Hello and thanks for your query.
I shall make an effort to provide you with good professional recommendations specific to your questions.Cold
hands and feet are due to lowered blood pressure as the noted side effect of Lisdexamphetamine. Probably, try to elevate the leg end of bed with pillows on the bed lying down for a while when these trouble you.
Let me know if I have missed out any other concern in your question.
Yet again, I duly appreciate your query to me, I do hope that you have found something useful to help you and I shall be glad to answer any further apprehensions.
Dr Sujeet N Charugulla,
