The varicella-zoster virus causes shingles (Herpes zoster), the same virus that causes chickenpox. After recovering from chickenpox, the virus remains dormant in the nervous system and can reactivate later in life when the immune system is weakened. Shingles typically form a rash of blisters that crust over in about three days and heal within two to four weeks. The rash usually appears band-like on one side of the body, often around the abdomen, face, or limb.
Symptoms range from mild discomfort to excruciating burning pain, and some individuals may experience pain without a visible rash.
Early Treatment for Shingles
The best time to start antiviral shingle treatment is within 72 hours of the onset of symptoms. This is when the medication is most effective, as the virus is actively reproducing. If new lesions continue to appear beyond 72 hours, antiviral therapy may still be beneficial. Once the lesions have crusted over, antiviral therapy is usually ineffective and not recommended.
Antiviral medications are most effective in patients older than 50, as they tend to experience longer-lasting pain. The efficacy in younger patients has yet to be well known.
Antiviral Medications
Antiviral medications, specifically nucleoside analogs, are the preferred treatment for shingles. These medications work by mimicking molecules in viral DNA, thereby preventing the virus from reproducing. The most commonly prescribed antivirals for shingles are valacyclovir, famciclovir, and acyclovir. Valacyclovir and famciclovir are preferred due to their less frequent dosing requirements, but all three are equally effective. The typical dosages are:
- Valacyclovir: 1000 mg three times per day for seven days
- Famciclovir: 500 mg three times per day for seven days
- Acyclovir: 800 mg five times per day for seven days
Complications of Shingles
The potential complications of shingles can be severe. The most common is postherpetic neuralgia (PHN), a painful and debilitating condition that can persist for weeks or even years. Other serious complications, though rare, can include blindness, hearing loss, encephalitis, and kidney disease, depending on which nerve is affected. This underscores the importance of prevention and early treatment.
Prevention of Shingles
The Centers for Disease Control and Prevention (CDC) recommends the recombinant zoster vaccine (RZV, Shingrix) for adults aged 50 and older to prevent shingles. This vaccine is available from pharmacists without a prescription, significantly reducing the risk of developing shingles and its complications.
