CCQ L contains letrozole that works in breast cancer by blocking an enzyme (aromatase) which prevents the conversion of androgens (androstenedione and testosterone) to estrogens (estrone and estradiol) due to this levels of estrogen hormones drop in the body. The decrease in hormone levels leads to a reduction in tumor mass or delays the progression of tumor growth in some women. For an ovulation (infertility), it is presumed that CCQ L works by increasing the sensitivity of ovary to follicular stimulating hormone (FSH) and also low level of estrogen hormones in the blood is detected by the brain which in turn increases the production of a follicular stimulating hormone (FSH) which causes induction of ovulation.

Yes, CCQ L may cause spotting or vaginal bleeding which is harmless. It is a very rare side effect of this drug. It might occur due to fluctuation in hormone levels in the body.

Rarely, CCQ L causes weight fluctuation (weight gain or weight loss). However, the exact cause behind weight fluctuation is unknown but it is presumed that this occurs due to fluctuation in hormone levels in the body caused by this drug. If you experience any unusual sudden weight gain or loss after taking this drug, then consult it with your doctor without further delay.

Dr. Rahul Poddar MBBS, DNB, MBBS, DNB , General Surgery

Take CCQ L once daily or as advised by your doctor. It has been taken with or without food because the presence of food does not affect the absorption of this drug from the stomach. Precautions must be taken in patients with osteoporosis, fracture, and improper liver function.
