  The only adverse event that met the threshold of incidence ≥5% for valbenazine and a rate of ≥2 times than that observed with placebo was somnolence (somnolence, fatigue, sedation), with rates of 10.9% for valbenazine (all doses) vs 4.2% for placebo, [ncbi.nlm.nih.gov]

  Studies of valbenazine show it to be well tolerated, with fatigue or sedation as the main side effect. More common side effects of deutetrabenazine are akathisia (restlessness), depression, and diarrhea. [everydayhealth.com]

  Because PNKD may be triggered by emotional stress, fatigue, alcohol or caffeine, the avoidance of these possible precipitating factors is recommended. Deep brain stimulation may act as a potential therapeutic option in medically refractory PNKD. [orpha.net]

• Respiratory Distress

  If a patient receiving antipsychotic medication presents with symptoms of tachypnoea or acute respiratory distress, the possibility of respiratory dyskinesia should be considered, since it is a potentially reversible condition. [research.regionh.dk]

  Subjects with visible facial dyskinesia, facial tremors, or evident muscle rigidity in the upper extremities were excluded from study. The most common adverse event observed was an increase in dyskinesias. [dictionary.cambridge.org]

  It’s caused by muscle rigidity. Often begins in the legs and neck. These muscles become very stiff. When it affects the muscles of the face the individual adopts a mask-like stare. Bradykinesia slowness of motion. [timeofcare.com]

  Second-level treatment options include clonazepam, which is sometimes given as a short-term medication for muscle rigidity. People have also found relief from the herbal supplement gingko biloba. [nami.org]

• Dystonia

  Dystonias A dystonia is a sustained muscle contraction, frequently causing repetitive twisting movements or abnormal postures [ 1, 2 ]. [patient.info]

Strategies for prevention A number of preventive measures have been suggested to reduce TD risk. Patient and/or caregiver risk-prevention education is imperative before initiation of antipsychotic therapy. [psychiatrictimes.com]

Prevention Because there is no “gold standard” treatment for TD, it is important to minimize the risk of TD by taking preventive measures and detecting incipient signs of the disorder. [mdedge.com]
