Pruritus (severe itching) with CKD: What helps?

I had severe itching when I was at stage 4, now, I'm 3b. I still get it for a couple of days, now and then. I can't pinpoint the culprit, but believe it has to do with eating foods too high in the 3 Ps...Protein, Potassium, Phosphorus. Or, having a meal that is higher in one of those, then feeling the effects for a few days. So, I try to switch my foods to lower levels of those all 3 for a few days. I too live in Mn, hands get very dry and irritated. I seem to be sensitive to hand lotions containing lanolin, so I try to avoid those. Eucerin eczema lotion helps a bit, but I haven't found a great solution yet.

@vpgh9246 Wow, this goes back a few years. aP stands for Associated Puritis and deals with severe itching for some such as myself at that time who had itching throughout my face and back, and much worse at night, causing some sleepless nights. I remember going to urgent care, an allergist and then a dermatologist who gave me an RX for Gabapentin, which cleared up the itching. If your husband has severe itching with Stage 4, talk to your nephrologist first, and if needed, follow up with my mentioned steps. I have found, like many others on this forum, for many years, a good habit to follow at any stage, is diet, exercise, and water. Get a baseline marker with your husband's nephrologist and stay close to that marker with your continuous lab work. My own personal opinion at stage 4 is to get a true kidney function test at any of the 3 Mayo Clinics or other educational research hospitals and get tested for iothalamate or iohexol exams, only because one kidney may be functioning better than the other, and your nephrologist may have some options. Obviously, I wish the best outcomes for your husband, you, and your family.

Pruritus (severe itching) is really common in chronic kidney disease (CKD), especially in later stages. It can happen even when labs don’t look extremely abnormal. Several things can help—some simple, some medical.

What Usually Helps CKD-Related Itching:

1. Keep the skin moisturized.

Dry skin makes CKD itching much worse.

Use thick, fragrance-free creams or ointments (CeraVe, Eucerin, Aquaphor, Vanicream).

Apply right after showering.

2. Avoid things that dry or irritate the skin:

Hot showers.

Scented soaps or lotions.

Wool or rough fabrics.

Strong detergents.

3. Check and manage common lab triggers:

Even mild imbalances can cause itching:

High phosphorus.

High parathyroid hormone (PTH)

High magnesium

Very dry skin from low sweat/oil production.

Improving phosphorus control often helps:

phosphate binders (if prescribed).

limiting processed foods with “phosphate” additives.

limiting dark sodas.

4. Medications that can help the itching>

Doctors often use:

Antihistamines (help some people, but CKD itching often isn’t histamine-based).

Gabapentin or pregabalin — one of the most effective options for CKD pruritus.

Difelikefalin (a newer drug sometimes used in dialysis patients).

Topical steroids only if there’s a rash or eczema component.

5. UV light therapy

If available, narrowband UVB phototherapy can reduce CKD itching. Dermatologists often use it when creams and meds don’t work.

6. Keep good kidney-related habits:

Control phosphorus.

Stay hydrated (if allowed).

Manage diabetes and blood pressure.

Follow the diet recommended for their CKD stage.

When to get medical help:

They should talk with their doctor if:

Itching is severe enough to affect sleep.

Skin becomes open, raw, or infected.

Labs haven’t been checked in a while.

They are on dialysis and itching is worsening.

@tommy901 Thanks for posting this! It confirms some of my theories on the foods possibly causing an imbalance.

@gwladj76 You're welcome! Glad that you gained some insight on this subject. Have a great day 😊
