Ketoconazole - Can you use this cream on itchy bumps on your skin?

Ketoconazole has many, many side effects. I would not use this cream unless
your doctor prescribes it. If you wish you can look up the side effects of this
cream - then you will be better informed.
However, I would make an appointment with your doctor to get checked out before
you use any type of cream or liquid on your body.
Good luck and I hope you find help and relief with your medical problem.
