No.
Your doctor cannot stop you taking any over the counter medication or having any non-NHS treatment you wish to treat any health condition you may have.
However, they can refuse to prescribe medication or offer treatment frrom the NHS, should they be able to demonstrate, when questioned, why that particular prescribed medication or treatment would not be suitable for your needs.
There is case law that doctors must observe when discussing treatment options with a patient, that currently is The Montgomery Case 2014.
The case makes it clear that:
- Doctors are required to discuss all options available if they are appropriate/reasonable in a particular patient's case
- Doctors are expected to offer any and all treatments that can be found globally/in research settings
- If a patient requests a treatment/procedure that they do not think is a reasonable or appropriate option, they can refer on to another clinician for a second opinion.
The GP is also bound by his professional body, The General Medical Council (GMC), to ensure that:
- making the care of patients is their first concern
- they provide a good standard of practice and care, and work within their competence
- they work in partnership with patients and support them to make informed decisions about their care
The above guidance is laid out in the GMC`s Good Medical Practice
