Terbinafine Hydrochloride Solution can only be used to treat fungal glans, and is not effective in treating other causes of glans, such as bacterial glans and trichomoniasis. Terbinafine hydrochloride solution is a broad-spectrum antifungal drug, which can highly selectively inhibit fungal squalene cyclooxygenase and block the formation of fungal cell membranes, thus exerting the effect of inhibiting and killing fungi, so it can be used for the treatment of fungal glans dermatitis. Bacterial glans is caused by streptococcus, staphylococcus aureus and other bacterial infections, so the use of terbinafine hydrochloride solution has no therapeutic effect, you can use boric acid water, isacridine solution, erythromycin and other drugs for treatment.

If you suffer from glans, do not blindly use drugs, it is recommended to consult a doctor in a timely manner to identify the cause and ask the doctor to dispose of it.
