Patient's Query

Hi doctor,

My father is having constant uneven movement of the mouth for the past three months. He feels like he is chewing which is really irritating him. Kindly help me on that.

Hello,

Welcome to icliniq.com.

This can be the side effects of the pills he is having. So let me know the list of entire medicines he is having. If not, then he will need neurological evaluation. Also, let me know if he is having any other symptoms elsewhere in the body like weight loss or blood in stool, constipation, etc.

I hope this helps.

Thank you.

Patient's Query

Thank you doctor,

Really appreciate your reply. I am attaching you the medicines he is having right now.

Hello,

Welcome back to icliniq.com.

I have gone through the medicines attached (attachment removed to protect patient identity). There are three medicines he is having, Mozep (Pimozide), Pacitane (Trihexyphenidyl) and Remeron (Mirtazapine), which are antipsychotic medicines. All of these medicines can cause these movements as side effects.

What was the indication to start all these medications? So, need to stop these medications. You please discuss with the doctor regarding stopping these medications and also their need.

I hope this helps.

Thank you.

Patient's Query

Thank you doctor,

I will look for those three medicines. I referred a neurologist and he has prescribed these medicines which I forgot to update you. I am attaching them.

Hi,

Welcome back to icliniq.com.

I have gone through the details (attachment removed to protect patient identity). I guess two of the medicines Mozep and Pacitane were started a month back while he was already taking Remeron which may cause these movements. Do you know since when he was on Remeron? Do you have any previous prescriptions? If he is currently taking these medications, then you need to discuss with your neurologist regarding these medications aggravating the problem.

Usually, such movements mainly occur as a side effect of antipsychotic medicines, sometimes with age and age-related brain damage which is seen on MRI (attachment removed to protect patient identity). So we should rule out the medicines induced movements, and these may take up to six months to resolve. If you can make a list of medicines which he was having before the problem onset, we can be sure of what exactly the cause for this is and identify the culprit medicine. He should avoid anti-vomiting medicines (Metoclopramide) as well.

I hope this helps.

Thank you.

Same symptoms don't mean you have the same problem. Consult a doctor now!
