Parkinson's with possible dementia

My father is on a boat load of medications and i am worried that he is being over medicated.
clonazepam, carbidopa, levodopa, requip for his parkinson's as well as potassium pill, furosemide, cholesterol pill, allopuinol, lisiniprol, ecotrin asprin, multi vitamin, and mometasone, furmoterol, albuterol inhalers.
With in the past few days he has been hallucinating severly and my mother does not know what to do.

Hi there. I can understand what you are saying, so many medicines any one will get perturbed. I think your father has parkinson’s disease, he is taking furesemide and potassium( frusemide causes hypokalemia), lisinopril, ecotrin (aspirin) for probably hypertension .allopurinol for gout, cholesterol pill for high cholesterol, mometasone, furmoterol, albuterol inhalers for bronchial asthma. Various psychiatric disturbances may occur during levodopa-carbidopa therapy. Such disturbances include memory loss, anxiety, nervousness, agitation, restlessness, confusion, inability to sleep, nightmares, daytime tiredness, mental depression or euphoria. Consult a neurologist for the symptoms that he is suffering from. Though all drugs appear important for the condition that they are tackling, therapies can be modified to reduce hallucination. Take care.
