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.

Product Details
Description
Synthroid (Levothyroxine) is a medication used to treat hypothyroidism. Hypothyroidism occurs when there is too little thyroid hormone in the body, which can cause a variety of symptoms that impact mood, weight, and body temperature.
The body may have too little thyroid for several reasons, including problems with the thyroid gland itself, problems with the pituitary gland -- which send functional signals to the thyroid gland, differences in genetics (congenital), or acquisition with age.
Synthroid is a synthetic version of the thyroid hormone T4. The generic name is levothyroxine. Synthroid replaces T4 and is converted to active thyroid hormone, T3, in the body.
Directions
Synthroid dosages can range from 12.5 to 200 micrograms daily. Some people may require doses above this range.
Synthroid should be taken on an empty stomach, at least 30 minutes before a meal. Synthroid can be taken with water. Take Synthroid in the same manner each day, since food can timing can change how much is absorbed and impact the treatment.
Ingredients
The active ingredient in Synthroid is levothyroxine sodium.
Cautions
Use Synthroid with caution in older adults with underlying cardiovascular disease.
