You can’t drink lemon water with medicine: first of all, lemon water contains a lot of vitamin C. Vitamin C has an oxidizing effect, which can oxidize certain components of the drug, making the efficacy of the drug decrease, and in serious cases, there will be adverse side effects. Secondly, lemon water contains acidic substances, which can easily combine with the alkaline substances in the drug to affect the efficacy of the drug, or even lead to the deterioration of the drug, causing adverse side effects. Finally, if you are taking anti-inflammatory and analgesic drugs, drinking them with lemon water will increase their irritation. Because the drug itself has an irritating effect on the gastric mucosa, if lemon water is added to the drink will increase the irritation of the stomach wall, and in serious cases can lead to gastric perforation, gastric bleeding symptoms. Therefore, it is not recommended to drink lemon water together with drugs to avoid certain adverse symptoms and harm to the body.
