Are you experiencing itchy tiny blisters related to your RA or RA medications?
Tiny, itchy blisters can show up with RA for a few different reasons. It's worth paying attention to where they appear and when they started, as this can help your doctor figure out the cause.
Some common reasons this might be happening include:
- RA medications – DMARDs like methotrexate, biologics, and JAK inhibitors like Rinvoq can all cause itchy skin reactions or rashes. One myRAteam member described a "pimply rash between my fingers" from their RA medication.
- RA inflammation – Swelling and inflammation from RA itself can trigger itchy skin, particularly around the joints.
- Allergic reaction – Itchy, raised skin can sometimes signal an allergic reaction to a medication.
If the blisters appeared after starting or changing a medication, contact your doctor right away — it could be an allergic reaction that needs prompt attention.
In the meantime, some things that myRAteam members have found helpful for itchy skin include:
- Over-the-counter antihistamines like cetirizine (Zyrtec) or loratadine (Claritin)
- Topical corticosteroid creams
- Cool or warm compresses on the affected area
- Coconut oil for moisturizing dry, itchy skin
Always check with your healthcare team before trying new treatments, as some products can interact with RA medications.
