Hi thanks for your question.
Your uric acid level is 7.3 (for male normal up to 6) which is not very much high. You can control it by restricting you protein intake, especially red meat. Every medicine has side effect and Allopurinol
is no exception. The most common side effects of Allopurinol are;
,headache,sever blistering,pain or bleeding during urination,stomach upset
and sever tingling
Hope this answers your question.
