Allopurinol: why does a new rash need immediate medical advice?

The cited allopurinol leaflets require immediate treatment cessation and immediate medical contact if a rash or skin symptoms appear. Do not wait for a prevention appointment to have this sign assessed.

The described signs extend beyond the skin. The leaflets mention mouth sores, red and swollen eyes, blisters and peeling skin. Fever, headache or body aches can precede a serious skin reaction.

The TEVA leaflet also describes severe allergic reactions involving swelling of the face or throat and difficulty swallowing or breathing. It requires immediate medical consultation. These manifestations need urgent medical help rather than a personal diagnosis.

Allopurinol acts on uric acid production. The cited leaflets describe its use to reduce or prevent urate deposits associated with gout and certain kidney stones. This role does not make a new rash harmless.

Both leaflets prohibit use in people with a known allopurinol allergy. Tell the treating professional about any prior reaction and name the product concerned. This information accompanies the medical assessment of a new rash.

For assessment, provide the exact product and other medicines taken now or recently. The leaflets specifically require disclosure of azathioprine and mercaptopurine, whose combination with allopurinol should be avoided. A professional checks the treatments; this list does not enable you to select a replacement yourself.
