There's no cure for shingles, but prompt treatment with prescription antiviral drugs can speed healing and reduce your risk of complications. These medications include:
-
Acyclovir (Zovirax)
-
Famciclovir
-
Valacyclovir (Valtrex)
Shingles can cause severe pain, so your doctor also may prescribe:
-
Capsaicin topical patch (Qutenza)
-
Anticonvulsants, such as gabapentin (Neurontin)
-
Tricyclic antidepressants, such as amitriptyline
-
Numbing agents, such as lidocaine, delivered via a cream, gel, spray or skin patch
-
Medications that contain narcotics, such as codeine
-
An injection including corticosteroids and local anesthetics
Shingles generally lasts between two and six weeks. Most people get shingles only once, but it is possible to get it two or more times.
