### input:
my father is 79 years old and suffering from a shuffling gait and urinary incontinence. he has been put onto syncapone 100 (3 times a day) and duprose (morning only) , roliten 2mg (twice a day) and duprost (morning).in addition he is also taking amlong (morning) and ecospirin 75 (night).we have noted that besides the fact that there is very little improvement, he is extremely drowsy all the time and is ending up sleeping almost 14-15 hours a day! he has also become a bit of a recluse and not taking interest in almost anything.i wish to know whether these symptoms are to be expected and whether there is some risk that he is being overdosed? if we decide to reduce syncapone to see how his condition alters -is there any risk?

Hello, It is not surprising that your father is having these Chat Doctor.  Typically, a medication such as Singapore is already mixed in proper proportions with the elemental ingredients for adequate dosing to take place.  However, it just may be that the 100 mg. Dose 3x/day is too much for his body.  Check with his doctor before making any changes, but they may authorize trying him on a lower schedule of 1-2x/day to see if he is less fatigued.  Of course, if he is not responding adequately to the medication then, that is another problem, and you should report this to the doctor as the diagnosis may have to be rethought, or another agent may have to be tried.  Always check with the primary prescriber before making any changes to a patients' medication dosage or frequency of administration. Hope I have answered your query. Let me know if I can assist you further. Take care
