Colchicine alters the way your body responds to uric acid crystals. Too much uric acid in the body is what leads to the symptoms of gout (swelling and pain).

Probenecid reduces the amount of uric acid in your body by causing it to be passed in your urine.

Colchicine and probenecid is a combination medicine used to prevent gout attacks. This medication will not cure gout and it will not stop a gout attack that has already started.

Colchicine and probenecid may also be used for purposes not listed in this medication guide.

Palliative treatment of metastatic breast cancer in postmenopausal women with estrogen-receptor positive or estrogen-receptor unknown tumors (designated an orphan drug by FDA for this use). Not recommended for treatment of estrogen-receptor negative breast tumors. Similar efficacy and toxicity as tamoxifen. Not known whether toremifene offers a therapeutic advantage over tamoxifen for the treatment of advanced breast cancer in eligible patients.

Under investigation for use as adjuvant therapy for early-stage breast cancer in node-positive postmenopausal women. Results from trials to date suggest similar efficacy and toxicity as tamoxifen.

Efficacy in treatment of advanced breast cancer in men not demonstrated.

Because of demonstrated cross-resistance with tamoxifen, usefulness of toremifene as second-line endocrine therapy for treatment of metastatic breast cancer refractory to tamoxifen appears to be limited.

Under investigation as a preventive agent for prostate cancer in men with high-grade prostatic intraepithelial neoplasia and no evidence of prostate cancer.
