What Severity, Likelihood & Evidence Mean

Severity — How Serious It Can Be

  • Major. Clinically significant; generally best avoided, or used only under direct professional supervision.
  • Moderate. May need monitoring, a dose adjustment, or separating the times you take each one.
  • Minor. Generally not clinically significant, but still worth noting and mentioning to your pharmacist.
  • No known interaction. Checked against our sources with nothing documented — not the same as proven safety.

Likelihood — How Well It’s Documented

  • Likely. Well-controlled human studies have demonstrated the likely existence of this interaction
  • Probable. Interaction has not been documented in well-controlled studies, however, the interaction has been demonstrated in some small human studies or in controlled animal studies in conjunction with multiple case reports.
  • Possible. Interaction has been documented in animal or in lab research, or the interaction has been documented in humans but is limited to case reports or conflicting clinical research exists
  • Unlikely. Interaction has been demonstrated in animal or in lab research but has been shown not to occur in humans.

Where This Data Comes From

  • Interaction records are evidence-graded and sourced from the Natural Medicines database (TRC Healthcare), the same reference used by pharmacists and hospitals.

The bottom line

Idebenone is a synthetic, lab-made antioxidant related to coenzyme Q10. It has been studied mostly as a prescription drug for certain rare mitochondrial and neurological conditions, and is also used in some skin-care products, but evidence for over-the-counter supplement use is limited. Talk with your pharmacist or doctor before using it.

Overview

Idebenone is a synthetic (man-made) compound. It is not an herb and does not come from a plant. It was created in a laboratory to be similar to coenzyme Q10 (CoQ10), a substance your body makes that helps cells produce energy and acts as an antioxidant.

In some countries, idebenone has been studied and used as a prescription medicine for certain rare inherited conditions that affect the eyes, brain, or muscles. In other places it is sold as a dietary supplement or used as an ingredient in anti-aging skin creams and serums.

People most often take idebenone hoping to support brain function, energy, and overall antioxidant protection, or apply it on the skin for anti-aging effects.

How it works

Idebenone is designed to act like coenzyme Q10. Inside cells, structures called mitochondria work like tiny power plants that make energy. Idebenone is thought to help cells produce energy and to work as an antioxidant, meaning it may protect cells from a type of damage called oxidative stress.

Because it is more easily absorbed and may dissolve differently than CoQ10, researchers have studied whether it can reach tissues that need protection. However, much of what we know about how idebenone works comes from laboratory and animal research, and the effects in healthy people taking supplements are not fully understood.

Natural Medicines’ 7-point scale. We show each rating’s label word-for-word.

1EffectiveStrong, consistent evidence it works.
2Likely EffectiveGood evidence, though not yet conclusive.
3Possibly EffectiveSome evidence suggests a benefit.
4Possibly IneffectiveSome evidence it may not help.
5Likely IneffectiveFairly strong evidence it doesn’t help.
6IneffectiveStrong evidence it doesn’t work.
7Insufficient Reliable Evidence to RateToo little research to say either way.
Possibly Effective Alzheimer disease
Rating & evidence shown verbatim from Natural Medicines

There is some evidence that taking idebenone 90-120 mg three times daily orally for 6 months slows cognitive function decline in patients with Alzheimer disease when compared with placebo. Idebenone appears most effective in patients with moderately severe Alzheimer disease, based on standard Alzheimer disease rating scales.

Possibly Effective Leber hereditary optic neuropathy
Rating & evidence shown verbatim from Natural Medicines

Small and low-quality research shows that taking oral idebenone 900 mg orally daily moderately improves or stabilizes visual acuity in patients with early Leber hereditary optic neuropathy (LHON). The efficacy of initiating treatment in patients with a long history of LHON is unknown.

Possibly Effective Muscular dystrophy
Rating & evidence shown verbatim from Natural Medicines

Idebenone is associated with a small improvement in respiratory function in adolescents and teens with Duchenne muscular dystrophy (DMD) who are not taking glucocorticoids.

Possibly Ineffective Friedreich ataxia
Rating & evidence shown verbatim from Natural Medicines

While some preliminary research shows conflicting results, higher quality clinical research shows that idebenone does not help control cardiac hypertrophy associated with Friedreich ataxia. Most clinical research also shows that taking idebenone does not treat or slow the progression of ataxia in children and young adults with this condition. Although some preliminary clinical research suggests that idebenone might improve neurological symptoms when taken in higher doses or for longer durations, current clinical management guidelines for Friedreich ataxia state that idebenone does not improve cardiac or neurological status in patients with Friedreich ataxia when used over an extended time period.

Also studied for 4 conditions — evidence insufficient to rate
Insufficient Reliable Evidence To Rate Depression
Rating & evidence shown verbatim from Natural Medicines

Preliminary clinical research in adults aged 55-75 years with post-stroke depression suggests that adding idebenone 30 mg three times daily to paroxetine treatment for 12 weeks increases the effectiveness (cured or improved) rate, as measured by the Hamilton Rating Scale for Depression, from 62% with paroxetine alone to 82% with the combination.

