Farxiga is an oral antihyperglycemic agent. Its active ingredient is called Dapagliflozin. You can now get a prescription to buy Farxiga online. Read on to find out more, including Farxiga uses, dosage and administration, benefits, and side effects. 

What are the uses of Farxiga?

Adults 18 years and older with type 2 diabetes mellitus, chronic kidney disease, and heart failure may benefit from taking Farxiga. 

• Type 2 diabetes ⁠
  In cases where exercise and diet alone aren’t enough to improve glycemic control, especially for people intolerant to metformin, doctors may recommend taking Farxiga. Doctors may also prescribe Farxiga with other anti-diabetic medications. 
• Heart failure ⁠
  Farxiga helps reduce risks of cardiovascular deaths in patients with symptoms of reduced ejection fraction. Ejection fraction is the measure of how adequately the heart pumps blood.
• Chronic kidney disease ⁠
  Farxiga also helps reduce hospitalization and death in patients suffering from reduced kidney function. 

How does Farxiga work? 

Dapagliflozin, the active component of Farxiga, works by allowing the kidneys to transfer more sugar into the urine, thus lowering blood sugar levels.

Lowering blood sugar this way also aids heart and kidney function. The action of Dapagliflozin increases the elimination of water and salt through urine. Thus, it lowers the overall volume of blood, making it easier for the heart to pump blood. Therefore, the medication benefits heart failure and chronic kidney disease patients.

How is Farxiga administered?

If your doctor decides to treat you with Farxiga, you  may be able to buy Farxiga online with a doctor's prescription. You cannot purchase Farxiga over the counter. It is available as 5mg and 10mg tablets, taken by mouth.

In most cases, doctors advise:

• Type 2 diabetes patients to take 10mg once daily.
• They may reduce the dose to 5mg for type 2 diabetics using insulin. Lowering the doses helps prevent hypoglycemia or low blood sugar.
• Specialists also advise taking Farxiga at the exact time each day, before or after meals.
• The dose that the doctor prescribes may differ depending on your health condition, body weight, and other medications you take.
• Stick to your doctor’s prescribed dose (even if it differs from what is mentioned here).
• Store Farxiga safely away from children, moisture, and light.
• Do not share this medicine with anyone, even if they exhibit similar symptoms as you.

Consult your doctor if you have any questions about your Farxiga dose.

What are the side effects of Farxiga?

Some serious Farxiga side effects may include:

• Kidney injury.
• Cancer of the bladder.
• Low blood sugar.
• Reduced blood pressure.
• UTI (urinary tract infections), which very rarely may lead to severe blood infections.
• Diabetic ketoacidosis.

Due to the seriousness of these side effects, you should call your doctor or go to your nearest hospital as soon as possible if you notice any unusual or severe symptoms.

Other likely side effects may include:

• Frequent urination.
• Back pain.
• Constipation.
• Nausea.
• Discomfort during urination.
• Infections such as the flu or yeast infections.
• Pain in feet or hands.
• Higher blood cholesterol levels.
• Increased urine production.

What are the warnings or precautions for Farxiga?

You will need to receive a prescription from your doctor before you buy Farxiga online. Inform them about your current medications, medical conditions, whether you are breastfeeding or pregnant, and any other information concerning your health.

Factors that can influence how you take this medication include:

• Operating machines and driving
  ⁠⁠Farxiga may cause dizziness and make it difficult to operate machinery or drive. You should avoid such tasks until you establish how you react to this drug.
• Breastfeeding ⁠
  It is not safe to use Farxiga while breastfeeding. The active component of Farxiga passes into breast milk and could harm a baby.
• Pregnancy ⁠
  This medicine is not suitable during pregnancy. You should seek your doctor's advice immediately if you get pregnant while taking it. 
• Seniors ⁠
  Seniors might need lower doses of this medicine because they are prone to more side effects.
• Children ⁠
  Children below 18 years old are advised not to use Farxiga. The effectiveness and safety of this medicine for children are unknown.
• Yeast infection ⁠
  ⁠Farxiga increases the amount of glucose in the urine. The high quantity of glucose in the urine increases the risk of urinary tract and genital infections in females and uncircumcised males with a history of yeast infection.
• Kidney function ⁠
  ⁠Using this drug for a prolonged period may result in kidney problems because it increases glucose production in the kidneys.  
• Ketoacidosis ⁠
  Ketoacidosis occurs when the body breaks down fats for energy due to inadequate insulin to use glucose (sugar) in the blood. As a result, ketones build up in the blood and make it acidic. Rarely, Farxiga may cause ketoacidosis. 
• Liver function ⁠
  ⁠People with severely decreased liver function are discouraged from using Farxiga. 
• Glucose control ⁠
  ⁠Blood glucose levels may decline below average in patients who use Farxiga alongside other drugs. When prescribing Farxiga, doctors will always consider the effects of other diabetes medications a patient uses to maintain good glucose control.
• Cholesterol ⁠
  Patients with high cholesterol should tell their doctor before obtaining a Farxiga prescription online. Dapagliflozin may raise LDL (low-density lipoprotein), a type of cholesterol found in the blood.

