Getting started

We use the details you provide to build a clear picture of the adverse reaction you report. You must fill in the fields marked with a red star in the e-form, but it is of great help to us, if you fill in as many fields as possible.

It takes about ten minutes to fill in the e-form. If you have questions along the way, please call us on +45 4488 9595.

What to include in an adverse reaction report

When you report a suspected adverse reaction to the Danish Medicines Agency, it is important to include at least the following details:

  • Identification of the suspected cannabis product.
  • Indication and dose.
  • A description of the suspected adverse reaction.
  • One or more details about the affected patient: date of birth, civil registration number (CPR no.), gender, age or initials.
  • Identification of the reporter.

A report submitted by a doctor should as far as possible contain information about the patient’s civil registration number (CPR no.), method of administration of the cannabis product, and the batch number of the cannabis intermediate product manufacturer.

In some cases, we may need to obtain additional information on the report. If so, we will contact you to obtain the necessary information.

When you make a report about a suspected adverse reaction, we receive personal data about you, which we register and process. We register your basic information, such as name, workplace and contact details in case we have follow-up questions to your report.

According to article 13 of the General Data Protection Regulation, we must provide you with a number of details. The details we must give you are:

We process your personal data for the following purposes:

  • The Danish Medicines Agency records all suspected adverse reactions of cannabis products in our database of adverse reactions, and we use data about adverse reactions to investigate if there are new or changed product risks.
  • The adverse reaction data will be used for our monitoring and evaluation of the four-year medicinal cannabis pilot programme.

The legal basis for our processing of your personal data follows from:

Part VIII of Danish Act no. 1668 of 26 December 2017 on a Medicinal Cannabis Pilot Programme, and Danish Executive Order no. 1732 of 26 December 2017 on the Reporting of Adverse Reactions from Medicinal Cannabis and Processing of Adverse Reaction Reports.

We process the following categories of personal data about you:

  • Basic information such as name, title and workplace.

We disclose or transfer your personal data to the following recipients:

  • The Danish Medicines Agency's database of adverse reactions is a database established and operated by the British Medicines and Healthcare products Regulatory Agency (MHRA). The Danish Medicines Agency thus uses the MHRA as a data processor.

Your personal data is transferred to recipients outside the EU and the EEA.

The Danish Medicines Agency's data processor, MHRA, uses a subcontractor, Accenture India, in India.

The Danish Data Protection Agency has authorised the specific transfer of data to a third country in its authorisation dated 8 October 2010, cf. article 46(5) of the General Data Protection Regulation. You can request a copy of the authorisation granted by the Danish Data Protection Agency by contacting us.

At present, we cannot say for how long we will be storing your personal data, but it will definitely be stored throughout the duration of the four-year period of the medicinal cannabis pilot programme (1 January 2018 – 31 December 2021). When it is to be decided for how long your data will be stored after the four-year period, the following will be emphasised:

– that your data are stored for as long as it is relevant for reasons of patient safety to identify you to pose follow-up questions. After that, the patient details will be anonymised.
