Types and Causes of Pruritus
Pruritus, or itching, can take many forms. It depends on what causes it. Knowing the kinds of pruritus helps us find the right ways to treat it.
Inflammatory Pruritus
Inflammatory pruritus is common and links to skin issues like eczema. In about 60% of cases, inflammation causes strong itching and discomfort. Psoriasis and seborrheic dermatitis are shown to play a role, too.
Neuropathic Pruritus
Neuropathic pruritus comes from nerves not working right and makes about 25% of cases. It leads to ongoing and painful itching. For instance, postherpetic neuralgia and notalgia paresthetica point to nerve issues causing the itch.
Other Causes
Some pruritus cases, about 15%, come from different reasons. Diseases related to kidneys and liver can cause it. Medications and infections like tinea corporis and scabies might also be the culprit.
| Pruritus Type | Underlying Causes |
|---|---|
| Inflammatory Pruritus | Eczema, Psoriasis, Seborrheic dermatitis |
| Neuropathic Pruritus | Postherpetic neuralgia, Notalgia paresthetica |

Diagnosis and Treatment for Pruritus
Diagnosing pruritus involves looking at your whole health. Doctors use blood tests and check your thyroid. They do this to find out if a health problem is making you feel itchy.
The first choice to treat itch inflammation is with special creams. These creams, like hydrocortisone or tacrolimus, calm your skin and stop the itch.
If creams don’t help, you might see a skin doctor. They could suggest taking pills or getting shots. Medicines such as dupilumab and methotrexate are good for this.
Some itches are from nerve problems or a mix of causes. For these, doctors might recommend other skin creams or pills. Medicines like gabapentin, though not specifically for itching, are also helpful in some cases.
Stem cell therapy might also help with long-lasting itch problems. This brand-new treatment works to repair your skin from deep within. It could make a big difference in how much you itch.
