Methylene Blue IV Therapy, Oklahoma City, OK

By Venturis Clinic, Oklahoma City · Updated November 2026

Methylene blue IV therapy is a slow infusion of a low dose of methylene blue, a medicine that has been used in hospitals for more than a century and that interacts with the energy-producing machinery of cells. At Venturis Clinic in Oklahoma City, it is offered only after a Good Faith Exam that includes G6PD testing and a careful medication review, because methylene blue can interact dangerously with some common antidepressants. Infusions are performed by licensed medical staff under our medical director and given by our nurses.

People usually ask about methylene blue IV for fatigue, brain fog or low energy, often during a long recovery from illness or a demanding period. This page explains how it is thought to work, who should not have it, what a visit looks like, the risks and what the research does and does not show.

What methylene blue is

Methylene blue is a blue dye and medication. In the United States, an injectable form is FDA-approved for one use: treating acquired methemoglobinemia, a condition in which blood cannot carry oxygen properly. Hospitals also use it in surgery and diagnostic procedures. Its use for energy, mental clarity or general wellness is off-label, meaning it has not been approved by the FDA for those purposes.

How methylene blue is thought to work

Inside each cell, mitochondria make energy by passing electrons along a chain of proteins. In laboratory studies, methylene blue can accept and donate electrons, which may help that chain keep running when parts of it are not working well. It also has antioxidant effects in lab settings, and it acts on certain enzymes in the brain, which is the same property that causes its drug interactions.

These mechanisms are interesting, but most of the evidence comes from cell and animal studies. What they mean for an individual person is not yet clear.

What the research shows

• Approved use: methylene blue is an established treatment for acquired methemoglobinemia, given in a hospital setting.
• Brain and memory: a small randomized study in healthy adults (Rodriguez and colleagues, Radiology, 2016) found that a single low oral dose changed brain activity on functional MRI and was linked to a modest improvement in short-term memory recall. It was a small, short study, not a treatment trial.
• Fatigue and long-running illness: interest is growing, including in post-viral fatigue, but published human studies are few, small and short. There are no large trials showing that methylene blue IV improves energy or brain fog.

In plain terms: the reasons for interest are real, the proof for wellness use is limited, and we will tell you that directly at your consult. Methylene blue IV is not a cure for any condition, and responses vary.

Who may consider methylene blue IV

After a Good Faith Exam and screening, our team may discuss methylene blue IV with adults who:

• Have ongoing fatigue or brain fog and have had a basic medical workup
• Are recovering from a long illness, such as long COVID, and want to understand their options
• Are not taking medications that interact with methylene blue
• Have normal G6PD activity and kidney function

Who should not have methylene blue IV

• People taking serotonergic medications. This includes SSRIs, SNRIs, MAO inhibitors, some tricyclic antidepressants, and certain other drugs. In 2011 the FDA warned that methylene blue combined with these drugs can cause serotonin syndrome, which can be life-threatening. Never stop a prescribed medication on your own to qualify.
• G6PD deficiency. Methylene blue can cause red blood cells to break down. We test for G6PD before the first infusion.
• Pregnancy or breastfeeding.
• Significant kidney disease.
• Known allergy to methylene blue or similar dyes.

Bring a complete list of your prescriptions, over-the-counter medicines and supplements to your exam. More on how we screen is on our IV infusion safety and screening page.

What a visit looks like

1. Good Faith Exam and labs. Licensed medical staff review your history and medications and order G6PD testing and any other labs you need. Some of this can start before your visit.
2. Check-in. Vitals are taken and any medication changes since your exam are reviewed.
3. The infusion. A nurse places a small IV, and methylene blue is given slowly in a bag of fluid. Many infusions take about 30 to 60 minutes. A nurse monitors you throughout.
4. Afterward. Vitals are checked again. Most people go about their day. Your follow-up plan is reviewed at each visit rather than set in advance.

Where our IV formulas come from

Our IV formulas are prepared by an FDA-registered 503B outsourcing facility under current Good Manufacturing Practice (cGMP) standards and tested for sterility and potency. Each infusion is ordered after your Good Faith Exam and given by our nurses. Compounded IV formulas are not FDA-approved to diagnose, treat, cure or prevent any disease.

Safety and side effects

• Blue or green urine for a day or two. This is expected and harmless.
• A temporary bluish tint to the lips, tongue or skin
• Mild headache, nausea or dizziness
• A cool feeling, soreness or bruising at the IV site
• Pulse oximeters can read falsely low for a short time after an infusion
• Rare but serious: serotonin syndrome in people on interacting drugs, red blood cell breakdown in G6PD deficiency, and allergic reactions. Screening is how we reduce these risks.

Call the clinic for anything that worries you after an infusion, and call 911 for confusion, a very high fever, muscle rigidity, chest pain or trouble breathing.

Cost

Cost depends on your plan and any required lab work, and is discussed at consult before your first infusion. Methylene blue IV is direct-pay and not covered by insurance.

Methylene blue IV: frequently asked questions

Is methylene blue IV FDA-approved?

Injectable methylene blue is FDA-approved only for treating acquired methemoglobinemia. Using it for energy or brain fog is off-label.

Can I have methylene blue if I take an antidepressant?

Often not. Many antidepressants interact with methylene blue and can cause serotonin syndrome. Our medical staff review every medication before ordering an infusion. Do not stop a prescription without talking to the prescriber.

Why do I need a G6PD test?

People with G6PD deficiency can have red blood cell breakdown after methylene blue. The test is a simple blood draw.

Will my urine turn blue?

Usually yes, blue or green for a day or two. It is expected.

How many infusions do people have?

There is no standard number. Your plan is set after your exam and reassessed as you go, and it may be stopped if it is not helping.

Is oral methylene blue the same?

No. Oral and IV forms differ in dose and how much reaches the blood, and over-the-counter products vary in purity. Ask our team before taking any form on your own.
