Side effects and interactions
Understanding side effects
All medicines have possible side effects, but not everybody will experience them. When you are recommended a medicine, it’s important to ask questions about side effects and what this means for you. Read more about where the information on side effects comes from and how to deal with problems.
Looking for your medicine’s side effects or interactions?
Use the medicine finder to find out about your medicine’s side effects and interactions, or ask your doctor or pharmacist.
Sometimes one medicine can mix badly with another in your body, and changes how strongly the medicine works or change its side effects. This is called an interaction, and it can also happen when medicines mix with certain foods or drink (including alcohol). Read more about interactions, when they are most likely to happen and what you can do to avoid them.
