Change to Tri-Regol from other oral contraceptives.

Seventy two women were recently controlled who changed to Tri-Regol. The women had used other oral contraceptive previously which they had not tolerated well. The aim of the change to Tri-Regol was successful in 77.7% partly successful in 12.5%, and unsuccessful in 9.8% of the cases. According to the author's opinion Tri-Regol is of high value in improving the tolerance of oral contraception in justified cases. In spite of the good results the change from Tri-Regol to tablets of higher hormone contents may also be justified in individual cases. The importance of the use of low-dose, triphasic tablets when starting oral contraception for lowering the risk of complications and side-effects has been emphasized as a currently generally recommended method.
