Read the Patient Information and User Manual that comes with D’OXYVA before you start taking it and each time you get a refill. There may be new information. This leaflet does not replace talking with your doctor about your condition or treatment.

If you have any questions about D’OXYVA, ask your doctor or pharmacist.

What is D’OXYVA?

D’OXYVA is a prescription medicine for medical conditions. It can also be obtained over the counter for nonmedical purposes via this website and other authorized resellers. D’OXYVA improves circulation, specifically microcirculation of your blood. This process unique to D’OXYVA triggers protective physiological functions in the body: vasodilation and vasoconstrictions in your vessels, catalyzing vessel structure growth (angiogenesis), autoregulation of local blood supply in tissues and organs, neuroreceptor signaling in the brain, and blood pH balance, amongst other critical functions. D’OXYVA is for adults and children over 10 whose circulation and oxygen levels are low and cannot improve enough with exercise and a low-fat diet alone.

D’OXYVA can lower the risk for chronic wounds, diabetes, rheumatoid arthritis, respiratory complications such as chronic obstructive pulmonary disease (COPD), heart attack, stroke, certain types of heart surgery, and chest, back, and neuropathy pain in patients who have heart disease or risk factors for heart disease such as:

  • age, smoking, high blood pressure, low HDL-C, heart disease.

D’OXYVA can lower the risk for heart attack or stroke in patients with diabetes and risk factors such as:

  • eye problems, kidney problems, smoking, or high blood pressure.

D’OXYVA starts to work in about 2 weeks.

What is Microcirculation?

Recognition of the importance of proper microcirculatory function has been growing rapidly in medical research in recent years. The fact is that microcirculation in the capillaries is the most important system in the body. Capillaries facilitate exchange of nutrients, gases such as oxygen and carbon dioxide, waste, small proteins, and hormones between the blood and body cells. Capillaries connect the entire body and every organ, with an estimated average length of about 50,000 miles. The microcirculatory system helps the structure and function of connective tissue and helps clear congestion of lymph, skin, and other vital tissues. It is the natural cleanser of the body because waste removal is one of the most important aspects of healthy microvascular function.

Who Should Not Take D’OXYVA?

Do not take D’OXYVA if you:

  • are pregnant, think you might be pregnant, or are planning to become pregnant. D’OXYVA has never been reported or tested to cause harm to a pregnant woman or an unborn baby. U.S. FDA regulatory compliance requires that you are notified of any potential risks. If you get pregnant, stop taking D’OXYVA and call your doctor right away.


  • are allergic to D’OXYVA or any of its ingredients. The active ingredient is purified carbon dioxide.

D’OXYVA has not been studied in children under 10 years of age.


Before You Start D’OXYVA

Tell your doctor if you:

  • have muscle aches or weakness
  • drink more than 2 glasses of alcohol daily
  • have diabetes
  • have a thyroid problem
  • have kidney problems

How should I take D’OXYVA?

    • Take D’OXYVA exactly as prescribed by your doctor. Do not change your dose or stop D’OXYVA without talking to your doctor. Your doctor may do blood and noninvasive diagnostics tests to check your microcirculation (skin perfusion pressure), blood pressure, blood glucose, oxygen (SpO2), and cholesterol levels during your treatment with D’OXYVA. Your dose of D’OXYVA may be changed based on these test results.
    • Take D’OXYVA each day at about the same time. D’OXYVA can be taken with or without food.
    • If you miss a dose of D’OXYVA, take it as soon as you remember. If you miss taking D’OXYVA, wait and take the next dose at your regular time. You can take 2 doses of D’OXYVA at the same time or up to 4 doses per day. Clinical studies and users reported no additional benefits by taking more than 5 doses per day.

    • D’OXYVA has never been reported to cause overdosing, however, call your doctor or Poison Control Center right away or go to the nearest emergency room if you experience lightheadedness or any problems breathing.

What Should I Avoid While Taking D’OXYVA?

    • Talk to your doctor before you start any new medicines. This includes prescription and nonprescription medicines, vitamins, and herbal supplements. D’OXYVA and certain other medicines can interact, causing positive side effects; however, on rare occasions, it might potentially cause some negative side effects, such as lightheadedness.

    • Never inhale D’OXYVA or carbon dioxide directly from the pressurized mini cylinder.

What are the Possible Side Effects of D’OXYVA?

D’OXYVA has never been reported to cause any serious side effects. Mild side effects, such as lightheadedness, have occurred in only a small number of people. Your doctor can monitor you for these side effects. They usually go away after a few applications or if D’OXYVA is stopped.

Call your doctor right away if you experience:

    • muscle problems such as weakness, tenderness, or pain that happen without good reason, especially if you also have a fever or feel more tired than usual. This may be an early sign of a rare muscle problem.
    • muscle problems that do not go away, even after your doctor has advised you to stop taking D’OXYVA. Your doctor may do further tests to diagnose the cause of your muscle problems.
    • allergic reactions including swelling of the face, lips, tongue, and/or throat that may cause difficulty breathing or swallowing, which may require treatment right away.
    • nausea and vomiting.
    • passing brown or dark-colored urine.
    • more fatigue than usual
    • yellowing of the skin or whites of your eyes.
    • stomach pain.

    • allergic skin reactions.

In clinical studies, patients reported no adverse side effects while taking D’OXYVA.

Talk to your doctor or pharmacist if you have side effects that bother you or that will not go away.

These are not all the side effects of D’OXYVA. Ask your doctor or pharmacist for a complete list.
