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.

    What is the medicine Tirosint used for?

    Tirosint is a hormonal replacement therapy for underactive thyroid glands. Thyroid hormones, produced by the thyroid gland, are vital for maintaining normal mental and physical activity and development along with regulating the body’s energy and metabolism. In children, it is essential for the normal mental and physical growth of the child. When low thyroid hormones (hypothyroidism) are produced, naturally or due to some injury (radiation or medication) or if the gland is removed surgically, Tirosint therapy becomes vital to maintain the mental and physical health of the patient.

    In addition, Tirosint is also used in the treatment of other thyroid disorders like different types of goiters (enlargement of the thyroid gland due to hormone imbalances) and thyroid cancers.

    Tirosint medication can be purchased from Canada Pharmacy. Furthermore, Canada Pharmacy also offers Tirosint coupons to give you the best price.


    Tirosint should be strictly followed as directed by your physician. The dose is dependent on the age, body weight, cardiovascular status, medical condition, and any prior medication being taken by the patient. It is best to take Tirosint on an empty stomach at least 30 minutes before breakfast. It should be swallowed whole and rapidly as it may dissolve very quickly and swell in your throat.

    The usual dosage for adults is 1.6mcg/kg body weight. The dose may be adjusted by 12.5 to Tirosint 25mcg increments every 4 to 6 weeks till patient becomes euthyroid. For pediatric (above 6 years) patients, the dose varies between 1.6-5mcg/kg/day, according to age and weight of the child.
