[Our experience in using the triphasic contraceptive trisiston for contraception].

The authors carried out studies on 80 women, using Trisistone, a preparation of Germed, Jenapharm, DDR, in the course of 250 cycles, taking into consideration the advantages of triphasic contraceptive preparations as well as the fact that till this moment there were not applied in our country. A good contraceptive efficiency was established. No case with conception was recorded. The side effects were mild and and their frequency varies between 2.4 and 9.7% Irregular bleedings were the only disadvantage of Trisistone, which caused refusal for its usage. It is proposed that Trisistone should be used as an initial contraceptive preparation like the preparations with "mini" doses. In cases with good tolerance women should continue to use it, but they should take another contraceptive preparation, when bleeding occurs.
