Topical Preparations
Sciatica can be debilitating, making it difficult to stand, sit, or walk for extended periods. Fortunately, there are a few topical preparations that can provide relief from sciatica pain.
Capsaicin cream is derived from chili peppers and works by causing the body to release chemicals that reduce pain signals. Capsaicin cream is available over the counter and should be applied to the affected area three to four times per day. The side effects of capsaicin cream include burning and stinging sensations at the application site. It is recommended not to apply capsaicin cream to broken skin or open wounds. Observe proper handwashing to avoid accidentally exposing the eyes or nose to the chili pepper extract.
Lidocaine is a local anesthetic that numbs the nerves that transmit pain signals from the application site to the brain. Lidocaine patches are available by prescription and should be applied every twelve hours for up to seventy-two hours at a time. Side effects of lidocaine patches include dizziness, headache, nausea, vomiting, drowsiness, anxiety, blurred vision, dry mouth, loss of appetite, constipation, diarrhea, and weight loss. Lidocaine patches are contraindicated in patients with a heart disease or congestive heart failure.
