What is Xiduo?

Xigduo XR is an extended-release oral diabetes drug containing a combination of dapagliflozin propaned and metformin. It’s also known as dapagliflozin propaned-metformin, dapagliflozin propanediol-metformin, dapagliflozin-metformin HCl, or simply dapagliflozin-metformin. These ingredients work together to control blood sugar in patients with type 2 diabetes. Xigduo does not treat type 1 diabetes.

Dapagliflozin Propanediol

Dapagliflozin is categorized as a sodium-glucose cotransporter 2 (SGLT2) inhibitor, which means it prevents your kidneys from absorbing as much glucose from your body. Typically, the kidneys filter the blood, removing waste products and sending other compounds (such as glucose) back into circulation. Glucose and sodium are transported together into a portion of the kidneys that handles this waste filtration and reabsorption. Glucose usually diffuses back into the bloodstream through kidney capillaries. This reabsorbed glucose is included in blood glucose levels.

An SGLT2 such as dapagliflozin prevents sodium and glucose from being transported into the region of the kidneys that manages reabsorption. This prevents glucose from re-entering the bloodstream. Instead, the glucose is treated as a waste product. It leaves the body in urine. Dapagliflozin reduces blood glucose by increasing glycosuria, or the amount of glucose in the blood. Glycosuria is often a symptom of untreated type 2 diabetes. However, it is also a strategy for reducing blood sugar in patients under a doctor’s care. Dapagliflozin is also sold as the brand name drug Farxiga.

Metformin

Metformin is the first-line treatment for patients with type 2 diabetes because it encourages increased insulin responsivity. Insulin is a hormone the liver normally releases when the blood contains high levels of glucose. Insulin acts on cells throughout the body, instructing them to absorb glucose and either use it for immediate energy to to store it for use later. However, type 2 diabetes is characterized by insulin resistance. Patients with type 2 diabetes do not exhibit the standard response to insulin. Their cells are less likely to absorb glucose even in the presence of insulin.

Metformin treats high blood glucose by reducing the amount of glucose made in the liver, reducing the amount of sugar absorbed from food during digestion, and reducing the amount of stored energy that’s transformed into glucose. Metformin is also known by the brand names Glucophage, Fortamet, and Riomet.

Metformin also comes in a generic tablets.

How Does Xigduo Work?

By combining dapagliflozin propanediol and metformin, Xigduo lowers blood sugar through several avenues. It prevents the kidneys from reabsorbing glucose, allowing the glucose to instead leave the body in urine. It reduces the amount of glucose absorbed during digestion. It also prevents the liver from making as much glucose and from triggering glucose to be produced from stored energy.

Xigduo Precautions and Warnings

Don’t use Xigduo if you’re allergic to dapagliflozin, metformin, or any of the medicine’s inactive ingredients. Tell your medical team about all your allergies and any negative reactions to other diabetes medicines to make sure Xigduo is a good fit for you.

It can be hard to control your blood sugar when you are ill, dehydrated, recovering from injury or illness, or dealing with other physical stress. Don’t use heavy machinery or drive until you know how Xigduo will affect you. Consider carrying glucose tablets or gels in case of dangerously low blood sugar. Your doctor may recommend monitoring your glucose levels while taking Xigduo.

Xigduo can impact the menstrual cycle including making it more likely to conceive. This medication may not be safe during pregnancy or breastfeeding. Talk with your doctors, including your child’s pediatrician if relevant, to determine the best way to manage your blood sugar if you’re pregnant, nursing, or trying to get pregnant.

Don’t use Xigduo if you have type 1 diabetes. Type 1 and type 2 diabetes are different conditions and Xigduo will not treat type 1 diabetes. In fact, it could make type 1 diabetes symptoms worse.

Xigduo changes how your liver and kidneys work. These organs play important roles in your metabolism, immune system, and waste filtration. Xigduo can therefore make other conditions worse. Tell your doctor if you have current or previous problems with any of these conditions:

  • Liver, kidney, or pancreatic disease
  • Genital or anal infections

Lactic Acidosis

Some of these symptoms can be caused by lactic acidosis, a rare but serious condition that can cause heart or liver failure. Call your doctor immediately if you experience digestive trouble that goes away and then returns since this could be a sign of lactic acidosis. Other lactic acidosis symptoms include:

  • Extreme tiredness or fatigue
  • Blue skin, lips, or nails
