Medical information: scope and limits

Your clinical context matters

A prescriber considers factors a website cannot assess: medical history, examination findings, other medicines, pregnancy plans, tests, symptoms, tolerability and follow-up. General information about a licensed treatment does not establish that you meet its criteria or should use it.

Products sharing an active ingredient can differ in licence, strength, route, device and instructions. Brand names and pack presentations must not be substituted on the basis of a general explanation. Read the patient leaflet provided with your medicine, and ask the pharmacist if the pack differs from what you expected. NHS patient information also directs people to the relevant product instructions and professional support. [1]

Tools and trial averages have limits

Pen-cost tools use labelled injection counts and entered prices. They cannot confirm that a seller is legitimate, that a medicine has been stored correctly or that a particular dose is right. They do not calculate an injection dose from clicks.

The protein tool displays a chosen weight-based estimate. It is not a nutritional assessment and is not designed for clinical diets or people whose circumstances need specialist advice.

Trial averages describe groups under a study protocol. They do not predict an individual’s weight change or the balance of benefit and risk. Results depend on population, treatment, comparator, follow-up and analysis. Read the source and the explanation around a figure rather than treating it as a promise.

Seek clinical help for urgent symptoms

Severe, persistent abdominal pain, particularly if it reaches the back or occurs with vomiting, needs urgent medical assessment. MHRA guidance highlights this warning in relation to pancreatitis with GLP-1 medicines. Do not use a website form or wait for an email reply about these symptoms. [2]

Call 999 for a life-threatening emergency such as severe breathing difficulty or collapse. For urgent help that is not immediately life-threatening, use the appropriate urgent-care service where you are. In England, NHS 111 can help when you are unsure where to get urgent care. The side-effects guide gives further context. [3]

Suspected side effects can also be reported through the MHRA Yellow Card scheme. A safety report is not a substitute for urgent care. [4]

Access rules and external services

The website focuses on UK readers, but prescribing pathways and NHS commissioning differ across the four nations and local services. A NICE recommendation or regulatory announcement does not guarantee an immediate prescription.

External sites have their own content, terms and privacy practices. A link is not a clinical endorsement or a guarantee that every claim on that site is accurate. Use official registers and contact a qualified professional when the decision concerns a medicine or your health.
