If the doctor prescribes generic compounds, he knows that they are products that can be trusted: same active ingredient, same efficacy, same safety of use as the original compounds. A patient cannot refuse a prescription for a generic without medical or clinical justification. It is up to him to talk about it with his doctor, who can explain the reasons for his choice, hear his fears and respond to them. Suppose the doctor considers that for particular reasons relating to the state of health of his patient, it is justified not to prescribe a generic. In that case, the doctor will note "not substitutable" on the prescription accompanied by the medical reason that authorizes this refusal of substitution, using an acronym.
