Hi, Thanks for posting in HCM. I understand your concern. Ziprasidone is an atypical antipsychotic medication. It is used for the treatment of schizophrenia and acute mania as well as mixed states associated with bipolar disorders. Sleepiness and headache are very common adverse effects associated with intake of this medication. Other C side effects include: excessive salivation or having dry mouth, runny nose, cough, nausea, vomiting, stomach aches, constipation or diarrhea, loss of appetite, weight gain, skin rashes, fast heart beats, blood pressure falling when standing up quickly, muscle pain, weakness, twitches, dizziness and anxiety. You need to seek medical attention promptly if such side effects continues to bother you or worsen. Hope the information provided would be helpful. All the best.
