You should not drink cola while taking medicine. Cola is a common drink in life, which contains a large amount of carbonic acid. Drinking cola while taking medicine will cause the carbonic acid in cola to dissolve the outer film of the medicine. Some medicines contain caffeine and acetaminophen, and the reaction of these two ingredients with the carbonic acid in cola will increase the toxicity of the medicine, which will not only prevent the medicine from working, but also have a negative impact on human health. When taking medicine, in addition to not drinking with cola, you should not drink with milk or strong tea, otherwise it will affect the effect of the medicine. It is best to take it with warm water, which will not affect the ingredients in the drug and will not cause irritation to the stomach mucosa. It is also necessary to drink a lot of water after taking the medicine to promote the body’s metabolism and reduce the damage caused by the drug to the digestive system.
