In all of your internet searching for treatments, have you ever come across a FDA approved, prescription-only treatment that claims to have no active ingredients ?

Would you stop and think What is that all about? Well I did.

The supporting web site for Promiseb Topical Cream  (online at contains a very interesting insight into the Promiseb product itself ;

What is the active ingredient in Promiseb Cream?

Promiseb Cream is a prescription-only, nonsteroidal FDA-cleared medical device and has no active ingredient. However, Promiseb Cream has demonstrated both anti-inflammatory and antifungal properties.

The makers of Promiseb, Promius Pharma, do say that those who are allergic to shea butter or shea nut oil should not use their product though.

Promiseb Ingredients

Purified Water, Isohexadecane, Butyrospermum parkii, Pentylene glycol, Ethylhexyl palmitate, Cera alba, PEG-30 Dipolyhydroxystearate, Bisabolol, Polyglyceryl-6 polyricinoleate, Tocopheryl acetate, Hydrogenated castor oil, Acifructol complex, Butylene glycol, Magnesium sulfate, Piroctone olamine, Allantoin, Magnesium stearate, Disodium EDTA, Vitis vinifera, Ascorbyl tetraisopalmitate, Glycyrrhetinic acid, Propyl gallate, and Telmesteine.

What Does This All Mean?

It does seem to be an unusual situation; a prescription only medicine that claims to have no active ingredients.

We do know that the vehicle used in prescription products can be helpful on their own, and the whole spectre of The Placebo Effect is one that can’t be ignored, but in this case I suspect one of the designated inactive ingredients is actually beneficial.

An unusual finding, don’t you think?

    was there any further follow up on this? I would like to know more about Promiseb. I don’t understand why it is by Rx only if there is no Rx material in it. Can the castor oil in this be used by itself? or the shea butter? What makes this particular blend helpful (and it does help, I have used it in the past).

  2. Thomas Lavin says:

    Maybe the Piroctone olamine but the cream is very good.

  3. I’m a board-certified dermatologist. Promiseb was FDA approved as a medical device, not a medication. Shea butter (Butyrospurmum parkii) has some natural anti-Malassezia activity and anti-inflammatory activity. There are other creams marketed as medical devices instead of medications such as Atopiclair, Mimyx Cream (but they do require a prescription!)
