Drug & supplement interaction

Same + Isotretinoin

Isotretinoin brand names: Accutane, Amnesteem, Claravis, Sotret, Absorica, and others.

No Known Interaction
The bottom line No known interaction

We found no known interaction between Same and Isotretinoin in our sources. Absence of a documented interaction is not the same as proven safety, and does not guarantee one does not exist. Do not start, stop, or change a medication or supplement based on this page; confirm with your pharmacist or doctor first. Additionally, although there is no interaction, the two are separately associated with some of the same side effects, which would make a new symptom harder to attribute to one or the other.

Same and Isotretinoin

We checked these two against our interaction database. Here is what we found.

No Known Interaction Found

We did not find a documented interaction between Isotretinoin and Same in our sources. This does not guarantee that the combination is completely free of risk — there is often limited research on supplements and herbal products, especially around drug interactions.

If you decide to take both, the practical routine is simple: add one new thing at a time and note the date you started it. If the combination is going to disagree with you, it usually shows in the first days to a couple of weeks — and a start date turns “I’ve been feeling off” into something a pharmacist can actually work with. Do not stop a prescribed medicine on your own.

Always talk with your pharmacist or doctor before making changes to your medications or supplements, particularly if you take several medications or have an ongoing health condition.

How we checked

Why No Interaction Is Listed for Isotretinoin

Interactions in our licensed database are recorded against drug classes, not just single drug names. Isotretinoin is filed under 4 classifications — including retinoids, cytochrome p450 2c8 (cyp2c8) substrates, photosensitizing drugs. Same has documented interactions with 2 drug classes — the most serious being levodopa (moderate) and serotonergic drugs (moderate) — and none of Isotretinoin’s classifications are among them.

Classification data comes from our licensed Natural Medicines dataset. A medication can belong to classes beyond those recorded there, so this describes how the check was run — it is not a safety guarantee.

Keep it in perspective

Same Does Interact With Other Medications

Same has 189 moderate known drug interactions in our database — Isotretinoin isn’t one of them. If you take anything else, check it against the full list below.

What to actually watch for

No Interaction Found — But Data Suggests Same and Isotretinoin May Share Several of the Same Side Effects

This is not an interaction. Neither one changes how your body handles the other, and nothing here says they react together. What our sources do show is that each has separately been linked to the effects below — so taking both can make those effects more likely to turn up, and harder to pin on one or the other if they do. 2 of them are worth acting on rather than waiting out — marked below.

  • Thoughts of self-harm / Low mood Worth acting on reported in 12.1% of FDA reports for Isotretinoin Additional detail

    “Orally, anxiety and tiredness have been reported in patients with depression. Rare adverse effects associated with SAMe include hypermania. Hypomania has occurred with a combination of intramuscular and oral SAMe. Cases of mania with suicidal ideation have also been reported in otherwise healthy patients. A crawling sensation on the skin has been reported in a clinical trial.”

Reported for Same but not commonly for Isotretinoin: bleeding in the gut, vivid dreams or nightmares, bloating or gas and heartburn.

Effects for Isotretinoin come from the ADVERSE REACTIONS section of its FDA label; effects for Same come from the Natural Medicines adverse-effect record, quoted above. Where a percentage is shown, it is the share of 46,523 voluntary FDA FAERS reports for Isotretinoin that mention that effect — a reporting proportion, not an incidence rate and not evidence the drug caused it. Wording is matched across sources by our own clinical vocabulary, so treat this as a prompt to pay attention, not a diagnosis.

Same in Pregnancy & Breastfeeding

Pregnancy Possibly Safe

When used intravenously short-term during the third trimester of pregnancy. In two small-scale trials, SAMe 800 mg daily was used intravenously for 14-20 days during the third trimester of pregnancy for cholestasis. No adverse effects were observed. However, use of SAMe in pregnancy should only be considered when benefits clearly outweigh the potential risks. There is insufficient reliable information available about the use of SAMe at higher doses, for extended periods of time, or during the earlier trimesters of pregnancy.

