As of 13 August 2026, AI can only partly explain the side effects of your medicine.
This still needs a person who signs their name to it.

How to actually do it
- Open the patient information leaflet that came with the medicine, or find the official leaflet through the NHS or GOV.UK, and copy its side-effects section.
- Write down the medicine name, strength, dose, when you started it, why you take it, and when each symptom began.
- Add your other medicines, supplements, allergies and relevant health conditions, or write that any of these are unknown.
- Paste the copied leaflet text and the details into the prompt, then ask the chatbot to separate routine information from warning signs.
- Compare every claimed side effect with the leaflet and the relevant NHS information, removing anything the sources do not support.
- Take the checked list and your symptom timeline to a pharmacist or prescriber, and contact NHS 111 or 111.nhs.uk for urgent or worrying symptoms instead of relying on the chatbot.
Prompt
Explain the possible side effects of [medicine name and strength] using the patient information leaflet pasted below and current NHS information where available. I am taking it for [reason, if known], started it on [date or approximate time], and I have noticed [symptoms and when they started]. My other medicines, supplements, allergies and relevant conditions are [details or unknown]. Do not diagnose me, say that a symptom is definitely caused by the medicine, or tell me to start, stop or change a dose. Separate common effects from serious warning signs, quote or clearly label information that comes from the leaflet, and say what information is missing. Tell me which questions to ask a pharmacist or prescriber. If the symptoms could be urgent or worrying, tell me to contact NHS 111, use 111.nhs.uk, or call 999 where appropriate rather than relying on this chat.

What it gets wrong
- AI cannot examine you or measure your symptoms, so it cannot determine whether a reaction is mild, serious or unrelated.
- AI cannot reliably account for your complete medical history, allergies, interactions and prescribing context unless you provide accurate and complete information.
- AI cannot safely decide whether you should stop, restart or change a prescribed medicine.
- AI may confuse similar medicines, outdated information or a symptom that needs urgent treatment.
- A chatbot cannot take clinical responsibility for the consequences of acting on its explanation.

FAQ
- Can AI tell me if my medicine is causing my symptoms?
- It can compare your symptoms with listed side effects and help you prepare questions, but it cannot establish the cause. Check the leaflet and speak to a pharmacist or prescriber, and contact NHS 111 for urgent or worrying symptoms.
- Can AI explain the side effects of my medicine?
- Yes, it can summarise the leaflet and NHS information if you provide the exact medicine and strength. Treat the result as general information, not a diagnosis or a reason to change your medicine.
- Is it safe to use ChatGPT to check medicine side effects?
- It is suitable for organising general information and questions for a pharmacist, but it is not a safe substitute for clinical assessment. Do not use it to decide whether to stop or change a prescribed medicine, and use NHS 111 for urgent or worrying symptoms.
- When should I call NHS 111 for medicine side effects?
- Use NHS 111 or 111.nhs.uk when symptoms are urgent or worrying, or when you are unsure how quickly you need medical help. Call 999 for a life-threatening emergency, rather than waiting for an AI explanation.
