thank you for your query. Zeldox contains Ziprasidone, an atypical antipsychotic. Among the side effects reported with this drug are mild Extrapyramidal symptoms (this includes Tremor, rigidity, Parkinsonism like sx etc.), cardiac problems like QTc prolongation (arrhythmia, palpitation, skipped beat etc), lightheadedness, restlessness may occur. On the sunny side though, it cause almost no weight gain, very minute chance of diabetes, and sedation is comparatively less than most antipsychotics. Moreover, it also has properties to manage mood symptoms, both mania and depression. However, as with most antipsychotics, you need to give it a few weeks to start its action. Prestiq (Desvenlafaxine, an antidepressant) and Seroquel (Quetiapine, an atypical antipsychotic and mood stabiliser) are standard medications used for treatment of anxiety, depression and bipolar disorders. I would suggest you not to worry, take your medications as prescribed, and contact your psychiatrist urgently if you have any trouble with them. hope i ve been able to satisfy your query. please don t hesitate to contact me for any further clarifications.
