Drug Name

Forxiga (Dapagliflozin)

Drug Uses

Forxiga is indicated in adults aged 18 years and older with type 2 diabetes mellitus to improve glycaemic control as:

Monotherapy

When diet and exercise alone do not provide adequate glycaemic control in patients for whom use of metformin is considered inappropriate due to intolerance.

Add-on combination therapy

In combination with other glucose-lowering medicinal products including insulin, when these, together with diet and exercise, do not provide adequate glycaemic control (see sections 4.4, 4.5 and 5.1 for available data on different combinations).

Drug Class and Mechanism 

Dapagliflozin belongs to the class of medications known as oral antihyperglycemic agents. It is used alone and in combination with other medications for the control of blood glucose in people with type 2 diabetes. This medication should be used as part of an overall diabetes management plan that includes a diet and exercise program. Dapagliflozin works by increasing the amount of glucose being removed from the body by the kidneys, which decreases the amount of sugar in the blood.

How to use 

The recommended starting dose for dapagliflozin is 5 mg taken by mouth once a day. Your doctor may adjust the dose up to a maximum 10 mg daily, depending on how effective it is and how well it is tolerated.

Dapagliflozin should be taken at the same time every day. The tablets should be swallowed whole with some fluid and may be taken with food or on an empty stomach.
