What is the red rash on the glans penis?

Red rash on the glans penis may be caused by allergic eczema, balanitis, condyloma acuminata and other diseases.

Atopic eczema is mainly caused by exposure to allergens, such as new underwear or eating some allergic foods, which may cause a red rash on the glans, accompanied by itching and pain. It can be treated with oral medications such as cetirizine hydrochloride, loratadine tablets, and chlorpheniramine maleate tablets under the guidance of a doctor.

If the foreskin is relatively long, the local dirt may not be cleaned in time, and it may also cause recurrent episodes of foreskin balanitis, which may cause many small red bumps to appear locally, accompanied by pain and increased exudation. It can be treated with oral administration of cefixime dispersible tablets, amoxicillin capsules, roxithromycin capsules and other drugs as directed by the doctor.

Genital warts are mainly caused by human papillomavirus infection, which will cause many small warts to appear on the glans, accompanied by itching. You can go to the hospital for treatment with laser or cryotherapy.
