Agreed ! I strongly advise following your Dr's directions but just as well I advise that you learn as much as you can about it and relay that information to your Dr.
Is your Dr aware of the new research and the synergy provided by Celebrex?
The treatment is 70% more effective with it.
Additionally, you should (as should everyone) on this treatment verify any information they are considering with the manufacturer.
There are people recommending solutions that are certain to aggravate and burn Efudex treated skin. They contain many chemicals and irritants.
However, the same soothing relief you receive from a new application of Efudex comes from the white petroleum base that is 95% of the creme.
To the best of my knowledge, Valeant will only recommend white petroleum jelly (Vaseline) to be used after a 3 hour wait and on top of the Effudex when irritation, pain and tightness become an issue. (and they will).
Any of these other solutions may cause harm and any other interval may reduce the effectiveness.
