Drugs are involved in all stages of digestion and may interact with the cigarette you smoke, the juice you drink, or the food you eat. Before and after taking medication, be sure to temporarily avoid foods and drinks that are "incompatible" or "clash." When dietary restrictions are necessary, you must adhere to them to prevent reduced drug efficacy or adverse reactions, and in some cases, even turn the drug into a poison.
Any drug and smoking
You should not smoke within 30 minutes after taking any medication. Nicotine accelerates the liver's breakdown of drugs, leading to insufficient drug concentration in the blood and making it difficult for the drug to be fully effective. Experiments have confirmed that smoking within 30 minutes after taking medication can reduce the blood drug concentration to about 1/20 of that in non-smokers.
Aspirin and alcohol
After entering the human body, alcohol, including alcoholic fruit juices, needs to be oxidized into acetaldehyde and then further oxidized into acetic acid. Aspirin interferes with the oxidation of acetaldehyde into acetic acid, causing acetaldehyde to accumulate in the body. This not only aggravates symptoms like fever and body aches but can also easily lead to liver damage. Fruit juice, on the other hand, can intensify aspirin's irritation to the gastric mucosa, triggering stomach bleeding.
Berberine and tea
Tea water contains about 10% tannins. Tannins break down into tannic acid in the human body, which will precipitate the alkaloids in berberine, significantly reducing its efficacy. Therefore, you should not drink tea within 2 hours before or after taking berberine.
Ibuprofen and coffee/cola
The painkiller ibuprofen (also known as Fenbid) is highly irritating to the gastric mucosa. The caffeine in coffee and the cocaine in cola both stimulate gastric acid secretion, which exacerbates the toxic side effects of ibuprofen on the gastric mucosa and can even induce stomach bleeding or perforation.
Antibiotics and milk/fruit juice
Do not drink milk or fruit juice within 2 hours before or after taking antibiotics. Milk can reduce the activity of antibiotics, preventing them from being fully effective. Meanwhile, the fruit acids (especially in fresh juice) rich in fruit juice can accelerate the dissolution of antibiotics, not only reducing their efficacy but also possibly generating harmful byproducts and increasing side effects.
Calcium tablets and spinach
Spinach contains a large amount of potassium oxalate. After entering the human body, the oxalate ions released will precipitate calcium ions, which not only hinders the body's absorption of calcium but also easily forms calcium oxalate stones. It is recommended not to eat spinach within 2 hours before or after taking calcium tablets, or to first boil the spinach, dissolve the potassium oxalate into the water, discard the water, and then eat it.
Antiallergic drugs and cheese/meat products
While taking antiallergic drugs, avoid foods rich in histamine, such as cheese and meat products. This is because histamine is converted into histamine in the body, and antiallergic drugs inhibit the breakdown of histamine, leading to an accumulation of histamine in the body and inducing symptoms like dizziness, headache, and palpitations.
Anti-diarrheal drugs and milk
When taking anti-diarrheal drugs, you cannot drink milk. Not only does milk reduce the efficacy of the anti-diarrheal drug, but its lactose content can also easily worsen diarrhea symptoms.
Bitter stomachics and sweets
Bitter stomachics rely on their bitter taste to stimulate the secretion of digestive fluids like saliva and gastric juice to promote appetite and aid digestion. Sweet components, on one hand, mask the bitterness and reduce the drug's efficacy, and on the other hand, they can form complexes with many components in the stomachic, reducing the content of their active ingredients.
Diuretics and bananas/oranges
While taking potassium-sparing diuretics, potassium can be retained in the blood. If you also eat potassium-rich bananas and oranges at the same time, the accumulation of potassium in the body becomes more severe, which can easily induce complications related to the heart and blood pressure.
Vitamin C and shrimp
You cannot eat shrimp within 2 hours before or after taking Vitamin C. This is because the abundant copper in shrimp will oxidize Vitamin C, rendering it ineffective. At the same time, the pentavalent arsenic in shrimp can also react with Vitamin C to form toxic trivalent arsenic.
Tonic Chinese medicine and radish
Tonic Chinese medicines work by replenishing Qi, which in turn nourishes the body's Qi, blood, Yin, and Yang. Radish, however, has the effect of breaking Qi, which will significantly weaken the tonic effect. Therefore, radish should be avoided while taking tonic Chinese medicines.
Blood pressure medication and grapefruit juice
You cannot drink grapefruit juice while taking blood pressure medication. This is because the grapefruit components in grapefruit juice can affect the function of a certain enzyme in the liver, and this enzyme is related to the metabolism of blood pressure medication. This will cause the drug concentration in the blood to become too high, greatly increasing side effects.
Multi-enzyme tablets and hot water
Enzymes are the active ingredients in digestive aids like multi-enzyme tablets. This active protein denatures and coagulates when exposed to hot water, losing its proper digestive function. Therefore, it is best to take multi-enzyme tablets with cold water.
