Question: Hello, our 12 year old son is 1 year out from a gunshot wound to the head resulting in a full frontal lobotomy. He is currently taking Amantadine 15ml x2, Baclofen 4ml x4, Gabapentin 12ml x3, Kepra 5ml x2, Lanzoprazole 10ml x1, Phenobarbital 11.5ml x2 and Diazapam 7.5ml x 3 times per day + 5ml PRN as needed and Simethecone .6ml x4. We would like to replace the diazapam for "tone" with dantrolene as the diazapam is only sedating him for the increasing muscle stiffness our son is experiencing. I have read the contraindictions about dantralene but several of our friends from the brain injury alliance recommend it highly from their experience. What is your opinion?

Brief Answer:
to monitor for interactions

Detailed Answer:
Thanks for your query. I understand your concerns.

Dantrolene is a good drug for spasticity but it can have significant interactions with three of the drugs your son is currently taking, namely, baclofen, gabapentin and phenobarbital. So, we may need to start it at the lowest dose and gradually increase if there are no features of drug interactions, particularly sedation and muscle weakness.

Apart from this, periodic liver function tests are required to check for liver toxicity which may be a serious adverse effect of dantrolene.

Hope this helps.

I am 60 years old & have been on plavix 75, and an aspirin for 2 years since my mini strokes. I was previously on caduet 5/40 for about 8 years prior to the mini strokes. I have recently developed muscle weakness in my legs to the point of almost collapsing walking from the car, grocery shopping, etc. I do water aerobics twice a week, and zumba once a week. Is there anything more I can do to re-instate my muscle strength?

My mom has dermatomyositis. She has had treatment over the years with steroids, and methotrexate. In the last year her condition is deteriorating with increased muscle weakness and diminished pulmonary capacity due to weakness of the respiratory muscles. She has had three months of IVIG treatment recently with no improvement and has developed a deep vein thrombosis in the left leg. The doctors want to discontinue IVIG and start her on rituximab infusions. Is this medication safe and how effective has it been in treating patients with RA and dermatomyositis?

I have difficulty getting back to sleep when I wake up at night, pains/aches in joints and hands, mood swings, forgetfullness, body odour problems. When I twist the upper part of my body, where my thyroid is it feels like something is grinding and it blocks my airways a bit making it difficult to breathe. I take no medications apart from a ventolin inhaler. I have been diagnosed with adhd, tourette syndrome & depression. It really appears to me to be a thyroid problem but the tests have always been negative