See Every Supplement That Interacts With Isotretinoin

This page covers Same only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Isotretinoin page lists 49 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Activated Charcoal (major), Vitamin A (major), African Wild Potato (moderate), Alfalfa (moderate) and Angelica Archangelica (moderate).

By severity: 2 major · 35 moderate · 12 minor.

From our pharmacist’s overview on the Isotretinoin page

“Vitamin A is the first thing anyone on isotretinoin (Accutane, Absorica, Claravis) should check their supplements for, because isotretinoin is itself a vitamin A derivative and stacking more on top can push levels into toxic range. It is one of two major-rated entries among the 49 supplements and herbs known to interact with this acne…”

About Same

What is Same?

Same
  • Depression
  • Osteoarthritis joint pain
  • Liver conditions
  • Fibromyalgia

SAM-e is a compound your body makes naturally that is sold as a supplement, most often for depression and osteoarthritis. Some research suggests it may help with these conditions, but the quality of evidence is mixed and more study is needed. Talk with your pharmacist or doctor before trying it, especially if you take other medicines or have bipolar disorder.

Not a plant; a compound made naturally in the body (supplements are made synthetically) · Enteric-coated tablets, capsules; less commonly injectable (used in some countries under medical supervision)

An interaction check asks whether these two react with each other — it does not ask whether Same is a good idea for someone in your situation. Here is what our Same record says about it on its own.

Same: dosing

There is no single official standardized dose of SAM-e, and the amount studied has varied depending on the condition and the salt form used. SAM-e is often sold as enteric-coated tablets to help it survive stomach acid, and some people take it before meals.Do not assume more is better. Starting low and using the lowest helpful dose may reduce the chance of side effects.

About Isotretinoin

What Is Isotretinoin Used For?

Brand names: Accutane, Amnesteem, Claravis, Sotret, Absorica, Roaccutane

Isotretinoin is used to treat severe recalcitrant nodular acne — large, deep, inflamed breakouts (nodules 5 mm or bigger) that haven't cleared with conventional treatments like antibiotics. It is approved for non-pregnant patients 12 years of age and older. Brands include Absorica, Absorica LD, Accutane, Amnesteem, Claravis, and generic isotretinoin capsules.

Because of its serious potential side effects, isotretinoin is reserved for patients whose acne is truly severe and has not responded to other standard treatments. A typical course lasts 15 to 20 weeks, and many patients experience prolonged remission — sometimes permanent clearing — after a single course.

Most-Reported Side Effects for Isotretinoin

From FAERS, the FDA’s public side-effect reporting system (46,523 reports, all brands). Reports are voluntary and are not proof the drug caused the effect.

Depression 5,609 reports
Inflammatory bowel disease 5,250 reports

Taking Same and Isotretinoin Together: Common Questions

Is it safe to take Same with Isotretinoin?
We do not list a known interaction between Same and Isotretinoin. That does not guarantee the combination is risk-free, so confirm with your pharmacist or doctor — especially if you take other medications or have a health condition.
Do Same and Isotretinoin have any of the same side effects?
Yes — our sources link each of them separately to 10 of the same effects. That is not an interaction: neither changes how your body handles the other. It does mean that if one of those effects turns up, it can be harder to tell which one is behind it. They are listed on this page with the source behind each.
How was the Same and Isotretinoin combination checked?
Interactions in our licensed database are recorded against drug classes. Isotretinoin is filed under 4 classifications, and Same has documented interactions with 2 drug classes — none of Isotretinoin's classifications are among them. A medication can belong to classes beyond those recorded in our dataset, so this describes how the check was run rather than guaranteeing safety.
Does Same interact with any other medications?
Yes. Same has 189 documented drug interactions in our database — Isotretinoin is simply not one of them. If you take anything else, it is worth checking each one; they are all listed on this page.
Does Isotretinoin interact with any supplements?
Yes. Isotretinoin has documented interactions with 49 supplements in our database — Same is not one of them. The Isotretinoin interaction page linked on this page lists every one, ranked by severity.
