The problem with UK medicines information is not scarcity; it is distribution. The answer to a real question is routinely spread across a national formulary, an exact product SmPC, a local formulary, a monitoring source and sometimes a specialist database, and the clinician's first need is orientation: understanding the medicine's shape well enough to know which detailed source to open. iatroX Medicines is built for exactly that first step: 1,255 published, evidence-linked UK medicine guides at the time of writing (August 2026), searchable by active ingredient, brand or familiar alias, structured identically so that orientation takes seconds. This page is the first-party description of what it is, what it contains, and, as importantly, what it deliberately does not attempt.
What the overview layer contains
Each medicine's overview answers the questions patients and clinicians actually ask first, in plain language: what the medicine is and its main uses; how it works; the preparations and strengths that exist in the UK; how it is taken or administered; side effects, with the urgent warning signs separated from the common nuisances; pregnancy and breastfeeding; the important interactions; common patient questions; and related medicine guides. The index runs from the everyday, amoxicillin, paracetamol, ibuprofen, to newly licensed products, and every page shows its last-reviewed date and names its sources.
What the clinical-detail tab adds
One tab deeper sits the professional layer: prescribing considerations; contraindications and cautions; monitoring; clinical pharmacology; product and formulation differences; and more detailed interaction information, each element linked to its source. The apixaban clinical page is a fair sample: preparations mapped to their own current selected SmPCs, including two distinct oral suspension products; interaction entries, other anticoagulants, antiplatelets, NSAIDs, each carrying links to SPS's DOAC guidance and the relevant SmPC; NHS and MHRA safety sources listed; and the review date visible. The nitrofurantoin clinical page shows the same structure doing harder work: standard versus prolonged-release formulations distinguished, product-specific renal-function wording flagged, and long-term pulmonary, hepatic, neurological and haematological toxicity given proper space.
How sources are displayed, and why it matters
Every page links out, visibly: current selected SmPCs on emc for each preparation; NHS medicines information; SPS where practical guidance exists; UKTIS or BUMPS where pregnancy questions arise; MHRA and government safety communications where relevant. The design position, stated in iatroX's editorial policy, is that structured synthesis should make recognised sources faster and more intelligible, never detach users from them; the medicine page is a front door with the corridors labelled, not a destination that hides the building.
What it does not attempt to do
The boundaries are deliberate. iatroX Medicines does not determine local preference, make patient-specific prescribing decisions or replace specialist advice. It is not a dosing reference: verify the exact product in its SmPC on eMC and use applicable NICE, SPS, local or specialist guidance for the regimen, monitoring and implementation. Every clinical page repeats the working rule to combine authorised product information, local policy and patient-specific assessment.
How the content is reviewed
The editorial method, per the published policy: a defined source hierarchy with UK-authorised and NHS sources at the top; structured retrieval and automated validation against those sources; human review of the static content; a visible last-reviewed date on every page; and a rolling correction and update pathway as products, licences and safety communications change. The review dates are load-bearing, medicines information ages fast, and a page that shows when it was last checked is making a verifiable claim rather than an ambient one.
Frequently asked questions
Is iatroX Medicines free?
Yes, the medicine guides are freely accessible, overview and clinical tabs alike.
Who is it written for?
Both audiences deliberately: the overview reads plainly enough for patients, the clinical tab is professional-facing, and the separation keeps each honest. Prescribing decisions remain with the clinical team either way.
How does it differ from the NHS Medicines A-Z?
The NHS site explains medicines to the public excellently; iatroX adds the professional clinical layer, formulation-level distinctions, and the direct per-product source links, and links the NHS page itself where it helps.
How were the 1,255 medicines chosen?
Coverage prioritises what UK clinicians and patients actually look up, the common prescribing landscape, plus newly licensed products as they arrive, and the index grows on a rolling basis. Gaps can be reported through the site and feed the same update pathway as corrections.
Does it work on mobile?
Yes, the guides are responsive and also reachable through the iatroX iOS and Android apps, which matters because medicines questions are disproportionately asked standing up.
