Shingles, also known as herpes zoster, is a viral infection caused by the reactivation of the varicella-zoster virus—the same virus responsible for chickenpox. This painful rash typically affects one side of the body and can lead to severe discomfort and complications if left untreated. In this article, we’ll explore how shingles is treated, the available medications, lifestyle modifications, and when to seek medical attention.
Understanding Shingles and Its Symptoms
Before diving into treatment options, it’s important to recognize the symptoms of shingles:
- Pain and tingling: A common early symptom of shingles is a sharp or burning pain, typically on one side of the body or face.
- Rash: After a few days of pain, a red rash develops. The rash then forms small fluid-filled blisters that scab over after 7 to 10 days.
- Other symptoms: Some individuals experience fever, headache, chills, and fatigue along with the rash.
Early diagnosis and treatment are crucial to reducing the severity and duration of symptoms, as well as minimizing the risk of complications.

Antiviral Medications: The First Line of Defense
The most effective treatment for shingles involves antiviral medications. These drugs work best when taken within 72 hours of the onset of symptoms.
Common antiviral medications include:
These medications help to:
- Reduce the duration of the outbreak.
- Alleviate the severity of symptoms.
- Lower the risk of complications like postherpetic neuralgia (persistent pain even after the rash heals).
Dosage and Duration
The typical course of antiviral treatment lasts for 7 to 10 days, but your doctor will provide specific instructions based on the severity of your symptoms.

Pain Management for Shingles
Shingles can cause intense pain, which requires proper management alongside antiviral therapy. There are several options for pain relief, depending on the severity of the discomfort:
1. Over-the-counter pain relievers
Mild to moderate pain can often be managed with:
- Ibuprofen or Aspirin: These are nonsteroidal anti-inflammatory drugs (NSAIDs) that can help with pain and inflammation.
- Acetaminophen (Tylenol): This can relieve pain without the anti-inflammatory effects of NSAIDs.
2. Prescription medications for more severe pain
If OTC pain relievers are not enough, a doctor may prescribe:
- Opioids like codeine for short-term relief of severe pain.
- Anticonvulsants (e.g., gabapentin) or antidepressants (e.g., amitriptyline) can also help with nerve pain.
3. Topical treatments
- Lidocaine patches or capsaicin cream can be applied directly to the rash to numb the skin and reduce discomfort.
4. Nerve blocks
In extreme cases where pain is unmanageable, a doctor may recommend nerve blocks—an injection of an anesthetic that numbs the affected area.
Preventing Complications: Postherpetic Neuralgia
One of the most common complications of shingles is postherpetic neuralgia (PHN), a condition where nerve pain persists for months or even years after the rash has healed. Antiviral medications can lower the risk of developing PHN, but additional treatments are sometimes necessary:
- Tricyclic antidepressants: These are often used to treat chronic nerve pain.
- Anticonvulsants: Medications like gabapentin or pregabalin are commonly prescribed to manage PHN.
- Lidocaine patches: For local pain relief in areas affected by PHN.
Complementary and Home Treatments for Shingles
In addition to prescription medications, some home remedies and lifestyle changes can help ease shingles symptoms and support recovery.
1. Cool compresses
Applying a cool, damp washcloth to the rash several times a day can reduce pain and itching. Make sure to use gentle materials to avoid irritating the skin.
2. Oatmeal baths
Soaking in a colloidal oatmeal bath can soothe irritated skin and relieve itching. Oatmeal has anti-inflammatory properties that can provide comfort.
3. Proper hygiene
It’s essential to keep the rash clean and dry to prevent bacterial infections. Avoid scratching the blisters to reduce the risk of scarring.
4. Stress management
Shingles can be triggered by stress, so relaxation techniques like yoga, meditation, and deep breathing exercises may help prevent future outbreaks.
When to Seek Medical Attention
While many cases of shingles can be treated at home with prescribed medications, certain situations require immediate medical attention:
- Shingles affecting the eye (ophthalmic shingles): If the rash or pain spreads to your face, especially around the eyes, seek urgent care to avoid vision loss.
- Widespread rash: If shingles covers a large area of the body or affects multiple parts of the body.
- Severe pain or neurological symptoms: If you experience muscle weakness, confusion, or persistent numbness, it’s important to consult a doctor.
The Importance of the Shingles Vaccine
To reduce the risk of developing shingles, particularly in adults over 50, the Shingrix vaccine is highly recommended. This vaccine has been shown to be more than 90% effective at preventing shingles and its complications.
The vaccine is especially crucial for:
- Adults aged 50 and older.
- Individuals with weakened immune systems, such as those with HIV, cancer, or those undergoing chemotherapy.
Even if you’ve had shingles before, the vaccine can help prevent future outbreaks.
Conclusion
Treating shingles effectively requires a combination of antiviral medications, pain management strategies, and home remedies. Early intervention is key to reducing symptoms and preventing complications like postherpetic neuralgia. If you’re at risk for shingles, getting vaccinated can offer significant protection. Always consult a healthcare professional to determine the best course of treatment for your specific situation.
