What a medicines review can—and cannot—tell you
A calm guide to what a high-quality review covers, what information it needs and where your GP still comes in.

In brief
- A review should consider safety, effectiveness, monitoring and what matters to you.
- Its quality depends on having an accurate list and enough clinical context.
- A review supports decisions with your prescriber; it does not replace diagnosis or prescribing.
More than an interaction check
A useful medicines review looks across the whole list. It asks whether each medicine still has a clear purpose, whether the dose and combination remain sensible, whether monitoring is up to date and whether side effects or practical difficulties are getting in the way.
It should also make space for your priorities. A medicine can be clinically appropriate and still create a burden that deserves a conversation. NICE describes medicines optimisation as a person-centred approach, and NHS England says structured reviews should consider benefits, risks, alternatives and the individual’s circumstances.
The information that changes the answer
Names and doses are only the beginning. Allergies, kidney and liver function, recent blood tests, the reason a medicine was started, previous reactions and medicines bought without a prescription can all change what a pharmacist concludes.
An independent online service will not automatically see your GP record. If important information is missing, the safe answer may be to ask for it or describe the uncertainty rather than make a confident recommendation.
- Include prescribed, over-the-counter, herbal and complementary products.
- Record the strength, dose and how often you actually take each item.
- Mention recent hospital stays, falls, side effects and medicines that were stopped.
- Never stop or change a medicine without speaking to the appropriate prescriber.
What the final report should do
The most useful output is not a frightening catalogue of theoretical risks. It is a prioritised explanation: what looks reassuring, what needs a routine conversation, what monitoring may be due and what—if anything—needs prompt attention.
A report can help you prepare for an appointment, but your prescriber still has the fuller clinical record and responsibility for treatment decisions. That boundary is a strength, not a limitation to hide.
