Dosage for breast cancer

The typical recommended Truqap dosage for adults with breast cancer that is HR-positive and HER2-negative is 400 mg, taken twice per day (about every 12 hours). It’s taken for 4 days of the week and then not taken for the next 3 days. The cycle is then repeated each week of treatment.

You’ll do this on days 1, 2, 3, and 4 of the week. Then you’ll take no doses of Truqap on days 5, 6, and 7 of that week. You’ll repeat this schedule each week as long as you’re receiving Truqap treatment.
