How Medicine Information on MayChemist Is Researched

Medicine information earns its place only when a reader can trace where it came from. MayChemist publishes for people in Malaysia, including readers who live far from a pharmacy with wide stock. Generic products supplied by pharmacy partners may carry names, strengths and pack sizes that differ from what a reader has met before. Explaining those differences is the work, and guesswork has no part in it.

The order in which sources are trusted

Sources are not interchangeable, so they are ranked. Researching a medicine, a national rule or a safety warning, we start at the strongest material and work down:

1. Medicines regulators and national health authorities.
2. Manufacturer documents, including the patient leaflet.
3. Public health bodies and clinical reference works of recognised standing.
4. Drug databases, pharmacopoeias and the systems that name ingredients.
5. Respected medical publishers or specialist references, used only where official material leaves gaps.

A regulator’s own record or a manufacturer’s leaflet outranks a summary of them, however readable that summary is. Anonymous health blogs, forum threads, thin affiliate pages, social media assertions and drug facts lifted from another site without a source are not used at all.

Medicine pages and the checks behind them

A medicine page sets out what the product is, what it is taken for, and which brands or generics a reader may meet. Before publication we confirm:

• the active ingredient;
• brand names in common use;
• other generic versions;
• the strength and the form it comes in;
• who makes it;
• whether a leaflet or product summary exists;
• relevant records held by regulators or drug databases;
• how the product differs from one country to another.

Naming medicines by ingredient

Brand names shift across borders; ingredient names travel better. A product familiar in Malaysia under one name may reach a reader as an Indian branded generic with a different name, or under a third name in the country where it was first taken. Two packs with different branding can hold the same medicine, and the ingredient name is how that becomes visible. Comparison therefore begins with the active ingredient. Where we can, we follow the International Nonproprietary Names system of the World Health Organization, known as INN, which identifies a substance by one shared generic name rather than a local brand.

Ingredient, condition and category pages

Pages about an ingredient, a condition or a category answer practical questions:

• what an ingredient does and what it is used for;
• which medicines are used for a condition, and how they differ from one another;
• how a branded product compares with its generic;
• why one medicine can appear under several names.

Statements on these pages that hinge on a country’s rules get closer checking than general medicine facts.

Where a country check begins

When a claim depends on the rules of a particular place, the check starts with that place’s medicines regulator or health ministry rather than with somebody else’s summary. These are the sources we turn to first.

Authority or database	What is checked there
National Pharmaceutical Regulatory Agency (NPRA)	product records in QUEST3+, the Ministry of Health Pharmaceutical Services Programme and InfoSihat health education
Health Sciences Authority	medicines information for Singapore
Therapeutic Goods Administration	medicines guidance, the ARTG search and healthdirect medicines information
Medsafe	medicines information for New Zealand
Central Drugs Standard Control Organization	the CDSCO online portal for India
MHRA	MHRA Products for the United Kingdom
European Medicines Agency medicine finder	national medicine registers across the European Union
FDA Drugs	MedlinePlus drug information for the United States
WHO International Nonproprietary Names	international naming of substances

Rules about medicines are made nationally. Something true in one market does not carry over by itself, and a product sold in one country is not thereby accepted in another. Prescription handling differs between countries too.

Brands, generics and the differences that matter

Comparison starts with the active ingredient, not the marketing name. A generic can share that ingredient with an original brand and still differ in practical detail:

• who manufactures it;
• what the tablet looks like;
• the inactive ingredients;
• how many units come in a pack;
• the name it carries locally;
• its registration position;
• which country supplies it;
• the strengths on offer;
• the price.

A reader weighing two products can use the ingredient name to check whether the comparison is like for like. Being generic is no reason to dismiss a product, and being branded is no reason to prefer one. What counts is the ingredient, the manufacturer, the regulatory position, the product information available and the route by which it is supplied. This matters most with Indian generics. India makes medicines at great scale, yet quality depends on the particular firm, the product, the market authorisation and the supply chain. Blanket approval and blanket suspicion both miss the point.

