Efficacy of medicinal creams

[bibblebub]

I have to use a cream for psoriasis and was wondering for how long does it remain effective once on the skin?

Is the efficacy short lived so that one could have a shower after half-an-hour knowing that it will have done its work and so can be washed away, or does it continue to have an effect for several hours?

Can't answer the question unless i know the cream to which your are considering. Different creams are absorbed from the body at different rates and this even differs from different parts of the body.
Even a topical steroid will be absorbed at differing rates depending upon which steroid and to which part of the body it is applied.

Sorry.

At the moment it's usually Dovonex but I must admit that I thought it would be roughly the same for all, being either a few minutes or several hours.

I have had no experience with the drug, but clearly if it had to be applied twice daily, which I think is recommended then it probably is totally absorbed in a 12 hour period. If you had a shower, within the 12 hours, then it would need reapplying.

shower just before you are due to reapply... so you are applying onto clean skin

I always apply it after a shower so it was only a theoretical question anyway.

But thanks for answering Sqad.

I have been using Dovonex for psoriasis for a while now. It has cleared quite a few patches and has improved others. I usually apply it at night so has a chance to be absorbed into skin overnight. However, the pharmacies in my area can no longer get this cream, so am wondering what to use in place of. Any suggestions ????

Dovobet is similar and works better for me than Dovonex did.
