Your dermatologist can make an accurate diagnosis and tell you how to get rid of the bugs. However, in some cases, lice, scabies, and bed bugs can lead to an itchy rash that is not as easily recognized or not discovered as quickly.

Severe itching can result from a skin condition. If you have chronic itchy skin and are “itching” for answers about what you can do to relieve itching, please read on. It can be the result of relatively minor skin conditions like dry skin, bug bites, or poison ivy or more serious conditions like liver disease or cancer. First Generation (Sedating) Antihistaminesĭimetapp Children's ND Non-Drowsy Allergyįor ratings, users were asked how effective they found the medicine while considering positive/adverse effects and ease of use (1 = not effective, 10 = most effective).Itchy skin (medical term: pruritus) can occur in a wide range of conditions. Common antihistamines available in the U.S. Most second-generation antihistamines do not cause drowsiness, although some (such as cetirizine and fexofenadine), may be more likely to do so at higher dosages. They act on histamine-1 receptors in the periphery and are unlikely to penetrate the brain, so are less likely to cause side effects or interact with drugs. Second generation (non-sedating) antihistamines were developed in the 1980s and are much less sedating than first-generation antihistamines. Interactions with other drugs are more common with first-generation antihistamines compared with second-generation antihistamines. They are also more likely than second-generation antihistamines to impair a person’s ability to drive or operate machinery. This means that first-generation antihistamines are more likely to cause side effects such as sedation, dry mouth, dizziness, low blood pressure, and a rapid heart-beat. They also act on muscarinic, alpha-adrenergic, and serotonin receptors. They act on histamine receptors in the brain and spinal cord and in the rest of the body (called the periphery). second-generation antihistamines (also known as non-sedating antihistamines because they don't tend to cause drowsiness, although they may do so in some people).įirst-generation (sedating) antihistamines were developed more than seventy years ago and are still in widespread use today.first-generation antihistamines (also known as sedating antihistamines because they all cause drowsiness).What are the differences between antihistamines?Īntihistamines can be classified into two main categories: some symptoms of Parkinson’s disease in people unable to tolerate traditional medications for Parkinson's disease.Sedating antihistamines (see explanation below) also act in the brain and spinal cord, and on other receptors. This makes antihistamines very effective for the treatment of: What are antihistamines used for?Īntihistamines can help relieve the symptoms of an allergic reaction, such as: Histamine-1 receptors are also found in the brain and spinal cord and first-generation antihistamines (sedating antihistamines) can cross through the blood/brain barrier into the brain and act on these receptors, causing sleepiness ( sedation), and drowsiness. Allergens, such as pollen or pet fur can stimulate these receptors, causing the release of histamine, which results in symptoms such as a rash, sneezing, a runny nose, or a narrowing of the airways (also called bronchoconstriction). Histamine-1 receptors are located in your airways (breathing tubes), blood vessels, stomach, and esophagus (throat area). Antihistamines block histamine release from histamine-1 receptors and are mostly used to treat allergies or cold and flu symptoms, although some first-generation antihistamines (also called sedating antihistamines) may be used for other conditions, such as nausea or motion sickness. ![]()
