After drinking milk, it is recommended that it is more appropriate to take the medicine after two hours. Milk tends to affect the absorption of drug components by the gastric mucosa, and can form a protective film on the gastric mucosa, causing calcium and magnesium ions in milk to free out and chemically react with some components of the drug, forming insoluble chemicals that can easily cause harm to the human body. Do not drink milk during the period of taking medication when you are sick, and do not drink milk within two hours before and after taking medication to avoid affecting human health. Milk is a high-protein, high-calcium, high-nutrient food that should not be consumed on an empty stomach to avoid damage to the gastrointestinal mucosa and affect digestive function. It is best to consume it together with other foods to facilitate the absorption of nutrients and benefit human health. Drinking a glass of milk at night before going to bed can promote sleep and improve insomnia symptoms.
