CO₂ injections (carboxytherapy)

  • What it is

    A course of fine subcutaneous injections of sterile medical carbon dioxide (CO₂) gas just beneath the skin around the treated area. Also known as carboxytherapy, it is prescribed and performed by a physician within a balneological programme.

  • Who it's for

    Adults with chronic joint or back pain, degenerative joint disease, post-operative stiffness, or impaired local circulation, seeking a non-surgical, drug-sparing therapy under medical supervision.

  • Expected results

    Improved local blood flow, reduced pain and a greater range of movement, typically building over a course of sessions. Individual response varies and is reviewed by your spa physician.

How CO₂ carboxytherapy works

Carboxytherapy uses sterile medical carbon dioxide — the same gas your body produces naturally. Injected in tiny amounts just beneath the skin, the CO₂ briefly lowers local oxygen levels.

Your body responds by widening nearby small blood vessels, which increases blood flow, oxygen delivery and drainage in the treated tissue. Better local circulation supports the body's own anti-inflammatory and pain-relieving processes.

  1. Consultation & marking

    Duration:10 min

    Your resident spa physician confirms the treatment is suitable, reviews your health history and marks the injection sites around the affected joint or paravertebral area.

  2. The injections

    Duration:15 min

    A very fine needle delivers small, measured doses of warmed medical CO₂ just under the skin. Most guests feel only brief pressure or tingling as the gas disperses.

  3. Short rest & check

    Duration:5 min

    You rest briefly while the gas is absorbed and circulation normalises; the physician checks the treated area before you leave.

  4. Across your stay

    Duration:repeat

    Sessions are repeated every few days so the circulatory benefit builds over the course of your programme.

A typical course is 8–10 sessions across a 2–3 week supervised stay, spaced every 2–3 days.

Frequently asked

CO₂ carboxytherapy — your questions answered

Answers to the questions guests ask most before booking a carboxytherapy programme.

About the treatment

  • Most guests feel only brief pressure, warmth or tingling as the gas disperses under the skin. A very fine needle is used and each injection takes only seconds.

  • A typical course is 8–10 sessions spread over a 2–3 week stay, but your spa physician sets the exact number after assessing your condition.

  • Carboxytherapy delivers CO₂ by subcutaneous injection for a targeted, local effect. A dry CO₂ gas bath envelops the body in warmed gas, and naturally carbonated mineral baths deliver CO₂ through the skin while you bathe. Your physician advises which suits your diagnosis.

Your stay

  • No referral is required for a self-pay medical stay. You are assessed by our resident spa physician on arrival, who confirms suitability and prescribes your programme.

  • CO₂ injections are offered at Mariánské Lázně and Piešťany, among other Ensana medical resorts. Our coordinator can match you to the right destination.
