Can I demand specific treatment?

No. A doctor does not have to prescribe a medication or treatment, if they don't think it's the right option for you. However, you are entitled to ask for their reasons. There is also nothing to stop you making a suggestion, and explaining to your doctor why you believe it's a good option.

You have the right to refuse a particular drug or treatment if you don't feel comfortable with it. If you feel uncomfortable about your doctor's suggested treatment, always discuss your concerns with them. They should be able to give you all of the information you need, such as the possible side effects, which will allow you to make an informed decision.

If you are not totally satisfied with the advice of your doctor, you may consider getting a second opinion. You may feel happier with a different doctor, but be aware that they may give the same advice as your original doctor. If you are given the same advice, you are still entitled to refuse the suggested treatment.
