Users of medicinal cannabis (cannabis products) and relatives can report side effects to these products by using our Danish e-form.

Please read the text below if you want to report a suspected side effect to medicinal cannabis (cannabis product). Then click the link at the bottom of the page to access the reporting form.

Getting started

Before you fill in the e-form, there are a few things you should know.

We use the details you provide to build a clear picture of the side effect you or someone else has experienced. It is a great help if you complete all fields as precisely as you can.

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

It takes about ten minutes to complete the e-form.

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

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

Contact your doctor if you or your relative experience a side effect

You should always contact your doctor if you or your relative experience side effects. Your doctor can assess whether the side effect should lead to a change in treatment.

What is a side effect?

A side effect (sometimes called an adverse reaction) is an unwanted effect caused by medicinal cannabis (cannabis product).

A side effect could be:

  • Sleepiness
  • Dizziness

No systematic studies have been made of the type of side effects caused by medicinal cannabis or how common they are.

The Danish Medicines Agency has prepared guidelines for doctors on the treatment of patients with medicinal cannabis comprised by the pilot programme (in Danish). The guidelines include information about side effects.

Recipients of categories of recipients

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