Taking too much vitamin C may make the urine more acidic and increase the possibility of kidney stones forming while you are taking allopurinol. Therefore, check with your doctor before you take vitamin C while taking this medicine.

• If you notice a skin rash, hives, or itching while you are taking allopurinol.
• If chills, fever, joint pain, muscle aches or pains, sore throat, or nausea or vomiting occur, especially if they occur together with or shortly after a skin rash .

Very rarely, these effects may be the first signs of a serious reaction to the medicine.
