Taking Medicines

Frequently Asked Questions

20. What are drug interactions?

Drug interactions occur when a medicine interacts chemically with another drug or with certain foods. These interactions change the way your body handles one or both substances, which can change the safety or effectiveness of either or both drugs.

Always inform your doctor or pharmacist about all medicines you are taking. Ask whether the medications might interact with any foods or other over-the-counter drugs or supplements you may also be taking.
