If you're taking medicine you should be careful about what you drink and what drugs you take. This applies to all medicines including antibiotics, drugs for mental health problems and painkiillers.
Scientists and doctors have worked out some of the ways in which our bodies and minds react to different mixtures of medicines and drugs, but nowhere near all of them. This means that if you put a mixture into your body there's no way of knowing what might happen. It's safer not to if possible.