Registration is a national fact

Whether a medicine is registered is a fact about one country, not a verdict on the product. A product with no registration in a given market is not for that reason unsafe, counterfeit or ineffective. The maker may never have applied there, the product may be sold there under another name, the market may be too small, or the regulator may have decided otherwise.

Where registration matters to a reader, we try to say:

• where the medicine is registered;
• where it is missing or appears unavailable;
• whether the same ingredient can be found there under another name;
• which regulator or database was consulted;
• whether the question is medical, regulatory or commercial.

Scare language is avoided, and one regulator’s position is not turned into a judgement about the rest of the world.

Claims, links and figures

Before a page goes up, each important factual claim is matched to a suitable source. That covers statements about:

• what a medicine contains;
• prescription status;
• registration;
• rules for import or travel;
• official warnings;
• safety restrictions;
• pharmacy rules that apply in a given country;
• differences between brands and generics;
• manufacturer information;
• public health guidance.

Where support is missing, the claim is cut, weakened, or marked plainly as uncertain.

A source link should take a reader to the material that backs the sentence. Links are checked by hand where needed. Official health websites occasionally refuse automated tools, relocate pages, or use search functions that behave unlike ordinary web pages, so a failed automated check is not treated as proof that a source has gone. If a source really has disappeared, gone out of date, or stopped supporting the sentence, the source is replaced or the claim removed.

Numbers age badly. Thresholds written into law, limits on what may be imported, courier limits, prescribing rules, prices and registration entries can all shift without much warning. Where a figure is likely to move, we would rather point to the official page or say what a reader should check than print a number that will mislead later. Figures are not invented, whether a market size, a success rate, an approval count or a delivery promise. A figure on MayChemist comes from a named source, reflects a current product value, is marked approximate, or carries a date where timing matters.

When sources disagree

Sources can contradict one another. The authority closest to the question wins:

• for national rules, that country’s regulator;
• for product detail, official documentation from the manufacturer;
• for general medicine information, recognised clinical references;
• for travel and import questions, customs or health authority guidance.

Where a disagreement changes what a reader should understand, it is set out rather than hidden.

What is not published

You will not find here:

• instructions for diagnosing yourself;
• treatment decisions made for an individual;
• false certainty about legal rules;
• claims of miracle effects without support;
• flattery of generics or of brands;
• manufacturer marketing reproduced as neutral advice;
• medical claims resting on reviews, forums or social media;
• assurances that a medicine suits a person without professional review.

MayChemist is a guide to information and access. It cannot stand in for a doctor, a pharmacist, or emergency care.

Plain writing and professional decisions

Clear writing is the point, because medicine information is hard enough already. Clarity is not the same as trimming away what matters. A useful guide should leave a reader knowing:

• what the medicine is for;
• which ingredient does the work;
• which brands and generics exist;
• what a different strength or pack size means;
• what to ask before deciding;
• when a doctor or pharmacist should be brought in.

The choice of treatment belongs with a qualified professional, particularly for prescription medicines, long-term conditions, pregnancy, children, allergies, interactions and serious symptoms.

Review dates, corrections and the standard kept

Medicine information moves. Brand availability, prices, regulator pages, leaflets, import rules and pharmacy requirements all change. Content is dated and reviewed where timing matters, and pages are revised when the sources change. Dating matters most for anything a reader could check against a page that is itself updated.

If something is out of date, unclear or wrong, use the Contacts page to report it. Correction reports are reviewed and pages updated where needed.

The standard is this. A reader should be able to:

1. find a medicine by its active ingredient rather than its brand name;
2. weigh brands, generics, strengths and differences between countries without so much confusion;
3. tell which statements are sourced, which rules could shift, and when professional advice is needed.

That standard covers medicine pages and the ingredient, condition and category pages alike.
