Is cvs antibiotic and pain relief cream on genital area ok for itching?

Probably not. Since the cause of the itching is not known, the above cream may relieve the symptom without treating the cause. You should see your physician to determine a definitive treatment, such as an anti-funga medication if the itching is due to a yeast infection.
Depends. Depends on why you itch. If you have a fungal or other type infection, then no, possibly not good enough. Try it but if it doesn't help soon, time to seek professional advise.
