Sudden Breathing & heart rate pause.

In July my mother is having irregular and heavy periods. They continuing from may and it's not stopping at all. We consulted an online dr, she prescribed trapic MF for heavy mens with cramps. The bleeding would stop but would suddenly will appear with heavy clots and lots of blood loss in a day. One pad will soak in few mints. Then We consulted a local dr, he prescribed, duoluton L, trapic MF. Yesterday at night she took both these tablet & after 12 hours later again. At 4Pm she started having sudden Breathing problem, nausea with vomiting. After some time her hands and feets started getting cold & she starts to become senseless, this continues for 2-3 hours, we tried to pump her chest, rub her hands, CPR as well. Dr plz tell me why this sudden Breathing and heart rate pause happened? I'm very very worried.plz tell!
