The best things to put on a shingles rash are cool compresses, calamine lotion, and numbing creams or patches containing lidocaine. These won’t cure shingles, but they directly target the burning, itching, and stinging that make the rash so miserable. What you apply depends on which stage the rash is in: active blisters, scabbing over, or lingering pain after healing.
Cool Compresses for Active Blisters
A clean, cool, damp washcloth applied directly to the rash is the simplest and most consistently recommended first step. The American Academy of Dermatology suggests applying it for 5 to 10 minutes at a time, several times a day. Cool temperature helps numb the skin’s surface and reduces the throbbing heat that shingles blisters produce. Use plain cool tap water, not ice, which can damage already inflamed skin.
For more thorough relief, you can soak the cloth in a diluted aluminum acetate solution (sold over the counter as Burow’s solution under the brand name Domeboro). Dissolve one or two packets in a pint of lukewarm water for a 1:40 dilution. Soak the cloth, wring it out, and lay it over the blisters for 15 to 20 minutes. This solution is both soothing and mildly antiseptic, and it helps break open weeping blisters and clean away crusted fluid. You can repeat this several times a day, especially if your blisters are oozing.
Calamine Lotion After Blisters Scab Over
Calamine lotion is a go-to for shingles itch. Its active ingredients, zinc oxide and iron oxide, create a cooling, drying layer on the skin that calms irritation and helps absorb any remaining moisture from healing blisters. The Cleveland Clinic specifically recommends applying calamine lotion directly to the skin alongside antiviral treatment for symptom relief.
Timing matters here. Dermatologists recommend waiting until the blisters have scabbed over before applying calamine lotion. During the active blister stage, stick with cool compresses. Once the rash is crusting and itchy rather than wet and oozing, calamine works well. Apply a thin layer with a cotton ball or clean fingertip and let it air dry. You can reapply as needed throughout the day.
Oatmeal Baths for Widespread Discomfort
If your rash covers a large area of your torso or wraps around your side (the most common pattern), soaking in a cool oatmeal bath can provide broader relief than spot-treating with compresses. Colloidal oatmeal, available at most drugstores, dissolves in water and forms a silky coating that reduces itching and inflammation across a wide surface area. Run a cool bath, not warm, since heat tends to intensify shingles pain. Soak for 15 to 20 minutes, then pat your skin dry gently with a clean towel rather than rubbing.
Lidocaine for Numbing the Pain
Over-the-counter lidocaine creams, gels, and patches work by temporarily blocking nerve signals in the skin. This is especially useful for shingles because the virus inflames the nerves directly, making even light touch from clothing or bedsheets feel like a burn. Lidocaine patches can be cut to size and placed over the most painful area, creating a barrier that also protects the rash from friction. The Mayo Clinic lists lidocaine in cream, gel, spray, and patch form among the standard topical treatments for shingles pain.
For pain that persists after the rash has healed (a condition called postherpetic neuralgia that affects some patients for months), prescription-strength lidocaine patches and capsaicin patches are common options your doctor may recommend.
Covering the Rash With Dressings
One often-overlooked option is simply covering the rash with a plain, non-stick transparent dressing like Tegaderm. A case study published in the Journal of Medical Case Reports found that applying these thin, adhesive film dressings directly over the blisters reduced pain to what the patient described as “an ignorable level.” The dressing works by shielding raw nerve endings from contact with clothing and shower water, two of the most common pain triggers during an active outbreak. Keep spare dressings on hand so you can replace them when they start to peel or bunch up.
Covering the rash also reduces the chance of spreading the virus to others. Shingles is contagious to people who have never had chickenpox, and the virus transmits through direct contact with blister fluid. A dressing keeps that fluid contained.
What Not to Put on the Rash
Hydrocortisone cream is not recommended for shingles. There is no evidence it helps with shingles pain, and it can further irritate already damaged skin. In general, thick moisturizers, petroleum jelly, and scented lotions should be avoided on the active rash because they can trap heat and moisture against blisters. Antibiotic ointments are also unnecessary unless a doctor has confirmed a secondary bacterial infection, which is a separate complication with distinct signs like increasing redness, warmth, swelling, or pus that looks yellow-green rather than the clear fluid of normal shingles blisters.
Topical Relief Is Only Part of Treatment
Everything above addresses symptoms, not the virus itself. Shingles is treated with prescription antiviral medications that work best when started within 72 hours of the rash appearing. These antivirals speed up healing, reduce the formation of new blisters, and lower the severity of acute pain. If you haven’t already started antiviral treatment and your rash appeared in the last few days, that’s worth prioritizing alongside any topical relief.
Managing pain aggressively during the acute phase may also reduce the risk of developing long-term nerve pain after the rash clears. Your doctor may recommend oral pain medications in addition to topical treatments, particularly if the rash is severe or the pain is disrupting sleep.
