Question: My granddaughter istaking repedril (sp?) for mania as she has been diagnosed with bipolar disease. She is acting more normal but walks rather strangely, kind of robotic with her elbows very close to her sides and her head very stiff. Are these side effects dangerous or are they things that can be expected with this type of medicine?

Brief Answer:
EPS could be the reason of this.

Detailed Answer:
Hello thanks for asking

She is on Risperidone most probably. Risperidone is an antipsychotic drug of second generation. The drug in high doses sometimes results in extra pyramidal side effects or EPS. The rigidity like walk and robotic walk are most probably due to EPS due to Risperiodone.

If she has symptoms like increased salivation, slurred voice, difficulty in speaking, drowsiness etc along with then she should be shown to her doctor again. Concomitant use of Trihexyphenidyl should be help her. The drug will reduce the EPS and she will feel better. Talk to her doctor regarding that.

The side effects are not dangerous but should not be ignored. Reduction of dose will also help.

I have had MDD most of my life, I am an almost 60 y.o./ F. Most antiDs have intolerable side effects. SSRIs and others exacerbate my insomnia greatly, even at a low dose. Cymbalta does too. The antiD most effective for sleep for me has been mirtazapine. However it causes OAB (I have to get up to urinate 3-6 times a nite). My Gp added on imapramine to the Mirt to counteract the nocturia but it seems to cause me to awaken and not be able to go back to sleep. One of my primary Sx of depression is lack of appetite. I am already underweight for my frame (126.5 lbs at 5 8 ). Mirtazapine helps me to have an appetite more than anything. If it weren t for the nighttime OAB, it would be the perfect med for me, I also have chronic nerve pain which the Mirt seems to be helping some. My question, do you recommend prescribing a med to counteract nocturia caused by mirtazapine? I do not have urinary frequency during the day, only after going to sleep and thru the night. I had this side effect with Trazadone also. Urinalysis tests show no signs of infection.
