The active ingredient is the chemical in the medicine that makes the medicine work. The active ingredient is also known as the generic name or the non proprietary name. Medicines can have more than one active ingredient.
The ATC code is a code assigned to a medicine according to the organ or system it works on and its mode of action. The classification system is maintained by the World Health Organisation (WHO). The active substances within a medicine are classified in a hierarchy with five different levels.
- The system has fourteen main anatomical/pharmacological groups or 1st levels
- Each ATC main group is divided into 2nd levels which could be either pharmacological or therapeutic groups
- The 3rd and 4th levels are chemical, pharmacological or therapeutic subgroups and the 5th level is the chemical substance
Some Summaries of Product Characteristics and Patient Information Leaflets have an inverted black triangle symbol displayed at the top of the medicine information and next to the medicine name. This symbol shows that the medicine is under 'additional monitoring', probably because it is new or is being used to treat new medical conditions. Healthcare professionals are asked to report any suspected adverse reactions via the Yellow Card Scheme at: www.mhra.gov.uk/yellowcard. The black triangle is removed when the safety of the medicine is well established.
CHM stands for the Commission on Human Medicines. The CHM monitor the safety of medicines and encourage healthcare professionals and patients to report all suspected adverse drug reactions using the Yellow Card Scheme. The CHM used to be called the CSM - the Committee on Safety of Medicines.
The pharmaceutical company has decided to discontinue this product. Other preparations of this medicine may still be available. This information has been left on emc for reference purposes.
EMA stands for the European Medicines Agency. This is a government agency which approves and licenses medicines, allowing them to be prescribed in European countries.
An ePIL is a text only version of the original patient information leaflet, which is formatted for use by the visually impaired. ePILs are created in XML (Extensible Mark-up Language) format. XML is an industry standard computer file format that allows data to be shared between systems and displayed in different ways. This enables screen readers to read the ePILs; in addition the ePILs can be converted to Braille, audio CD and large print formats.
Every medicine has a legal category. POM means prescription only medicine - you can only get the medicine on prescription. P means pharmacy - you can only get the medicine from a retail pharmacy. GSL means general sales list - you can buy the medicine without a pharmacist, for example in a supermarket. CE Mark is used on devices.
GSL stands for general sales list. If a medicine has this legal category, it can be bought in a shop without a pharmacist, for example in a supermarket.
P stands for pharmacy. If a medicine has this legal category, it can be bought from a retail pharmacy shop in the presence or under the supervision of a pharmacist.
POM stands for prescription only medicine. If a medicine has this legal category it can only be obtained on a prescription from a healthcare professional.
MHRA stands for Medicines and Healthcare products Regulatory Agency. This is a UK government agency which approves and licenses medicines, allowing them to be prescribed in the UK.
A new medicine is an SmPC or PIL which has never been published on emc before. This could be because it is a brand new product or it is an existing product which the pharmaceutical company has just decided to add.
PIL stands for Patient Information Leaflet (known as Package Leaflet or PL) and is the leaflet that is included in the pack with a medicine. The PIL is written by the pharmaceutical company and is a patient-friendly version of the Summary of Product Characteristics. All PILs are checked and approved by the UK or European medicines licensing agency. If you are unsure about anything or have any questions about the PIL, always speak to a healthcare professional such as a doctor, pharmacist or nurse.
PILs have to contain specific headings, but sometimes the order might differ. These are the usual headings and the information that is included in each section.

emc contains two types of regulated information - the Summary of Product Characteristics (SmPC or SPC) and the Patient Information Leaflet (PIL). Both the SmPC and PIL are approved by the medicines' regulators.
There are two medicines' regulators. The MHRA (Medicines and Healthcare products Regulatory Agency) is a UK government agency which approves and licenses medicines, allowing them to be prescribed in the UK. The EMA (European Medicines Agency) is a government agency which approves and licenses medicines, allowing them to be prescribed in European countries.
Report a side effect with the Yellow Card Scheme
Report a side effect with the Yellow Card Scheme
emc and pharmaceutical companies, who provide the information on our website, encourage you to report all suspected problems or incidents, including side effects that you suspect might be associated with a healthcare product or device. These problems also include defective and counterfeit/fake products.
Healthcare professionals and patients themselves can report suspected problems using the Yellow Card Scheme website, which is run by the Medicines and Healthcare products Regulatory Agency (MHRA), a UK government agency monitoring medicines.
Comprehensive reporting and monitoring should lead to the safer use of medicines and devices, whilst also helping to improve public health.
Discover more about reporting suspected problems by visiting the MHRA website here.
Where a medicine is shown as 'Retired' it means the SmPC and/or Patient Leaflet has been removed from emc, either by the pharmaceutical company or, occasionally, by Datapharm. There are many reasons why an SmPC or PIL would be removed and a summary is given on the change history page for that product.
Risk Minimisation Materials (RMMs)
Risk Minimisation Materials (RMMs)
Risk Minimisation Materials (RMMs) are part of an overall Risk Management Plan that uses a number of measures throughout the life of a product to optimise the safe and effective use of a medicine. RMMs can come in a number of forms, such as educational programmes, prescribing or dispensing guides, patient brochures or alert cards and letters directed at healthcare professionals. Risk Minimisation Materials on this site are approved by the UK or EU regulatory authority.
SmPC, or SPC, stands for Summary of Product Characteristics. The SmPC is used by healthcare professionals, such as doctors, nurses and pharmacists, and explains how to use and prescribe a medicine.
SmPCs are written and updated by pharmaceutical companies and are based on their research and product knowledge. The SmPC is then checked and approved by the UK or European medicines licensing agency. SmPCs have to contain certain numbered headings and information. We now explain, in simple terms, what the headings mean and what each section contains.
