An outbreak of shingles can be extremely uncomfortable, causing a rash and a burning pain that is hard to control. Zostrix, one brand of the analgesic medication capsaicin, can help reduce shingles pain. The topical medication is available in without a prescription and can be used in conjunction with cortisone and antiviral medications.
Identification
Capsaicin comes from the cayenne pepper plant. The spicy plant is not only useful in livening up foods, but it can also dull pain when applied directly to the skin. The Memorial Sloan-Kettering Memorial Cancer Center reports that capsaicin is thought to reduce pain sensation by temporarily depleting a substance P, a neurotransmitter that relays pain signals to your brain. In addition to relieving shingles pain, Zostrix may also be helpful in treating pain due to diabetic neuropathy, arthritis, sprains and cluster headaches.
Application
You should apply Zostrix directly to your skin 3 to 4 times per day. You may notice a burning sensation after applying the cream, although the sensation may gradually diminish with regular usage. After you apply Zostrix, you may also notice that you skin looks slightly red. Redness may decrease with regular usage. If you still experience significant burning or redness after using the product for two or more weeks, your doctor may recommend that you decrease the number of times you apply Zostrix or use a lower strength. Wash your hands thoroughly after using Zostrix. If your shingles rash is on your hands, wait 30 minutes and then wash your hands.
Considerations
Using Zostrix may not only help with shingles pain, but may also reduce your risk of developing postherpetic neuralgia, according to Medline Plus. Postherpetic neuralgia occurs in some people after the shingles rash heals. Although you may no longer see any sign of shingles, the infection can cause nerve damage in some cases. Postherpetic neuralgic can cause mild to severe pain that can last several months or longer, depending on the extent of the damage to your nerves.
Warning
Talk to your doctor before using Zostrix and inform him of all medications you are taking. In some cases, medications may interact with Zostrix. Applying Zostrix to open, infected or broken skin can irritate the skin and worsen your problem. Using Zostrix may make your skin more sensitive to sun. Using a sunscreen whenever you are outdoors can help you avoid a sunburn. In rare cases, serious side effects may occur. Stop using Zostrix and seek medical attention if you experience shortness of breath, difficulty breathing, cough, wheezing or a tight feeling in your chest.
