Detalles del medicamento

Descripción

ellaOne es una píldora anticonceptiva de emergencia fabricada por HRA Pharma. Ayuda a prevenir el embarazo después de una relación sexual sin protección o cuando un método anticonceptivo ha fallado. Contiene acetato de ulipristal, un ingrediente activo que actúa retrasando o impidiendo la ovulación, por lo que no puede ocurrir la fertilización.

ellaOne es más eficaz cuando se toma lo antes posible, pero puede usarse hasta 5 días (120 horas) después de la relación sexual sin protección. Viene en una sola tableta fácil de tomar, ofreciendo una opción confiable de anticoncepción de emergencia.

ellaOne no protege contra infecciones de transmisión sexual (ITS) y no debe usarse como método anticonceptivo habitual. Si el embarazo ya ha comenzado, ellaOne no tendrá efecto. Para una protección continua, se recomienda usar un método anticonceptivo regular después de tomar ellaOne.
