Estradiol valerate and dienogest are synthetic versions of the naturally occurring female sex hormones, oestrogen and progesterone Qlaira tablet works just like many of the traditional birth control pills in that it prevents ovulation. The product is as effective as the traditional prescriptions. Testing in the United Kingdom has yielded an impressive 80 percent satisfaction rating.

How does Qlaira work?

Qlaira tricks your body into thinking that ovulation has already taken place; in doing so there is a very strong chance an egg will not be released during your menstrual cycle. Qlaira alters the consistency of the womb lining so that an egg can not implant itself there to grow, and thickens the cervical fluid making it tough for a sperm to entering the womb for fertilisation to take place.
