Do you insist on conventional medications being stopped before treatment?

Never. It is important to remain on your current medications and only to reduce or withdraw them under the advice of your prescribing medical doctor.  The homeopathic remedies will still work effectively even if you are already on prescribed medications.  Once your health stabilises, you can work with your medical doctor to reduce and/or remove your medications.  It is not safe to remove prescribed medications without proper advice.
