Personalizing treatment for tardive dyskinesia (TD) requires a patient-centered approach that carefully considers the individual’s symptom patterns, medication history, and overall health status. Both VMAT2 inhibitors available show similar efficacy regardless of the body regions affected by abnormal movements, so the choice of treatment is not typically driven by symptom location. Clinicians focus on understanding how these movements impact the patient’s quality of life and work to simplify and optimize the medication regimen. This often involves reviewing concurrent medications to reduce unnecessary drugs, such as anticholinergics, and closely monitoring for potential drug interactions, especially those involving liver enzymes like CYP2D6 and CYP3A4. Factors such as liver and kidney function, as well as patient age, inform dosing decisions; however, age is considered a guideline rather than a strict determinant due to the variability in individual physiology.

In patients with comorbid psychiatric conditions requiring ongoing antipsychotic treatment, managing TD becomes more complex. The primary goal is to maintain psychiatric stability using the lowest effective dose of antipsychotics or considering alternative therapies when possible, especially in mood disorders where options may be more plentiful. For conditions like schizophrenia, alternatives are more limited. Importantly, VMAT2 inhibitors have demonstrated beneficial effects not only on movement symptoms but also on psychiatric symptoms, often working synergistically with antipsychotic medications. While discontinuing the causative antipsychotic is ideal when feasible, it is rarely possible in chronic TD cases. Most patients continue to require antipsychotics, and the addition of VMAT2 inhibitors helps manage TD symptoms while supporting psychiatric care.

Ongoing assessment and dose optimization are critical components of long-term TD management. Regular evaluations using symptom rating scales alongside patient discussions about the impact of symptoms and adverse effects guide individualized dose adjustments. Pharmacists and clinicians play key roles in these assessments during routine patient visits, including those for injectable antipsychotics. This personalized, dynamic approach ensures treatment is both effective and tolerable, aiming to improve overall quality of life while addressing the complexities of comorbid conditions and polypharmacy.