Sources Ref 112059
Insufficient Reliable Evidence To Rate Mitochondrial myopathies
Rating & evidence shown verbatim from Natural Medicines

There is preliminary clinical research that suggests idebenone given orally might reduce symptoms in patients with mitochondrial dysfunction associated with the syndrome of mitochondrial encephalopathy with lactic acidosis and stroke-like episodes.

Insufficient Reliable Evidence To Rate Multiple sclerosis (MS)
Rating & evidence shown verbatim from Natural Medicines

Preliminary clinical research in adults with primary progressive MS shows that taking a specific idebenone product (Santhera Pharmaceuticals) 750 mg three times daily for 2 years does not slow the progression of disability or attenuate central nervous system tissue destruction when compared with placebo.

Sources Ref 105707
Insufficient Reliable Evidence To Rate Wrinkled skin
Rating & evidence shown verbatim from Natural Medicines

Preliminary clinical research shows that topical application of a lotion containing 0.5% or 1% idebenone twice daily for 6 weeks reduces signs of photoaging when compared to baseline. Skin roughness and drying is reduced by up to 26%, and fine lines and wrinkles by up to 29%, while skin hydration is increased by 37%. Skin pigmentation is also improved.

Safety & precautions

In clinical studies, idebenone has generally been tolerated by many people, but the long-term safety of taking it as a supplement is not well established. Quality and strength of over-the-counter products can vary widely.

People with existing medical conditions, especially heart, liver, or neurological conditions, should talk with a doctor before using idebenone. Children should only use it under medical supervision.

Pregnancy and breastfeeding: There is not enough reliable safety information for these situations. To be safe, avoid idebenone if you are pregnant, trying to become pregnant, or breastfeeding unless your doctor specifically advises otherwise.

Always tell your pharmacist or doctor about any supplements you take, especially before surgery or if you start a new medication.

Side effects

Reported side effects are usually mild and may include stomach upset, nausea, diarrhea, headache, or dizziness. Some people may notice a reddish or orange color to their urine, which is generally harmless.

Topical (skin) products may cause redness, itching, or irritation in sensitive people. Stop use and check with a professional if you have a reaction.

Serious side effects appear to be uncommon in studies, but because supplement safety has not been fully tested, stop using idebenone and seek medical care if you have signs of an allergic reaction such as rash, swelling, or trouble breathing.

Idebenone: Reported Adverse Effects

Documented safety reports on Idebenone from the evidence-graded Natural Medicines (TRC Healthcare) database, shown word-for-word from the licensed record.

Orally, idebenone seems to be well-tolerated. In clinical studies, there have been no reports of serious adverse effects occurring more frequently than with placebo. Some people who take idebenone have experienced nausea and vomiting, abdominal pain, elevated alkaline phosphatase, and loose stools; however, these side effects are not common. High doses up to 2250 mg or 75 mg/kg per day have also been well-tolerated without a clinically significant increase in side effects.

Topically, contact allergic dermatitis has been reported, but this adverse effect is uncommon.

Idebenone: Common Questions

What is Idebenone used for, and does it work?
People use Idebenone for many reasons, but the evidence varies by use. According to the Natural Medicines database, there is at least some clinical evidence supporting Idebenone for Alzheimer disease, Leber hereditary optic neuropathy and Muscular dystrophy. For most other uses it has been studied for, the evidence is currently insufficient to rate. See the graded list on this page, and always confirm with your pharmacist or doctor.
Does Idebenone interact with prescription medications?
We do not currently list any known drug interactions for Idebenone. This does not guarantee that none exist, so always confirm with your pharmacist before combining it with your medications.
How are Idebenone interactions rated?
Each interaction is graded major, moderate, or minor based on how clinically significant it is and the strength of the evidence behind it. Major interactions are the most serious and are best avoided, or used only under close professional supervision.
Is it safe to take Idebenone with my medications?
It depends on the specific medication. Some combinations are fine, while others call for monitoring, timing changes, or should be avoided. Check your exact drug above and confirm with your pharmacist or doctor before starting, stopping, or changing anything.
Where does this Idebenone interaction information come from?
Our interaction data is built on the Natural Medicines database — an evidence-graded reference for vitamins, herbs, and supplements — and is reviewed by licensed HelloPharmacist pharmacists, who may add clinical context.
What is Idebenone used for?
Idebenone is a synthetic antioxidant similar to CoQ10. It has been studied as a prescription medicine for certain rare eye and mitochondrial conditions, and is also used in supplements and anti-aging skin products, though evidence for everyday use is limited.
Is Idebenone the same as CoQ10?
No. Idebenone is a man-made compound designed to act like coenzyme Q10, but it is a different molecule with somewhat different properties. They should not be assumed to be interchangeable.
Is Idebenone safe to take?
It has generally been tolerated in studies, but the long-term safety of over-the-counter Idebenone supplements is not well established. Talk with your pharmacist or doctor before using it, especially if you have a health condition.
Can I use Idebenone while pregnant or breastfeeding?
There is not enough reliable safety information, so it is best to avoid Idebenone during pregnancy and breastfeeding unless your doctor advises otherwise.
