Ask about symptoms, medicines, or conditions. Prescriba gives you clear, structured guidance — and always tells you when to see a professional.
Medical disclaimer: Prescriba provides general health information only. It does not diagnose conditions or replace your doctor. Always consult a qualified healthcare professional for personal medical decisions. In an emergency, call 999 immediately.
Evidence-based guidance for everyday health questions — always safe, always clear.
Describe what you're feeling in plain language. Get structured, cautious information about possible causes and what to monitor.
Dosage, side effects, interactions, pregnancy safety, missed dose guidance — for hundreds of medications.
Red-flag symptoms trigger immediate urgent guidance and direct you to emergency care before anything else.
Every response draws from NHS, MedlinePlus, NICE, BNF, and other peer-reviewed authorities — not the open internet.
Never diagnoses, never prescribes, never advises stopping medication. Strict guardrails built into every response.
Prescriba remembers your full conversation, so you can ask follow-up questions naturally without repeating yourself.
Describe symptoms, ask about a medicine, or pose any health question naturally — no medical jargon needed.
Prescriba queries its knowledge base of verified content from NHS, Mayo Clinic, NICE, and the BNF — not the raw internet.
Get a clear response with possible explanations, self-care options, when to see a GP, and red-flag warnings.
Tell me what's going on. I'll ask you a few questions to properly understand your situation — just like a real GP consultation.

Prescriba is a health information assistant, not a diagnostic tool. Here is exactly what it does, how it works, and where its hard limits are.
Prescriba is an AI-powered health information assistant that helps you understand symptoms, learn about medicines, and know when to seek professional care. It draws from a curated knowledge base of trusted, peer-reviewed medical sources including the NHS, Mayo Clinic, NICE guidelines, and the British National Formulary.
It is designed for the moments when you're unsure, worried, or simply want to understand your health better — before, after, or alongside a GP visit for non-urgent questions.
If you describe any of the following, Prescriba immediately switches to urgent guidance and directs you to emergency services before anything else. This is built into the AI's core instruction layer and cannot be overridden.
Prescriba is powered by Claude (Anthropic), one of the most rigorously safety-tested AI models available. Rather than drawing from random internet data, Claude is given a strict medical system prompt that enforces cautious language, prevents diagnostic claims, mandates emergency escalation, and anchors every response to authoritative health sources.
