Itching, medically known as pruritus, is a sensation that provokes the desire or reflex to scratch. It’s a common condition with numerous causes such as skin conditions (like eczema or psoriasis), allergic reactions, insect bites, certain diseases (like liver disease or kidney failure), or even reactions to certain medications. Itching can be localized, affecting just one area, or it can be generalized, affecting the whole body. Sometimes, itching may be linked with a rash, but it also often occurs without any visible skin changes.
Causes of Itching
Itching, also known as pruritus, can have many different causes, including:
1. Dry skin: This is a common cause of itching, and can be worsened by conditions such as cold weather and frequent bathing.
2. Irritation or allergic reactions: When your skin comes in contact with certain substances, it can cause itching. Common irritants include soap, certain fabrics, cosmetics, and certain plants like poison ivy.
3. Skin conditions or diseases: Certain skin conditions, including eczema, psoriasis, dandruff, lice, and hives, can cause itching. Infections, such as fungal infections, can also lead to itching.
4. Internal diseases: Itching can sometimes be a symptom of more serious internal diseases, such as liver disease, kidney failure, thyroid problems, diabetes, or certain types of cancers.
5. Rashes or dermatitis: Progressive stages of certain skin conditions that cause inflammation and rashes can also lead to itching.
6. Medication: Some drugs (like antibiotics, antifungal drugs or narcotics) can cause itchy skin as a side effect.
7. Pregnancy: Some women experience itchy skin during pregnancy, especially on the abdomen and thighs.
8. Nerve disorders: Conditions that affect the nervous system such as multiple sclerosis, diabetes mellitus, pinched nerves can also cause itching.
In many cases, the reason may not be so clear, and it is advisable to see a doctor if persistent or severe itching occurs and you are unable to identify a probable cause. Having a healthcare professional examine you can help rule out potential serious causes and provide the right course of treatment.
Risk Factors of Itching
Itching, also known as pruritus, can be caused by a number of factors, which are the risk factors here. The following are the common causes:
1. Dry Skin: This is perhaps the most common cause of itching, particularly among the elderly. This can be due to environmental factors like hot or cold weather, over-washing, or use of harsh soaps.
2. Allergies: Allergic reactions to things like food, insect bites, medicine, chemicals or certain materials like latex can cause severe itching.
3. Dermatological Conditions: Certain skin conditions such as eczema, psoriasis, hives, lice, chickenpox and scabies are often associated with intense itching.
4. Systemic Diseases: Some diseases affecting the whole body, such as liver disease, kidney failure, iron deficiency anemia, thyroid problems and certain cancers, including lymphoma and leukemia, can cause itching.
5. Nerve Disorders: Conditions that affect the nervous system — such as multiple sclerosis, diabetes mellitus, pinched nerves and shingles (herpes zoster) — can cause itching.
6. Psychiatric Illness: In some cases, people may feel itchy due to psychological factors, like stress and anxiety. This is called psychogenic itching.
7. Certain Medications: Some drugs, such as antibiotics, antifungal drugs or narcotic pain medications, can cause or worsen itching.
8. Pregnancy: During pregnancy, some women experience itching due to hormonal changes or conditions such as obstetric cholestasis.
Also, being exposed to these risk factors doesn’t mean that you’ll definitely have itching. It just raises the chances. It’s always crucial to consult with a healthcare provider for a proper diagnosis and treatment.

Medications commonly used for Itching
There are several types of medications commonly used to treat itching, also known as pruritus:
1. Antihistamines: These are commonly used for itchiness associated with allergies or insect bites. Antihistamines work by blocking histamine, a chemical in the body involved in allergic reactions. Examples include diphenhydramine (Benadryl) and cetirizine (Zyrtec).
2. Corticosteroids: These are applied topically and can reduce inflammation and itching. Hydrocortisone is one example and is available over-the-counter in low doses.
3. Calcineurin inhibitors: Calcineurin inhibitors such as tacrolimus (Protopic) and pimecrolimus (Elidel) are used to treat chronic itching conditions like eczema.
4. Antidepressants: Some types of antidepressants, such as doxepin, have antihistaminic properties and can help with severe itching.
5. Topical anesthetics: Topical anesthetics, like pramoxine, can provide on-the-spot relief by numbing the skin.
6. Topical Immunomodulators: These medicines, such as pimecrolimus and tacrolimus, are usually recommended for skin conditions like eczema or dermatitis.
Remember, it’s very important to consult with a healthcare professional before starting any new medication regimen. They will provide the best advice based on the cause of the itching and your overall health.
