An unfamiliar overseas medicine creates several questions: what the product contains, which formulation the person is taking, whether a relevant UK product exists and what should happen next. A brand-name match answers only part of that work. The most useful resources address those questions in sequence.
This guide compares Martindale, UK product information, medicines advice and iatroX's reference-and-learning role. Official sources were checked on 10 November 2026. The fictional example concerns resource selection and does not recommend a medicine substitution.
Establish the product before looking for an equivalent
Start with the information available from the original packaging, dispensing label, leaflet and reliable clinical records. Record the country, manufacturer, product name, active ingredient or ingredients, strength, formulation and route. A photograph of one side of a carton may leave important details unresolved.
Separate what is known from what is inferred. For example, a familiar-looking brand name is not evidence that two countries' products have the same ingredients. A strength written as a percentage also needs its units and preparation context. The SPS guide to generic and brand prescribing explains circumstances where brand and formulation details matter in UK practice, including release-profile variations.
The immediate question may be continuity of an established treatment, a possible adverse effect or an unclear medication history. Make that purpose explicit. Identifying a product and selecting an appropriate treatment plan are connected but separate decisions.
Choose the resource for the information layer
| Question | Resource to use | Useful result |
|---|---|---|
| What is this overseas preparation? | Martindale and available manufacturer or national product information | Verified ingredients and preparation details for the correct country |
| What does a relevant UK product's licence say? | eMC or the applicable UK product information | The exact SmPC and patient leaflet |
| Do product or release-profile differences affect the proposed plan? | Relevant product documents and specialist medicines advice | A reasoned assessment of the unresolved difference |
| Does supply require an unlicensed or imported product? | Local pharmacy/procurement expertise and applicable guidance | A documented supply route and responsibilities |
| How do I understand the medicine in UK practice? | iatroX Medicines and Ask | A structured explanation linked to supporting sources |
| What should I learn from the recurring uncertainty? | iatroX Tutor or CPD | Targeted practice, reflection and a useful learning record |
A search result can help locate a source. Keep the verification tied to the identified product, rather than allowing a familiar generic name to erase uncertainty about the actual preparation.
Martindale: international preparation identification
Martindale: The Complete Drug Reference is specifically relevant to international medicines enquiries. Pharmaceutical Press describes navigation between proprietary preparations and drug monographs, synonyms and identifiers, and a flagging system for preparations sharing a name but containing different ingredients.
Those features make Martindale a useful resource to assess for an overseas-brand enquiry. Search using the country and available preparation details, then check whether the result accounts for everything on the original pack. If the preparation is missing or the details disagree, keep that discrepancy visible and seek further information.
There is also an access distinction worth knowing: the publisher says the 41st edition is the final print edition, with future updates available online. An older printed entry may help orient an enquiry, but it should not be described as equivalent to current online content. Check whether your organisation subscribes to the relevant MedicinesComplete resource.
eMC and specialist advice: move from identity to a UK plan
eMC hosts UK licensed product information, including SmPCs and patient leaflets, and allows searching without registration. Once the ingredient is established, find the exact relevant UK product and inspect its strength, formulation and instructions. eMC's absence of an overseas brand is not, by itself, evidence that the original medicine was misidentified.
The comparison may reveal an unresolved question about release profile, route, availability or the proposed change in therapy. Formulate that question for the appropriate pharmacy or medicines-advice service. Include the confirmed product details, the clinical purpose and the specific uncertainty rather than asking only for a “UK equivalent”.
SPS Medicines Advice offers a clinical enquiry service for healthcare professionals in primary care, including community pharmacy, in England. Hospital staff and clinicians elsewhere should use their applicable service route. Check current eligibility and contact arrangements at the source.
If an imported or unlicensed supply is being considered, involve the relevant pharmacy and procurement team. SPS guidance on purchasing specials explains that supplier and import requirements are distinct from finding a medicine in a reference. A database entry does not establish that a particular supply route has been arranged.
iatroX gives the enquiry a clear learning outcome
iatroX Medicines helps clinicians and learners build a concise, source-linked understanding of medicines used in UK practice. Once identity is established, it is a useful place to explore the ingredient's clinical context and frame the next question. Ask iatroX is free and supports focused UK clinical reference questions.
A good learning question might be why a formulation distinction matters, which product information needs checking or how to describe an uncertainty to a pharmacist. Take that gap into iatroX CPD for targeted questions, Tutor discussion, a personalised reviewed reflection and an exportable record. The practical benefit is a repeatable approach to the next unfamiliar product, with evidence of what you learned.
A fictional medicines-reconciliation enquiry
Imagine a pharmacist reviewing an overseas carton whose brand resembles a familiar UK name. The patient describes a once-daily tablet, but the visible photograph does not establish whether it is modified release.
The pharmacist first obtains the missing packaging and reliable dispensing details. They use Martindale or appropriate national/manufacturer information to establish the original preparation, then inspect the relevant UK product information. If the release characteristics remain uncertain, they ask a focused specialist question before the responsible clinician agrees a plan.
Afterwards, the pharmacist uses iatroX to revisit the clinical significance of formulation differences and records the learning through a targeted session. The fictional example's successful output is a verified medicine history and an explicit decision process, not an automatic substitution produced by a brand search.
Frequently asked questions
Can the same brand name contain different ingredients in different countries?
It can. Martindale's publisher explicitly describes a flagging system for that situation. Verify the country and preparation rather than relying on name recognition.
Is eMC a worldwide brand-name directory?
Its stated scope is UK licensed medicines information. Use an appropriate international or national source for the overseas preparation, then use eMC for the relevant UK product.
Does identifying the ingredient establish a suitable UK substitute?
It establishes one essential part of the enquiry. Formulation, route, clinical purpose and supply arrangements may still need assessment and agreement through the appropriate clinical team.
