Welcome to health care magic.
Palido OD is an antipsychotic
medicine that is given to control the abnormal thoughts
Palido causes significant adverse effects in patients.
To control them, parkin is given which is trihexiphenydil, a central antichlinergic.
These medicines can cause episodes of anxiety
and panic attacks that is the main problem in your case so you should slowly taper of these medicines in supervision of a local physician.
You should get revaluation by a local psychatrist. I think it will be better if you get treated for your anxiety and panic attacks by a different group of drugs call benzodiazepines after clinical examination and assessment. Your clinician will be able to judge to decide between the two group of the drug after assessment.
I think the advice will be helpful for you.
