Report side effects of medicinal cannabis

If you use medicinal cannabis or are close to someone who do, you can report side effects (sometimes called adverse reactions) from these products by using our Danish e-form.

Please read the text below and then click on the link to the form to report a side effect you suspect to be caused by medicinal cannabis.

You will find it helpful to have the pack of medicinal cannabis with you to fill in details about the product.

Find the form here.

It takes about ten minutes to fill in the e-form.

If you have questions along the way or cannot use the e-form to make a report, please call us on +45 4488 9595.

Tell your doctor if a side effect happens to you or someone close to you

You should always tell your doctor if you, a relative or someone close to you experiences side effects. Your doctor can assess if the side effect means you should receive a different treatment.

What are side effects?

Side effects are unwanted effects caused by a medicine, in this case medicinal cannabis.

A side effect could be:

• Tiredness
• Dizziness

No systematic studies have been carried out of the types and frequency of side effects of medicinal cannabis.

When you make a report about a suspected side effect, we receive personal information about you that we register and process. Read more about personal information here.

The purposes and the legal basis of the processing of your personal data

We process your personal data for the following purposes:

• The Danish Medicines Agency records all suspected side effects of cannabis end-products in our database of side effects, and we use data about side effects to investigate if there are new or changed product risks.
• The side effect 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.

Categories of personal data

We process the following categories of personal data about you:

• Health data and basic information, e.g. name, initials, CPR (civil registration) number.

Recipients or categories of recipients.

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

• The Danish Medicines Agency's database of side effects, 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.

Transfer to recipients in third countries, including international organisations

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

The data processor, MHRA, used by the Danish Medicines Agency is based in the UK. On 28 June 2021, the European Commission adopted a decision, acknowledging that the UK has an adequate level of data protection and thus is a secure third country pursuant to article 45 of the General Data Protection Regulation.

MHRA, uses a subcontractor, Accenture India, in India.  The Danish Data Protection Agency has authorised the specific transfer of data to a third country by 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.

Storing of your personal data

At present, we cannot say for how long we will be storing your personal data, but it will be retained in the four-year period of the medicinal cannabis pilot programme (1 January 2018 – 31 December 2021). In determining for how long your data should be stored after this period, we will pay special attention to the following:

Your data is retained only for the period necessary to identify and contact you if we need more information to safeguard patient safety. After that, patient details will be anonymised.

Your rights

The General Data Protection Regulation gives you a number of rights to control how we process your personal data. 

You can use these rights by contacting us.

Right to restriction of processing

In certain cases, you have the right to restrict the processing of data held about you. If processing has been restricted, we are – with the exception of storage – only allowed to process these data with your consent, or for the establishment, exercise or defence of legal claims or for the protection of the rights of another person or for reasons of important public interest.

Right to object

In certain cases, you have the right to object to our otherwise legal processing of your personal data.
