Basic Information On Qutenza
Qutenza is a medicated skin patch that is used for control of neuropathic pain connected with post-herpetic neuralgia. Post-herpetic neuralgia (PHN) can occur post an attack of Herpes Zoster or shingles. PHN influences the nerve fibers and can cause extreme pain that may even last for years. Qutenza is a TRPV1 channel agonist. The activation of TRP1 causes a burning pain. On prolonged exposure to this patch, TRPV1 activity decreases, this is known as desensitization. The brand or generic patch is to be administered by an experienced physician or healthcare professionals under appropriate supervision. It should be applied for a period of about 60 minutes and its effects will last for about a quarter year.
Precautions / Side Effects For Qutenza
The main active ingredient of the patch is capsaicin, the strong substance in chili peppers. As the patch is administered topically, it does not make you feel sleepy and it also does not interact with other drugs. Qutenza can cause some common adverse reactions as redness, itching and burning sensation at the site of administration of the patch. This may last for some days and the burning feeling can become acute while taking hot showers. The patch application can cause a short-term rise in pain levels; this may in turn increase your blood pressure. If you experience severe nausea, skin blisters, or allergic reaction symptoms like rash, swelling of the face, tongue, and mouth, then call your doctor immediately.
Never try and apply the patch on your own. The patch should not be administered on the face or scalp in order to protect the eyes or mucous membranes. The patch needs to be removed slowly so that the pungent ingredient does not vaporize and cause irritation of eyes or the windpipe. The exact effects of the patch on unborn or nursing babies have not been established. However, discuss with your doctor if you are pregnant or lactating.
