Lidocaine or Topical Cortisone Creams: Pros and Cons of Itching Remedies
Itching can arise from a wide variety of causes, which are not always obvious. Irritations, allergies, or specific skin conditions can make the skin red and lead to the uncontrollable desire to scratch. To alleviate this unpleasant sensation, many seek effective solutions, either through the use of medications or the application of natural remedies. Cortisone creams and antihistamines are very good for reducing inflammation, while anesthetics such as lidocaine and benzocaine immediately calm the discomfort but, like all drugs, they have side effects that are important to know about. Aloe vera, with its soothing properties, and tea tree essential oil, known for its antibacterial properties, have become focal points in the research of those who need relief from mild itching without repercussions on health. Here is a small informative guide to help those looking for a targeted approach to this annoying problem, balancing between the practicality of traditional medicine and the growing appeal towards more natural and delicate solutions for the skin.
What is itching?
Itching, the common sensation that leads to scratching, arises from the complex interaction between the skin, nerve endings, and the central nervous system. Despite numerous attempts to classify it as a well-defined sensory experience, and despite the similarities to pain mechanisms, itching remains elusive in its nature. However, it is known that it can be triggered by various stimuli, including mechanical, chemical, thermal, and electrical ones, as well as by infections or medical conditions. This mechanism is closely linked to a defense response of the body, since scratching can help remove potential irritants from the skin. However, it is essential to understand that excessive abrasion can trigger a vicious cycle: the very act of scratching can damage the skin barrier, increasing the risk of infections and making the situation worse. Instead, it is better to look for solutions that alleviate the disorder in a delicate way, such as the application of specific creams or the adoption of targeted remedies that respect the integrity of the skin.
Anti-itch drugs: lidocaine and benzocaine
Lidocaine and benzocaine are drugs belonging to the class of local anesthetics; that is, they are capable of temporarily blocking the conduction of nerve impulses and therefore alleviating itching, even, for example, in the case of sunburn. It is found in pharmacies in the form of creams, gels, eye drops or ointments that can be applied directly to the affected area. Its analgesic and antipruritic action offers rapid relief but, especially in the long term and on large areas of the body, it can lead to important side effects, even at a systemic level, including allergic reactions and cardiovascular problems. Before using lidocaine, it is always advisable to consult a doctor to evaluate your specific situation and ensure safe and effective use of the drug.
Corticosteroid drugs for itching
Corticosteroids are a class of steroidal anti-inflammatory drugs, similar to corticosteroid hormones naturally produced by the adrenal glands. They can be used to treat a wide range of conditions, including inflammatory skin disorders such as eczema or dermatitis, in the form of creams or ointments. Their anti-inflammatory action reduces redness, swelling, and irritation of the skin, helping to relieve the sensation of discomfort. Topical steroids can be classified into different categories based on their potency, from milder ones suitable for sensitive areas such as the face, to more potent ones intended to treat thicker or tougher areas of the skin. They are very effective, but it is important to use them with caution and under close medical supervision. Prolonged or excessive use of topical corticosteroids can, in fact, cause drug interactions or side effects, including thinning of the skin, appearance of streaks, excessive pigmentation.
Natural remedies against itching: Aloe Vera and Tea Tree
Aloe vera is a succulent plant with fleshy leaves that contains a gelatinous substance rich in active ingredients beneficial to health. This plant is particularly prized for its soothing and hydrating properties, making it a popular choice as a natural remedy for various skin ailments. The gel extracted from aloe vera leaves is often used to relieve itching thanks to its anti-inflammatory and refreshing properties. Tea tree oil has gained popularity thanks to its notable antimicrobial, antifungal, and anti-inflammatory properties which make it a valid natural ally against itchy skin. Properly diluted and applied topically, tea tree essential oil can help soothe irritated skin and reduce the sensation of discomfort.
In conclusion, while traditional medications such as lidocaine and corticosteroid creams are effective for itching, they come with potential side effects. Natural remedies like aloe vera and tea tree oil offer gentle, soothing alternatives for itchy skin without the associated risks. It is important to consult a healthcare professional before using any new medications or remedies to ensure safe and effective treatment.
