If you are going to contact a pharmaceutical company to either discuss a medicine or report a suspected side effect, please make sure that you contact the company that is responsible for the medicine you're actually using. Their contact details can be found on the product pack and in the Patient Information leaflet with the medicine. They can also be found on emc by clicking the 'Contact details' link displayed under the medicine name and at the bottom of every document:
You can see a full list of the companies that contribute by choosing 'COMPANIES' from the top menu bar and then selecting the option 'Show All' or through the following link - https://www.medicines.org.uk/emc/browse-companies. Contact information for each company is available at the top of each company page.
Often several companies will manufacture the same medicine but the prescribing information in the Summary of Product Characteristics (SmPC) may differ. For example, the medicines may have different excipients, formulations, licensed indications or contraindications for use. The information in the SmPC only relates to that company's medicine and it cannot be assumed that it is applicable to a product from any other company. Accessing the right information is essential for patient safety.
