What follows is simply information for you to consider and not to be construed as medical advice. Gout is caused by too much uric acid in the blood and body tissues. The usual dosage of Allopurinol is 300mg/daily; however, you should go see a doctor who knows about gout (rheumatologist) rather than attempting to treat yourself. Allopurinol, the most common gout medication, can cause a severe, potentially life-threatening skin reaction called Stevens-Johnson syndrome (SJS) or toxic epidermal necrolysis (TEN), especially in individuals with the HLA-B*58:01 allele. My doctor gave me a blood test to check for that HLA-B*58:01 allele before starting me on Allopurinol. There are other medicines that can help, such as Benarone (benzbromarone) and Probenecid. Benzbromarone is a uricosuric agent and non-competitive inhibitor of xanthine oxidase used in the treatment of gout, especially when allopurinol, a first-line treatment, fails or produces intolerable adverse effects. Probenecid works by removing the extra uric acid from the body. Probenecid does not cure gout, but after you have been taking it for a few months it will help prevent gout attacks. Colchicine 0.6mg tablets are effective for acute gout attacks, but should be taken under a doctor's supervision, because if misused, colchicine can have toxic and even fatal effects. Many doctors recommend non-steroidal anti-inflammatory drugs (NSAIDS) such as Ibuprofen and Naproxen for the pain caused by gout attacks; however, you should consider that NSAIDS can have very deleterious effects on your kidney function. Once again, I strongly recommend that you see a doctor who specializes in the treatment of gout for the safest and most effective treatment.
P.S. - Being overweight is a risk factor. Drinking lots of water is essential to help flush out the uric acid. It is easy to find (on your choice of search engine) which foods to avoid; mainly foods that are high in purines, such as organ meats, red meat, chicken, and certain seafoods. Alcoholic beverages (particularly beer) should be avoided. I have read that eating cherries or drinking cherry juice may help reduce gout attacks. It is said that Vitamin C-rich foods may help lower uric acid levels.
