If I use Vixpo tablets regularly for 4 months, can I have sex without additional protection (without a condom)?

The use of Vixpo contraceptive pills as prescribed effectively protects against pregnancy and there is no need to use additional methods of contraception. The average Pearl index for Vixpo tablets is 0.41 and the overall Pearl index (method failure + patient error) is 0.80. The Pearl Index is a standard measure of contraceptive effectiveness, indicating the number of undesirable fertilizations per 100 women using a given method of contraception per year (equivalent to 1,300 menstrual cycles). For comparison, the value of the Pearl index for a condom is in the range from 3 to 7.
