What is a Generic in Canada? Health Canada (the Canadian regulatory board) evaluates every Canadian generic for their safety, effectiveness, and quality. Every generic used in Canada has the same medical ingredients as their brand name counterpart and is considered bioequivalent to the brand name medication. The quality standards for brand name drugs and generic drugs are the same. All of the ingredients, facilities, and manufacturing processes must meet Canadian federal guidelines for Good Manufacturing Practices. In addition, Canadian generic manufacturers must perform 'comparative bioavailability' studies to demonstrate that their generic products deliver the same amount of medicinal ingredient at the same rate as the brand name medication. Nearly 45% of all prescriptions filled in Canada use generic medication and some hospitals exclusively use generic drugs. For more information, please visit

About ERFA Thyroid 60 mg

What is ERFA Thyroid?

ERFA thyroid, which contains desiccated thyroid, is used as thyroid replacement hormone for patients with hypothyroidism and myxedema. Hypothyroidism is ten times more common in women than men and it often occurs between 40-50 years of age, when women are experiencing menopause.

History of thyroid hormone replacement therapy

In 1891 Dr George Redmayne Murray published the first paper on the success of using sheep thyroid extract (injected subcutaneously) and within months, there was evidence that oral formulations were also effective. However, it wasn't until 1927 that the chemical thyroxine was identified as the benefactory compound. In 1950, Hart and Maclagan invested in the use of L-thyroxine. Although L-thyroxine was available since 1930, it had not been widely used due to its high cost (familiar story, different century). Meanwhile, desiccated thyroid was used for many years and was popular until 1970’s where increased evidence of safety, and decreased price, of L-thyroxine made desiccated thyroid fall out of favor of patients and doctors alike.

How do I take ERFA Thyroid?

The exact dose of thyroid hormone should be individualized according to laboratory results and patient feedback. There is a large variability in individual responses and it can take 4 to 6 weeks to reach maximum therapeutic effects. Patients may start at 30 mg -180mg daily and increase their doses to 60mg - 300mg daily.

If you forget a dose of ERFA thyroid, take it as soon as you remember or return to your usual dosing schedule if it’s almost time for your next dose. Do not double dose in the same day.

What's the difference between ERFA Thyroid and Synthroid?

Synthroid, which contains the active ingredient L-thyroxine, and ERFA Thyroid (desiccated Thyroid) are both thyroid replacement therapy that are used to treat hypothyroidism. The key difference between the two medication is that Synthroid is a synthetic version of the chemical T4 (levothyroxine) whereas ERFA thyroid is a natural product made from animal thyroid glands. Because ERFA thyroid comes from an natural source, it contains a mixture of T4 and T3 (triiodothyronine). While studies have shown that levothyroxine is the best therapy for hypothyroidism because it also prevents thyrotoxic levels of T3, some patients are unresponsive to T4 therapy and prefer desiccated thyroid as a more “natural” version of thyroid. In general, 60mg of ERFA thyroid is considered to be equivalent to 100mcg of Synthroid.

What are the common side effects of ERFA Thyroid?

Side effects from ERFA thyroid are usually temporary and will go away as your body adjusts to thyroid therapy. Many side effects can be contributed to either too low, or too high of a dose so it is important to follow up with your doctor regularly when initiating therapy for lab tests and dosage adjustments. Some patients may experience hair loss in the first few months of therapy. If you develop a rash/itching/swelling/allergic reaction, severe dizziness, sensitivity to heat, mental changes, tremor, chest pain, irregular heartbeat, swelling, or seizures, please talk to your doctor immediately.

What foods should I avoid when taking ERFA Thyroid?

ERFA thyroid absorption is decreased when taken with food and generally, it is recommended to take thyroid supplements on an empty stomach. Avoid foods rich in calcium (Greek yogurt, fortified orange juice) within 3 hours of your dose. If you suddenly change from a high-fat to a low-fat diet, or vice-versa, or suddenly change the amount of fiber in your diet, this may also affect ERFA thyroid absorption.

Can I drink alcohol while taking ERFA Thyroid?

While alcohol does not have a direct interaction with ERFA thyroid, alcohol can drastically affect almost all thyroid gland functions. Alcohol can destroy thyroid cells, block its activity, or lower levels of T3 and T4.

What drugs interact with ERFA Thyroid?

ERFA Thyroid interact with several commonly used medication. Below is not a complete list of drug interactions. Please talk with your health care provider individually to assess your list of medication.

ERFA Thyroid interacts with SSRIs (serotonin-reuptake inhibitors) used for depression. Using these medication in combination usually require the dose of ERFA Thyroid to be increased to maintain therapeutic efficacy. PPIs (Proton pump inhibitors) decrease the absorption of ERFA Thyroid. Using TCAs (tricyclic antidepressants) with ERFA Thyroid causes increased potency of both medication. Insulin and hypoglycemic drugs decrease efficacy of ERFA Thyroid. Estrogen, such as the chemicals found in birth control pills, and some cholesterol-lowering drugs can inactivate thyroid hormone. Taking anticoagulants and ERFA Thyroid together may cause anticoagulants to be more potent and increase the risk of bleeding. Antacids should generally be taken 3 to 4 hours after ERFA Thyroid dosing.


Buy ERFA Thyroid from Canada

Desiccated thyroid tablets in USA have had a secretive and mired history. It started in 2009 when Armour Thyroid, one brand of natural desiccated thyroid available in USA, quietly changed how their tablets were manufactured. In hopes of creating a harder tablet that doesn’t crumble, Forest Labs, the manufacturer of Armour Thyroid, increased the amount of cellulose and decreased the amount of sucrose in the tablets. Unknowingly, changing these excipient ingredients caused patients who were previously stable on their thyroid dose to suddenly report that their medication wasn’t working anymore. This started the trend of USA patients looking for their thyroid medication in Canada. The natural desiccated thyroid product, akin to Armour Thyroid, in Canada is called ERFA Thyroid and was not affected by a formulation change.

Can ERFA Thyroid help me lose weight?
Weight gain is a symptom of hypothyroidism. However, despite popular belief, correcting thyroid deficiency with either levothyroxine or ERFA Thyroid does not cause significant weight loss in most patients.
What is in ERFA Thyroid?
Other than the active ingredient, desiccated thyroid, each tablet contains lactose, cornstarch, magnesium stearate, sugar and talc. ERFA thyroid is gluten free.
What animal does the ERFA Thyroid come from?

ERFA Thyroid conversion chart
Please refer to the ERFA Thyroid product monograph for exact instructions. 0.1mg of levothyroxine (i.e.. 100mcg of T4) is equivalent to 1 grain of desiccated thyroid (60mg).
ERFA Thyroid shortage
Pharmacists agree that ERFA Thyroid is among the most frequently unavailable drugs in Canada. The usual reason provided by the manufacturer is that, because desiccated thyroid is made from an animal source, increased demand and difficulty obtaining raw materials leads to frequent drug shortages.
What is the difference between Armour thyroid and ERFA thyroid?
ERFA and Armour thyroid are both natural dessicated thyroid products. The manufacturers are ERFA and Armour respectively. Although ERFA and Armour thyroid are both dessicated thyroid tablets many patients notice different therapeutic results and this is down to the other inactive ingredients of the tablet that make up the drug delivery system. When the formulation of Armour thyroid was changed in 2009 many patients noticed therpeutic differences forrcing them to look North to Canada for their thyroid. ERFA thyroid is considered to be a much more similar formulation to the old formulation of Armour, and as such is one that many patients and doctors prefer.
