Hi I am having a white discoloration which itches at
Hello and welcome to Ask A Doctor service.
I have reviewed your query and here is my advice.
Among the choices I would suggest Miconazole because of its longer duration of action.
Can use cleaner water to avoid recurrent infections.
Hope this helps. Let me know if I can assist you further.
What is the recommended duration of the application. Is Dactarin Gel fine.
Recommended is twice a day
Its recommended to be applied twice a day for few days or until symptoms reduce.
Even after single application its action has been observed to continue for few days.
Is it a matter of concern or will this subside on its own.
I have no pain.
It seems angioedema
You seem to have allergic reaction to miconazole, probably its angioedema.
Kindly discontinue medicine, wash the area nicely with water, take Diphenhydramine 25 mg 3-4 times a day. It will subside by itself in 2-3 days.
But emergency care maybe needed if there is breathing difficulty. You must keep an epi-pen with you all the time. Get its prescription asap.
Though I donot expect the blood supply to be blocked to penile shaft, still it is better to get an doppler of penile shaft after consulting a physician or surgeon, if big swelling happens.
