Nasal ulcers may be caused by the Herpes Simplex Virus. The best treatment is usually to allow them to heal over the course of a few weeks, according to eMedicine Health. However, medications may be used to keep the ulcers from drying out or to reduce pain.
The treatment of a nasal ulcer is usually to just leave it alone and allow it to heal. There are medications that can help external sores caused by herpes to heal faster, such as Docosanol, Denavir and Zovirax creams, according to eMedicine Health. Follow the directions closely when applying these medications and ask a doctor about using them on any ulcer that may appear inside the nose. Certain topical medications are absorbed more readily through mucosal membranes. Reoccurring or non-healing ulcers should be looked at by a doctor, as there may be an underlying health condition.
When an ulcer is very painful, doctors may prescribe a topical cream to numb the area, including benzocaine, lidocaine and tetracaine. Taking an oral pain reliever, such as ibuprofen, may also help.
The light application of petroleum jelly may also help keep the sore moist. If looking to keep an ulcer inside the nose moist, petroleum jelly may be safe when used very short term, according to Mayo Clinic. However, a water-based lubricant may be a better choice.
