Carbonate Beverages
Carbonated drinks, such as Coke, Sprite, mirinda, etc. The neutralization of carbon dioxide by gastric acid will increase the absorption of weakly alkaline drugs, which can indirectly lead to overdose and adverse reactions. Carbonated drinks will increase the gastrointestinal irritation of ibuprofen and other drugs, and also affect the stability of some drugs.

Tea Drinks
Traditional Chinese medicine and western medicine are not suitable for tea drinks. Tea contains more tannins, which can reduce the bioavailability of enzyme preparations and increase the antibacterial activity of antibiotics. Tannin can precipitate with iron and zinc preparations such as zinc sulfate, zinc gluconate, ferrous sulfate and iron fumarate, which not only hinders drug absorption, but also stimulates gastric mucosa, which may cause nausea, vomiting, diarrhea, abdominal pain and stomach discomfort. Tannin and alkaloids such as digitalis glycoside, ephedrine and quinine precipitate, denature and inactivate, which reduces its curative effect.
Tea contains 2%~4% caffeine and trace theophylline and theobromine, which has the functions of exciting higher nerve center, strengthening heart, diuresis and stimulating gastric acid secretion. Oral sedatives, sleeping pills, antihistamines, antitussive drugs, and traditional Chinese medicines such as Anemarrhena asphodeloides, Fritillaria, and Ziziphus jujuba seeds are also not suitable for drinking tea, because tea has antagonistic effects with these drugs, which reduces the curative effect.

Milk beverage
Milk and milk-containing beverages are rich in protein, which will obviously affect the absorption rate of drugs and reduce the efficacy. Taking medicine with milk-containing beverage is easy to cause calcification of gastrointestinal tract, which leads to ineffective drug efficacy, and even leads to gallstones and kidney calculi in severe cases. Rich calcium ions in milk-containing beverages can form complexes or chelates with tetracyclines and isoniazid, which are difficult to be absorbed by gastrointestinal tract and weaken its antibacterial effect. When digitalis, digoxin and other drugs are treated, calcium ions can also cause toxic reactions. In addition, milk, cheese and other dairy products are rich in histidine, which should not be taken with antiallergic drugs at the same time, so as to avoid histamine accumulation in the body and induce dizziness, headache, palpitation and other uncomfortable symptoms. In addition, you should not drink milk when taking antidiarrheal drugs, because milk not only reduces the efficacy of antidiarrheal drugs, but also contains lactose that may aggravate diarrhea. Therefore, it is best not to drink milk-containing drinks within 2 hours before and after taking the medicine.
