Milk cannot be consumed because it is rich in milk protein. This substance can form a film layer in the surface mucosa of the stomach, intestines and other digestive organs, which directly affects the decomposition and absorption of drugs in the digestive tract, thus adversely affecting the effect of drugs. Milk contains a large amount of calcium, which can have mixed reactions with some of the components of the drugs, easily causing the occurrence of adverse symptoms in patients, such as dizziness, nausea, vomiting, and weakness of the limbs. Patients should avoid taking the drug with the following beverages such as grapefruit juice, alcohol, coffee, etc. during the drug intake. Because the above drinks contain ingredients that will not only cause irritation and impact on the gastrointestinal mucosa, but may even cause fainting, shock, death and other serious consequences. The correct way to take the medication should be served with warm water, so as to better ensure the effectiveness of drug treatment.
