Dimethylglycine (dmg) and Alitretinoin

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 Alitretinoin and Dimethylglycine (dmg) 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.

Worth understanding: our licensed dataset holds no drug-interaction record for Dimethylglycine (dmg) at all — not against Alitretinoin, and not against any other medication we track. This verdict therefore rests on the absence of any recorded data, not on research that looked at this combination and found nothing. We cannot rule an interaction out.

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.

What to actually watch for

What Alitretinoin’s Own FDA Label Lists

This is not an interaction — none of it involves Dimethylglycine (dmg). These are the most notable effects listed in the ADVERSE REACTIONS section of Alitretinoin’s own FDA label, for the medication by itself. Knowing the drug’s own list makes it easier to work out the likely cause if something new turns up while you take both.

  • Sun sensitivity
  • Numbness or tingling
  • Itching
  • Swelling
  • A skin rash

From the ADVERSE REACTIONS section of the FDA label for Alitretinoin. Read the label on DailyMed › Where a percentage is shown, it is the share of 117 voluntary FDA FAERS reports for Alitretinoin that mention that effect — a reporting proportion, not an incidence rate and not evidence the drug caused it. Dimethylglycine (dmg)’s licensed record lists no adverse effects our clinical vocabulary could match, so there is no Dimethylglycine (dmg) side to compare — that is a limit of the record, not a statement that Dimethylglycine (dmg) has no side effects.

About Dimethylglycine (dmg)

What is Dimethylglycine (dmg)?

  • Athletic performance and energy
  • Autism spectrum support
  • Immune support
  • Seizure disorders
  • General wellness and detox support

Dimethylglycine (DMG) is a substance made naturally in the body and found in small amounts in foods. It is marketed for energy, athletic performance, autism, and immune support, but solid human evidence for most of these uses is limited. It appears generally well tolerated in short-term use, but talk with your pharmacist or doctor before trying it.

Not applicable (a naturally occurring amino acid derivative) · Tablets, capsules, chewable tablets, sublingual tablets, powder

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

Dimethylglycine (dmg): dosing

There is no officially established or standardized dose of DMG.

About Alitretinoin

What Is Alitretinoin Used For?

Brand name: Panretin

Panretin Gel is approved to treat cutaneous lesions — visible skin sores — in adults who have AIDS-related Kaposi's sarcoma (KS), a cancer that causes abnormal tissue to grow in the skin.

Panretin Gel is applied directly to the affected skin spots. It is not for use when the disease has spread widely enough to need systemic (whole-body) treatment — for example, when there are more than 10 new lesions in a month, or when the lungs, lymph nodes, or internal organs are involved.
