The General Medical Council (GMC) has produced new guidance for the ways in which doctors seek patient consent.
According to the BBC, the group's approach highlights the need to share information regarding side effects and outlines good practice for dealing with patients with dementia.
Speaking to the news provider, GMC head of standards and ethics Jane O'Brien said: "We would like to remind doctors and get them to see that consent is what the patient does, not what they do."
She added that doctors need to engage more with patients in order to make the best decisions.
The British Medical Association has lent its support to the guidelines, but has expressed concern that they could place an extra burden on medical professionals.
Meanwhile, it was recently reported that a consultation has been launched to explore the ethical issues related to dementia.
The Nuffield Council on Bioethics hopes the consultation, which will cover living wills among other issues, will help families, carers and professionals make the best decisions for people with dementia.
