Medicines being an integral part of human life today have been under extensive study. We know drugs might interact with each other but do you know that a particular drug might also be affected by the diet you are taking?

Drug-food Interactions:

A drug-food interaction occurs when your food and medicine interfere with one another’s usual function. This may cause a change in a body’s ability to process a specific food or drug, or result in a serious side-effect. These interactions may happen due to accidental misuse or because of insufficient knowledge about the active ingredients of both food and medicine.

Always take medicines as prescribed by your doctor. If you are having difficulty finding a good doctor log on to and book an appointment with the best general physician in Karachi, Lahore or any other main city of Pakistan. You may inquire about additional information regarding medicines from a pharmacist.
