What is a Generic Drug?

A generic drug is a copy of the brand-name drug with the same dosage, safety, strength, quality, consumption method, performance, and intended use. Before generics become available on the market, the generic company must prove it has the same active ingredients as the brand-name drug and works in the same way and in the same amount of time in the body.

The only differences between generics and their brand-name counterparts is that generics are less expensive and may look slightly different (eg. different shape or color), as trademarks laws prevent a generic from looking exactly like the brand-name drug.

Generics are less expensive because generic manufacturers don't have to invest large sums of money to develop a drug. When the brand-name patent expires, generic companies can manufacture a copy of the brand-name and sell it at a substantial discount.


Chemical Name THYROID (THYE-roid)

Armour thyroid reverses the symptoms of hypothyroidism, a condition where the thyroid gland does not produce enough thyroid hormone. Without thyroid hormone, the body cannot function properly, resulting in poor growth, slow speech, lack of energy, weight gain, hair loss, dry thick skin, and increased sensitivity to cold. Thyroid is also used to treat goiter (enlarged thyroid gland).

Before you start taking THYROID, inform your doctor if you are planning to have medical and/or dental treatments, emergency care or surgery. It is vital to inform your doctor or dentist that you are taking THYROID.

It is important to check with your doctor or pharmacist before you begin to take any new medications, either prescription or over-the-counter. Caution should be used in the elderly since they may be more sensitive to the effects of this drug.

Also tell your doctor if you are pregnant or breastfeeding.

To make sure you can safely take THYROID, tell your doctor if you have any of these other conditions:

  • heart disease, angina
  • coronary artery disease
  • congestive heart failure
  • any type of diabetes
  • problems with your adrenal gland
Important Safety Information About THYROID:
  • THYROID should be used with caution in patients with angina pectoris or the elderly because there is a greater chance of occult cardiac disease
  • This medication may increase symptoms of diabetes mellitus, diabetes insipidus, or cortical insufficiency
  • Caution should be used in infants where excessive doses of thyroid hormone preparations may produce craniosynostosis

Side Effects

Since THYROID is made to replace thyroid hormones, the most common side effects generally mimic an underactive or overactive thyroid (hypothyroidism or hyperthyroidism, respectively). Adverse reactions other than those indicative of hyperthyroidism, either initially or during the maintenance phase, are rare.

If you experience chest pain, increased pulse rate, palpitations, excessive sweating, heat intolerance, or nervousness, please consult your doctor immediately; your dose may need to be adjusted.

Common side effects may include weight loss, tremors, headache, upset stomach, vomiting, diarrhea, stomach cramps, nervousness, irritability, insomnia, excessive sweating, increased appetite, fever, changes in menstrual cycle and sensitivity to heat.

This is not a complete list of side effects and others may occur. Call your doctor for medical advice about additional side effects or any side effect that bothers you or that do not go away.