Who should not take Farxiga?

Anyone with the following conditions should not use this drug:

• Type 1 diabetes.
• Allergy to Dapagliflozin or any other ingredient of Farxiga.
• Anyone undergoing dialysis for end-stage kidney disease or severely reduced kidney function.

Is Farxiga FDA approved?

Yes, the FDA (Food and Drug Administration) approved the use of Dapagliflozin. The Farxiga drug class is SGLT2 (sodium-glucose co-transporter 2) inhibitor.[1]

The FDA carried out studies to establish Dapagliflozin's safety and effectiveness. Based on the results:

• In January 2014: Farxiga was first approved for patients with type 2 diabetes.
• Farxiga was approved in October 2019 to lower hospitalization risk in patients with type 2 diabetes and advanced cardiovascular disease.
• Farxiga was approved in May 2020 to minimize the risk of hospitalization and cardiovascular death for adult heart failure patients who have reduced ejection fraction and do not have type 2 diabetes.
• Farxiga was approved in April 2021 for adult chronic kidney disease patients at risk of progression.

The benefits the studies included:

• Heart failure ⁠
  ⁠Farxiga effectively helped reduce the risk of hospitalization, death, and urgent medical calls related to heart failure. The study included 4,744 adult heart failure patients having lowered ejection fractions. Patients used both Farxiga and placebo with their regular heart failure therapy.The rate of critical medical calls, hospitalization, and death per 100 patient-years in the Farxiga faction was 11.6 compared with the placebo group's 15.6; the risk was 26% less with Farxiga than placebo.
  
• Chronic kidney disorder
  ⁠⁠Based on a survey that encompassed 4,304 patients, Farxiga effectively helped treat chronic kidney disease.[2] The proportion of patients that suffered death, severe kidney disease, or reduced kidney function was 9.2% for patients who used Farxiga with their other medication. The rate was 14.5% in the placebo group; consequently, Farxiga reduced the risk by 39% more than the placebo.
  
• Diabetes ⁠
  Farxiga proved effective in various analyses in type 2 diabetes patients.[3] The HbA1c (glycosylated hemoglobin) level was the primary measure of effectiveness. HbAc1 indicates how well blood glucose is controlled over 3-6 months.

In two surveys of 840 adults with type 2 diabetes, Farxiga reduced HbA1c values by 0.66 percent more than the placebo treatment within 24 weeks. 

In four different reviews, including 2,370 adults, combining Farxiga with other diabetes pills lowered HbA1c points by 0.54 to 0.68 percent more than combining the treatments with a placebo in 24 weeks. 

Farxiga combined with metformin was equally effective as sulfonylurea medications combined with metformin in research comprising 814 adults with type 2 diabetes. Both variations lessened HbA1c rates by 0.52 percent in 52 weeks. 

Long-term research involving more than 17,000 adult type 2 diabetes patients looked into the impact of Dapagliflozin on cardiovascular disease. The findings indicated that Dapagliflozin worked the same way other diabetic medications work by impeding SGLT2, which improves cardiovascular disease in some patients.

What is the difference between Farxiga and Metformin?

The difference between metformin and Farxiga tablets is in the way they work. Farxiga's function prevents the kidneys from reabsorbing glucose into the bloodstream. Thus, it promotes the loss of sugar through the urine, hence lowering blood sugar levels.

Metformin reduces the amount of glucose made by the liver. It also boosts insulin sensitivity in fat cells, muscles, and the liver. Increased insulin sensitivity lowers blood sugar levels.
