Where Can I Get
Desiccated Thyroid Hormone?

Thyroid UK is frequently contacted by patients who do not realise that natural desiccated thyroid hormone (NDT) - 'Armour', manufactured by Forest Pharmaceuticals, 'Nature-Throid' and 'Westhroid', both manufactured by RLC Labs, and 'Thyroid' manufactured by Erfa Canada Inc. - can be prescribed by their GP on a “named patient” basis.

If you do obtain a prescription for NDT and you find that your normal pharmacy cannot obtain this, it might be a good idea to try another pharmacy.  If you still have problems obtaining NDT the following pharmacies may be able to help:

  • Smartway Pharma

Smartway Pharma stock Armour thyroid and will source other brands of NDT if you require them.

If you have an NHS prescription, simply ask your local pharmacy to contact them and they will inform their wholesaling arm, "Smartway Pharmaceuticals LTD", to supply the pharmacy directly

If you have a private prescription, you need to post the original prescription to them at the address below.
Once the prescription is received they will contact you to let you know that it has been received and inform you of the cost of the prescription.

You can then pay via debit/credit card over the telephone. All prescription orders are dispatched using a next day delivery service.

NB. Because there are some variations in dose and potency between the brands (see table below), changing brand may mean that you need a small adjustment from your previous dose of Desiccated Thyroid. You and your GP should work together to establish the dose of the new medication that works for you.

If you are usually prescribed Armour Thyroid by your GP, you should be aware that if you change to Nature-Throid or Westhroid your prescription must state the tablets as 65mg and not 60mg. If this is not correct on your prescription, your pharmacist will not dispense the medicine.

If your GP changes your prescription, he may also need to write another letter stating that the medicine is for hypothyroidism. Some doctors are now putting “natural desiccated thyroid” on the prescription, which may enable you to obtain any of the brands without keep having to get a letter from your GP.

Your pharmacist can try the following wholesalers for supplies of the various desiccated thyroid preparations:
