Drugs should not be taken immediately after drinking milk, but at least 1-2 hours apart. Milk is rich in protein, which can easily combine with drugs, thus affecting the absorption of nutrients and drugs in milk. Milk can affect the absorption and decomposition of certain drugs, and if both are taken at the same time, some substances in milk will react chemically with the drugs, thus reducing their effectiveness, and in serious cases, abdominal pain and diarrhea may occur. Therefore, at least 1-2 hours should be allowed between milk consumption and medication intake to avoid adverse consequences. Patients are advised to drink milk at least half an hour after taking medications, especially multivitamins, otherwise the milk will affect the reduction of vitamins, while the vitamins may deteriorate the milk and affect digestion and absorption. During taking medications, patients should also pay attention to avoid foods such as mung bean porridge and fish soup.
