you eat more potassium-rich bananas, oranges, potassium accumulation in the body is more serious, easy to induce heart and blood pressure complications.

Coffee, Coke - Ibuprofen

Ibuprofen (Finbitron) is more irritating to the gastric mucosa. The caffeine contained in the coffee and the cocaine contained in the cola can stimulate the secretion of gastric acid, which will aggravate the toxic side effects of ibuprofen on the gastric mucosa and even induce Gastric bleeding, gastric perforation.

Grapefruit juice - antihypertensive drugs

Do not drink grapefruit juice while taking antihypertensive drugs. Because the naringenin component of grapefruit juice affects the function of an enzyme in the liver, and this enzyme is related to the metabolism of antihypertensive drugs, it will cause the drug concentration in the blood to be too high, and the side effects will be greatly increased.

Hot water - multiple enzyme tablets

Enzymes are active ingredients of multi-enzyme tablets and other digestive drugs. Enzymes, such as active enzymes, coagulate and denature in the presence of hot water, and lose their proper digestive action. Therefore, it is best to use low-temperature water when taking multiple enzyme tablets.

Radish - nourishing Chinese medicine

Nourishing Chinese medicines will nourish the yin and yang of the body's qi and blood through qi, and the radish will have a gas-breaking effect, which will greatly reduce the nourishing effect. Therefore, during the period of taking nourishing Chinese herbs, do not eat radish.
