Can nystatin and triamcinolone be used for fever blisters?

No, nystatin and triamcinolone are not effective for treating fever blisters. They are often used together as a topical cream to treat fungal infections of the skin, such as athlete's foot and jock itch. Nystatin is an antifungal medication, while triamcinolone is a corticosteroid used to reduce inflammation and itching.

Fever blisters or cold sores are caused by the herpes simplex virus, which is not a fungus. Antiviral medications such as acyclovir, valacyclovir, or penciclovir are commonly used to treat fever blisters. These medications work by interfering with the ability of the virus to replicate and spread. In addition to oral medication, topical preparations or patches of these medications can be applied directly to the fever blister to relieve symptoms and speed up healing.

If you have a fever blister or think you may have one, it's important to see a healthcare provider for a proper diagnosis and treatment plan. Fever blisters can sometimes resemble other skin conditions, so consulting a healthcare professional can help to ensure accurate treatment and reduce potential complications.
