Methylene blue is a synthetic compound studied for antioxidant and antimicrobial properties. Drug interaction references such as Drugs.com list a wide range of medications, including SSRIs, SNRIs, MAOIs, opioids, stimulants, and triptans, as having potential interactions with methylene blue, including a risk of serotonin syndrome. This is not medical advice. It is crucial to consult a healthcare provider before use if you are taking any other medications.
Initially invented as a dye in 1876, methylene blue was historically studied as a treatment for malaria in early medical research. Researchers have since investigated its antimicrobial properties in laboratory settings, including against bacteria such as Borrelia and Bartonella, as well as its effects on mitochondrial function. More recently, methylene blue has been the subject of research exploring neuroprotective and mitochondrial effects in preclinical studies. These remain areas of ongoing scientific investigation and are not established or FDA-approved medical uses.
Methylene blue has monoamine oxidase inhibitor (MAOI) activity, which Drugs.com and other drug-interaction references cite as a factor that can increase the risk of serotonin syndrome when combined with other serotonergic drugs such as SSRIs, SNRIs, and tricyclic antidepressants. Serotonin syndrome is described in medical literature as involving symptoms like agitation, confusion, rapid heart rate, and high blood pressure, and in severe cases, can be fatal.
Drugs.com also lists potential interactions between methylene blue and medications such as acetazolamide, antacids, sodium bicarbonate, diuretics, and blood thinners, noting they may alter effectiveness or increase side effects. Even common supplements like St. John's Wort, 5-HTP, and CoQ10 are listed as having potential adverse interactions with methylene blue.
The Herxheimer reaction is an immune response that can occur when large quantities of toxins are released into the body as bacteria or other pathogens die off during antimicrobial treatment. This reaction is characterized by symptoms such as fever, chills, headache, muscle pain, diarrhea, fatigue, and worsening of existing symptoms. It typically occurs within hours to a few days after starting treatment and is often described in conditions like Lyme disease, syphilis, and other infections treated with antibiotics or antimicrobials.
When using an antimicrobial compound such as methylene blue, the rapid die-off of bacteria can lead to a release of endotoxins into the bloodstream. This sudden influx of toxins may trigger an acute inflammatory response from the immune system, which is often referred to as the Herxheimer reaction. While this reaction can be uncomfortable and alarming, it is generally described as a temporary response rather than a dangerous one.
It is crucial to consult a healthcare provider before starting methylene blue, especially if you are taking other medications, to avoid adverse interactions and ensure safe use.

Drugs.com's interaction checker lists SSRIs such as sertraline (Zoloft), fluoxetine (Prozac), and escitalopram (Lexapro) as a major interaction with methylene blue, citing a risk of serotonin syndrome. This is not medical advice. Talk to a healthcare provider before combining methylene blue with any SSRI or SNRI.
Can I take methylene blue with Adderall, Ritalin, or other ADHD stimulant medications?
According to Drugs.com, amphetamine (Adderall) and methylphenidate (Ritalin, Concerta) are both listed as major interactions with methylene blue, citing a risk of dangerously high blood pressure. This is not medical advice. Consult a healthcare provider before combining methylene blue with any stimulant medication.
Is it safe to take methylene blue with opioid pain medications like Vicodin, Percocet, or tramadol?
Drugs.com classifies common opioids, including hydrocodone (Vicodin, Norco), oxycodone (OxyContin, Percocet), and tramadol (Ultram), as major interactions with methylene blue, citing risks including serotonin syndrome and respiratory depression. This is not medical advice. Consult a healthcare provider before combining methylene blue with any opioid medication.
Can I take methylene blue if I'm on an MAOI like Marplan, Parnate, or Emsam?
Drugs.com lists MAOIs such as isocarboxazid (Marplan), tranylcypromine (Parnate), and selegiline (Emsam, Eldepryl) as major interactions with methylene blue, since methylene blue itself has MAOI-like activity. This is not medical advice. Consult a healthcare provider before combining methylene blue with any MAOI.
Does methylene blue interact with Sudafed or other decongestants?
According to Drugs.com, pseudoephedrine (Sudafed) and phenylephrine are both listed as major interactions with methylene blue, citing a risk of hypertensive crisis. This is not medical advice.

Drugs.com classifies triptans such as sumatriptan (Imitrex) and rizatriptan (Maxalt) as major interactions with methylene blue, citing an increased risk of serotonin syndrome. This is not medical advice. Consult a healthcare provider before combining methylene blue with any triptan medication.
Is methylene blue safe with St. John's Wort or other serotonergic supplements?
Drugs.com lists St. John's Wort, L-tryptophan, and 5-HTP as major interactions with methylene blue, citing combined serotonergic effects that may raise the risk of serotonin syndrome.

Can I take methylene blue with psilocybin mushrooms, LSD, MDMA, or other psychedelics?
Psilocybin mushrooms, LSD, MDMA, DMT, ayahuasca, and similar substances are not included in the Drugs.com-based list above. That does not mean the combination is safe. In a 2011 Drug Safety Communication, the FDA warned of serotonin syndrome when methylene blue is given to patients taking serotonergic psychiatric medications, and published research (Ramsay et al., British Journal of Pharmacology, 2007) describes methylene blue as a monoamine oxidase (MAO-A) inhibitor. These substances are described in the medical literature as acting on the serotonin system, and ayahuasca is described as containing MAO inhibitors of its own. Do not use Nutricel methylene blue products with any of these substances. This is not medical advice. Consult a healthcare provider.
