From the Guidelines
Tongue shingles, or herpes zoster of the tongue, should be treated with antiviral medications such as acyclovir, valacyclovir, or famciclovir for 7-10 days to reduce the severity and duration of symptoms. The treatment of choice for VZV infections, including tongue shingles, is high-dose intravenous acyclovir, especially in compromised hosts 1. However, for otherwise healthy hosts, oral acyclovir, famciclovir, or valacyclovir can be beneficial, and oral therapy should probably be reserved for mild cases of VZV disease in patients with transient immune suppression or as treatment to complete therapy once the patient has shown a clinical response to intravenous acyclovir 1.
Some key points to consider in the management of tongue shingles include:
- Starting antiviral medication within 72 hours of rash onset for maximum effectiveness
- Using over-the-counter pain management options like acetaminophen or ibuprofen for mild pain
- Considering prescription medications such as gabapentin or lidocaine mouthwash for severe pain
- Keeping the affected area clean and maintaining good oral hygiene
- Avoiding spicy or acidic foods that may irritate the tongue
Tongue shingles occurs when the dormant varicella-zoster virus in nerve tissues reactivates and travels along nerve pathways to the tongue, causing painful blisters and sores 1. The condition typically resolves within 2-4 weeks, but prompt treatment can reduce the severity and duration of symptoms, as well as lower the risk of complications like postherpetic neuralgia, which causes persistent pain after the rash heals.
In terms of prevention, oral acyclovir, famciclovir, or valacyclovir can be used to prevent viral reactivation in high-risk patients during the period of maximum immunosuppression 1. Recipients of an allogenic blood and bone marrow transplant routinely take acyclovir or valacyclovir during the first year after transplantation to prevent VZV reactivation 1.

From the Research
Tongue Shingles Overview
- Tongue shingles, also known as herpes zoster, is a viral infection caused by the Varicella Zoster virus 2, 3.
- The infection can cause pain, rash, and blisters on the tongue and other parts of the body 4, 5.
Treatment Options
- Oral antiviral agents, such as acyclovir, valacyclovir, and famciclovir, are commonly used to treat herpes zoster 2, 3, 4, 5.
- These medications can help reduce the severity and duration of symptoms, including pain and rash 2, 3, 4, 5.
- Valacyclovir has been shown to be more effective than acyclovir in hastening the healing of zoster-associated pain and postherpetic neuralgia 3, 5.
- Combination therapy with valacyclovir, methylprednisolone, and pregabalin may have better efficacy in managing acute herpes zoster neuralgia compared to valacyclovir alone or valacyclovir with pregabalin 6.
Efficacy and Safety
- The efficacy and safety of different doses of antiviral agents in the treatment of herpes zoster have been evaluated in several studies 4, 5, 6.
- The results suggest that 800 mg of acyclovir, 900-1000 mg of valacyclovir, and 250 mg of famciclovir, all taken three times a day, are effective and safe treatment options for herpes zoster 4.
- Valacyclovir has been shown to be safe and effective in the treatment of patients with herpes simplex and herpes zoster, and may be useful in other viral infections 5.
