Is there any Typical Antipsychotic that won't interact with Clozapine ?

[MedicinalUser247]

I'm currently taking Chlorpromazine as an Antipsychotic for a Medication, but I don't think it's working too well. I'd like to go back on Clozapine, but I'd also like to be taking a Typical Antipsychotic to go with it. When I called the Pharmacy I asked "What Typical Antipsychotic won't interact with an Atypical Antipsychotic ?" and My Pharmacist said "They all interact", but I don't think this is true. I think she's misinformed. I want to go back on Clozapine along with a Typical Antipsychotic. What do you suggest I do ?
