What an interaction is
Some medicines change how other medicines work, making them weaker, stronger or more likely to cause side effects. Foods, caffeine, energy drinks and alcohol can interact too.
Natural doesn't mean safe
Herbal, ayurvedic, homoeopathic and other traditional remedies, vitamins, protein powders and supplements can also interact with medicines. Some contain undeclared ingredients. Please don't start any of these alongside a prescribed medicine without asking.
Tell everyone everything
Each time you see a doctor, dentist or pharmacist, tell them everything you take, including from the chemist, online, or a traditional healer. A written list makes this easy.
When to talk to someone
Before starting anything new alongside a prescribed medicine, ask the pharmacist: 'Is it safe to take this with what I already take?'
