I am scheduled to have thyroidectomy and my surgeon prescribed this medication. The pharmacist that dispensed it instructed me to apply it topically to the surgical site. When I read the insert, it said orally. I called the pharmacist back and he told me that it is usually for topical use but it is taken by mouth in preparation for thyroid surgery. I looked at Safecor's website which indicated that it is for topical application. Please advice.
