Detailed Answer:
Hi dear user
I have gone through your question.
I can understand your concern.

A fine needle biopsy of the thyroid, also called a needle aspiration, involves removing some cells—in a less invasive procedure involving a hollow needle—from a suspicious area of the gland and examining them under a microscope to determine a diagnosis.

This procedure requires little to no special preparation. You must tell your doctor if you are taking medications, such as aspirin or blood thinners.

Klonopin (clonazepam) belongs to a class of drugs known as benzodiazepines.
This drug is used alone or along with other medications to treat convulsive disorders such as epilepsy, but it is also prescribed for panic disorder (unexpected attacks of overwhelming panic accompanied by fear of recurrence).

You should not take clonazepam if you have:
-narrow-angle glaucoma;
-severe liver disease; or
-a history of allergic reaction to any benzodiazepine.

My answer is:Yes ,you can take 1 Tb of Clonazepam to manage your anxiety before the biopsy procedure(only this time and if you don't have contraindications).

Be careful,do not use this medicine in larger or smaller amounts or for longer than recommended because this drug may be habit-forming and misuse of habit-forming medicine can cause addiction, overdose, or death.

So if you need to use it for longer,do not take this medicine improperly or without a prescription.Clonazepam should be taken exactly as prescribed by your doctor.

Hope I have answered your question. If you have any further questions I will be happy to help.
Thank you for using HCM.
Wish you good health.
