Interaction report

Procaine and Adapalene, Benzoyl Peroxide

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 Adapalene, Benzoyl Peroxide and Procaine 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 Adapalene, Benzoyl Peroxide

Interactions in our licensed database are recorded against drug classes, not just single drug names. Adapalene, Benzoyl Peroxide is filed under a single classification — topical drugs. Procaine has documented interactions with 5 drug classes — the most serious being digoxin (lanoxin) (major), skeletal muscle relaxants (major) and succinylcholine (major) — and none of Adapalene, Benzoyl Peroxide’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.

This is not an interaction — nothing below involves Adapalene, Benzoyl Peroxide. It is the side-effect record for Procaine on its own, from the licensed Natural Medicines monograph. If something new turns up after you add Procaine, this list is the first place to look.

Everything above comes from the Natural Medicines adverse-effect record for Procaine — expand a row for the licensed statement it rests on. We read the ADVERSE REACTIONS section of Adapalene, Benzoyl Peroxide’s FDA label too, and the two lists don’t meaningfully overlap — which is why no Adapalene, Benzoyl Peroxide column appears here.

From our pharmacist’s overview on the Adapalene, Benzoyl Peroxide page

“Adapalene with benzoyl peroxide (Epiduo Forte, Tactuo) is an acne gel that works on the skin surface, so its supplement interactions are fewer and quieter than most oral medicines carry. Only three ingredients appear here, none rated major, and every one of them is something applied to the skin rather than swallowed.”

About Procaine

What is Procaine?

Local anesthesia (medical/dental use)
Marketed 'anti-aging' supplements
General well-being and vitality claims
Mood and energy support (unproven)

Procaine is a synthetic local anesthetic (best known by the brand name Novocaine) used by doctors and dentists to numb tissue. It is not a true dietary supplement or herb, and the 'anti-aging' products built around it (such as GH3 or 'Gerovital') have weak evidence and real safety concerns. Talk to your pharmacist or doctor before using any product containing procaine.

Synthetic chemical compound (procaine hydrochloride) · Injectable solution (prescription), and in some products labeled 'procaine' or 'GH3' marketed as anti-aging supplements

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

Procaine: dosing

There is no established or recommended supplement dose for procaine. Because the benefits are unproven and the risks are real, many pharmacists would advise against using these products at all.

From our Procaine monograph — the full record covers uses, side effects and every documented interaction.
