There might be increased drowsiness and impairment of attention for an hour

Detailed Answer:
Hi XXXXXXX park,
Thanks for writing in to us.

I have read through your query in details.
Review of medical literature shows that taking melatonin and klonopin at the same time might result in a transient enhancement of sedation and impairment of memory, coordination, and attention for about an hour after taking the medications.

This is classified as a minor drug interaction and will not affect you seriously.

Please avoid doing activities which require a high level of alertness like driving, swimming, cooking or operating heavy machinery to avoid any accidents.

In a few hours you should be back to normal. Please do not worry.

Hope this answers your question. Please feel free to correct any oversight in my interpretation of your problems and discuss them in detail as per your requirements.

Hope your query is answered.
Do write back if you have any doubts.

Regards,
Dr.Vivek
