Capecitabine 500 mg chemotherapy tablets are regarded as an effective and successful oral chemotherapy drug. It is frequently used to treat cancers of the stomach, breast, and colon. Capecitabine is a prodrug that selectively targets and inhibits the growth of cancer cells by converting inside of these cells into 5-fluorouracil (5-FU).

The capecitabine 500 mg dosage varies according to the kind and stage of the cancer, as well as the patient's weight, kidney function, and general health. When treating colorectal or breast cancer, the usual standard dosage is 1,250 mg/m² twice a day for 14 days, with a 7-day break in between, in a 21-day cycle. Oncologists, however, frequently adjust the dosage to reduce adverse effects.

The daily maximum dosage of capecitabine is often limited to 2,500 mg/m2; however, this depends upon personal tolerance. Serious adverse effects include hand-foot syndrome, diarrhea, nausea, and exhaustion might result from higher dosages.
