Can you use triamcinolone acetonide cream for shingles?

Hello, no it will not help

Triamcinolone topical (Cinolar, Kenalog, Triderm)
Triamcinolone is a topical steroid. It reduces the actions of chemicals in the body that cause inflammation, redness, and swelling.

Triamcinolone topical is used to treat the inflammation caused by a number of conditions such as allergic reactions, eczema, and psoriasis. The dental paste form of triamcinolone is used to treat mouth ulcers.

I recommend
Acyclovir (Zovirax)
Valacyclovir (Valtrex)
Famciclovir (Famvir).

They all treat HZ or shingles very effectively ask your doctor

Take care
