Thyroid Powder USP Compounded!

As you may be aware, all forms of the commercially available Thyroid USP product are no longer available; this includes all forms of Armour Thyroid®, Nature-Throid® and Westhroid®. We have been able to source the Pharmaceutical Thyroid USP Powder for compounding to alleviate the market shortage this has caused. We are currently compounding all strengths of the Thyroid USP so that you can continue therapy without interruption.

There is no need to adjust dosage as this is the exact same active ingredient found in the commercially available dosage forms above. Please contact us if we can answer any question that you might have or send us an email to: info@parkrx.com Toll Free 866-551-7195.

• Porcine Thyroid Powder, U.S. Pharmacopeia (USP)

• Porcine Thyroid Powder, U.S. Pharmacopeia (USP)

• Sodium Starch Glycolate(synthetically derived from starch molecule; aids in disintegration in stomach)
• Magnesium Stearate(Derived from a vegetable source like palm oil; lubricating agent for tablet compress).
• Hydroxypropyl Methylcellulose(Plant cellulose base, aka cotton or wood pulp; provides bulk with PEG)
• Stearic Acid(from vegetable source–typically palm oil; holds ingredients together).
• Carnauba Wax(from pores of leaves of Brazilian wax palm tree; provides complete seal of tablet)
• Polyethylene Glycol(PEG)(synthetic; used with Hydroxypropyl Methylcellulose for clear coating)
• Colloidal Silicon Dioxide(from mined ore: natural desiccant to protect from moisture and humidity)
• Lactose Monohydrate(traceable amount as part of desiccated thyroid powder USP)

ARMOUR (Armour was reformulated in 2009, supposedly decreasing the amount of dextrose and increasing cellulose. Unfortunately, numerous patients report problems with it. Many are switching to Naturethroid). It’s made by Forest Pharmaceuticals. It is made in the following strengths: 1/4, 1/2, 1, 2, 3, 4 and 5 grain tablets.  The 3 and 5 grain tabs are scored., One grain is 60 mg and contains 38 mcg. of T4 and 9 mcg. of T3, plus unmeasured amounts of T2, T1 and calcitonin. The latter three are not removed, as rumor occasionally states.  Each tablet contains:

• Porcine Thyroid Powder, U.S. Pharmacopeia
• Dextrose, Anhydrous (anhydrous means any water has been removed and makes the tablet more stable)
• Microcrystalline Cellulose, NF
• Sodium Starch Glycolate, NF
• Calcium Stearate NF (stabilizer and lubricant)
• Opadry White (Titanium dioxide used as whitening agent, but also contains trace amounts of PEG (polyethylene glycol), Polysorbate 80, and Hydroxypropyl Methycellulose. See below.) Armour Thyroid does not contain gluten or lactose. But neither do Naturethroid or Westhroid.
