Hello and thanks for using HCM. I have read your question and understand your concerns. If the diagnosis of orthostatic hypotension is right, Ubicar is not listed in drugs that improve it. Ubicar is a combination of coenzyme Q and Carnitin, that are normally produced by body. So, it is a supplement and should be prescribed in cases of low body levels. Treatment about orthostatic hypotension includes home remedies such being well hydrated, avoiding alcohol, exercise, elevating head of the bed and standing up slowly. Drugs used to treat orthostatic hypotension include midodrine, fludrocortisone, NSAID, caffeine. However, Ubicar does not cause any problems if used and could increase energy, so your son can use it, but not to expect any results about orthostatic hypotension. Posture during study should be modified and sitting with body keeping right is the correct position. Hope you found the answer helpful. Take care.
