Balanitis can be treated with oral antibiotics to achieve antibacterial effect, and some potassium permanganate can also be used externally to defoaming. For external use of potassium permanganate, there are several precautions. The most important one is not to have too high concentration. It is recommended that patients use potassium permanganate in this way, that is, find a small cup, put a cup of warm water, take out a piece of potassium permanganate, cut it into four or two parts, take 1/4 or 1/2 of it, and put it into a cup to dissolve. At this time, its concentration is not very high. Put 1/2 or 1/4 of potassium permanganate into the small cup, dissolve it, and soak the penis into the small cup to play an anti-inflammatory role. For prepuce balanitis, the most important healing treatment is to perform circumcision, because prepuce balanitis is often caused by long-term prepuce dirt stimulating balanitis.
