Introduction
It is recommended to wait approximately one hour after taking calcium gluconate and zinc sulfate oral solution before taking clozapine. For patients with concurrent deficiencies in calcium and zinc as well as schizophrenia, and who have no history of drug allergy, combination therapy may be used under medical supervision. The calcium gluconate and zinc sulfate oral solution helps supplement calcium and zinc, while clozapine tablets are used to treat schizophrenia. Using both medications together addresses both nutritional supplementation and disease management.

Combination use is contraindicated if the patient is allergic to any component of calcium gluconate and zinc oral solution or clozapine, or has severe liver or kidney dysfunction or other contraindications.
