Good morning all,

I was wondering if anyone had experience in the following. Dad was prescribed Haliparadol (apologies for spelling) about 2 years ago to curb over excitement and aggressiveness, this worked well but introduced drug induced Parkinsons (or so we believe) his specialist has now advised that this drug be removed and if neccessary his prescription of chlorpromozine (again apologies ) to be increased. Mum is worried that the removal of Haliparadol will bring back the aggressive outburst, I know it's individual but was just wondering if anyone had any advice on the topic, or previous experience

Many thanks

Sorry Rache, I have no experience of these drugs, or their possible side effects , but am sure someone soon will get back to you with more information.

Take care

Hi Rach,

I don't have any first-hand advice to offer but you might want to take a look at the Alzheimer's Society's fact sheet on drugs to treat behavioural symptoms:

The type of symptoms that you describe (like Parkinsons - often referred to as extrapyramidal side effects) seem to be typical of long term use with certain types of anti-psychotic medication.

It appears that some of these medications (so-called typical anti-psychotics, which Haloperidol is) may be more likely to produce these symptoms compared to others (so-called atypical anti-psychotics).

It could be quite possible that the original triggers behind your father's aggression are no longer there after two years.

Take care,
