In brief: Thyroxine is a type

The thyroid gland secretes two types of hormones: thyroxine (t4) and triiodothyronine (t3), but it produces T4 at much higher levels than t3.
When treating thyroid hormone deficiency, your physician may prescribe levothyroxine (which is oral tablet of t4), liothyronine (oral formulation of t3), or combinations of such, or even dessicated (dried) pig thyroid as replacement therapy.

thyroid hormone is the broader term, with thyroxine a specific type of thyroid hormone.

There are two major active thyroid hormones, T4 and T3. Thyroid hormone replacement medications include thyroxine (T4), triiodothyronine (T3) or dessicated thyroid that contain both T4 and T3 (although not in the same percentages as are found in the human thyroids). The vast majority of people who need thyroid take thyroxine.

In brief: No

The way to think about this is thyroid hormones (plural) and not thyroid hormone (singular).
