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.
Nature Throid is a prescription medication that can treat hypothyroidism. Thyroid hormones are a family of hormones that primarily include T3 (triiodothyronine) and T4 (thyroxine). Nature Throid is a type of desiccated thyroid product that contains both T3 and T4.
Desiccated thyroid extract is made by drying and crushing thyroid glands into a powder and then compounding them into a tablet formulation.
Nature Throid works by replacing T3 and T4 in people who do not have enough thyroid hormones circulating in their bloodstream. Thyroid hormones help to regulate growth, temperature, metabolism, and other normal body processes. Nature Throid works to restore the balance of normal thyroid.
The dose of Nature Throid varies greatly based on your thyroid needs. It is normally started at a dose of 30 mg or 32.5 mg taken by mouth once daily on an empty stomach.
The usual dosage ranges from 65 mg to 130 mg once daily but can be as low as 16.25 mg or as high as 325 mg in some people.
Your dose of Nature Throid will be adjusted based on a lab value called TSH, which measures if your thyroid levels are in a normal range or not. Do not take Nature Throid differently than how your doctor prescribes.
The active ingredients in desiccated thyroid are T3 (triiodothyronine) and T4 (thyroxine).
Nature Throid also contains trace amounts of iodine, T1, T2, and calcitonin.
Nature Throid is made from desiccated porcine thyroid, so people with allergies to pork and pork products should not use Nature Throid.
Tell your doctor if you have a history of cardiovascular disease, coronary artery disease, or angina.
Use with caution if you have a history of diabetes.
Use with caution if you have a history of myxedema (severe hypothyroidism).
If you have a history of adrenal insufficiency, symptoms may be worsened by taking thyroid hormone, so use with caution.
When dosed correctly, Nature-Thyroid does not cause any side effects. However, when the dose is too high, it can cause side effects which are similar to hyperthyroidism. Common adverse effects when the dose of Armour Thyroid is too high include:
