Glutathione

What Is Glutathione Used For?

Glutathione is a naturally occurring antioxidant found in every cell of the body. It plays a critical role in protecting cells from oxidative stress, supporting immune function, aiding in detoxification processes, and maintaining overall cellular health. As we age, the body's natural production of glutathione declines, which may contribute to increased oxidative damage, reduced immune function, and visible signs of aging. Supplemental glutathione, delivered through injection, is used to support antioxidant defense, promote healthier-looking skin, assist the body's natural detoxification pathways, and support overall wellness. Some patients also report improvements in energy levels and skin brightness with consistent use.

Who Is Eligible?

Glutathione injections may be prescribed to adults (18 and older) who are interested in antioxidant support, immune function enhancement, or skin health improvement. Your INA provider will review your medical history, current health status, and wellness goals to determine if glutathione therapy is appropriate for you. This treatment is generally well-tolerated but may not be suitable for everyone.

Who Should Not Use Glutathione?

Do not use Glutathione if you have any of the following conditions:

• Known hypersensitivity or allergy to glutathione or any component of the formulation
• Pregnancy (insufficient safety data available for use during pregnancy)
• Breastfeeding (insufficient safety data available for use while nursing)
• Active asthma (inhaled glutathione has been reported to worsen bronchospasm in some individuals; discuss injection route safety with your provider)

Warnings and Precautions

• Glutathione injections should only be administered using sterile technique. If you are performing self-injections at home, follow your provider's instructions carefully regarding injection preparation, site selection, and needle disposal.
• While glutathione is generally well-tolerated, injectable supplements carry inherent risks including infection at the injection site. Watch for signs of redness, warmth, swelling, or discharge at the injection site and report them promptly.
• If you have a history of sulfite sensitivity, inform your provider, as glutathione contains sulfur-based amino acids.
• Long-term safety data for supplemental glutathione injections is limited. Your provider will monitor your response and adjust your treatment plan as needed.
• Glutathione supplements have not been evaluated by the FDA for the treatment, cure, or prevention of any disease.

Common Side Effects

The following side effects are relatively common and are usually mild and temporary. Contact your provider if they persist or become bothersome:

• Mild pain, redness, or swelling at the injection site
• Mild nausea
• Bloating or abdominal discomfort
• Temporary flushing or warmth
• Mild headache

Serious Side Effects

• Severe allergic reaction (anaphylaxis) -- difficulty breathing, throat tightness or swelling, widespread hives, rapid heartbeat, dizziness, or loss of consciousness
• Injection site infection -- increasing redness, warmth, pain, or pus at the injection site, possibly accompanied by fever
• Severe abdominal pain -- persistent or worsening stomach pain, cramping, or vomiting
• Kidney concerns -- changes in urine output, color, or frequency (report to your provider for evaluation)

Drug Interactions

Tell your provider about all medications, supplements, and herbal products you are currently taking. While glutathione has limited known drug interactions, the following considerations apply:

• Chemotherapy drugs -- glutathione may interfere with the effectiveness of certain chemotherapy agents. If you are currently undergoing cancer treatment or have a history of cancer, discuss this with your oncologist before starting glutathione therapy.
• Nitroglycerin -- glutathione may enhance the blood pressure-lowering effects of nitroglycerin
• Other antioxidant supplements -- inform your provider about all supplements you take to avoid excessive antioxidant intake

Before Starting Treatment

Before beginning glutathione therapy, provide your healthcare provider with a complete medical history. This should include any history of allergies (especially to sulfur-containing compounds), asthma, liver disease, kidney disease, or cancer. Inform your provider about all prescription medications, over-the-counter drugs, and dietary supplements you are taking. If you are pregnant, breastfeeding, or planning to become pregnant, discuss this with your provider before starting treatment. Your provider will help you understand what to expect and establish a treatment schedule that aligns with your wellness goals.

How to Use This Medication

Glutathione is typically administered as an intramuscular (IM) or subcutaneous injection. Your provider will determine the appropriate dose and frequency based on your individual goals and health profile. If you are performing self-injections at home, follow the instructions provided by your care team carefully. Use proper sterile technique, including cleaning the injection site with an alcohol swab, using a new sterile needle and syringe each time, and rotating injection sites to prevent irritation. Dispose of used needles and syringes in an appropriate sharps container. Store the medication as directed on the label, typically refrigerated and protected from light. Do not use the medication if it appears discolored, cloudy, or contains particles.

Emergency Information

If you experience signs of a severe allergic reaction (difficulty breathing, throat swelling, widespread hives, rapid heartbeat, or dizziness), call 911 or go to your nearest emergency room immediately. If you notice signs of infection at the injection site (increasing pain, redness, warmth, swelling, or fever), contact your provider promptly.
